Substitute Part Grouping Explanation

Substitute parts for the CDZVT2R22B Zener diode are strictly selected based on a set of parametric criteria. Substitution is permitted only when the following parameters are matched: nominal Zener voltage (Vz), tolerance, maximum power, maximum impedance (Zzt), reverse leakage current at specified voltage, operating temperature, mounting type, package/case, supplier device package, and compliance details (RoHS, MSL, REACH, ECCN, HTSUS). No other criteria are considered for equivalence. The parametric equivalent listed, CDZFHT2RA22B, is grouped as a substitute based solely on these provided attributes.

Parameter Comparison

Engineering Selection Recommendations

The main part number CDZVT2R22B is identified as active with ROHS3 and REACH compliance. The parametric equivalent CDZFHT2RA22B is designated as not for new designs but maintains the same compliance and environmental certifications. For selection, it is required to consider product status and qualification where automotive grade and AEC-Q101 qualification are present for CDZFHT2RA22B. Both parts satisfy MSL 1 and have matched regulatory statuses.

Frequently Asked Questions (FAQ)

Q1: What parameters are critical for substituting Zener diodes in the VMN2M (SOD-923) package?
Substitution requires that nominal Zener voltage, tolerance, power rating, maximum impedance, reverse leakage current, operating temperature, mounting type, package/case, supplier device package, and compliance information are strictly matched.

Q2: Is CDZFHT2RA22B directly pin-compatible with CDZVT2R22B?
Both are supplied in surface mount 2-SMD packages with flat leads in the SOD-923 family, aligning key mechanical footprints. Differences in supplier device package naming (VMN2M vs VMN2) do not affect compatibility within the provided parameters.

Q3: Does the substitute part CDZFHT2RA22B offer the same compliance certifications as CDZVT2R22B?
ROHS3, MSL 1, REACH unaffected, ECCN EAR99, and HTSUS 8541.10.0050 are matched between both part numbers.

Q4: What product status constraints affect substitute selection?
CDZVT2R22B is active, while CDZFHT2RA22B is not for new designs. Selection for ongoing or new designs should be guided by product lifecycle status as provided.
