Electronics companies work with short development cycles and long, fragile supply chains. A single product can combine thousands of electronic components, several PCB assemblies, mechanical parts, firmware, and software. And the product keeps changing after launch: a component goes end-of-life, a supplier changes, a PCB gets a new revision, a firmware update requires a hardware adjustment.
PLM is the environment that keeps the product definition, the BOM, engineering changes, and multidisciplinary engineering data connected through all of it. This guide explains what makes electronics product data hard to control, how six PLM platforms compare, and how to test them on the scenario that matters most: component obsolescence.
Electronics product data management: why it gets hard to control
One product exists across many engineering environments
Electronics product data rarely lives in one place. PCB designs sit in ECAD tools, enclosures and mechanical parts in MCAD, firmware in code repositories, BOMs in spreadsheets, purchasing data in the ERP, component information on supplier portals, and technical documentation in shared drives. Each tool holds part of the truth, and nobody holds the links between them.
Electronic designs change rapidly
During development, PCB layouts go through many revisions, components get substituted, firmware versions follow each other, and mechanical interfaces adjust to fit. Each change touches several of these environments at once. Without a common reference, the BOM in production quickly stops matching the design in engineering.
Engineering depends on external component data
Electronic components come from external manufacturers, through several distributors. Part numbers, manufacturers, specifications, approved suppliers, and lifecycle status all need to stay attached to the product definition. When that information lives only in a buyer's spreadsheet, engineering decisions rely on outdated data.
Hardware and software are increasingly inseparable
More and more electronic products run firmware or embedded software. Teams need to know which hardware revision works with which firmware version, and which combination each customer received. A change on one side can require a change on the other.
Electronics BOM management: more than a parts list
The bill of materials is where electronics complexity shows most clearly.
From engineering BOM to manufacturing BOM
The engineering BOM describes the product as designed: PCB assemblies, components, mechanical parts. The manufacturing BOM describes how it is built: assembly steps, consumables, packaging, and sometimes a different structure. Moving from one to the other by hand is one of the main sources of production errors. A PLM derives the manufacturing BOM from the engineering BOM and keeps the two linked.
Manufacturer part numbers and internal part numbers
An electronic component has an internal part number in your company and a manufacturer part number (MPN) from each manufacturer that makes it. When several manufacturers produce equivalent components, one internal part can correspond to several MPNs. Keeping that mapping clean is essential for both engineering and purchasing.
Approved vendor lists
An approved vendor list (AVL), or approved manufacturer list, defines which manufacturers and suppliers engineering has validated for each component. Purchasing can then buy from any approved source without asking engineering every time, and nobody buys an unvalidated part.
Alternates and substitute components
When a component is unavailable, teams often look for a substitute. Editing a spreadsheet to swap the part number is risky: the substitute may differ in footprint, rating, or behavior. A controlled process records the alternate, its validation, and the products where it applies.
BOM revisions and product variants
Electronics products often share a common platform with variants by market, customer, or configuration: a different power supply, a regional radio module, an extra sensor. The PLM must manage these variants in one structure and track each BOM revision, so every delivered configuration stays traceable.
Managing electronic component obsolescence with PLM
Why component obsolescence creates lifecycle risk
Electronic components have shorter lives than the products that use them. A semiconductor can go end-of-life while the product that contains it is still in production or under support contracts for years. Without preparation, an end-of-life notice can stop production, force a last-time buy, or trigger an urgent redesign.
Identifying where an obsolete component is used
The first question is always the same: which products, assemblies, and configurations contain this component? Where-used analysis answers it in seconds when the BOMs live in a PLM, and in days when they live in spreadsheets.
Finding and approving an alternative
Engineering then has to evaluate a replacement: electrical compatibility, footprint, availability, cost. The decision needs review and approval from engineering, quality, and purchasing, and a record of why that alternative was chosen.
Propagating the change
An approved alternative rarely affects only the BOM. It can require a PCB revision, updated technical documentation, new tests or qualification, manufacturing adjustments, new purchase orders, and updates to each product configuration concerned. The PLM has to carry the change through all of these, not just swap a line in a list.
At Aletiq, we believe component obsolescence is the most honest test of an electronics PLM: it shows in one scenario whether the platform really connects components, BOMs, changes, suppliers, and manufacturing.
Electronics PLM software comparison table
The platforms below differ in scope. Some are full enterprise PLM suites, others focus on cloud PLM for hardware teams, and one is centered on BOM management. Treating them as functionally identical would be misleading.
Aletiq
Aletiq is a cloud PLM for manufacturers, a strong fit for growing hardware companies and mid-market electronics manufacturers. It connects to ECAD tools, including Altium, as well as to major MCAD tools such as NX, SOLIDWORKS, CATIA, Creo, and Inventor, so PCB and mechanical data meet in one product structure. It manages part numbers and component data, builds BOMs, derives the manufacturing BOM from the engineering BOM, and handles product variants.
Engineering changes run through workflow models built with a visual editor, with impact analysis based on where each component is used, electronic signatures, and a full revision history. Configurable projects support new product introduction, and integrations with ERPs such as SAP, Infor, Sage, Cegid, and Dynamics 365 carry released BOMs to purchasing and production. Built-in AI lets teams search across product data and compare documents. On BOM management, Mecano ID, a space company with complex assemblies, cut the time it spends on BOMs by 70% with Aletiq.
Best for: hardware companies and mid-market electronics manufacturers that need ECAD and MCAD in one place, structured changes, and fast deployment without a dedicated PLM team.
Siemens Teamcenter
Teamcenter suits large electronics organizations with multidisciplinary products that combine mechanical, electrical, electronic, and software engineering. It is especially relevant for companies already working in the Siemens ecosystem, including Siemens' own electronics design tools. Its depth in configuration management and product structures comes with a long deployment and a dedicated PLM team. See our Siemens Teamcenter and NX alternatives.
Best for: large electronics enterprises with complex product structures and extensive engineering ecosystems.
PTC Windchill
Windchill covers product data, BOM management, configuration control, and engineering changes for complex hardware products, with dedicated capabilities for managing manufacturer and supplier parts. Its ECAD connections go through dedicated integrations. Like Teamcenter, it requires a significant implementation. See our PTC Windchill alternatives.
Best for: established manufacturers of complex hardware, often already using PTC tools.
Arena PLM
Arena, owned by PTC since 2021, is one of the best-known cloud PLM platforms for electronics and high-tech companies. Its strengths are BOM management with approved manufacturer and vendor lists, change control, supplier collaboration, NPI, and built-in quality processes. It is especially popular with companies that outsource manufacturing to contract manufacturers.
Best for: electronics and high-tech companies with outsourced manufacturing and strong supplier collaboration needs.
Duro
Duro is a cloud PLM built for hardware and electronics teams, designed to be quick to set up. Altium, the electronics design software vendor owned by Renesas, acquired Duro in December 2025, so its deepest integration is with Altium's design tools. It suits fast-moving teams whose engineering starts in Altium.
Best for: hardware startups and electronics teams working mainly in Altium.
OpenBOM
OpenBOM is a cloud platform centered on BOM and product data collaboration rather than a full enterprise PLM suite. It helps engineering teams build and share BOMs, catalogs, and part data, and connect them with CAD tools and purchasing. Its scope is narrower than a full PLM for engineering change processes and configuration management.
Best for: engineering teams that mainly need cloud-based BOM management and data sharing.
Electronics PLM comparison
Assessments are qualitative and based on each vendor's public positioning. Where a capability depends on an integration or an additional module, the table says so.
From prototype to mass production: what the PLM must control
An electronic product goes through six stages, and the PLM controls different information at each one.
How to test a PLM: the component obsolescence scenario
Use this scenario during demos:
A semiconductor used across four active products reaches end-of-life.
Ask each vendor to show how its platform helps teams:
- Identify every affected BOM
- Run a where-used analysis
- Identify the affected product configurations
- Launch an engineering change
- Evaluate an alternative component
- Update the relevant BOMs
- Coordinate engineering and purchasing
- Approve the new revision
- Preserve the previous configuration
- Communicate the change to manufacturing
How Aletiq handles the scenario
- The component page shows « Used in »: the four products, their assemblies, and the configurations that contain the semiconductor
- Engineering launches an engineering change from a workflow model; the right reviewers in engineering, quality, and purchasing get notified automatically
- The team documents the alternative component in Aletiq, with its data and the reason for the choice, and reviewers sign electronically
- Once approved, the new revision updates the BOMs concerned, and the previous configuration stays in the history for products already delivered
- The ERP integration sends the released BOMs to purchasing and production, so the new component reaches orders and the shop floor without manual re-entry
How to choose a PLM for electronics
- Hardware startup moving beyond spreadsheets: prioritize quick deployment, BOM control, revision management, simple change workflows, and a low administration burden. Cloud platforms such as Aletiq, Duro, or OpenBOM fit this stage
- Growing electronics manufacturer: prioritize NPI, supplier collaboration, ERP integration, component management, and product variants. Aletiq and Arena fit this profile
- Complex electromechanical manufacturer: prioritize ECAD and MCAD in one structure, multidisciplinary BOMs, configuration management, and change impact analysis. Aletiq covers this for mid-market companies; Teamcenter and Windchill for large engineering organizations
- Large electronics enterprise: prioritize scale, multiple engineering sites, complex integrations, product families, governance, and enterprise configuration management. Teamcenter and Windchill are the usual candidates
Conclusion
Electronics manufacturers should evaluate PLM around the realities of their products: BOM complexity, multidisciplinary engineering, and component lifecycle risk. The best platform for a hardware startup is rarely the best one for a multinational electronics manufacturer. Component obsolescence makes a particularly useful test, because it shows whether a platform connects engineering data, BOMs, suppliers, changes, and manufacturing. Run that scenario with every vendor on your shortlist rather than relying on standard demos.
