ABS2-G Bridge Rectifier Equivalent & Substitute Parts
Part Overview
The ABS2-G is a single-phase bridge rectifier diode manufactured by Comchip Technology, rated for 200 V peak reverse voltage and 1 A average rectified current. This component is classified as obsolete, which necessitates identification of active equivalent and substitute parts for ongoing design requirements and procurement needs. The ABS2-G operates across a temperature range of -55°C to 150°C and is packaged in a 4-SMD, Gull Wing surface mount configuration. Equivalent parts maintain identical or superior electrical performance while substitute parts provide functional compatibility within the specified parameter ranges.

- Current - Average Rectified (Io): 1 A minimum
- Diode Type: Single Phase
- Technology: Standard
- Mounting Type: Surface Mount
- Package / Case: 4-SMD, Gull Wing configuration
- Operating Temperature Range: -55°C to 150°C minimum
Secondary Compatibility Parameters:
- Voltage - Forward (Vf) (Max) @ If: 1.1 V or lower at 1 A
- Current - Reverse Leakage @ Vr: 5 µA or lower at 200 V
- RoHS3 Compliance

Engineering Selection Recommendations
Primary Recommendation: ABS2-HF
The ABS2-HF is the manufacturer-recommended direct replacement for the obsolete ABS2-G. Both parts are manufactured by Comchip Technology and maintain identical electrical specifications across all critical parameters: 200 V peak reverse voltage, 1 A average rectified current, 1.1 V maximum forward voltage at 1 A, and 5 µA reverse leakage current at 200 V. The ABS2-HF is currently in active production status with 857 units in stock. This part is ROHS3 compliant and carries MSL rating 1 (Unlimited).
Secondary Recommendations: ABS2U, DF02S-E3/77, DF02SA-E3/77
The ABS2U (SMC Diode Solutions), DF02S-E3/77 (Vishay), and DF02SA-E3/77 (Vishay) are parametric equivalents with identical electrical performance to the ABS2-G. All three parts maintain 200 V peak reverse voltage, 1 A average rectified current, 1.1 V maximum forward voltage, and 5 µA reverse leakage current. All are ROHS3 compliant with MSL rating 1 (Unlimited). The ABS2U is available in Tape & Reel packaging with 1147 units in stock. The DF02S-E3/77 is available in Cut Tape & Digi-Reel packaging with 30300 units in stock. The DF02SA-E3/77 is available in Tape & Reel packaging with 2100 units in stock.
Alternative Recommendations: DB103S, DBLS103G, DBLS103GHRDG, DF02S1
The DB103S (Rectron USA) provides superior performance with 1.0 V maximum forward voltage and 1 µA reverse leakage current, both lower than the ABS2-G specification. The DBLS103G and DBLS103GHRDG (Taiwan Semiconductor Corporation) offer improved reverse leakage performance at 2 µA. The DBLS103GHRDG carries AEC-Q101 automotive qualification. The DF02S1 (Fairchild Semiconductor) provides 3 µA reverse leakage current. All alternative parts maintain the required 200 V peak reverse voltage and 1 A average rectified current ratings.

The REACH status varies across manufacturers: ABS2U and DF02S-E3/77 and DF02SA-E3/77 are REACH Unaffected or REACH Affected; DBLS103G and DBLS103GHRDG are REACH Unaffected.
Frequently Asked Questions (FAQ)
Q: Can the ABS2-HF directly replace the ABS2-G without circuit modification?
A: Yes. The ABS2-HF maintains identical electrical specifications across all critical parameters: 200 V peak reverse voltage, 1 A average rectified current, 1.1 V maximum forward voltage at 1 A, and 5 µA reverse leakage current at 200 V. Both parts use the same 4-SMD, Gull Wing package configuration and operate across the same temperature range (-55°C to 150°C). No circuit modification is required.
Q: What is the difference between the ABS2U and DF02S-E3/77?
A: Both parts are parametric equivalents with identical electrical specifications. The primary difference is packaging and availability. The ABS2U is supplied by SMC Diode Solutions in Tape & Reel format with 1147 units in stock. The DF02S-E3/77 is supplied by Vishay in Cut Tape & Digi-Reel format with significantly higher inventory (30300 units). Both are ROHS3 compliant with MSL rating 1 (Unlimited).
Q: Why does the DB103S-HF show higher reverse leakage current (10 µA) than the ABS2-G (5 µA)?
A: The DB103S-HF is a parametric equivalent that meets the primary substitution criteria of 200 V peak reverse voltage and 1 A average rectified current. The reverse leakage current of 10 µA at 200 V remains within acceptable operating parameters for standard bridge rectifier applications. The higher leakage does not affect functional compatibility in typical rectification circuits.
Q: Is the DBLS103GHRDG suitable for automotive applications?
A: Yes. The DBLS103GHRDG carries AEC-Q101 automotive qualification and is manufactured by Taiwan Semiconductor Corporation. It maintains identical electrical specifications to the ABS2-G (200 V peak reverse voltage, 1 A average rectified current, 1.1 V maximum forward voltage) with improved reverse leakage performance at 2 µA. This part is suitable for automotive-grade reliability requirements.
Q: What is the difference between DF02S-E3/77 and DF02SA-E3/77?
A: Both parts are manufactured by Vishay and maintain identical electrical specifications. The primary difference is packaging format. The DF02S-E3/77 is supplied in Cut Tape & Digi-Reel format with 30300 units in stock. The DF02SA-E3/77 is supplied in Tape & Reel format with 2100 units in stock. Both are ROHS3 compliant with MSL rating 1 (Unlimited) and REACH Unaffected status.
Q: Can I use the DB103S (Rectron USA) as a direct replacement?
A: Yes. The DB103S meets all primary substitution criteria with 200 V peak reverse voltage and 1 A average rectified current. It provides superior performance characteristics with 1.0 V maximum forward voltage (lower than the ABS2-G specification of 1.1 V) and 1 µA reverse leakage current (lower than the ABS2-G specification of 5 µA). The 4-SMD, Gull Wing package and operating temperature range (-55°C to 150°C) are identical. This part is ROHS3 compliant with MSL rating 1 (Unlimited).
Q: What packaging options are available for substitute parts?
A: Substitute parts are available in multiple packaging formats: Tape & Reel (TR) for ABS2U, DF02SA-E3/77; Cut Tape (CT) & Digi-Reel for DF02S-E3/77; and Bulk for DF02S1. All parts maintain the same 4-SMD, Gull Wing surface mount configuration. Selection of packaging format depends on procurement volume and assembly process requirements.
Q: Are all substitute parts ROHS3 compliant?
A: Yes. All recommended substitute parts are ROHS3 compliant. This includes ABS2-HF, ABS2U, DB103S-HF, DB103S, DBLS103G, DBLS103GHRDG, DF02S-E3/77, DF02SA-E3/77, and DF02S1. All parts carry MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling.
