REVIEW FRAMEWORK

Every candidate must survive four questions.

Package, footprint, dimensions and assembly constraints.

Fit

Pinout, ratings, interfaces and electrical compatibility.

Function

Performance, firmware, qualification and application risk.

Commercial

Lifecycle, availability, MOQ, lead time and cost.
