KBPC5004T Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The KBPC5004T is a single-phase bridge rectifier manufactured by GeneSiC Semiconductor, designed for 400 V peak reverse voltage applications with 50 A average rectified current capacity. This component operates across the temperature range of -55°C to 150°C and features QC terminal mounting in a 4-Square KBPC package configuration. The part maintains Active product status and holds RoHS Compliant certification.

Substitute parts are identified when equivalent electrical performance can be achieved within the specified parameter tolerances of the application circuit, particularly when the original part becomes unavailable or when alternative sourcing is required for procurement optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KBPC5004T is determined by strict alignment with the following critical parameters:

Mandatory Matching Parameters:

• Voltage - Peak Reverse (Max): 400 V
• 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

Current Capacity Consideration: The KBPC5004T operates at 50 A average rectified current. Substitute parts identified in this reference maintain the same voltage and package specifications but may operate at different current ratings. Selection of a substitute part must account for the application's actual current requirements.

Identified Substitute Parts:

• KBPC1004-G (Comchip Technology): 10 A rated current
• KBPC2504-G (Comchip Technology): 25 A rated current

Both substitute parts maintain the 400 V peak reverse voltage, single-phase configuration, standard technology, QC terminal mounting, 4-Square KBPC package, and -55°C to 150°C operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

KBPC5004T Primary Application: The KBPC5004T is specified for applications requiring 50 A average rectified current at 400 V peak reverse voltage. This part is Active in product status and maintains RoHS Compliant certification with MSL Level 1 (Unlimited moisture sensitivity).

KBPC1004-G Substitution Scope: The KBPC1004-G is suitable only for applications where the circuit current requirement does not exceed 10 A average rectified current. This part is Active in product status and holds ROHS3 Compliant certification with REACH Unaffected status. The 10 A current rating represents a significant derating from the KBPC5004T specification and is applicable only to lower-power circuit designs.

KBPC2504-G Substitution Scope: The KBPC2504-G is suitable for applications where the circuit current requirement does not exceed 25 A average rectified current. This part is Active in product status and holds ROHS3 Compliant certification with REACH Unaffected status. The 25 A current rating provides partial coverage of the KBPC5004T specification range and is applicable to mid-range power circuit designs.

Compliance Considerations: All three parts maintain equivalent RoHS compliance status (RoHS Compliant / ROHS3 Compliant), MSL Level 1 rating, and ECCN EAR99 classification. The KBPC1004-G and KBPC2504-G include REACH Unaffected status documentation.

Frequently Asked Questions (FAQ)

Q: Can KBPC1004-G or KBPC2504-G directly replace KBPC5004T in a 50 A application?

A: No. The KBPC1004-G is rated for maximum 10 A average rectified current, and the KBPC2504-G is rated for maximum 25 A average rectified current. Direct substitution in a 50 A application would result in component overstress and failure. Substitute parts are applicable only when the actual circuit current requirement is within their respective ratings.

Q: Are the package dimensions identical between KBPC5004T and the substitute parts?

A: All three parts use the 4-Square KBPC package configuration with QC terminal mounting. The KBPC5004T specifies package designation as "4-Square, KBPC-T" while the substitute parts specify "4-Square, KBPC." Physical compatibility for PCB mounting and thermal management should be verified for the specific application.

Q: What is the difference in reverse leakage current between these parts?

A: The KBPC5004T specifies 5 µA maximum reverse leakage at 400 V, while both KBPC1004-G and KBPC2504-G specify 10 µA maximum reverse leakage at 400 V. This difference may be significant in high-impedance or precision rectification circuits.

Q: Do all three parts meet the same temperature operating range?

A: Yes. All three parts operate across the identical temperature range of -55°C to 150°C (TJ). Thermal management and derating curves should be applied according to the specific application environment.

Q: What is the significance of the forward voltage specification differences?

A: Forward voltage is specified at different current levels: KBPC5004T at 1.1 V @ 25 A, KBPC1004-G at 1.1 V @ 5 A, and KBPC2504-G at 1.1 V @ 12.5 A. These specifications reflect the maximum forward voltage at each part's respective current rating. Forward voltage characteristics should be evaluated for power dissipation calculations in the target application.

Q: Are there any compliance or certification differences between these parts?

A: The KBPC5004T holds RoHS Compliant certification. The KBPC1004-G and KBPC2504-G hold ROHS3 Compliant certification and include REACH Unaffected status. All parts share identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications. Compliance documentation should be reviewed for the specific regulatory requirements of the end application.
