Key Parameters

Substitute Part Grouping Explanation

Substitution of the MB156W-BP is determined by strict equivalence across the following critical parameters:

• Voltage - Peak Reverse (Max): 600 V minimum
• Current - Average Rectified (Io): 15 A minimum
• Diode Type: Single Phase
• Technology: Standard
• Mounting Type: Through Hole
• Package compatibility: 4-Square form factor

The KBPC1506W-G manufactured by Comchip Technology meets all substitution criteria. Both parts share identical voltage and current ratings, operate as single-phase standard bridge rectifiers, and utilize through-hole mounting in compatible 4-Square package formats. The substitute part maintains full electrical and mechanical compatibility for direct replacement applications.

Parameter Comparison

Engineering Selection Recommendations

The KBPC1506W-G is a direct functional equivalent to the obsolete MB156W-BP. Both components satisfy identical electrical specifications for voltage and current ratings, maintain equivalent reverse leakage characteristics, and comply with ROHS3 and REACH regulatory requirements. The substitute part offers an extended operating temperature range (-55°C to 150°C versus -55°C to 125°C), providing additional thermal margin in high-temperature applications. The KBPC1506W-G maintains active product status with established supply availability, addressing the obsolescence of the original MB156W-BP.

Frequently Asked Questions (FAQ)

Q: Can the KBPC1506W-G replace the MB156W-BP in existing designs?

A: Yes. Both parts are rated for 600V peak reverse voltage and 15A average rectified current with identical single-phase standard bridge rectifier specifications. Through-hole mounting and 4-Square package compatibility enable direct substitution.

Q: What are the differences between these parts?

A: The KBPC1506W-G exhibits a lower forward voltage drop (1.1V versus 1.2V at 7.5A) and an extended maximum operating temperature range (150°C versus 125°C). The MB156W-BP is obsolete while the KBPC1506W-G maintains active status.

Q: Are there package compatibility concerns?

A: Both parts use 4-Square through-hole packages. The MB-35W and KBPC-W designations refer to manufacturer-specific package variants within the same form factor, maintaining mechanical and electrical compatibility for PCB mounting.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the MB156W-BP and KBPC1506W-G are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings.

Q: Which part should be selected for new designs?

A: The KBPC1506W-G is the appropriate selection for new designs due to its active product status, established supply chain, and superior thermal operating range.
