Services › BOM Review

BOM Review.
Cost, risk, and availability — before you order.

A thorough review of your Bill of Materials by a senior hardware engineer. We flag obsolete parts, sourcing risks, over-spec'd components, and cost reduction opportunities — before they become a production problem.

What we check

Four areas where BOMs go wrong — and cost you later.

Sourcing risk

Part availability & lifecycle

We check every critical component against distributor stock and manufacturer lifecycle status. NRND and EOL parts get flagged immediately. We also identify components with single-source risk or unusually long lead times.

  • → EOL / NRND flags
  • → Lead time analysis
  • → Single-source risk
  • → Preferred alternatives
Cost reduction

Over-spec'd & cheaper alternatives

Many BOMs contain components specified far beyond what the circuit requires. We identify over-spec'd parts and suggest cost-equivalent alternatives that meet the real performance requirements — without compromising margin.

  • → Voltage / current over-spec
  • → Tolerance over-spec
  • → Drop-in replacements
  • → Volume pricing opportunities
Compliance

RoHS, REACH & restricted substances

We check components for RoHS compliance and REACH SVHC declarations. If your product is going to the EU market, this is mandatory — and finding a non-compliant part after PCB assembly is an expensive problem.

  • → RoHS compliance flags
  • → REACH SVHC check
  • → Conflict minerals
  • → Compliant alternatives
Consistency

BOM integrity & schematic alignment

We cross-reference BOM line items against the schematic to catch mismatches, missing references, wrong values, and inconsistent footprint specifications. These errors cause assembly failures and manual rework charges.

  • → Value vs schematic mismatch
  • → Missing line items
  • → Footprint / MPN mismatch
  • → Duplicate reference designators
Deliverable

What you receive after the review.

We deliver a structured report with actionable findings — not a spreadsheet dump. Every flagged component comes with a specific recommendation and a rationale.

  • Annotated BOM with findings highlighted by category
  • Lifecycle status for all critical and flagged components
  • Cost reduction summary with estimated savings per line
  • Preferred alternatives with Mouser / DigiKey part numbers
  • Compliance table for RoHS and REACH-relevant items
  • Schematic mismatch log with reference designator and suggested fix
Sourcing risk
C12, C14 – CGA4J2X7R1H105K125AA

TDK has marked this capacitor as NRND (Not Recommended for New Design). Lead times at all major distributors currently exceed 26 weeks.

→ Replace with: GRM188R71H105KA93D (Murata, X7R 1µF 50V 0402) — direct drop-in, in stock at Mouser, ~30% cheaper at quantity.
Cost reduction
U5 – LM2596HVS-5.0 (3A rated)

The circuit draws a maximum of 600mA. The LM2596HVS-5.0 is rated for 3A and is significantly over-spec'd. No reason to carry the cost or the footprint.

→ Replace with: AP63200WU-7 (Diodes Inc, 2A, SOT-23-6) — smaller, cheaper, equally available. Save ~€0.85/unit at quantity.
Compliance
R3, R8 – RC0402JR-07 (non-RoHS suffix)

The ordered part number suffix indicates a non-RoHS variant. If selling into the EU market, this must be changed prior to assembly.

→ Replace with: RC0402JR-07100RL (Yageo, RoHS compliant suffix). Same value, same package, available immediately.
