Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB3505W-BP is determined by strict equivalence across the following critical parameters:

• Diode Type: Single Phase
• Technology: Standard
• Voltage - Peak Reverse (Max): 50 V
• Current - Average Rectified (Io): 35 A
• Mounting Type: Through Hole
• Package / Case: 4-Square configuration
• Operating Temperature Range: -55°C ~ 150°C (TJ)

The KBPC35005W-G manufactured by Comchip Technology meets all substitution criteria. Both components share identical electrical ratings, thermal operating range, and through-hole mounting configuration. The 4-Square package geometry ensures mechanical compatibility with existing PCB layouts designed for the MB3505W-BP.

Parameter Comparison

Engineering Selection Recommendations

The KBPC35005W-G is a direct electrical and mechanical equivalent to the MB3505W-BP. Both components are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The KBPC35005W-G maintains active product status with confirmed inventory availability, whereas the MB3505W-BP is obsolete. The forward voltage specification of the KBPC35005W-G (1.1 V @ 17.5 A) is marginally lower than the MB3505W-BP (1.2 V @ 17.5 A), representing improved efficiency characteristics while remaining within standard bridge rectifier performance parameters. Both components operate across the identical temperature range and share equivalent reverse leakage characteristics.

Frequently Asked Questions (FAQ)
