Substitute Part Grouping Explanation

Substitution logic for Zener diodes in the Diodes, Zener category is based strictly on the following allowed parameters: Zener voltage (nominal), tolerance, power dissipation, impedance, reverse leakage current at specified test voltage, forward voltage at given test current, operating temperature range, mounting type, package/case, RoHS compliance, and moisture sensitivity level. Substitute parts listed below share these critical parameters, allowing direct cross-referencing without introducing additional selection factors.
