2KBP02M Bridge Rectifier Single Phase 200V 2A Equivalent & Substitute Parts

Part Overview

The 2KBP02M is a single-phase bridge rectifier manufactured by onsemi, rated for 200V peak reverse voltage and 2A average rectified current. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. The 2KBP02M features a 4-SIP KBPM package with through-hole mounting, suitable for standard rectification applications requiring 200V operation.

Substitute Part Grouping Explanation

Substitution for the 2KBP02M is determined by the following critical parameters:

Voltage - Peak Reverse (Max): 200 V minimum requirement
Current - Average Rectified (Io): 2 A minimum requirement
Diode Type: Single Phase
Technology: Standard
Mounting Type: Through Hole

Substitute parts are grouped into two categories:

Category 1 - Direct Electrical Equivalents (200V, 2A): Parts meeting or exceeding the exact voltage and current specifications with active product status and modern compliance certifications.

Category 2 - Functional Alternatives (200V, ≥2A): Parts with matching voltage ratings and equal or higher current capacity, suitable for direct replacement in circuit designs.

Category 3 - Voltage-Variant Alternatives: Parts from the same series with different voltage ratings, applicable only when circuit voltage requirements differ from the original 200V specification.

Engineering Selection Recommendations

Primary Substitutes for 200V, 2A Applications:

KBP202G (SMC Diode Solutions) and VS-2KBP02 (Vishay) are the preferred direct substitutes for the 2KBP02M. Both parts maintain the 200V peak reverse voltage and 2A average rectified current specifications. KBP202G carries active product status with ROHS3 compliance. VS-2KBP02 is active with ROHS3 compliance and offers extended temperature range capability at the lower operating limit (-40°C vs. -55°C).

Secondary Substitute for Current-Limited Applications:

KBP02G (Diodes Incorporated) operates at 200V peak reverse voltage with 1.5A average rectified current. This part is suitable only for applications where the circuit current requirement does not exceed 1.5A. KBP02G provides active product status, ROHS3 compliance, and an extended lower operating temperature limit (-65°C).

Voltage-Variant Alternatives:

VS-2KBP005, VS-2KBP04, VS-2KBP06, VS-2KBP08, and VS-2KBP10 are functional alternatives from the Vishay VS-2KBP series with voltage ratings of 50V, 400V, 600V, 800V, and 1kV respectively. These parts maintain 2A average rectified current and are applicable only when circuit voltage requirements differ from the original 200V specification. All carry active product status and ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can KBP02G replace the 2KBP02M in all applications?

A: KBP02G is electrically compatible at 200V operation but is rated for 1.5A average rectified current versus the 2KBP02M's 2A rating. Substitution is valid only if the circuit current requirement does not exceed 1.5A. For applications requiring the full 2A capacity, use KBP202G or VS-2KBP02 instead.

Q: What is the difference between the 4-SIP KBPM package and the 4-SIP D-44 package?

A: Both are 4-pin single in-line packages with through-hole mounting. The KBPM designation is specific to onsemi, while D-44 is the Vishay equivalent. Physical dimensions and pin spacing may differ slightly. Verify PCB footprint compatibility before substitution.

Q: Are the Vishay VS-2KBP voltage variants (50V, 400V, 600V, 800V, 1kV) suitable replacements for the 200V application?

A: No. These parts are voltage-variant alternatives applicable only when the circuit voltage requirement differs from 200V. Using a lower voltage rating (VS-2KBP005 at 50V) creates an overstress condition. Using a higher voltage rating introduces unnecessary cost and may alter circuit performance characteristics. Select the voltage rating matching your circuit requirement.

Q: What compliance certifications should I verify for new designs?

A: All active substitute parts listed carry ROHS3 compliance. The 2KBP02M does not specify RoHS status due to its obsolete classification. For new designs, KBP202G and VS-2KBP02 are recommended as both maintain active product status with current compliance certifications.

Q: How do forward voltage characteristics compare between substitutes?

A: The 2KBP02M specifies 1.1V forward voltage at 3.14A. KBP202G matches this at 1.1V @ 2A. VS-2KBP series parts specify 1V @ 1A, which is lower but measured at reduced current. Forward voltage varies with current; direct comparison requires measurement at identical current levels. For circuit design purposes, use the specified values at the rated current for each part.

Q: Can I use VS-2KBP02 in place of 2KBP02M without PCB modification?

A: VS-2KBP02 uses the 4-SIP D-44 package while 2KBP02M uses 4-SIP KBPM. Although both are 4-pin through-hole packages, physical dimensions and pin spacing may differ. Verify PCB footprint compatibility and pin assignment before substitution. If footprints are incompatible, PCB modification is required.
