MB152W-BP Bridge Rectifier Single Phase 200V 15A Equivalent & Substitute Parts

Part Overview

The MB152W-BP is a single-phase bridge rectifier manufactured by Micro Commercial Co, rated for 200V peak reverse voltage and 15A average rectified current. This component is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing system maintenance and new design implementations. The MB152W-BP operates across a temperature range of -55°C to 125°C and is housed in a 4-Square MB-35W through-hole package.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MB152W-BP is determined by strict equivalence across the following critical parameters:

• Diode Type: Single Phase
• Voltage - Peak Reverse (Max): 200 V
• Current - Average Rectified (Io): 15 A
• Mounting Type: Through Hole
• Package / Case: 4-Square configuration

The KBPC1502W-G manufactured by Comchip Technology meets all substitution criteria. Both parts share identical peak reverse voltage, average rectified current, diode type, and through-hole mounting configuration. The KBPC1502W-G maintains compatibility with the MB-35W footprint through its 4-Square KBPC-W package designation.

Parameter Comparison

Engineering Selection Recommendations

The KBPC1502W-G is a direct substitute for the obsolete MB152W-BP. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The substitute part is currently in active production status with 1021 units available in inventory, compared to the obsolete status of the original part with 915 units remaining.

The KBPC1502W-G demonstrates improved forward voltage characteristics (1.1 V versus 1.2 V at 7.5 A), resulting in lower power dissipation. The extended operating temperature range of the substitute (-55°C to 150°C versus -55°C to 125°C) provides additional thermal margin for applications operating at elevated junction temperatures.

Both parts maintain identical electrical performance across peak reverse voltage, average rectified current, and reverse leakage specifications. The 4-Square through-hole package configuration ensures mechanical and electrical compatibility in existing PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can the KBPC1502W-G replace the MB152W-BP in existing designs?

A: Yes. Both parts share identical peak reverse voltage (200 V), average rectified current (15 A), reverse leakage current (10 µA @ 200 V), and through-hole 4-Square package configuration. The KBPC1502W-G is electrically and mechanically compatible.

Q: What are the differences between these two parts?

A: The primary differences are manufacturer (Micro Commercial Co versus Comchip Technology), product status (obsolete versus active), forward voltage (1.2 V versus 1.1 V at 7.5 A), and maximum operating temperature (125°C versus 150°C). The KBPC1502W-G offers lower forward voltage drop and extended temperature range.

Q: Are both parts RoHS compliant?

A: Yes. Both the MB152W-BP and KBPC1502W-G are ROHS3 compliant and REACH unaffected.

Q: What is the package compatibility between MB-35W and KBPC-W?

A: Both packages are 4-Square through-hole configurations. The mechanical footprint and pin configuration are compatible for direct PCB substitution.

Q: Why is the MB152W-BP listed as obsolete?

A: The MB152W-BP has reached end-of-life status with the manufacturer. The KBPC1502W-G remains in active production and is the recommended substitute for new designs and ongoing system support.
