Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IPP65R310CFDXKSA2 is determined by the following critical parameters:

Voltage Rating (Vdss): The drain-source voltage must equal or exceed 650V to maintain circuit protection margins.

Continuous Drain Current (Id): The substitute must support at least 11.4A continuous current at 25°C to handle the same load conditions.

On-State Resistance (Rds On): Lower or equivalent resistance ensures comparable power dissipation and thermal performance.

Gate Charge (Qg): Similar gate charge values ensure compatible switching characteristics and driver circuit performance.

Package and Mounting: All substitutes must use TO-220-3 through-hole packaging to maintain mechanical and thermal interface compatibility.

Operating Temperature: All candidates maintain the -55°C to 150°C operating range.

The three identified substitutes are grouped as follows:

Group 1 (Lower Voltage, Lower Current): FCP380N60 operates at 600V with 10.2A, suitable for applications with reduced voltage stress requirements.

Group 2 (Higher Voltage, Higher Current): FCP400N80Z operates at 800V with 14A, suitable for applications requiring enhanced voltage headroom and current capacity.

Group 3 (Matched Voltage, Comparable Current): STP13NM60N operates at 600V with 11A, providing near-equivalent performance in the 600V class.

Engineering Selection Recommendations

For Active Product Status Requirement:

The IPP65R310CFDXKSA2 and STP13NM60N are both Active products. STP13NM60N is the preferred substitute when product lifecycle continuity is required for long-term production applications. Both parts carry ROHS3 compliance and unlimited moisture sensitivity level (MSL 1).

For Voltage Margin Applications:

FCP400N80Z provides 800V rating, offering 150V additional margin above the 650V specification. This substitute is appropriate for circuits requiring enhanced transient voltage protection. However, FCP400N80Z is marked Not For New Designs, limiting its use to legacy system support or existing inventory management.

For Current-Constrained Applications:

FCP380N60 operates at 600V with 10.2A continuous current. This substitute is suitable only for applications where the load current does not exceed 10.2A. FCP380N60 is also marked Not For New Designs.

Compliance Considerations:

All four parts maintain ROHS3 compliance, REACH Unaffected status, and EAR99 export classification. All operate within -55°C to 150°C temperature range. Thermal design must account for power dissipation differences: FCP400N80Z dissipates 195W versus 104.2W for the main part.

Frequently Asked Questions (FAQ)

Q: Can FCP380N60 directly replace IPP65R310CFDXKSA2 in all applications?

A: FCP380N60 is suitable only for applications where continuous drain current does not exceed 10.2A and where 600V voltage rating is acceptable. The 650V main part provides 50V additional margin. Verify circuit current requirements before substitution.

Q: What is the primary difference between FCP400N80Z and the main part?

A: FCP400N80Z operates at 800V with 14A continuous current and 195W power dissipation, compared to 650V, 11.4A, and 104.2W for IPP65R310CFDXKSA2. The higher voltage and current ratings require thermal design review. FCP400N80Z is marked Not For New Designs.

Q: Why is STP13NM60N recommended over the onsemi alternatives?

A: STP13NM60N maintains Active product status, matching the main part's lifecycle status. Both IPP65R310CFDXKSA2 and STP13NM60N are Active products suitable for new designs. The onsemi parts are marked Not For New Designs, limiting their application to legacy support.

Q: Are all substitutes compatible with TO-220-3 mounting?

A: Yes. All four parts use TO-220-3 through-hole packaging, ensuring mechanical and thermal interface compatibility. PCB layout and heatsink mounting remain unchanged.

Q: How do gate charge differences affect circuit performance?

A: IPP65R310CFDXKSA2 has 41nC gate charge, STP13NM60N has 30nC, FCP380N60 has 40nC, and FCP400N80Z has 56nC. Lower gate charge (STP13NM60N) reduces driver power consumption and switching losses. Higher gate charge (FCP400N80Z) requires higher driver current capability. Verify driver circuit specifications before substitution.

Q: What thermal considerations apply when substituting FCP400N80Z?

A: FCP400N80Z dissipates 195W maximum, nearly double the 104.2W of the main part. Heatsink thermal resistance must be recalculated to maintain junction temperature within -55°C to 150°C operating range. Thermal interface material and mounting pressure may require adjustment.

Q: Are moisture sensitivity levels equivalent across all parts?

A: IPP65R310CFDXKSA2 and STP13NM60N specify MSL 1 (Unlimited). FCP380N60 and FCP400N80Z specify Not Applicable. All parts are suitable for standard PCB assembly processes without special moisture control requirements.
