VDZT2R2.0B Zener Diode Equivalent & Substitute Parts Reference

Part Overview

The Rohm Semiconductor VDZT2R2.0B is a surface-mount Zener diode designed for voltage regulation with a nominal Zener voltage of 2 V and a maximum power dissipation of 100 mW. It is housed in an SOD-723 (VMD2) package and is rated for operation in temperatures from -55°C to 150°C. The part is RoHS3 compliant and REACH unaffected. As VDZT2R2.0B is currently classified as obsolete, it becomes necessary to find suitable substitute models that match its key electrical and mechanical parameters for continued design and manufacturing support.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are selected strictly based on matching key parameters, which include manufacturer, Zener voltage (nominal), maximum power dissipation, operating temperature, mounting type, and compliance certifications. The substitute CDZVT2R2.0B is grouped due to alignment on Zener voltage, power rating, mounting configuration, environmental compliance, and part category.

Parameter Comparison

Engineering Selection Recommendations

The VDZT2R2.0B is obsolete, and the substitute CDZVT2R2.0B from Rohm Semiconductor is active, with ROHS3 compliance and REACH-unaffected classification matching the main part. The substitute shares core parameters such as Zener voltage, power rating, mounting type, and RoHS/REACH environmental certifications, aligning with requirements for direct replacement based on provided specifications.

Frequently Asked Questions (FAQ)

Q1: What are the critical parameters when selecting a substitute for VDZT2R2.0B?
A1: Critical parameters for substitution include nominal Zener voltage (2 V), maximum power dissipation (100 mW), operating temperature range, mounting type (surface mount), and package type, as well as compliance certifications (RoHS, REACH).

Q2: Is the mounting style and package of the substitute part compatible with the original?
A2: Both the original (VMD2/SOD-723) and substitute (VMN2M/SOD-923) parts use surface-mount technology. Package compatibility should be verified per physical dimensions when required.

Q3: Do both parts meet required environmental and regulatory certifications?
A3: Yes, both VDZT2R2.0B and CDZVT2R2.0B are ROHS3 compliant and REACH unaffected.

Q4: What is the product status difference between the two parts?
A4: VDZT2R2.0B is obsolete, while CDZVT2R2.0B is active and available.

Q5: Can both parts be used in applications with similar voltage and power requirements?
A5: Both parts are specified for 2 V Zener voltage and 100 mW power rating, aligning with the stated application requirements.
