KBPM201G Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The KBPM201G is a single-phase bridge rectifier manufactured by GeneSiC Semiconductor, rated for 100 V peak reverse voltage and 2 A average rectified current. This component is classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing design support and procurement continuity. The KBPM201G features a through-hole 4-SIP package configuration suitable for standard PCB assembly applications.

Substitute Part Grouping Explanation

Substitution of the KBPM201G is determined by the following critical electrical and mechanical parameters:

Current Rating: The substitute must support a minimum average rectified current of 2 A to maintain circuit functionality.

Mounting Configuration: The substitute must utilize through-hole mounting with a 4-SIP package footprint to ensure PCB compatibility without redesign.

Diode Type and Technology: The substitute must be a single-phase standard bridge rectifier to match the original application topology.

Voltage Rating: The substitute must have a peak reverse voltage rating equal to or greater than 100 V. Higher voltage ratings are acceptable as they provide design margin and do not compromise circuit operation in lower-voltage applications.

Temperature Range: The substitute must support the operating temperature range of -55°C to 150°C or a range that encompasses the application requirements.

The KBP202 satisfies these substitution criteria with a 200 V peak reverse voltage rating (exceeding the 100 V requirement), 2 A current rating, through-hole 4-SIP package configuration, and compatible temperature operating range.

Engineering Selection Recommendations

Primary Substitute: KBP202

The KBP202 is the recommended substitute for the obsolete KBPM201G based on the following engineering criteria:

Electrical Compatibility: The KBP202 maintains the 2 A current rating and through-hole 4-SIP package configuration. The 200 V peak reverse voltage rating exceeds the KBPM201G requirement of 100 V, providing additional design margin without adverse effects in 100 V applications.

Product Status and Availability: The KBP202 is classified as active with 7613 units in stock, ensuring procurement continuity and long-term supply reliability compared to the obsolete KBPM201G status.

Compliance and Certifications: The KBP202 is RoHS3 compliant, meeting current environmental and regulatory standards. REACH information is available upon request from the manufacturer.

Temperature Operating Range Consideration: The KBP202 operating range (-50°C to 125°C) is narrower than the KBPM201G range (-55°C to 150°C). Applications requiring operation below -50°C or above 125°C must verify compatibility with the substitute or identify alternative parts.

Forward Voltage Characteristics: The KBP202 exhibits lower forward voltage (1 V @ 1 A) compared to the KBPM201G (1.1 V @ 2 A), resulting in reduced power dissipation and improved thermal performance in the application circuit.

Frequently Asked Questions (FAQ)

Q: Can the KBP202 be used as a direct replacement for the KBPM201G without PCB modifications?

A: Yes. Both components utilize the 4-SIP through-hole package configuration with identical pin spacing and footprint. No PCB layout changes are required for mechanical substitution.

Q: Why is the KBP202 rated for 200 V when the KBPM201G is rated for 100 V?

A: The higher voltage rating in the KBP202 provides design margin and does not compromise operation in 100 V applications. The component will function correctly at voltages up to its rated maximum. The 100 V application operates well within the KBP202 specification envelope.

Q: What is the impact of the narrower temperature range in the KBP202?

A: The KBP202 operates from -50°C to 125°C, compared to the KBPM201G range of -55°C to 150°C. If the application requires operation below -50°C or above 125°C, the KBP202 is not suitable. Verify the actual operating temperature requirements of your circuit before substitution.

Q: Are there any differences in reverse leakage current between these parts?

A: The KBPM201G specifies 5 µA @ 50 V, while the KBP202 specifies 10 µA @ 200 V. These measurements are taken at different voltage levels, making direct comparison inappropriate. Both values are within acceptable ranges for standard bridge rectifier applications.

Q: Is the KBP202 RoHS compliant?

A: Yes. The KBP202 is RoHS3 compliant, meeting current environmental regulations. The KBPM201G REACH status is listed as unaffected, but the KBP202 provides verified compliance documentation available upon request from the manufacturer.

Q: What is the packaging difference between KBPM and KBP designations?

A: Both designations refer to 4-SIP through-hole packages. The KBPM and KBP are manufacturer-specific package identifiers for GeneSiC Semiconductor and EIC SEMICONDUCTOR INC., respectively. The physical dimensions and pin configurations are compatible for PCB substitution.
