2KBP06M Bridge Rectifier Single Phase 600V 2A Equivalent & Substitute Parts

Part Overview

The 2KBP06M is a single-phase bridge rectifier manufactured by onsemi, rated for 600 V peak reverse voltage and 2 A average rectified current in a 4-SIP KBPM through-hole package. The part is currently obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. Substitute parts must maintain electrical compatibility within the specified voltage and current ratings while accommodating package and thermal operating range variations.

Substitute Part Grouping Explanation

Substitution eligibility for the 2KBP06M is determined by the following critical parameters:

Voltage - Peak Reverse (Max): Must be ≥ 600 V to maintain voltage margin
Current - Average Rectified (Io): Must be ≥ 2 A to support load requirements
Diode Type: Must be Single Phase bridge rectifier
Mounting Type: Must be Through Hole for PCB compatibility
Package / Case: Physical form factor (4-SIP variants acceptable with mechanical verification)

Substitute parts are grouped into two categories:

Category A - Direct Electrical Equivalents (600 V, 2 A): Parts meeting or exceeding the 2KBP06M electrical specifications with compatible through-hole packaging.

Category B - Voltage-Reduced Alternatives: Parts with lower voltage ratings (50 V, 200 V, 400 V, 800 V, 1 kV) that are electrically incompatible with the 600 V requirement and are listed for reference only.

Engineering Selection Recommendations

Primary Substitute: VS-2KBP06

The VS-2KBP06 from Vishay General Semiconductor - Diodes Division is the direct electrical equivalent, matching the 600 V and 2 A specifications of the 2KBP06M. This part is active in production and carries RoHS3 compliance. The D-44 package is mechanically compatible with through-hole PCB layouts. Operating temperature range (-40°C ~ 150°C) is narrower than the original (-55°C ~ 150°C), requiring verification for applications requiring sub-zero operation below -40°C.

Secondary Substitute: KBP06G

The KBP06G from Diodes Incorporated maintains 600 V voltage rating with active product status and RoHS3 compliance. Current rating is reduced to 1.5 A, making this suitable only for applications with maximum load current ≤ 1.5 A. Operating temperature range extends to -65°C, providing superior low-temperature performance.

Not Recommended: KBP206G, VS-2KBP02, VS-2KBP04, VS-2KBP005, VS-2KBP08, VS-2KBP10

These parts do not meet the 600 V / 2 A electrical specification of the 2KBP06M. KBP206G and VS-2KBP02, VS-2KBP04 have insufficient voltage ratings. VS-2KBP005 has insufficient voltage rating. VS-2KBP08 and VS-2KBP10 exceed the voltage requirement, introducing unnecessary cost and thermal considerations for applications designed for 600 V operation.

Frequently Asked Questions (FAQ)

Q: Can KBP06G replace 2KBP06M in all applications?

A: KBP06G is suitable only for applications where maximum average rectified current does not exceed 1.5 A. The 2KBP06M is rated for 2 A; applications requiring the full 2 A rating must use VS-2KBP06 or equivalent 2 A parts.

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

A: Both are 4-SIP through-hole packages. KBPM is the onsemi designation; KBP and D-44 are equivalent form factors used by other manufacturers. Physical pin spacing and lead geometry are compatible for standard PCB layouts, though mechanical verification is recommended for high-density designs.

Q: Why is the operating temperature range narrower for VS-2KBP06 compared to 2KBP06M?

A: The 2KBP06M operates from -55°C to 150°C, while VS-2KBP06 operates from -40°C to 150°C. Applications requiring operation below -40°C must retain the original 2KBP06M or select KBP06G (-65°C minimum). For standard industrial applications (≥ -40°C), VS-2KBP06 is fully qualified.

Q: Are there compliance differences between substitute parts?

A: VS-2KBP06 and KBP06G are RoHS3 compliant. The 2KBP06M is obsolete and compliance status is not current. All recommended substitutes carry REACH Unaffected or equivalent environmental compliance suitable for EU and international markets.

Q: Can higher voltage-rated parts (VS-2KBP08, VS-2KBP10) be used as substitutes?

A: Higher voltage ratings do not provide functional equivalence for 600 V applications. These parts introduce unnecessary cost and may exhibit different thermal characteristics. Use only parts rated for 600 V or higher with equivalent current capacity.
