IRF7404PBF P-Channel MOSFET Equivalent & Substitute Parts

Part Overview

The IRF7404PBF is a P-Channel MOSFET manufactured by Infineon Technologies, rated for 20V drain-to-source voltage with 6.7A continuous drain current at 25°C. This device is part of the HEXFET® series and is packaged in an 8-SOIC surface mount configuration. The IRF7404PBF is currently discontinued at DiGi Electronics, making identification of equivalent substitute components essential for ongoing design support and production continuity. Substitute parts must maintain electrical and mechanical compatibility within the specified parameter ranges for this product category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the IRF7404PBF are selected based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

Critical Matching Parameters:

• FET Type: P-Channel topology
• Package / Case: 8-SOIC (0.154", 3.90mm Width) surface mount configuration
• Drain to Source Voltage (Vdss): Minimum 20V rating required
• Continuous Drain Current (Id): Minimum 6.5A at 25°C
• Operating Temperature Range: -55°C to 150°C
• RoHS Compliance: ROHS3 Compliant

Two substitute parts meet these criteria:

DMP2038USS-13 (Diodes Incorporated): Matches the 20V voltage class with 6.5A continuous drain current, identical package configuration, and equivalent power dissipation of 2.5W. This substitute provides direct voltage and current compatibility.

DMP4025LSS-13 (Diodes Incorporated): Operates at 40V drain-to-source voltage with 6A continuous drain current. While the voltage rating exceeds the original specification, this part maintains the same 8-SOIC package and operating temperature range, providing enhanced voltage margin for applications requiring higher transient protection.

Parameter Comparison

Engineering Selection Recommendations

DMP2038USS-13 Selection Criteria:

The DMP2038USS-13 is the primary substitute for direct replacement applications. This part maintains identical voltage rating (20V Vdss) and equivalent continuous drain current (6.5A versus 6.7A). Power dissipation is matched at 2.5W maximum. The device is manufactured by Diodes Incorporated with active product status and full ROHS3 compliance. Packaging is identical 8-SOIC configuration. This substitute is suitable for applications where the original 20V voltage class is specified and current requirements do not exceed 6.5A.

DMP4025LSS-13 Selection Criteria:

The DMP4025LSS-13 serves as a substitute for applications requiring enhanced voltage margin or where 40V rated components are preferred for system-level protection. The doubled voltage rating (40V versus 20V) provides additional transient voltage suppression capability. Continuous drain current is rated at 6A, which is within acceptable range for most applications originally designed for 6.7A. Power dissipation is reduced to 1.52W, indicating improved thermal performance. This part is suitable for designs where voltage headroom is a design consideration or where component standardization across multiple voltage classes is required.

Both substitutes maintain full compliance with RoHS3 and REACH requirements. Operating temperature range is preserved at -55°C to 150°C for both alternatives.

Frequently Asked Questions (FAQ)

Q: Can DMP2038USS-13 be used as a direct replacement for IRF7404PBF?

A: Yes. The DMP2038USS-13 maintains the same 20V voltage rating, equivalent 6.5A continuous drain current, identical 8-SOIC package, and matching 2.5W power dissipation. Both devices operate across -55°C to 150°C and are ROHS3 compliant. This is the recommended substitute for direct replacement applications.

Q: What is the difference between DMP2038USS-13 and DMP4025LSS-13?

A: The primary difference is drain-to-source voltage rating. DMP2038USS-13 is rated for 20V (matching the original IRF7404PBF), while DMP4025LSS-13 is rated for 40V. Both use identical 8-SOIC packaging. DMP4025LSS-13 provides higher voltage margin and lower power dissipation (1.52W versus 2.5W), but continuous drain current is reduced to 6A.

Q: Are both substitute parts available in the same packaging as the original IRF7404PBF?

A: Yes. Both DMP2038USS-13 and DMP4025LSS-13 are packaged in 8-SOIC (0.154", 3.90mm Width) surface mount configuration, identical to the IRF7404PBF. PCB layout and footprint compatibility are maintained.

Q: What is the continuous drain current difference between IRF7404PBF and its substitutes?

A: IRF7404PBF is rated for 6.7A continuous drain current at 25°C. DMP2038USS-13 is rated for 6.5A (0.2A reduction), and DMP4025LSS-13 is rated for 6A (0.7A reduction). Applications operating below these current levels will not be affected by these differences.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both DMP2038USS-13 and DMP4025LSS-13 are ROHS3 compliant and REACH unaffected, matching the compliance status of the original IRF7404PBF.

Q: Which substitute should be selected for new designs?

A: For new designs requiring 20V P-Channel MOSFETs in 8-SOIC packaging, DMP2038USS-13 is recommended due to active product status, equivalent electrical specifications, and established supply chain availability. DMP4025LSS-13 is suitable for designs where 40V voltage rating provides system-level advantages.
