KBPC2501T Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The KBPC2501T is a single-phase bridge rectifier manufactured by GeneSiC Semiconductor, rated for 100 V peak reverse voltage and 25 A average rectified current. This component is classified as Active product status with full RoHS compliance and unlimited moisture sensitivity level (MSL 1). Bridge rectifiers of this specification are used in AC-to-DC conversion applications requiring moderate voltage and current ratings. Substitute parts may be required due to inventory constraints, application-specific voltage or current demands, or manufacturer availability.

Substitute Part Grouping Explanation

Substitution of the KBPC2501T is determined by the following electrical and mechanical parameters:

Primary Substitution Criteria:

Diode Type: Single Phase (all substitutes must maintain this classification)
Mounting Type: QC Terminal (mechanical compatibility requirement)
Package / Case: 4-Square configuration (physical form factor)
Technology: Standard (process node compatibility)
Operating Temperature Range: -55°C to 150°C (thermal envelope)

Voltage and Current Compatibility: Substitute parts may differ in peak reverse voltage (Vr) and average rectified current (Io) ratings. A substitute is valid when:

Peak reverse voltage rating is equal to or greater than the application requirement
Average rectified current rating is equal to or greater than the application requirement
Forward voltage drop and reverse leakage characteristics remain within acceptable system tolerances

Compliance Requirements: All substitute parts must maintain RoHS compliance status and MSL 1 rating to ensure compatibility with standard manufacturing and storage conditions.

Engineering Selection Recommendations

GBPC2508T Substitution: The GBPC2508T maintains identical current rating (25 A) and forward voltage characteristics (1.1 V @ 12.5 A) as the KBPC2501T. The primary difference is elevated peak reverse voltage rating (800 V versus 100 V). This part is suitable for applications where higher voltage margin is required or where 100 V rated components are unavailable. Both parts carry ROHS3 compliance and MSL 1 rating. The GBPC2508T is manufactured by GeneSiC Semiconductor, maintaining consistency with the original part manufacturer.

GBPC5001-G Substitution: The GBPC5001-G is manufactured by Comchip Technology and provides doubled average rectified current capacity (50 A versus 25 A) while maintaining the same 100 V peak reverse voltage rating. Forward voltage is specified at higher current (1.1 V @ 25 A). Reverse leakage is slightly elevated (10 µA @ 100 V versus 5 µA @ 100 V). This part is suitable for applications requiring higher current capacity at the same voltage rating. ROHS3 compliance and MSL 1 rating are maintained.

All substitute parts maintain single-phase bridge rectifier topology, QC terminal mounting, 4-square package configuration, standard technology classification, and -55°C to 150°C operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can GBPC2508T replace KBPC2501T in a 100 V application?

A: Yes. The GBPC2508T is rated for 800 V peak reverse voltage, which exceeds the 100 V requirement. Current rating (25 A) and forward voltage characteristics (1.1 V @ 12.5 A) are identical. The higher voltage rating provides additional design margin without affecting circuit performance at 100 V operation.

Q: What is the difference between KBPC2501T and GBPC5001-G?

A: Both parts are rated for 100 V peak reverse voltage and share identical forward voltage drop (1.1 V). The GBPC5001-G provides 50 A average rectified current capacity compared to 25 A for the KBPC2501T. Reverse leakage current is 10 µA for GBPC5001-G versus 5 µA for KBPC2501T. Selection depends on application current requirements.

Q: Are all substitute parts mechanically compatible?

A: All listed substitutes use QC terminal mounting and 4-square package configuration, ensuring mechanical compatibility. Physical dimensions and terminal spacing conform to standard bridge rectifier form factors.

Q: Do substitute parts maintain RoHS compliance?

A: Yes. Both GBPC2508T and GBPC5001-G carry ROHS3 compliance certification. All parts maintain MSL 1 (unlimited) moisture sensitivity level, suitable for standard manufacturing and storage environments.

Q: Which substitute should be selected for higher voltage applications?

A: The GBPC2508T, rated for 800 V peak reverse voltage, is suitable for applications exceeding 100 V requirements. The KBPC2501T and GBPC5001-G are both limited to 100 V peak reverse voltage and are not suitable for higher voltage applications.

Q: Can GBPC5001-G be used in applications designed for 25 A operation?

A: Yes. The GBPC5001-G is rated for 50 A average rectified current, which exceeds 25 A requirements. The part will operate within specification in 25 A applications. No circuit modification is required.
