IRFP4004PBF Equivalent & Substitute Parts

Part Overview

The IRFP4004PBF is an N-Channel MOSFET manufactured by Infineon Technologies, rated for 40V drain-to-source voltage with 195A continuous drain current at 25°C. This device features the HEXFET® series technology and is housed in a TO-247AC through-hole package. The part is designated as "Not For New Designs," indicating it has been superseded in Infineon's product portfolio. Identification of equivalent and substitute parts is necessary for applications requiring continued sourcing, design flexibility, or performance optimization within the 40V N-Channel MOSFET category.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IRFP4004PBF within the 40V N-Channel MOSFET category is determined by the following critical parameters:

Voltage Rating Compatibility: All substitute parts must maintain the same 40V Vdss rating to ensure safe operation within the intended application voltage envelope.

Package Compatibility: The IRFP4004PBF uses a TO-247AC through-hole package. Substitute parts must use mechanically compatible through-hole packages (TO-247AC, TO-247, or TO-247-3 variants) to ensure direct board-level compatibility without redesign.

Current and Thermal Performance: While the IRFP4004PBF specifies 195A continuous drain current, substitute parts with higher current ratings (500A, 600A) and increased power dissipation capability (1000W, 1250W) provide enhanced thermal margin and current headroom. These higher-rated devices remain functionally compatible as they operate within the same voltage class and package family.

Gate Drive Characteristics: All substitute parts operate with 10V drive voltage and maintain compatible gate threshold voltage ranges (3.5V to 4V @ 250µA), ensuring compatibility with existing gate drive circuits.

Compliance and Status: Substitute parts must maintain RoHS3 compliance, unlimited moisture sensitivity level (MSL 1), and active product status to ensure long-term availability and regulatory alignment.

Parameter Comparison

Engineering Selection Recommendations

IXTH500N04T2 (IXYS): This substitute part maintains the 40V voltage rating and provides 500A continuous drain current with 1.7mOhm on-state resistance specification at 100A. The IXTH500N04T2 features active product status and full RoHS3 compliance. The TO-247 (IXTH) package is mechanically compatible with TO-247AC footprints. This device is suitable for applications requiring higher current capacity than the IRFP4004PBF while maintaining thermal performance within the same package family.

IXTX600N04T2 (IXYS): This substitute part maintains the 40V voltage rating and provides 600A continuous drain current with 1.5mOhm on-state resistance specification at 100A. The IXTX600N04T2 features active product status and full RoHS3 compliance. The PLUS247™-3 package is a TO-247-3 variant compatible with standard TO-247 footprints. This device is suitable for applications requiring maximum current capacity and lowest on-state resistance within the 40V N-Channel MOSFET class.

Both substitute parts are recommended for new designs and ongoing production due to their active product status, superior thermal performance, and enhanced current ratings compared to the IRFP4004PBF.

Frequently Asked Questions (FAQ)

Q: Can the IXTH500N04T2 or IXTX600N04T2 be used as direct replacements for the IRFP4004PBF?

A: Yes. Both substitute parts share the same 40V Vdss rating, N-Channel MOSFET technology, and compatible through-hole package families (TO-247 variants). The higher current ratings and lower on-state resistance values provide enhanced performance without compromising circuit compatibility.

Q: What is the difference between the IXTH500N04T2 and IXTX600N04T2?

A: The IXTX600N04T2 provides higher continuous drain current (600A versus 500A) and lower on-state resistance (1.5mOhm versus 1.6mOhm at 100A). The IXTX600N04T2 uses the PLUS247™-3 package variant, while the IXTH500N04T2 uses the standard TO-247 (IXTH) package. Both are mechanically compatible with TO-247AC footprints.

Q: Are there package compatibility concerns when substituting the IRFP4004PBF?

A: The IRFP4004PBF uses TO-247AC packaging. The IXTH500N04T2 (TO-247 IXTH) and IXTX600N04T2 (PLUS247™-3) are both TO-247-3 variant packages with identical pin configurations and mechanical compatibility. No PCB redesign is required for substitution.

Q: How do gate charge differences affect circuit performance?

A: The IRFP4004PBF specifies 330nC gate charge at 10V. The IXTH500N04T2 specifies 405nC, and the IXTX600N04T2 specifies 590nC. Higher gate charge requires proportionally longer switching times with the same gate drive circuit. Gate drive circuits with adequate current sourcing capability accommodate these differences without performance degradation.

Q: What is the significance of the "Not For New Designs" status of the IRFP4004PBF?

A: This designation indicates the IRFP4004PBF has been superseded in Infineon's product portfolio. Both substitute parts (IXTH500N04T2 and IXTX600N04T2) carry active product status, ensuring long-term availability, continued manufacturing support, and alignment with current industry standards.

Q: Are all three parts RoHS3 compliant?

A: Yes. The IRFP4004PBF, IXTH500N04T2, and IXTX600N04T2 are all RoHS3 compliant with MSL 1 (unlimited moisture sensitivity level), ensuring regulatory compliance and environmental safety across all three devices.
