2KBP10M Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The 2KBP10M is a single-phase bridge rectifier manufactured by onsemi, rated for 1 kV peak reverse voltage and 2 A average rectified current. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The 2KBP10M features a 4-SIP KBPM package with through-hole mounting, suitable for standard rectification applications requiring 1 kV voltage isolation.

Substitute Part Grouping Explanation

Substitution for the 2KBP10M is determined by the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

Voltage - Peak Reverse (Max): 1 kV minimum
Current - Average Rectified (Io): 2 A minimum
Diode Type: Single Phase
Mounting Type: Through Hole
Package compatibility: 4-SIP form factor

Substitution Logic:

Parts meeting all primary criteria are direct substitutes. The 2KBP10M lists VS-2KBP10 as an approved substitute, which matches all electrical specifications and maintains the same 1 kV / 2 A rating with identical package form factor.

KBP10G (Diodes Incorporated) qualifies as a substitute despite lower current rating (1.5 A vs. 2 A) because it meets the 1 kV voltage requirement and maintains through-hole 4-SIP packaging. However, the reduced current capacity limits its use to applications requiring ≤1.5 A.

KBP210G (Diotec Semiconductor) provides 1 kV / 1.2 A capability in compatible 4-SIP KBP packaging, suitable for applications with current requirements ≤1.2 A.

Lower voltage parts (VS-2KBP005, VS-2KBP02, VS-2KBP04, VS-2KBP06, VS-2KBP08) are not direct substitutes due to voltage ratings below 1 kV and are listed only for reference in voltage-derating scenarios.

Engineering Selection Recommendations

Primary Recommendation: VS-2KBP10 (Vishay)

VS-2KBP10 is the optimal substitute for 2KBP10M applications. It maintains identical electrical specifications (1 kV / 2 A), operates across a compatible temperature range (-40°C to 150°C), and holds active product status with ROHS3 compliance. The D-44 package is mechanically compatible with KBPM through-hole mounting. Inventory availability (1525 pcs) supports production requirements.

Secondary Recommendation: KBP10G (Diodes Incorporated)

KBP10G serves applications where current requirements do not exceed 1.5 A. It provides the widest operating temperature range (-65°C to 150°C), ROHS3 compliance, and active product status. The KBP package maintains 4-SIP through-hole compatibility. High inventory (11733 pcs) ensures supply continuity.

Tertiary Recommendation: KBP210G (Diotec Semiconductor)

KBP210G accommodates designs with current requirements ≤1.2 A. It maintains 1 kV voltage rating and 4-SIP KBP package compatibility. Active product status supports long-term availability, though REACH status is vendor-undefined.

Not Recommended for Direct Substitution:

VS-2KBP005, VS-2KBP02, VS-2KBP04, VS-2KBP06, and VS-2KBP08 do not meet the 1 kV voltage requirement and are unsuitable for applications designed for the 2KBP10M.

Frequently Asked Questions (FAQ)

Q: Can VS-2KBP10 directly replace 2KBP10M in existing designs?

A: Yes. VS-2KBP10 matches the 2KBP10M electrical specifications (1 kV / 2 A) and maintains through-hole 4-SIP package compatibility. No circuit modifications are required.

Q: What is the difference between KBPM and D-44 packages?

A: Both are 4-SIP through-hole packages with identical pin configurations and mechanical footprints. KBPM is the onsemi designation; D-44 is the Vishay designation. They are mechanically interchangeable.

Q: Can KBP10G be used if the application only requires 1.5 A?

A: Yes. KBP10G is rated for 1.5 A average rectified current and maintains the 1 kV voltage specification. It is suitable for applications with current requirements ≤1.5 A.

Q: What is the impact of the lower reverse leakage current in KBP10G?

A: KBP10G specifies 5 µA @ 1000 V, identical to 2KBP10M. This parameter does not differentiate these parts.

Q: Why is VS-2KBP10 preferred over KBP10G despite lower current rating?

A: VS-2KBP10 matches the full 2 A specification of 2KBP10M, eliminating current derating concerns. For applications requiring the full 2 A capacity, VS-2KBP10 is the appropriate choice.

Q: Are lower voltage alternatives (VS-2KBP02, VS-2KBP04, VS-2KBP06) acceptable?

A: No. These parts are rated below 1 kV and do not meet the electrical requirements of 2KBP10M. They are unsuitable for direct substitution.

Q: What is the operating temperature impact when switching from 2KBP10M to KBP10G?

A: 2KBP10M operates -55°C to 150°C; KBP10G operates -65°C to 150°C. KBP10G provides extended low-temperature capability. For applications within -40°C to 150°C, both parts are equivalent.
