KBP154G C2G Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The KBP154G C2G is a single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation, rated for 400 V peak reverse voltage and 1.5 A average rectified current. This component is classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing design support and procurement requirements. Bridge rectifiers in this specification class are used in AC-to-DC conversion applications requiring standard-technology rectification at moderate voltage and current levels.

Engineering Selection Recommendations

The KBP04G is a direct functional equivalent to the KBP154G C2G for all applications requiring single-phase bridge rectification at 400 V and 1.5 A specifications. Selection of the KBP04G is supported by the following factors:

• Electrical Equivalence: Identical voltage and current ratings with matching forward voltage characteristics ensure drop-in compatibility in existing circuit designs.
• Enhanced Leakage Performance: The KBP04G exhibits lower reverse leakage current (5 µA versus 10 µA at 400 V), providing improved performance in applications sensitive to leakage characteristics.
• Extended Temperature Range: The KBP04G operates across -65°C to 150°C, extending the lower temperature limit by 10°C compared to the main part, providing broader environmental compatibility.
• Active Production Status: The KBP04G is in active production, ensuring sustained availability and supply chain continuity.
• Regulatory Compliance: Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for new designs and replacements.
• Package Compatibility: Identical 4-SIP KBP through-hole packaging enables direct board-level substitution without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the KBP04G be used as a direct replacement for the KBP154G C2G in existing designs?

A: Yes. The KBP04G meets all electrical and mechanical specifications of the KBP154G C2G. Both components share identical voltage ratings (400 V), current ratings (1.5 A), forward voltage characteristics (1.1 V @ 1.5 A), and package configuration (4-SIP KBP through-hole). Direct board-level substitution is supported without circuit modifications.

Q: What are the key differences between these two parts?

A: The primary differences are manufacturer (Taiwan Semiconductor Corporation versus Diodes Incorporated), product status (obsolete versus active), reverse leakage current (10 µA versus 5 µA at 400 V), and operating temperature range (-55°C to 150°C versus -65°C to 150°C). The KBP04G provides lower leakage and extended low-temperature operation.

Q: Are there any compliance or certification differences?

A: No. Both the KBP154G C2G and KBP04G maintain identical compliance status: ROHS3 compliant, REACH unaffected, MSL 1 (unlimited), and EAR99 export classification. Both components share the same HTSUS code (8541.10.0080).

Q: Does the KBP04G require any circuit design changes?

A: No circuit design changes are required. The KBP04G is electrically and mechanically equivalent to the KBP154G C2G across all specified parameters. The identical package type and electrical characteristics support direct substitution.

Q: What is the significance of the lower reverse leakage current in the KBP04G?

A: The KBP04G exhibits 5 µA reverse leakage at 400 V compared to 10 µA for the KBP154G C2G. Lower leakage current reduces standby power dissipation and improves performance in applications where leakage-induced errors or power consumption are design constraints.

Q: Is the extended temperature range of the KBP04G (-65°C minimum) significant for my application?

A: The extended lower temperature limit of -65°C (versus -55°C for the main part) provides additional margin for applications operating in cold environments. If your design operates above -55°C, this difference is not operationally significant. If cold-temperature operation is required, the KBP04G provides enhanced capability.
