KBPC2504T Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The KBPC2504T is a single-phase bridge rectifier manufactured by GeneSiC Semiconductor, designed for standard rectification applications requiring 400 V peak reverse voltage and 25 A average rectified current. The component features QC terminal mounting and operates across the industrial temperature range of -55°C to 150°C. This part maintains active product status with RoHS compliance and unlimited moisture sensitivity rating.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained within the specified parameter tolerances for single-phase bridge rectifier applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KBPC2504T is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Criteria:

• Voltage - Peak Reverse (Max): 400 V
• Current - Average Rectified (Io): 25 A
• Diode Type: Single Phase
• Technology: Standard
• Mounting Type: QC Terminal
• Package / Case: 4-Square, KBPC configuration
• Operating Temperature Range: -55°C to 150°C minimum

Acceptable Variation Parameters:

• Voltage - Forward (Vf) (Max) @ If: Within specification limits
• Current - Reverse Leakage @ Vr: Within specification limits
• RoHS Status: Compliant variants acceptable
• Moisture Sensitivity Level: MSL 1 (Unlimited)

Parts that deviate from mandatory equivalence criteria are not suitable substitutes. The KBPC1004-G does not meet current rating requirements and is excluded from direct substitution. The KBPC2504-G meets all mandatory equivalence criteria and qualifies as a substitute.

Parameter Comparison

Engineering Selection Recommendations

KBPC2504-G (Comchip Technology) qualifies as a direct substitute for KBPC2504T based on electrical and mechanical parameter equivalence. Both components maintain identical voltage and current ratings, operating temperature range, and mounting configuration. The KBPC2504-G carries ROHS3 compliance with REACH Unaffected status, meeting current regulatory requirements. The reverse leakage current specification of 10 µA at 400 V for the KBPC2504-G remains within acceptable operational limits for standard bridge rectifier applications.

KBPC1004-G (Comchip Technology) is not suitable as a substitute for KBPC2504T. The KBPC1004-G is rated for 10 A average rectified current, which does not meet the 25 A requirement of the KBPC2504T. Current rating mismatch disqualifies this part from substitution consideration.

Component selection should be based on circuit current requirements, voltage specifications, and thermal operating conditions. Both the original KBPC2504T and qualified substitute KBPC2504-G maintain identical electrical performance within the specified parameter ranges.

Frequently Asked Questions (FAQ)

Q: Can KBPC1004-G replace KBPC2504T in my application?

A: No. The KBPC1004-G is rated for 10 A average rectified current, while KBPC2504T requires 25 A. Current rating is a mandatory equivalence criterion. Using an undersized component will result in thermal stress and potential failure.

Q: What is the difference between KBPC2504T and KBPC2504-G?

A: Both components share identical electrical ratings: 400 V peak reverse voltage, 25 A average rectified current, 1.1 V forward voltage at 12.5 A, and -55°C to 150°C operating temperature. The primary difference is manufacturer (GeneSiC vs. Comchip) and reverse leakage current specification (5 µA vs. 10 µA at 400 V). Both maintain QC terminal mounting and 4-Square package configuration.

Q: Are there any compliance differences between KBPC2504T and KBPC2504-G?

A: KBPC2504T carries RoHS compliance. KBPC2504-G carries ROHS3 compliance with REACH Unaffected status. Both components have unlimited moisture sensitivity rating (MSL 1) and EAR99 export classification.

Q: Can I use KBPC2504-G in high-temperature applications?

A: Yes. KBPC2504-G maintains the same operating temperature range as KBPC2504T: -55°C to 150°C junction temperature. Thermal performance is equivalent across the specified range.

Q: What mounting compatibility exists between substitute parts?

A: Both KBPC2504T and KBPC2504-G use QC terminal mounting with 4-Square package configuration. Physical mounting is compatible. Verify PCB footprint design accommodates the specific package variant before installation.

Q: Is reverse leakage current difference significant between KBPC2504T and KBPC2504-G?

A: The reverse leakage current specification differs (5 µA vs. 10 µA at 400 V). Both values remain within acceptable limits for standard bridge rectifier applications. Selection should be based on specific circuit leakage requirements and thermal design margins.
