BOM analysis & review
Line-by-line review for lifecycle status, sourcing depth, specification gaps and cost drivers.
Discuss thisDesign & SimulationComponent sourcing and lifecycle
Component sourcing and lifecycle
so your BOM can still be built in three years.
A design is only as maintainable as its bill of materials. We review BOMs for lifecycle risk, availability and second sources, qualify alternates that actually drop in, and flag the parts most likely to cause a production stop.

Why sourcing derails productionA part on the BOM is not
A part on the BOM is not
the same as a part you can buy.
Most sourcing emergencies are visible long in advance: a part entering end-of-life, a single-source connector, a manufacturer consolidating a product line, or a component that is quoted at a volume that no real buyer reaches. None of these are obvious if the BOM is treated as a static list.
We assess each line for lifecycle status, sourcing depth, lead time and substitution risk, then qualify alternates electrically and mechanically so a change is a planned activity rather than an emergency.
Cost is one factor, not the answer. A cheaper part with a longer lead time or a single source can cost more than the part it replaces.
- 01Lifecycle status checked
Each part assessed for lifecycle stage, longevity and end-of-life exposure.
- 02Single sources flagged
Parts with no realistic second source identified early, when a plan can still be made.
- 03Alternates actually qualified
Substitutions checked electrically, mechanically and thermally rather than assumed equivalent.
- 04Cost seen in full
Pricing considered alongside lead time, MOQ, lifecycle and assembly impact.
- Lifecycle visibilityStatus and longevity assessed per line, so end-of-life exposure is known before it bites.
- Supply depth reviewedSingle-source and constrained parts identified and flagged for planning.
- Alternates qualifiedCandidate parts verified against the original electrically and mechanically.
- Total cost consideredPrice weighed against lead time, MOQ, lifecycle risk and assembly consequences.
What we deliver
Component sourcing services
Sourcing support can be a one-off BOM review or ongoing supply management alongside an engineering programme.
Lifecycle risk assessment
End-of-life exposure, longevity and supply continuity reviewed against your product roadmap.
Discuss thisAlternate part qualification
Candidate alternates compared electrically, mechanically and thermally before approval.
Discuss thisObsolescence management
Last-time-buy planning, redesign options and lifecycle mitigation for affected parts.
Discuss thisSupplier & distributor sourcing
Sourcing strategy across manufacturers, authorised distributors and assembly partners.
Discuss thisCost reduction review
Specification, quantity and sourcing options reviewed for real, sustainable savings.
Discuss thisWhat is included in scope
Scope is agreed in writing before work starts, so deliverables and responsibilities are clear.
- BOM intake & clean-upPart numbers, specifications and quantities captured, with duplicates and inconsistencies identified.
- Lifecycle & availability auditEach line checked for lifecycle stage, longevity, lead time and sourcing depth.
- Risk rankingParts ranked by production impact, so the highest-risk items are addressed first.
- Alternate identificationCandidate alternates identified and compared against the original specification.
- Qualification & approvalAlternates verified electrically, mechanically and thermally, then approved for use.
- Supply planSourcing strategy, buffers and lifecycle mitigation documented for ongoing builds.
Capabilities
Sourcing and lifecycle capability
Engineering judgement matters here: two parts sharing a description does not mean they are interchangeable on your board.
BOM review & clean-up
Duplicates, inconsistent specifications and missing data corrected at source.
Lifecycle intelligence
Status, longevity and end-of-life exposure assessed for every critical line.
Alternate qualification
Alternates compared on electrical, timing, thermal and mechanical characteristics.
Obsolescence planning
Last-time-buy, redesign and mitigation options prepared before stock runs out.
Cost optimisation
Specification, quantity and sourcing options reviewed for sustainable reduction.
Supply chain support
Distributor and manufacturer relationships used to protect lead times and availability.
Cost modelling for the whole product sits in cost & BOM analysis. Where a part genuinely does not exist, see VLSI & ASIC design.
Our process
How a sourcing review runs
Audit the BOM, rank the risk, qualify alternates, then document a supply plan.
BOM audit
Every line reviewed for specification, lifecycle status, availability and sourcing depth.
BOM auditRisk ranking
Parts ranked by production impact, with single sources and end-of-life items highlighted.
Risk reportAlternate qualification
Candidate alternates identified and verified electrically and mechanically.
Approved alternatesSupply plan
Sourcing strategy, buffers and lifecycle mitigation documented and handed over.

Technologies
Sourcing approach and tools
Decisions are based on documented manufacturer data and real distributor availability, not catalogue listings alone.
- Lifecycle dataManufacturer lifecycle status, longevity and end-of-life announcements reviewed per part
- Availability dataStock, lead time and MOQ checked with authorised distributors before commitment
- Specification comparisonDatasheet-level comparison of alternates across electrical and timing parameters
- Approved vendor listsAVL discipline applied so every purchased part has a controlled source
- Cost modellingVolume pricing, MOQ tiers and total landed cost compared properly
- Obsolescence planningLast-time-buy quantities and redesign options planned against product lifecycle
A part available only on the open market is a supply risk, not a sourcing strategy. We work through authorised channels wherever the part allows it.

Illustrative · Legacy product
A controller that entered end-of-life
Challenge: The main processor was discontinued with a two-year notice.
Approach: Alternates identified and qualified, with a last-time-buy plan covering remaining demand.

A bill of materials with hidden cost drivers
Challenge: Unit price was the only factor considered when selecting parts.
Approach: Specification, quantity and sourcing options reviewed, showing where real savings were available.
Explore cost & BOM analysisIllustrative · New design
A design that needed a second source
Challenge: A single-source connector created a dependency with no fallback.
Approach: Equivalent connectors qualified on mechanical and electrical fit, then added to the approved list.

What buyers usually want to know before scoping this kind of work.
Ask about your requirements →What component sourcing services do you offer?
BOM analysis, lifecycle risk assessment, alternate part qualification, obsolescence management, supplier and distributor sourcing, and cost reduction review.
How do you identify parts at end of life?
Manufacturer lifecycle announcements and status data are reviewed per part, then assessed against your product roadmap so exposure is understood early rather than discovered at purchase.
Are alternates guaranteed to be drop-in replacements?
No part is guaranteed without checking. We compare alternates on electrical, timing, thermal and mechanical characteristics and report the differences, so you can decide what needs re-verification.
Do you work with an existing BOM?
Yes. Send the current bill of materials and we will audit it for lifecycle risk, sourcing depth, specification gaps and cost drivers, then rank the findings by production impact.
Can you reduce cost without breaking the design?
Often, yes. Specification, quantity and sourcing options are reviewed, but we will flag when a saving depends on a part that changes behaviour, tolerance or reliability.
Do you handle obsolescence for parts already in production?
Yes. We assess the impact, identify last-time-buy quantities where appropriate, and outline redesign options for parts with no qualified replacement.
