Key Parameters

Substitute Part Grouping Explanation

Substitution of the MB352W-BP is determined by strict equivalence across the following critical parameters:

• Diode Type: Single Phase bridge rectifier configuration
• Voltage Rating: 200V peak reverse voltage (Vrrm)
• Current Rating: 35A average rectified current (Io)
• Forward Voltage: Maximum 1.2V @ 17.5A
• Reverse Leakage: 10 µA @ 200V
• Temperature Range: -55°C to 150°C junction temperature
• Mounting: Through-hole configuration
• Package Form Factor: 4-Square footprint compatibility

The KBPC3502W-G meets all substitution criteria and maintains electrical and mechanical compatibility with the MB352W-BP across these parameters.

Parameter Comparison

Engineering Selection Recommendations

The KBPC3502W-G is a direct functional equivalent to the MB352W-BP. Both components maintain identical electrical specifications for voltage rating, current capacity, and temperature operating range. The KBPC3502W-G offers the advantage of active product status, ensuring continued availability and supply chain reliability compared to the obsolete MB352W-BP.

Both parts comply with ROHS3 and REACH regulatory requirements, with identical moisture sensitivity classification (MSL 1). The forward voltage characteristic of the KBPC3502W-G is marginally lower (1.1V versus 1.2V @ 17.5A), which represents improved efficiency performance within the same electrical class.

Through-hole mounting compatibility and 4-Square package form factors are maintained between both components, supporting direct board-level substitution.

Frequently Asked Questions (FAQ)

Q: Can the KBPC3502W-G replace the MB352W-BP in existing designs?

A: Yes. Both components share identical voltage ratings (200V), current ratings (35A), temperature ranges (-55°C to 150°C), and through-hole mounting configurations. The 4-Square package footprints are mechanically compatible.

Q: What is the significance of the forward voltage difference between these parts?

A: The KBPC3502W-G exhibits a forward voltage of 1.1V @ 17.5A compared to 1.2V @ 17.5A for the MB352W-BP. This 0.1V difference represents improved efficiency and reduced power dissipation in the substitute component, with no negative impact on circuit functionality.

Q: Why is the MB352W-BP listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The KBPC3502W-G, maintained in active production status by Comchip Technology, provides continuity for applications requiring single-phase bridge rectification at 200V/35A ratings.

Q: Are there compliance or certification differences between these parts?

A: No. Both components maintain identical ROHS3 compliance, REACH unaffected status, and MSL 1 moisture sensitivity classification.

Q: What packaging formats are available for these parts?

A: The MB352W-BP is supplied in standard packaging, while the KBPC3502W-G is available in tray packaging. Both maintain the same 4-Square through-hole form factor for PCB integration.
