Start with the original part identity
Keep the manufacturer and complete manufacturer part number on every BOM line. Preserve punctuation, package and packing suffixes. An internal reference can be included in a separate column, but should not replace the original MPN.
Make the purchasing need clear
Add the required quantity, preferred purchase quantity if different, target delivery date and delivery destination. State whether partial deliveries are acceptable. Price, stock and lead time still require confirmation for the actual request.
Include documentation and inspection needs
Describe required traceability records, inspection reports, packaging conditions and any approved sourcing restrictions. For PCBA or project supply, identify the BOM revision and any customer-approved component list.
Keep alternatives under engineering control
Do not treat a shared series prefix or a text-similar search result as an approved replacement. Submit alternatives as separate lines only after the responsible engineering team has reviewed them.
Review before submitting
