Substitute Part Grouping Explanation

Substitute parts are grouped by matching the primary selection parameters: Zener diode function, Zener voltage (Nom), maximum power rating, mounting type, and compliance status. These criteria ensure that alternative parts are consistent with the original model’s electrical behavior and package requirements.

Key substitution parameters:

Zener voltage (Nom)
Maximum power dissipation
Mounting type (Surface Mount)
Compliance (ROHS3, REACH)

Only parts meeting or exceeding these specifications are considered valid substitutes.
