VDZT2R13B Equivalent & Substitute Parts Reference

Part Overview

The VDZT2R13B, manufactured by Rohm Semiconductor, is a surface-mount Zener diode with a nominal Zener voltage of 13 V, a maximum power dissipation of 100 mW, and a tolerance of ±2%. The part is supplied in a VMD2 (SOD-723) package and is classified as obsolete. For ongoing designs or inventory replacement, identification of substitute Zener diodes with strictly matching electrical and mechanical parameters is essential to maintain product reliability and compliance.

Substitute Part Grouping Explanation

Substitutes are selected based on strict equivalency of the following key parameters:

Zener Voltage (13 V nominal)
Tolerance (±2% or closest available)
Maximum Power Dissipation (≥100 mW)
Maximum Impedance (Zzt) (matching or lower)
Reverse Leakage Current at test voltage
Operating Temperature Range
Mounting type (Surface Mount)
Regulatory compliance (ROHS3, MSL, REACH)
Package/case similarities

Only diodes that match or exceed the performance and compliance requirements listed above are considered equivalent or substitute components in the Zener diodes category. Substitutions are listed separately by exact match, parameter equivalence, and similarity in package.

Engineering Selection Recommendations

Selection among substitute Zener diodes should consider the product status to ensure ongoing supply. All candidate substitutes (CDZVT2R13B, CDZT2RA13B, BZX884-B13,315) are listed as active and maintain ROHS3 compliance, MSL 1 (Unlimited), and REACH unaffected status. These compliance and certification attributes match the main part requirements for regulated or environmentally conscious designs.

Frequently Asked Questions (FAQ)

Q1: What key parameters must match when selecting a substitute for VDZT2R13B?
A1: Key matching parameters include Zener voltage, tolerance, maximum power, impedance, reverse leakage current, operating temperature, mounting type, package/case, and compliance status.

Q2: Are package differences significant between VDZT2R13B and its substitutes?
A2: Substitute parts may be supplied in different miniature surface-mount package types (e.g., SOD-923, DFN1006-2). Ensure package compatibility with PCB footprints before direct replacement.

Q3: Can differences in reverse leakage or impedance impact substitution?
A3: Substitutes are selected with reverse leakage current and impedance values that are either identical or maximally constrained to the original specification.

Q4: Do all substitutes meet regulatory compliance?
A4: All listed substitute Zener diodes are ROHS3 Compliant, have MSL 1 (Unlimited), and are REACH unaffected.

Q5: Why is substitution necessary for VDZT2R13B?
A5: VDZT2R13B is designated as obsolete, making continued sourcing impractical for ongoing designs or replacement needs. Only active status parts with strict parameter matching are suitable alternatives.
