2KBP01M/1 Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The 2KBP01M/1 is a single-phase bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division, rated for 100 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 2KBP01M/1 operates across a temperature range of -55°C to 165°C and is packaged in a 4-SIP KBPM configuration for through-hole mounting applications.

Substitute Part Grouping Explanation

Substitute parts for the 2KBP01M/1 are selected based on electrical parameter compatibility within the following criteria:

Primary Matching Parameters:

Voltage - Peak Reverse (Max): 100 V (exact match required)
Diode Type: Single Phase (exact match required)
Technology: Standard (exact match required)
Mounting Type: Through Hole (exact match required)

Secondary Compatibility Parameters:

Current - Average Rectified (Io): 2 A or higher acceptable
Voltage - Forward (Vf) (Max): Within acceptable operating margins
Current - Reverse Leakage @ Vr: Within acceptable operating margins
Operating Temperature Range: Must accommodate application requirements

The following parts meet these substitution criteria:

VS-2KBP01 (Vishay General Semiconductor - Diodes Division) — Manufacturer-recommended substitute with identical electrical ratings and through-hole D-44 package configuration
KBP01G (Diodes Incorporated) — Compatible single-phase bridge rectifier with 1.5 A rating; suitable where current requirements do not exceed 1.5 A
KBP201G (SMC Diode Solutions) — Compatible single-phase bridge rectifier with 2 A rating and 4-ESIP package; maintains electrical equivalence

Engineering Selection Recommendations

VS-2KBP01 is the primary substitute choice. This part is manufactured by the same supplier (Vishay General Semiconductor - Diodes Division), maintains identical electrical specifications for voltage and current ratings, and is actively produced. The VS-2KBP01 achieves ROHS3 compliance, addressing regulatory requirements that the obsolete 2KBP01M/1 does not meet. The D-44 package is mechanically compatible with through-hole PCB layouts designed for the original KBPM package.

KBP201G provides an alternative from SMC Diode Solutions with equivalent 2 A current rating and 100 V voltage specification. This part is actively produced and ROHS3 compliant. The 4-ESIP package requires PCB footprint verification for mechanical compatibility.

KBP01G from Diodes Incorporated is suitable only for applications where the average rectified current requirement does not exceed 1.5 A. This part offers the widest operating temperature range (-65°C to 150°C) and is actively produced with ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can KBP01G replace 2KBP01M/1 in all applications?

A: KBP01G is suitable only for applications requiring 1.5 A or less average rectified current. The 2KBP01M/1 is rated for 2 A; applications operating at or near this current level require VS-2KBP01 or KBP201G.

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

A: Both are 4-SIP through-hole packages. The D-44 (VS-2KBP01) and KBPM (2KBP01M/1) have different physical dimensions and pin configurations. PCB footprint compatibility must be verified before substitution.

Q: Does the operating temperature range difference affect substitution?

A: The 2KBP01M/1 operates to 165°C; substitute parts operate to 150°C maximum. Applications requiring operation above 150°C cannot use these substitutes. Applications operating within -40°C to 150°C are compatible with all three substitute options.

Q: Are all substitute parts RoHS compliant?

A: Yes. VS-2KBP01, KBP01G, and KBP201G are all ROHS3 compliant. The original 2KBP01M/1 is RoHS non-compliant.

Q: What is the significance of the forward voltage difference between parts?

A: Forward voltage specifications are provided at different test currents. VS-2KBP01 specifies 1 V @ 1 A; 2KBP01M/1 specifies 1.1 V @ 3.14 A. These differences reflect measurement conditions rather than functional incompatibility at equivalent operating points.
