Engineering Selection Recommendations

KBPC2508-G (Comchip Technology) is the primary direct substitute for KBPC2508T. This part maintains identical electrical specifications including 25A current rating, 800V voltage rating, and 1.1V forward voltage. Both parts share the KBPC package designation and 4-Square case style. The KBPC2508-G carries ROHS3 compliance with REACH Unaffected status, providing enhanced regulatory alignment. Inventory availability is higher at 1155 units compared to 777 units for the original part.

KBPC3508-G (Comchip Technology) serves as a substitute for applications requiring increased current capacity. This part maintains all critical voltage and thermal parameters while providing 35A average rectified current. The 4-Square KBPC package ensures mechanical compatibility. ROHS3 compliance and REACH Unaffected status are maintained. This substitute is suitable when design margins or load growth require higher current capability within the same voltage class.

GBPC5008-G (Comchip Technology) is a substitute for high-current applications requiring 50A capacity. This part maintains 800V voltage rating and identical thermal characteristics. The GBPC package designation indicates a different mechanical form factor (4-Square GBPC case) compared to the KBPC series. This substitute is applicable when current requirements exceed 35A while maintaining 800V system voltage. Packaging is supplied in Tray configuration.

All substitutes maintain active product status and comply with RoHS and environmental regulations. Selection between substitutes depends on application current requirements and packaging preferences.

Frequently Asked Questions (FAQ)

Q: Can KBPC2508-G directly replace KBPC2508T without circuit modification?

A: Yes. KBPC2508-G maintains identical electrical parameters: 800V peak reverse voltage, 25A average rectified current, 1.1V forward voltage, and -55°C to 150°C operating range. Both use QC Terminal mounting and 4-Square KBPC package configuration. No circuit modification is required.

Q: What is the difference between KBPC and GBPC package designations?

A: Both KBPC and GBPC are 4-Square case styles with QC Terminal mounting. The designation difference reflects manufacturer series classification. KBPC is the GeneSiC and Comchip standard series designation, while GBPC is an alternative Comchip series designation. Both are mechanically and electrically compatible for 800V single phase bridge rectifier applications.
