Substitute Part Grouping Explanation

Substitution is based strictly on the following allowed parameters: diode configuration, technology, maximum reverse voltage, average rectified current, forward voltage, speed, reverse leakage current, junction temperature, grade, qualification standard, mounting type, and package/case. Only parts matching these core parameters are considered valid substitutes in the Diodes, Rectifiers category.
