RABS15MHREG Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The RABS15MHREG is a single-phase bridge rectifier diode manufactured by Taiwan Semiconductor Corporation, designed for surface mount applications. This component operates at 1 kV peak reverse voltage with 1.5 A average rectified current and is qualified to automotive standards (AEC-Q101). The part is actively produced and maintains ROHS3 compliance with unlimited moisture sensitivity rating. Alternative part numbers within the same product family are available to accommodate different packaging and inventory requirements while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution of the RABS15MHREG is determined by strict equivalence across all critical electrical parameters and mechanical specifications. The substitute parts RABS15MH and RABS15M share identical electrical characteristics with the main part: 1 kV peak reverse voltage, 1.5 A average rectified current, 1.3 V forward voltage drop at 1.5 A, and 1 µA reverse leakage current at 1000 V. All parts operate across the same temperature range (-55°C to 150°C) and utilize the same 4-SMD Gull Wing package configuration with ABS-L supplier device package designation.

The primary distinction between substitute parts lies in packaging format and automotive qualification status. RABS15MH maintains full automotive-grade designation with AEC-Q101 qualification identical to the main part. RABS15M is supplied in standard packaging without automotive grade specification. All three parts are manufactured by Taiwan Semiconductor Corporation and maintain ROHS3 compliance with unlimited moisture sensitivity rating.

Substitution is valid when the following parameters are matched:

• Voltage - Peak Reverse (Max): 1 kV
• Current - Average Rectified (Io): 1.5 A
• Voltage - Forward (Vf) (Max) @ If: 1.3 V @ 1.5 A
• Current - Reverse Leakage @ Vr: 1 µA @ 1000 V
• Operating Temperature Range: -55°C ~ 150°C (TJ)
• Package / Case: 4-SMD, Gull Wing
• Supplier Device Package: ABS-L

Parameter Comparison

Engineering Selection Recommendations

All three parts—RABS15MHREG, RABS15MH, and RABS15M—are active products manufactured by Taiwan Semiconductor Corporation with identical electrical performance and mechanical compatibility. Selection between these parts depends on application requirements and compliance mandates.

For automotive applications requiring AEC-Q101 qualification, both RABS15MHREG and RABS15MH are suitable selections. RABS15MH offers higher inventory availability (5647 pieces) compared to RABS15MHREG (713 pieces) while maintaining identical automotive-grade specifications and packaging format.

For non-automotive applications where automotive qualification is not required, RABS15M provides equivalent electrical performance and mechanical compatibility. This part is supplied in standard Tape & Reel packaging and maintains the highest inventory level (2144 pieces).

All parts maintain ROHS3 compliance and unlimited moisture sensitivity rating, ensuring compatibility with standard surface mount assembly processes and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can RABS15M be used as a direct substitute for RABS15MHREG in automotive applications?

A: RABS15M shares identical electrical parameters and mechanical specifications with RABS15MHREG. However, RABS15M does not carry automotive-grade designation or AEC-Q101 qualification. Use of RABS15M in automotive applications depends on specific design requirements and qualification mandates for the end application.

Q: What is the difference between RABS15MHREG and RABS15MH?

A: Both parts are automotive-grade with AEC-Q101 qualification and identical electrical specifications. The primary difference is packaging format: RABS15MHREG is supplied in standard packaging, while RABS15MH is supplied in Tape & Reel format. Electrical performance and mechanical compatibility are equivalent.

Q: Are all three parts compatible with the same PCB footprint?

A: Yes. All three parts utilize the 4-SMD Gull Wing package configuration with ABS-L supplier device package designation, ensuring identical PCB footprint compatibility.

Q: Do all substitute parts maintain the same operating temperature range?

A: Yes. RABS15MHREG, RABS15MH, and RABS15M all operate across the identical temperature range of -55°C to 150°C (TJ).

Q: Are there any differences in electrical performance between the three parts?

A: No. All three parts share identical electrical specifications: 1 kV peak reverse voltage, 1.5 A average rectified current, 1.3 V forward voltage drop at 1.5 A, and 1 µA reverse leakage current at 1000 V.

Q: What is the moisture sensitivity level for all three parts?

A: All three parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling.

Q: Are all parts ROHS3 compliant?

A: Yes. RABS15MHREG, RABS15MH, and RABS15M are all ROHS3 compliant.
