DF210ST-G Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The DF210ST-G is a single-phase bridge rectifier manufactured by Comchip Technology, rated for 1 kV peak reverse voltage and 2 A average rectified current. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The DF210ST-G features a 4-SMD Gull Wing surface mount package (DFS) and operates across the temperature range of -55°C to 150°C.

Substitute Part Grouping Explanation

Substitution for the DF210ST-G is determined by strict electrical and mechanical parameter matching. All substitute parts must meet the following criteria:

Single-phase bridge rectifier topology
1 kV peak reverse voltage rating
2 A average rectified current capability
Surface mount 4-SMD Gull Wing package configuration
Operating temperature range of -55°C to 150°C
ROHS3 compliance or equivalent environmental certification

Substitute parts are grouped into two categories: manufacturer-recommended direct substitutes and parametric equivalents. Manufacturer-recommended substitutes share identical electrical specifications and package designations. Parametric equivalents meet all electrical requirements but may originate from different manufacturers with alternative package designations (such as SDB-1, ABS, 4-SOPA, or ABF) while maintaining mechanical compatibility in the 4-SMD Gull Wing form factor.

Engineering Selection Recommendations

Primary Recommendation: DF210S-G

The DF210S-G from Comchip Technology is the direct manufacturer-recommended substitute for the obsolete DF210ST-G. This part maintains identical electrical specifications, forward voltage characteristics, and reverse leakage parameters. The DF210S-G carries active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment. Packaging is identical (4-SMD Gull Wing DFS), requiring no PCB layout modifications.

Secondary Recommendations: SDB207-TP and SDB207-TP-HF

The SDB207-TP and SDB207-TP-HF from Micro Commercial Co are direct manufacturer-recommended alternatives. Both maintain the 1 kV / 2 A electrical specification and operating temperature range. Forward voltage is specified at 1.2 V @ 2 A, representing a 0.1 V increase over the DF210ST-G. Both parts carry ROHS3 compliance and active product status. The SDB207-TP is supplied in Tape & Reel packaging, while SDB207-TP-HF is available without specified packaging. Both use the SDB-1 package designation but maintain mechanical compatibility with the 4-SMD Gull Wing form factor.

Tertiary Recommendations: ABS20M, ABS210-13, ABS2MS_R2_00101, DB207S, and LB2010S

These parametric equivalents meet all electrical requirements with identical or superior reverse leakage characteristics (5 µA vs. 10 µA). All carry ROHS3 compliance and active product status. Forward voltage specifications match or are lower than the original part. Package designations vary (ABS, 4-SOPA, DBS, ABF) but all maintain the 4-SMD Gull Wing surface mount configuration. These parts are suitable for applications where manufacturer diversity is required or where inventory availability is a consideration.

Frequently Asked Questions (FAQ)

Q: Can I use SDB207-TP as a direct replacement for DF210ST-G?

A: Yes. The SDB207-TP meets all electrical specifications: 1 kV peak reverse voltage, 2 A average rectified current, and -55°C to 150°C operating temperature. The forward voltage specification of 1.2 V @ 2 A is within acceptable tolerance for most applications. Both parts use 4-SMD Gull Wing surface mount packages and are ROHS3 compliant. No PCB modifications are required.

Q: What is the difference between the parametric equivalents and manufacturer-recommended substitutes?

A: Manufacturer-recommended substitutes (DF210S-G, SDB207-TP, SDB207-TP-HF) are designated by the original or alternative manufacturers as direct replacements with identical or near-identical specifications. Parametric equivalents (ABS20M, ABS210-13, ABS2MS_R2_00101, DB207S, LB2010S) meet all electrical requirements but originate from different manufacturers and may use alternative package designations. All are electrically compatible.

Q: Does the reverse leakage difference between 5 µA and 10 µA matter?

A: The reverse leakage specification indicates the maximum leakage current at rated reverse voltage. Lower leakage (5 µA) represents superior performance characteristics. Parts with 5 µA leakage (ABS20M, ABS210-13, ABS2MS_R2_00101, LB2010S) are suitable for all applications where the DF210ST-G was used. The difference is not a limitation but rather an improvement in parametric performance.

Q: Are all substitute parts ROHS3 compliant?

A: All recommended substitute parts carry ROHS3 compliance or equivalent environmental certification. The DB207S from MDD is specified as RoHS Compliant. All other parts are explicitly ROHS3 Compliant. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for all parts, indicating no special moisture handling requirements.

Q: Can I mix different substitute parts in the same design?

A: Yes. All substitute parts maintain identical electrical specifications for voltage rating, current capacity, and operating temperature range. They all use 4-SMD Gull Wing surface mount packages. PCB footprints are compatible across all listed parts. Design consistency and supply chain considerations should guide part selection.

Q: What packaging options are available?

A: DF210S-G is supplied in Tube packaging. SDB207-TP is supplied in Tape & Reel (TR). ABS20M, ABS2MS_R2_00101, and LB2010S are supplied in Tape & Reel (TR). ABS210-13 is supplied in Cut Tape (CT) & Digi-Reel®. SDB207-TP-HF and DB207S have unspecified packaging. Packaging selection depends on assembly volume and handling requirements.
