Component Sourcing
Component sourcing starts with a purchasing-ready BOM. Exact manufacturer part numbers, approved alternatives and clear quantities reduce ambiguity and let the sourcing review focus on availability, packaging, traceability and schedule.
Make each BOM line unambiguous
Include an exact MPN and manufacturer where possible. A value and package such as “10 kΩ, 0603” do not capture tolerance, power rating, voltage rating or material requirements. Keep reference designators and quantity consistent with the assembly data.
Manage shortages explicitly
Ask for a list of unavailable parts and proposed alternatives. Have engineering approve changes that can affect function, firmware, fit or qualification. Document the decision against the build revision.
Clarify purchasing and excess stock
Specify purchasing-channel restrictions and required traceability. Component packaging and order multiples can leave excess stock. Agree who pays for it, who owns it and whether it will be returned, retained or discarded.
What to include in your RFQ
- Complete BOM with exact MPNs
- Approved-alternate policy
- DNP and customer-supplied parts
- Traceability and handling requirements
- Excess-material ownership agreement
Confirm the process limits, material availability and acceptance criteria in your project quotation. They depend on the design and the manufacturing facility.
