2KBP06M-M4/51 Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The 2KBP06M-M4/51 is a single-phase bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division, rated for 600 V peak reverse voltage and 2 A average rectified current. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The bridge rectifier is designed for through-hole mounting in KBPM package configuration and operates across a temperature range of -55°C to 165°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2KBP06M-M4/51 is determined by the following critical electrical and mechanical parameters:

• Voltage - Peak Reverse (Max): 600 V minimum requirement
• Diode Type: Single Phase bridge rectifier configuration
• Mounting Type: Through Hole
• Package / Case: 4-SIP form factor compatibility
• Current - Average Rectified (Io): Minimum 2 A capability
• Voltage - Forward (Vf): Maximum 1.1 V @ rated current
• Current - Reverse Leakage: Maximum 5 µA @ 600 V
• Operating Temperature Range: Compatibility with application requirements
• RoHS Compliance: ROHS3 Compliant status

The KBP06G from Diodes Incorporated meets these substitution criteria as an active product with equivalent electrical ratings and compatible through-hole packaging.

Parameter Comparison

Engineering Selection Recommendations

The KBP06G is an active product substitute for the obsolete 2KBP06M-M4/51. Both components maintain ROHS3 compliance and identical moisture sensitivity ratings. The substitute part shares equivalent voltage ratings (600 V peak reverse) and forward voltage characteristics (1.1 V maximum). Both components feature through-hole mounting in compatible 4-SIP package configurations.

The primary design consideration is the current rating difference: the KBP06G is rated for 1.5 A average rectified current compared to the 2 A rating of the main part. Applications requiring the full 2 A capacity must evaluate whether the 1.5 A substitute meets circuit requirements. The operating temperature range of the KBP06G (-65°C to 150°C) provides extended low-temperature performance but operates to a lower maximum junction temperature than the main part (150°C versus 165°C).

Frequently Asked Questions (FAQ)

Q: Can the KBP06G directly replace the 2KBP06M-M4/51 in existing designs?

A: The KBP06G is mechanically and electrically compatible for applications requiring up to 1.5 A average rectified current. Applications designed for the full 2 A capacity of the original part require circuit evaluation to confirm the 1.5 A rating is acceptable.

Q: Are the package configurations identical between these parts?

A: Both parts use 4-SIP through-hole packages. The main part uses KBPM package designation while the substitute uses KBP designation. Both are compatible with standard through-hole PCB layouts for 4-SIP bridge rectifiers.

Q: What are the compliance differences between these parts?

A: Both the 2KBP06M-M4/51 and KBP06G maintain ROHS3 compliance, REACH unaffected status, and MSL 1 (unlimited) moisture sensitivity ratings. Compliance profiles are equivalent for regulatory purposes.

Q: How do the operating temperature ranges compare?

A: The KBP06G operates from -65°C to 150°C, providing 10°C lower minimum temperature capability than the main part (-55°C). The maximum junction temperature is 15°C lower (150°C versus 165°C). Applications operating near the upper temperature limit require verification that 150°C maximum is acceptable.

Q: What is the significance of the current rating difference?

A: The KBP06G is rated for 1.5 A average rectified current versus 2 A for the main part. This represents a 25% reduction in current capacity. Circuit designs must confirm that peak and average current demands do not exceed 1.5 A for reliable operation.
