- Compare package, pinout, dimensions, voltage or rating fields, temperature range and compliance wording against the released BOM.
- Use the manufacturer datasheet or drawing for electrical and mechanical limits before approving a substitute.
RFQ fields SENICO needs
- Send exact part number, manufacturer, quantity, target delivery date, destination and required packaging.
- State whether alternates are allowed, and list any date-code, certificate, traceability or customer AVL requirement.
- Keep exact stock, factory lead time and proposed alternatives in separate quote lanes.
For PCA9539PW/Q900,118, SENICO recommends checking manufacturer marking, package, date code, requested quantity, approved vendor requirements and replacement risk before issuing a purchase order.
