KBP01M Bridge Rectifier Single Phase 100V 1.5A Equivalent & Substitute Parts

Part Overview

The KBP01M is a single-phase bridge rectifier manufactured by onsemi, rated for 100 V peak reverse voltage and 1.5 A average rectified current in a 4-SIP KBPM through-hole package. This component 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 active product status and improved availability.

Substitute Part Grouping Explanation

Substitute parts for the KBP01M are selected based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

Diode Type: Single Phase (all substitutes)
Technology: Standard (all substitutes)
Voltage - Peak Reverse (Max): 100 V (direct equivalents)
Current - Average Rectified (Io): 1.5 A or higher (acceptable for uprating)
Mounting Type: Through Hole (all substitutes)

Substitution Logic: Parts with identical 100 V peak reverse voltage and 1.5 A or greater current rating are direct functional equivalents. Parts with higher voltage ratings (200 V, 400 V, 600 V, 800 V, 1 kV) are suitable for applications where the KBP01M is used in lower-voltage circuits, as they provide additional voltage margin. Parts with lower voltage ratings (50 V) are not suitable substitutes due to insufficient voltage rating.

Engineering Selection Recommendations

Direct Equivalents (100 V Rating): KBP01G and KBP201G are direct functional equivalents with active product status. KBP01G maintains the 1.5 A current rating and is the closest match. KBP201G provides higher current capacity (2 A) at the same voltage rating, suitable for applications requiring additional current margin. Both are available from active manufacturers with RoHS3 compliance.

Higher Voltage Alternatives (200 V, 400 V, 600 V, 800 V, 1 kV): The VS-2KBP series (VS-2KBP02, VS-2KBP04, VS-2KBP06, VS-2KBP08, VS-2KBP10) from Vishay General Semiconductor - Diodes Division are suitable substitutes for applications operating at voltages below their rated peak reverse voltage. These parts offer higher voltage ratings with 2 A current capacity and active product status with RoHS3 compliance. Selection depends on the actual operating voltage of the application.

Not Recommended: VS-2KBP005 (50 V rating) is not suitable as a substitute due to insufficient peak reverse voltage rating relative to the KBP01M specification.

Frequently Asked Questions (FAQ)

Q: Can KBP01G be used as a direct replacement for KBP01M? A: Yes. KBP01G maintains the same 100 V peak reverse voltage and 1.5 A current rating. Both are single-phase standard bridge rectifiers with through-hole mounting. KBP01G is manufactured by Diodes Incorporated with active product status and RoHS3 compliance.

Q: What is the difference between KBP01G and KBP201G? A: Both operate at 100 V peak reverse voltage. KBP01G is rated for 1.5 A average rectified current, while KBP201G is rated for 2 A. KBP201G provides higher current capacity and is manufactured by SMC Diode Solutions. Selection depends on application current requirements.

Q: Can I use a higher voltage-rated part like VS-2KBP06 (600 V) in place of KBP01M (100 V)? A: Yes, if the application operates at voltages below 600 V. Higher voltage-rated bridge rectifiers are suitable for lower-voltage applications and provide additional voltage margin. Verify that the application circuit does not exceed the substitute part's maximum operating temperature range (-40°C ~ 150°C for VS-2KBP06 versus -55°C ~ 165°C for KBP01M).

Q: Are there package compatibility considerations? A: KBP01M uses a 4-SIP KBPM package. KBP01G uses a 4-SIP KBP package, which is mechanically compatible. KBP201G uses a 4-ESIP package. VS-2KBP series parts use a 4-SIP D-44 package. Verify PCB footprint compatibility before selection, as package variants may have different pin spacing or lead configurations.

Q: What compliance certifications should I verify? A: All active substitute parts listed carry RoHS3 compliance. KBP01G, KBP201G, and VS-2KBP series are REACH compliant or REACH unaffected. Verify specific compliance requirements for your application and region before final selection.

Q: Why is VS-2KBP005 (50 V) not recommended? A: The 50 V peak reverse voltage rating is below the KBP01M specification of 100 V. Using an undersized voltage rating creates risk of component failure if transient voltages exceed the rated specification.
