KBP06M-E4/45 Equivalent & Substitute Parts

Part Overview

The KBP06M-E4/45 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 identification of equivalent and substitute parts essential for ongoing system maintenance and new design implementations. The through-hole KBPM package configuration requires compatible alternatives that maintain electrical and mechanical compatibility with existing circuit layouts.

Substitute Part Grouping Explanation

Substitution eligibility for the KBP06M-E4/45 is determined by the following critical parameters:

Voltage - Peak Reverse (Max): Must equal or exceed 600 V
Current - Average Rectified (Io): Must support minimum 1.5 A operation
Diode Type: Must be Single Phase bridge rectifier
Mounting Type: Must be Through Hole
Package / Case: Must be compatible 4-SIP configuration (KBPM or KBP variants)
Voltage - Forward (Vf): Must not exceed 1.1 V at rated current
Current - Reverse Leakage: Must not exceed 5 µA @ 600 V

The identified substitute parts KBP06G and KBP206G meet these electrical and mechanical criteria, enabling direct functional replacement in applications requiring 600 V, 1.5 A single-phase bridge rectification.

Engineering Selection Recommendations

KBP06G (Diodes Incorporated) is the primary recommended substitute. This part maintains identical electrical specifications (600 V, 1.5 A) and is currently in active production status with ROHS3 compliance certification. The KBP06G offers an extended lower operating temperature limit (-65°C versus -55°C), providing enhanced performance margin in cold-temperature applications. Packaging compatibility with the 4-SIP KBP configuration ensures mechanical fit in existing through-hole layouts.

KBP206G (Diotec Semiconductor) is an alternative substitute suitable for applications where the 1.2 A average rectified current rating is sufficient. This part maintains the 600 V voltage specification and identical forward voltage characteristics. However, the reduced current rating and non-applicable RoHS status should be evaluated against specific application requirements and regulatory compliance mandates.

Both substitute parts are actively manufactured and available in production quantities, eliminating supply chain constraints associated with the obsolete KBP06M-E4/45.

Frequently Asked Questions (FAQ)

Q: Can KBP06G directly replace KBP06M-E4/45 in existing designs?

A: Yes. KBP06G meets all critical electrical parameters (600 V, 1.5 A) and uses compatible 4-SIP through-hole packaging. Physical pin configuration and electrical performance are equivalent for direct substitution.

Q: What is the difference between KBP06G and KBP206G?

A: The primary difference is average rectified current rating: KBP06G supports 1.5 A while KBP206G supports 1.2 A. Both maintain 600 V voltage specification and identical forward voltage characteristics. KBP206G has non-applicable RoHS status, whereas KBP06G is ROHS3 compliant.

Q: Are there temperature range differences between the substitutes?

A: Yes. KBP06G operates from -65°C to 150°C, providing a 10°C lower minimum temperature limit compared to the original KBP06M-E4/45 (-55°C to 150°C). KBP206G operates from -50°C to 150°C. Application-specific temperature requirements should determine the appropriate selection.

Q: Is the KBPM package identical to the KBP package?

A: Both are 4-SIP through-hole configurations with compatible pin layouts. The KBPM and KBP designations represent manufacturer-specific package naming conventions. Physical dimensions and electrical connectivity are equivalent for circuit board integration.

Q: Which substitute should be selected for new designs?

A: KBP06G is recommended for new designs due to active production status, ROHS3 compliance, and full electrical specification match (600 V, 1.5 A). This ensures long-term supply availability and regulatory compliance alignment.
