Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MB356W-BP are qualified based on the following electrical and mechanical parameters:

• Diode Type: Single Phase
• Technology: Standard
• Voltage - Peak Reverse (Max): 600 V
• Current - Average Rectified (Io): 35 A
• Operating Temperature Range: -55°C ~ 150°C (TJ)
• Mounting Type: Through Hole
• Package Configuration: 4-Square form factor

The substitute parts GBPC3506W-G and KBPC3506W-G meet all critical electrical specifications and maintain through-hole mounting compatibility. Both substitutes are manufactured by Comchip Technology and carry active product status, providing long-term availability advantages over the obsolete MB356W-BP.

Parameter Comparison

Engineering Selection Recommendations

Both GBPC3506W-G and KBPC3506W-G are suitable substitutes for the obsolete MB356W-BP. The substitute parts maintain electrical equivalence across all critical parameters: 600V peak reverse voltage, 35A average rectified current, and identical operating temperature range.

GBPC3506W-G and KBPC3506W-G both carry active product status, ensuring continued availability and supply chain stability. Both substitutes are ROHS3 compliant and REACH unaffected, matching the regulatory compliance profile of the original part. The forward voltage specification of the substitutes (1.1V @ 17.5A) is lower than the MB356W-BP (1.2V @ 17.5A), representing an improvement in thermal efficiency.

All three parts maintain the through-hole 4-Square package form factor, supporting direct mechanical compatibility in existing PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can GBPC3506W-G and KBPC3506W-G be used interchangeably with MB356W-BP?

A: Yes. Both substitute parts meet the electrical specifications of the MB356W-BP across voltage, current, and temperature parameters. The through-hole 4-Square package configuration ensures mechanical compatibility with existing designs.

Q: What is the difference between GBPC3506W-G and KBPC3506W-G?

A: Both parts are manufactured by Comchip Technology and share identical electrical specifications. The primary difference is the package designation: GBPC3506W-G uses the GBPC-W package, while KBPC3506W-G uses the KBPC-W package. Both are 4-Square form factors compatible with MB-35W footprints.

Q: Why is the MB356W-BP classified as obsolete?

A: The MB356W-BP is listed as obsolete by the manufacturer. GBPC3506W-G and KBPC3506W-G are active products from Comchip Technology, providing long-term procurement and supply continuity.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both GBPC3506W-G and KBPC3506W-G are ROHS3 compliant and REACH unaffected, matching the regulatory status of the MB356W-BP.

Q: What is the forward voltage difference between the original and substitute parts?

A: The MB356W-BP specifies 1.2V forward voltage at 17.5A, while both GBPC3506W-G and KBPC3506W-G specify 1.1V at the same current. This 0.1V reduction in the substitutes results in lower power dissipation and improved thermal performance.

Q: Are there any package considerations for PCB layout?

A: All three parts use through-hole 4-Square package configurations. Existing PCB layouts designed for the MB356W-BP will accommodate GBPC3506W-G and KBPC3506W-G without modification.
