DF10S2 Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The DF10S2 is a single-phase bridge rectifier manufactured by onsemi, rated for 1 kV peak reverse voltage and 2 A average rectified current. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The DF10S2 operates across a temperature range of -55°C to 150°C and is housed in a 4-SDIP surface mount package. Substitute parts must maintain electrical equivalence across voltage, current, and thermal specifications while accommodating different package designations from alternative manufacturers.

Substitute Part Grouping Explanation

Substitute parts for the DF10S2 are qualified based on strict electrical and mechanical parameter matching. All substitute candidates maintain the following core specifications:

Voltage - Peak Reverse (Max): 1 kV
Current - Average Rectified (Io): 2 A
Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 2 A
Operating Temperature Range: -55°C ~ 150°C (TJ)

Substitute parts are sourced from manufacturers including Taiwan Semiconductor Corporation, Diodes Incorporated, Panjit International Inc., MDD, Comchip Technology, and Good-Ark Semiconductor. While supplier device packages vary (4-SDIP, ABS, 4-SOPA, DBS, DFS, ABF), all maintain mechanical compatibility with 4-SMD gull wing surface mount footprints. Current - Reverse Leakage @ Vr specifications range from 3 µA to 10 µA @ 1000 V across the substitute population, all within acceptable operational parameters.

Engineering Selection Recommendations

For new designs and production applications, active product status parts are preferred. ABS20M, ABS210-13, ABS2MS_R2_00101, DB207S, and LB2010S are all currently active and available in production quantities. All substitute parts maintain ROHS3 compliance or equivalent RoHS compliance status, meeting environmental and regulatory requirements.

The DF10S2 and DF210ST-G are both classified as obsolete. While DF210ST-G remains available in limited inventory (1022 pcs), it shares obsolete status with the original part. For long-term supply chain stability, selection from the active product group is recommended.

Current - Reverse Leakage @ Vr varies across the substitute population. The DF10S2 specifies 3 µA @ 1000 V, while substitute parts range from 5 µA to 10 µA @ 1000 V. All values remain within acceptable operational parameters for single-phase bridge rectifier applications.

Frequently Asked Questions (FAQ)

Q: Can I substitute the DF10S2 with any of the listed parts?

A: Yes. All listed parts maintain identical electrical specifications for voltage, current, and temperature range. The DF10S2 operates at 1 kV peak reverse voltage, 2 A average rectified current, and -55°C to 150°C junction temperature. All substitute parts match these core parameters.

Q: Do package differences affect compatibility?

A: All substitute parts use 4-SMD gull wing surface mount packages. While supplier device package designations differ (4-SDIP, ABS, 4-SOPA, DBS, DFS, ABF), the mechanical footprint and pin configuration remain compatible with DF10S2 PCB layouts.

Q: What is the difference between the DF10S2 and DF210ST-G?

A: Both parts are obsolete and share identical electrical specifications. DF210ST-G is manufactured by Comchip Technology with 1022 pcs available inventory, while DF10S2 is manufactured by onsemi with 753 pcs available inventory. Both operate at 1 kV, 2 A, and -55°C to 150°C.

Q: Which substitute part has the lowest reverse leakage current?

A: The DF10S2 specifies 3 µA @ 1000 V reverse leakage. Among active substitute parts, ABS20M, ABS210-13, ABS2MS_R2_00101, and LB2010S all specify 5 µA @ 1000 V. DB207S specifies 10 µA @ 1000 V.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts are either ROHS3 Compliant or RoHS Compliant, meeting environmental and regulatory requirements.

Q: Which substitute parts are currently in active production?

A: ABS20M, ABS210-13, ABS2MS_R2_00101, DB207S, and LB2010S are all active products. DF10S2 and DF210ST-G are obsolete.
