2KBP01M Bridge Rectifier Single Phase 100V 2A Equivalent & Substitute Parts

Part Overview

The 2KBP01M is a single-phase bridge rectifier manufactured by onsemi, rated for 100 V peak reverse voltage and 2 A average rectified current in a 4-SIP KBPM through-hole package. This component is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production support. Bridge rectifiers in this voltage and current class are used in power supply circuits, battery chargers, and AC-to-DC conversion applications where single-phase rectification is required.

Substitute Part Grouping Explanation

Substitution for the 2KBP01M is determined by the following critical parameters:

Voltage Rating: Peak reverse voltage must be 100 V or higher to maintain circuit protection margins
Current Rating: Average rectified current must be 2 A or higher to handle design load requirements
Diode Type: Single-phase bridge rectifier configuration
Technology: Standard rectifier technology
Mounting Type: Through-hole package for PCB compatibility
Forward Voltage: Maximum forward voltage drop at rated current must not exceed design specifications

Parts are grouped into two categories:

Category A - Direct Equivalents (100 V, 2 A): Parts with matching voltage and current ratings, suitable for direct replacement with minimal circuit impact.

Category B - Higher Voltage Alternatives (200 V and above, 2 A): Parts with higher voltage ratings that provide additional design margin but require verification of circuit requirements. These are suitable only when higher voltage tolerance is acceptable.

Category C - Lower Current Alternative (100 V, 1.5 A): Parts with reduced current rating that may be suitable only for applications with lower current demands than the original design specification.

Engineering Selection Recommendations

Primary Substitute - KBP201G (SMC Diode Solutions)

KBP201G is the closest functional equivalent to 2KBP01M. It maintains the 100 V / 2 A rating with identical forward voltage characteristics and reverse leakage specifications. The part is active and ROHS3 compliant. Package differences (4-ESIP vs. KBPM) require PCB layout verification for pin compatibility, but electrical performance is equivalent.

Secondary Substitute - KBP01G (Diodes Incorporated)

KBP01G provides 100 V rating with reduced current capacity (1.5 A vs. 2 A). This part is suitable only for applications where the actual load current does not exceed 1.5 A. The part is active and ROHS3 compliant with extended operating temperature range (-65°C to 150°C). Package compatibility with 4-SIP KBP requires verification.

Higher Voltage Alternatives - VS-2KBP Series (Vishay)

The VS-2KBP02, VS-2KBP04, VS-2KBP06, VS-2KBP08, and VS-2KBP10 parts maintain 2 A current rating with voltage ratings of 200 V, 400 V, 600 V, 800 V, and 1 kV respectively. These parts are suitable for applications where higher voltage margin is required or where the circuit operates at higher AC input voltages. All are active and ROHS3 compliant. Package is 4-SIP D-44, requiring PCB layout verification.

Not Recommended - VS-2KBP005

VS-2KBP005 has a 50 V peak reverse voltage rating, which is below the 100 V specification of the original part. This part does not meet the voltage requirement and is not suitable as a substitute.

Frequently Asked Questions (FAQ)

Q: Can KBP01G replace 2KBP01M directly?

A: KBP01G is electrically compatible at 100 V but has a reduced current rating of 1.5 A versus 2 A. Direct replacement is possible only if the circuit load current does not exceed 1.5 A. Package differences (4-SIP KBP vs. KBPM) require PCB layout verification.

Q: What is the difference between the KBPM and KBP packages?

A: Both are 4-SIP through-hole packages. Physical dimensions and pin spacing may differ. PCB footprint verification is required before substitution.

Q: Can I use a higher voltage rated part like VS-2KBP06 (600 V) instead of 2KBP01M (100 V)?

A: Yes, higher voltage rated parts are electrically compatible and provide additional design margin. However, the circuit must be designed to accommodate the higher voltage rating. Forward voltage characteristics differ slightly (1 V vs. 1.1 V), which may affect power dissipation calculations. Verify that the higher voltage rating does not introduce unintended circuit behavior.

Q: Are all substitute parts RoHS compliant?

A: KBP201G and KBP01G are ROHS3 compliant. All Vishay VS-2KBP series parts are ROHS3 compliant. The original 2KBP01M does not specify RoHS status.

Q: What is the temperature operating range difference between 2KBP01M and KBP01G?

A: 2KBP01M operates from -55°C to 150°C, while KBP01G operates from -65°C to 150°C. KBP01G has a lower minimum temperature rating, providing wider temperature coverage.

Q: Can I use VS-2KBP02 (200 V) in a 100 V circuit?

A: Yes. The 200 V rating indicates the maximum voltage the part can withstand. In a 100 V circuit, the part operates well within its rating and provides additional safety margin. Forward voltage is lower (1 V vs. 1.1 V), which may reduce power dissipation slightly.

Q: What inventory status should I consider for production?

A: KBP201G has 1270 pcs in stock, KBP01G has 778 pcs, and Vishay VS-2KBP series parts have inventory ranging from 917 to 2553 pcs. All substitute parts are listed as active products with current availability.
