Substitute Part Grouping Explanation

Substitution is determined by matching specific electrical, mechanical, and compliance parameters. Acceptable substitutes must share Schottky technology, a maximum DC reverse voltage of 50 V, average rectified current of 2A, a forward voltage of 700 mV at 2A, SMB (DO-214AA) packaging, surface-mount configuration, automotive grade, and AEC-Q101 qualification. Compliance with RoHS3, REACH, ECCN, and MSL is required for compatibility in regulated environments. All substitute relationships are limited to models explicitly listed and matched to these parameters.
