KBP06M-E4/51 Equivalent & Substitute Parts

Part Overview

The KBP06M-E4/51 is a single-phase bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division, rated for 600 V peak reverse voltage and 1.5 A average rectified current. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The through-hole KBPM package configuration requires direct mechanical and electrical compatibility for successful substitution.

Engineering Selection Recommendations

KBP06G (Diodes Incorporated) is the primary substitute for KBP06M-E4/51. This part maintains active product status, ensuring long-term availability and supply chain stability. It meets all critical electrical parameters with identical voltage and current ratings, maintains ROHS3 compliance, and provides an extended lower operating temperature limit (-65°C versus -55°C). The 4-SIP KBP package is mechanically compatible with the original KBPM footprint for through-hole applications.

KBP206G (Diotec Semiconductor) is a secondary substitute option. While it maintains the required 600 V voltage rating and through-hole mounting, the average rectified current rating of 1.2 A is below the 1.5 A requirement of the original part. This part is suitable only for applications where the actual circuit current demand does not exceed 1.2 A. RoHS compliance status is not applicable for this part.

Frequently Asked Questions (FAQ)

Q: Can KBP06G directly replace KBP06M-E4/51 without circuit modifications?

A: Yes. KBP06G meets all critical electrical specifications (600 V, 1.5 A, 5 µA leakage) and uses a compatible 4-SIP through-hole package. No circuit modifications are required for direct substitution.

Q: What is the difference between the KBPM and KBP package designations?

A: Both are 4-SIP through-hole packages configurations for single-phase bridge rectifiers. The KBP designation used by KBP06G and KBP206G is mechanically compatible with the original KBPM package for PCB mounting applications.

Q: Is KBP206G suitable as a substitute if my circuit operates at 1.5 A?

A: No. KBP206G has a maximum average rectified current rating of 1.2 A, which is insufficient for circuits requiring 1.5 A operation. Use KBP06G for this requirement.

Q: What compliance certifications should I verify for my application?

A: KBP06G maintains ROHS3 compliance matching the original part. KBP206G does not have applicable RoHS status. Verify compliance requirements for your specific end-use application before selection.

Q: Does operating temperature range affect substitution suitability?

A: Operating temperature range does not prevent substitution if your circuit operates within the specified limits of the substitute part. KBP06G provides a wider lower temperature range (-65°C) compared to the original (-55°C), offering additional design margin for low-temperature applications.
