IXFX250N10P N-Channel MOSFET Equivalent & Substitute Parts

Part Overview

The IXFX250N10P is an N-Channel MOSFET manufactured by IXYS, part of the HiPerFET™ series. This device is rated for 100V drain-to-source voltage with a continuous drain current of 250A at 25°C and maximum power dissipation of 1250W. The component features a Through Hole PLUS247™-3 package configuration and is currently in Active product status with full RoHS3 compliance.

Substitute parts are identified when equivalent electrical performance parameters and mechanical compatibility exist within the same package family, enabling direct replacement in circuit applications where the main part number becomes unavailable or when inventory constraints require alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the IXFX250N10P are identified based on strict electrical and mechanical compatibility criteria. The primary substitution logic is based on the following parameters:

Critical Matching Parameters:

• Drain to Source Voltage (Vdss): 100V
• FET Type: N-Channel
• Technology: MOSFET (Metal Oxide)
• Mounting Type: Through Hole
• Package Family: TO-247-3 variant
• Operating Temperature Range: -55°C to 175°C
• Gate Voltage Rating (Vgs): ±20V
• RoHS3 Compliance: Required
• Product Status: Active

Substitution Constraints: The IRFP4310ZPBF meets the voltage rating, package family, temperature range, and compliance requirements. However, the continuous drain current rating of 120A (Tc) is lower than the main part's 250A specification. This substitute is classified as a functional equivalent for applications where the lower current rating is acceptable within the circuit design parameters.

Parameter Comparison

Engineering Selection Recommendations

IXFX250N10P (Primary Part): The IXFX250N10P remains the preferred selection for applications requiring the full 250A continuous drain current specification and 1250W power dissipation capability. This part is Active in product status with full RoHS3 compliance and REACH unaffected designation. Current inventory of 820 pieces supports immediate availability.

IRFP4310ZPBF (Substitute Part): The IRFP4310ZPBF is suitable as a substitute in applications where the continuous drain current requirement does not exceed 120A and power dissipation remains within the 280W maximum rating. This part is also Active in product status with equivalent RoHS3 compliance and REACH unaffected status. The substitute offers higher inventory availability with 16005 pieces in stock. Both parts share identical operating temperature range (-55°C to 175°C), gate voltage ratings (±20V), and TO-247-3 package family compatibility.

The selection between these parts must be based on the specific circuit current and power requirements. Direct substitution is not recommended for applications designed around the 250A specification.

Frequently Asked Questions (FAQ)

Q: Can the IRFP4310ZPBF directly replace the IXFX250N10P in all applications?

A: No. While both parts share the same voltage rating (100V), operating temperature range, and package family, the IRFP4310ZPBF has a maximum continuous drain current of 120A compared to the IXFX250N10P's 250A. Direct replacement is only valid in circuits where the actual drain current requirement does not exceed 120A and power dissipation remains below 280W.

Q: Are the package dimensions identical between these two parts?

A: Both parts use the TO-247-3 package family with Through Hole mounting. The IXFX250N10P uses the PLUS247™-3 variant while the IRFP4310ZPBF uses the TO-247AC variant. These are mechanically compatible within the TO-247-3 family and share the same pin configuration for Through Hole mounting applications.

Q: What is the significance of the different gate charge specifications?

A: The IXFX250N10P has a gate charge of 205 nC at 10V, while the IRFP4310ZPBF has 170 nC at 10V. Lower gate charge typically results in faster switching characteristics. This difference may affect gate driver requirements and switching frequency performance in high-speed applications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the IXFX250N10P and IRFP4310ZPBF are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8541.29.0095. Both have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity constraints.

Q: What is the difference in input capacitance between these parts?

A: The IXFX250N10P has an input capacitance (Ciss) of 16000 pF at 25V, while the IRFP4310ZPBF has 6860 pF at 50V. The higher input capacitance of the main part may require different gate driver characteristics and switching speed considerations in circuit design.

Q: Are there any thermal management differences between these parts?

A: Yes. The IXFX250N10P has a maximum power dissipation of 1250W (Tc), while the IRFP4310ZPBF is rated for 280W (Tc). Applications requiring higher power dissipation must use the IXFX250N10P or implement additional thermal management solutions with the substitute part.
