KBPC1501T Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The KBPC1501T is a single-phase bridge rectifier manufactured by GeneSiC Semiconductor, rated for 100 V peak reverse voltage and 15 A average rectified current. This component is classified as Active product status and is RoHS Compliant. Bridge rectifiers are essential in power conversion applications requiring full-wave rectification with integrated four-diode bridge configuration. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain considerations, or application-specific requirements within the allowed parameter ranges.

Substitute Part Grouping Explanation

Substitution of the KBPC1501T is determined by strict equivalence in the following critical parameters:

Mandatory Matching Parameters:

Voltage - Peak Reverse (Max): 100 V
Diode Type: Single Phase
Technology: Standard
Mounting Type: QC Terminal
Operating Temperature Range: -55°C to 150°C

Allowable Variation Parameters:

Current - Average Rectified (Io): Substitute must equal or exceed 15 A
Voltage - Forward (Vf): Substitute must not exceed 1.1 V at rated current
Current - Reverse Leakage: Substitute specifications are acceptable within standard performance ranges
Package / Case: Mechanical compatibility with QC Terminal mounting required

The GBPC5001-G qualifies as a substitute based on matching voltage rating, diode type, technology classification, mounting type, and operating temperature range. The GBPC5001-G provides higher current capacity (50 A versus 15 A), which is acceptable for applications requiring the KBPC1501T specification.

Engineering Selection Recommendations

KBPC1501T (Primary Selection)

Active product status with confirmed inventory (732 Pcs)
RoHS Compliant certification
Specified for 15 A average rectified current applications
GeneSiC Semiconductor manufacturer designation

GBPC5001-G (Substitute Selection)

Active product status with confirmed inventory (873 Pcs)
ROHS3 Compliant certification with REACH Unaffected status
Rated for 50 A average rectified current, exceeding KBPC1501T requirement
Comchip Technology manufacturer designation
Suitable for applications where higher current capacity provides design margin or where KBPC1501T availability is constrained

Both parts maintain identical voltage ratings, operating temperature ranges, and mounting configurations. Selection between these parts is determined by current requirement, manufacturer preference, and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can GBPC5001-G replace KBPC1501T in all applications?

A: The GBPC5001-G is electrically and mechanically compatible with KBPC1501T applications. The higher current rating (50 A versus 15 A) does not create incompatibility. Thermal management and PCB layout considerations remain application-specific.

Q: Are the QC Terminal packages mechanically interchangeable?

A: Both KBPC-T and GBPC packages use QC Terminal mounting. Mechanical compatibility is confirmed for standard mounting configurations. Verify PCB pad spacing and terminal positioning in your specific application.

Q: What is the difference between RoHS and ROHS3 compliance?

A: Both certifications indicate restriction of hazardous substances. ROHS3 represents the current regulatory standard. Both parts meet environmental compliance requirements.

Q: Does the higher current rating of GBPC5001-G affect forward voltage characteristics?

A: Forward voltage is specified at different current levels (1.1 V @ 7.5 A for KBPC1501T; 1.1 V @ 25 A for GBPC5001-G). Both maintain 1.1 V maximum forward voltage within their respective rated conditions.

Q: Are there inventory considerations for substitution?

A: KBPC1501T has 732 Pcs in stock; GBPC5001-G has 873 Pcs in stock. Both are available as new original components.
