Electronic Components Supplier Evaluation Guide

Part identity and source

• Control manufacturer part number, package, grade and revision instead of accepting description-level substitutes.
• Record whether supply is authorized, franchised, brokered or customer-supplied and apply risk controls accordingly.
• Check lifecycle and allocation risk for components that can stop production.

Quality evidence

• Require traceability and handling evidence appropriate to component risk and product requirements.
• Define incoming inspection and escalation for suspect, damaged or nonconforming material.
• For brokered or obsolete parts, apply enhanced authenticity and test requirements rather than relying on visual appearance alone.

Commercial normalization

• Compare minimum order, pack quantity, lead time, freight, duties and cancellation terms on the same basis.
• Include shortage and line-stop exposure in sourcing decisions for critical parts.
• Maintain approved-source and alternates records so urgent purchases still follow controlled engineering decisions.

Professional references

Commercial independence

PROFENG may display a separately disclosed approved partner after the engineering content. Partner status never changes formulas, conversion factors, procurement criteria, technical references or calculation results. Pending and unapproved programs remain hidden.
