Equivalent & Substitute Parts for EDZVT2R9.1B

Part Overview

EDZVT2R9.1B from Rohm Semiconductor is a surface-mount Zener diode with a nominal breakdown voltage of 9.1 V and a maximum power dissipation of 150 mW. Classified under the Diodes, Zener category, it features precise voltage regulation (±2% tolerance) and is presented in the EMD2 (SOD-523) package. The part is actively available and compliant with ROHS3 and REACH standards. In many applications, engineers require alternate part numbers to address inventory continuity, qualification processes, and supply chain resilience. Alternate Zener diodes must meet electrical and mechanical compatibility to serve as functional substitutes.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for Zener diodes such as EDZVT2R9.1B are selected strictly on the basis of equivalent Zener voltage, power dissipation, package compatibility, and compliance standards. Substitution is valid when the following key parameters match or closely align: Voltage - Zener (Nom), mounting type, package/case, product status, and RoHS/REACH/ECCN certifications. Only parts listed with explicitly provided parameters are included as substitutes.

Parameter Comparison

Engineering Selection Recommendations

Both EDZVT2R9.1B and CMOZ9L1 TR PBFREE share active product status and are ROHS3 and REACH compliant with identical ECCN and HTSUS classifications. Moisture sensitivity level (MSL: 1) and mounting configurations are equivalent. These factors allow for direct selection based on supply chain or qualification requirements, provided only the specified electrical and mechanical criteria are considered.

Frequently Asked Questions (FAQ)

Q1: What parameters are critical for substituting Zener diodes in the same category?
Allowed parameters for substitution include Zener voltage, power dissipation, mounting type, package/case, and compliance certifications. These must be matched as provided.

Q2: Does difference in supplier device package designation affect compatibility?
If both parts specify SC-79, SOD-523 packages, as in the provided input, they are compatible for surface-mount designs.

Q3: What certifications are required for equivalent substitution?
Parts must have matching ROHS3, REACH, ECCN, and HTSUS status for regulatory compliance.

Q4: Is tolerance a strict substitution criterion?
Tolerance is an electrical parameter to be considered; only parts with listed tolerance values can be directly evaluated for equivalence.

Q5: Is active product status mandatory for substitute selection?
Substitute must have an active product status to ensure ongoing support and availability.

Q6: Are all mechanical parameters identical between main and substitute parts?
Package/case and mounting type data provided are identical for both parts, supporting direct substitution in corresponding footprints.
