Engineering Selection Recommendations

Selection of Zener diodes for substitution should prioritize product status and compliance details. CDZT2R12B is Not For New Designs, while NZ9F12VST5G has Active status. Both are ROHS3 Compliant and have REACH status of Unaffected. Moisture Sensitivity Level for both is 1 (Unlimited), ensuring unlimited floor life in production. Environmental and compliance equivalence is maintained across both variants.

Frequently Asked Questions (FAQ)

Q1: What are the primary parameters for substituting the CDZT2R12B Zener diode?
A1: Main parameters include Voltage - Zener (Nom) (Vz), Tolerance, Power - Max, Impedance (Max), Current - Reverse Leakage, Mounting Type, Package / Case, and compliance attributes such as RoHS and REACH status.

Q2: Are the physical package and mounting type identical between CDZT2R12B and NZ9F12VST5G?
A2: The CDZT2R12B uses the 2-SMD, Flat Lead (VMN2/SOD-923) package and NZ9F12VST5G uses SOD-923. Both are surface-mount and utilize the SOD-923 format.

Q3: How does product status impact substitute choice?
A3: CDZT2R12B is Not For New Designs; NZ9F12VST5G is listed as Active. For ongoing or new designs, selecting a part with Active status is preferable based on lifecycle considerations.
