Substitute Part Grouping Explanation

Substitution is determined by strictly matching electrical and mechanical parameters, including voltage rating, current rating, forward voltage, reverse leakage, switching speed, mounting type, qualification, package, temperature range, and compliance specifications. Only parts with identical or explicitly listed parametric matches are allowed as substitutes. For this category, parametric equivalents meet the same Schottky technology, 40 V maximum reverse voltage, 8A average rectified current rating, forward voltage drop, DO-214AB (SMC) package, automotive grade with AEC-Q101 qualification, and ROHS3/REACH compliance.

Key substitution parameters:
