Key Parameters

Substitute Part Grouping Explanation

Substitute parts are identified based strictly on matching electrical and mechanical parameters: nominal Zener voltage, power rating, impedance, forward voltage characteristics at specified current, operating temperature range, mounting type, and package. Compliance information such as RoHS and REACH status, and product status, are equally considered to ensure equivalency in sourcing and application.

Key parameters used for substitution:

• Voltage - Zener (Nom) (Vz)
• Power - Max
• Impedance (Max) (Zzt)
• Voltage - Forward (Vf) (Max) @ If
• Operating Temperature
• Mounting Type
• Package / Case
• Supplier Device Package
• RoHS Status
• MSL
• REACH Status
• Product Status
