Key Parameters

Substitute Part Grouping Explanation

Substitution is based strictly on matching the following key electrical and mechanical parameters: zener voltage (Vz), tolerance, maximum power dissipation, maximum impedance, reverse leakage current, and operating temperature. Mechanical compatibility is confirmed by matching mounting type and surface mount JEDEC package (SOD-923 form factor). Compliance and qualification are limited to the data specified, with both parts provided as RoHS3 compliant and not affected by REACH. Only parameters explicitly provided above are used for part equivalence.

Parameter Comparison

Engineering Selection Recommendations

CDZFHT2RA22B is designated Not For New Designs. CDZVT2R22B is indicated as Active. Both parts maintain RoHS3 compliance and are not affected by REACH. Moisture Sensitivity Level for both is 1 (Unlimited). Where automotive grade or AEC-Q101 qualification is required, review of explicit technical documentation may be necessary based on provided input. For ongoing designs, CDZVT2R22B meets the specified electrical and mechanical parameters for direct substitution within the Diodes, Zener category.

Frequently Asked Questions (FAQ)

Q: What core parameters must match for direct substitution between CDZFHT2RA22B and CDZVT2R22B?
A: Zener voltage, tolerance, power rating, maximum impedance, reverse leakage current, operating temperature, mounting type, package, and RoHS/REACH compliance must align.

Q: Are the package types VMN2 (SOD-923) and VMN2M (SOD-923) mechanically compatible?
A: Both are 2-SMD surface mount packages in the same SOD-923 form factor as specified.

Q: Does the substitute part maintain compliance and certification requirements?
