Substitute Part Grouping Explanation

Substitution eligibility for bridge rectifier diodes is determined by strict equivalence in the following parameters:

Critical Parameters (Must Match or Exceed):

Voltage - Peak Reverse (Max): 50 V minimum
Diode Type: Single Phase
Mounting Type: QC Terminal
Package / Case: KBPC form factor
Technology: Standard

Performance Parameters (Application-Dependent):

Current - Average Rectified (Io): Application circuit determines minimum acceptable rating
Voltage - Forward (Vf): Forward voltage drop affects thermal performance
Current - Reverse Leakage: Leakage current affects circuit efficiency

Compliance & Environmental:

Operating Temperature Range: -55°C to 150°C
RoHS Status: Compliant or equivalent certification required

The KBPC10005-G is grouped as a substitute based on matching voltage rating, diode type, mounting configuration, and package form factor. Current rating differences are application-dependent and do not preclude substitution in circuits designed for lower current requirements.

Engineering Selection Recommendations

KBPC25005T (GeneSiC Semiconductor) is the primary specification. This part is Active status, RoHS Compliant, and rated for 25 A average rectified current with 5 µA reverse leakage at 50 V.

KBPC10005-G (Comchip Technology) is a substitute option with the following considerations:

Current Rating: The KBPC10005-G is rated for 10 A average rectified current, compared to 25 A for the KBPC25005T. This part is suitable only for applications where the circuit current requirement does not exceed 10 A.
Reverse Leakage: The KBPC10005-G exhibits 10 µA reverse leakage at 50 V, compared to 5 µA for the KBPC25005T. This difference is acceptable in standard rectification applications where leakage current does not dominate circuit performance.
Compliance: Both parts are RoHS compliant. The KBPC10005-G carries ROHS3 Compliant status and REACH Unaffected designation, meeting current regulatory requirements.
Package Compatibility: Both parts use QC Terminal mounting and 4-Square KBPC package form factors, ensuring mechanical and electrical compatibility with existing PCB layouts.
Temperature Range: Both parts operate across -55°C to 150°C, supporting equivalent thermal performance in industrial applications.

Frequently Asked Questions (FAQ)

Q: Can KBPC10005-G replace KBPC25005T in all applications?

A: No. The KBPC10005-G is rated for 10 A average rectified current, while the KBPC25005T is rated for 25 A. The KBPC10005-G is suitable only for applications where circuit current does not exceed 10 A. Exceeding this rating will result in device failure.

Q: Are the packages physically identical?

A: Both parts use QC Terminal mounting and 4-Square KBPC package form factors. The KBPC25005T uses KBPC-T variant, while KBPC10005-G uses standard KBPC. Both are compatible with equivalent PCB footprints and terminal configurations.

Q: What is the significance of the reverse leakage current difference?

A: The KBPC10005-G exhibits 10 µA reverse leakage compared to 5 µA for the KBPC25005T at 50 V. In standard rectification circuits, this difference is typically negligible. Applications with stringent leakage requirements should specify the lower-leakage KBPC25005T.

Q: Do both parts meet current RoHS requirements?

A: Yes. The KBPC25005T is RoHS Compliant. The KBPC10005-G is ROHS3 Compliant and REACH Unaffected, meeting current regulatory standards for electronic components.

Q: What is the forward voltage drop difference?

A: Both parts specify 1.1 V maximum forward voltage drop. The KBPC25005T is rated at 1.1 V @ 12.5 A, while the KBPC10005-G is rated at 1.1 V @ 5 A. Forward voltage characteristics are equivalent at their respective rated currents.

Q: Can KBPC25005T replace KBPC10005-G?

A: Yes. The KBPC25005T can replace KBPC10005-G in any application. The higher current rating (25 A vs. 10 A) and lower reverse leakage (5 µA vs. 10 µA) make it suitable for all circuits where KBPC10005-G is used.
