MB2510W-BP Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The MB2510W-BP is a single-phase bridge rectifier manufactured by Micro Commercial Co, rated for 1 kV peak reverse voltage and 25 A average rectified current. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and procurement continuity. The through-hole MB-35W package configuration requires compatible alternatives that maintain electrical and mechanical compatibility with existing circuit designs.

Substitute Part Grouping Explanation

Substitution of the MB2510W-BP is determined by strict equivalence across the following critical parameters:

Diode Type: Single Phase bridge rectifier configuration
Peak Reverse Voltage: 1 kV minimum rating
Average Rectified Current: 25 A minimum rating
Mounting Type: Through Hole
Package Form Factor: 4-Square configuration compatible with MB-35W footprint
Regulatory Compliance: ROHS3 Compliant, REACH Unaffected

The KBPC2510W-G from Comchip Technology meets all substitution criteria. Both parts share identical electrical ratings for voltage and current specifications, equivalent reverse leakage characteristics, and compatible through-hole mounting. Package compatibility is maintained through the 4-Square form factor standard used in both MB-35W and KBPC-W configurations.

Engineering Selection Recommendations

The KBPC2510W-G is a direct substitute for the obsolete MB2510W-BP based on electrical equivalence and regulatory compliance alignment. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity in applications requiring these certifications.

The KBPC2510W-G offers operational advantages: lower forward voltage drop (1.1 V versus 1.2 V) reduces power dissipation, and extended operating temperature range (-55°C to 150°C versus -55°C to 125°C) provides thermal margin in high-temperature environments. These characteristics make the KBPC2510W-G suitable for direct replacement in existing MB2510W-BP circuit designs without modification.

Active manufacturing status of the KBPC2510W-G ensures long-term availability and supply chain stability compared to the obsolete MB2510W-BP.

Frequently Asked Questions (FAQ)

Q: Can the KBPC2510W-G be used as a direct replacement for MB2510W-BP without circuit modification?

A: Yes. Both parts are single-phase bridge rectifiers with identical 1 kV peak reverse voltage and 25 A average rectified current ratings. Through-hole mounting and 4-Square package compatibility enable direct substitution. The lower forward voltage of the KBPC2510W-G (1.1 V versus 1.2 V) is a beneficial characteristic that reduces power dissipation.

Q: Are there package footprint differences between MB-35W and KBPC-W?

A: Both use the 4-Square form factor standard for single-phase bridge rectifiers. The package designations (MB-35W and KBPC-W) reflect manufacturer-specific naming conventions but maintain compatible through-hole lead spacing and mounting geometry.

Q: What is the significance of the extended temperature range in the KBPC2510W-G?

A: The KBPC2510W-G operates to 150°C junction temperature versus 125°C for the MB2510W-BP. This extended range provides additional thermal margin in applications subject to elevated ambient temperatures or high power dissipation conditions.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both MB2510W-BP and KBPC2510W-G are ROHS3 compliant and REACH unaffected, maintaining equivalent regulatory status for applications requiring these certifications.

Q: Why is the MB2510W-BP classified as obsolete?

A: Obsolete status indicates the part is no longer manufactured by Micro Commercial Co. The KBPC2510W-G from Comchip Technology provides active manufacturing continuity for this electrical class of single-phase bridge rectifier.
