KBP02M Bridge Rectifier Single Phase 200V 1.5A Equivalent & Substitute Parts

Part Overview

The KBP02M is a single-phase bridge rectifier manufactured by onsemi, rated for 200V peak reverse voltage and 1.5A average rectified current in a 4-SIP KBPM through-hole package. This part is classified as obsolete. Due to its obsolete status, equivalent and substitute parts from active manufacturers are necessary for new designs and ongoing production requirements. Substitute parts maintain the core electrical specifications while offering improved availability and active product support.

Substitute Part Grouping Explanation

Substitute parts for the KBP02M are grouped based on electrical parameter compatibility. The primary substitution criteria are:

Voltage - Peak Reverse (Max): 200 V minimum
Current - Average Rectified (Io): 1.5 A minimum
Diode Type: Single Phase
Technology: Standard
Mounting Type: Through Hole

Parts are classified into two categories:

Category 1: Direct Electrical Equivalents (200V, 1.5A–2A) These parts maintain the 200V voltage rating and meet or exceed the 1.5A current requirement. Package variations exist but all are through-hole mounted.

Category 2: Higher Voltage Ratings (50V–1kV) These parts are listed in the original part's substitute field but operate at different voltage ratings. They are suitable only when the application voltage requirement differs from 200V.

Engineering Selection Recommendations

For 200V Applications (Direct Replacement):

KBP02G (Diodes Incorporated) is the primary substitute for KBP02M. It maintains the 200V voltage rating and 1.5A current specification with active product status and RoHS3 compliance. The operating temperature range is -65°C to 150°C, which covers the lower end of the KBP02M range (-55°C to 165°C).

KBP202G (SMC Diode Solutions) provides a 200V rated alternative with increased current capacity (2A) and active product status. REACH compliance status is affected; verify regulatory requirements for your application.

VS-2KBP02 (Vishay) offers 200V rating with 2A capacity, active status, and RoHS3 compliance. Operating temperature range is -40°C to 150°C. Package is 4-SIP D-44 instead of KBPM.

For Non-200V Applications:

VS-2KBP005, VS-2KBP06, and VS-2KBP10 are suitable only when the application requires 50V, 600V, or 1kV ratings respectively. These parts are not direct replacements for 200V circuits.

All recommended substitutes feature through-hole mounting and single-phase bridge rectifier topology consistent with the KBP02M.

Frequently Asked Questions (FAQ)

Q: Can KBP02G directly replace KBP02M in a 200V circuit?

A: Yes. KBP02G maintains the 200V peak reverse voltage and 1.5A average rectified current specifications. Package footprint is 4-SIP KBP, which is compatible with KBPM through-hole mounting. Verify PCB layout compatibility before substitution.

Q: What is the difference between KBP02G and KBP202G?

A: Both are rated for 200V. KBP202G has higher current capacity (2A vs 1.5A) and uses a 4-ESIP package instead of 4-SIP. KBP202G is suitable if higher current margin is required. REACH compliance status differs between the two parts.

Q: Why are VS-2KBP005, VS-2KBP06, and VS-2KBP10 listed as substitutes?

A: These parts are listed in the KBP02M original substitute field but operate at different voltage ratings (50V, 600V, and 1kV respectively). They are not direct replacements for 200V applications. Use these only if your circuit requires a different voltage rating.

Q: What is the impact of forward voltage differences between KBP02M and substitute parts?

A: KBP02M specifies 1 V @ 1 A forward voltage. KBP02G and KBP202G specify 1.1 V @ 1.5 A and 1.1 V @ 2 A respectively. This 0.1V difference is within typical bridge rectifier tolerance and does not affect circuit functionality in standard applications. VS-2KBP series parts maintain 1 V @ 1 A specification.

Q: Are all substitute parts RoHS compliant?

A: KBP02G and VS-2KBP series parts are RoHS3 compliant. KBP202G is RoHS3 compliant. Verify compliance requirements for your specific application and region.

Q: What operating temperature range should I select?

A: KBP02M operates from -55°C to 165°C. KBP02G operates from -65°C to 150°C, providing lower temperature coverage but reduced upper temperature limit. VS-2KBP series parts operate from -40°C to 150°C. Select based on your application's thermal requirements.
