Key Parameters

Substitute Part Grouping Explanation

Substitution is based strictly on the following essential parameters: Zener voltage, power rating, tolerance, maximum impedance, reverse leakage current, operating temperature, package type, mounting configuration, and compliance (RoHS, REACH, MSL). Only components that match or exceed these criteria, based on provided data, are included as substitutes. Package equivalency and compliance statuses are additionally enforced to ensure drop-in replacement in the intended PCB footprint and operating environment.

Parameter Comparison

Engineering Selection Recommendations

The primary part, CDZFHT2RA6.2B, is specified as "Not For New Designs." Substitute consideration should be focused on parts with equivalent Zener voltage, maximum impedance, reverse leakage, package compatibility, and compliance status. Substitute part DZ9F6V2S92-7 matches the required RoHS3 compliance, is REACH unaffected, and provides unrestricted MSL classification. Certification equivalency (excluding absence of explicit automotive/AEC-Q101 status) is based exclusively on supplied information.

Frequently Asked Questions (FAQ)

Q1: What are the key criteria for substituting a Zener diode in this category?
A1: Substitution requires matching nominal Zener voltage, maximum power, impedance, reverse leakage, tolerance, package type, mounting configuration, and compliance parameters such as RoHS and REACH status.

Q2: Are SOD-923 and VMN2 (SOD-923) packages physically compatible?
A2: Both the main and substitute parts specify the SOD-923 footprint. The supplier package notation "VMN2 (SOD-923)" indicates equivalence.

Q3: Does the DZ9F6V2S92-7 provide the same voltage and power characteristics as CDZFHT2RA6.2B?
A3: Both parts have a nominal Zener voltage of 6.2 V and matching impedance/reverse leakage characteristics, with DZ9F6V2S92-7 offering a higher maximum power rating.

Q4: Is automotive grade or AEC-Q101 qualification applicable to the substitute?
A4: The automotive grade and AEC-Q101 qualification are specified only for CDZFHT2RA6.2B. Equivalent qualification or grade for DZ9F6V2S92-7 is not provided in the current data.

Q5: How do compliance standards compare between main and substitute parts?
A5: Both CDZFHT2RA6.2B and DZ9F6V2S92-7 are ROHS3 compliant, have an MSL rating of 1 (unlimited), and are unaffected by REACH, matching compliance requirements.
