Equivalent & Substitute Parts for Infineon IRL1404 N-Channel MOSFET 40V 75A TO-220AB

Part Overview

The Infineon IRL1404 (manufacturer part number 64-8016) is an N-Channel MOSFET rated for 40V drain-source voltage with 75A continuous drain current in a TO-220AB through-hole package. This device belongs to the HEXFET® series and is classified as obsolete. Due to its obsolete status and limited availability in certain packaging configurations, equivalent and substitute parts from active product lines are necessary for new designs and ongoing production requirements. The substitute parts listed maintain electrical compatibility within defined parameter ranges while offering improved availability and compliance status.

Substitute Part Grouping Explanation

Substitution of the IRL1404 is determined by the following critical electrical and mechanical parameters:

Primary Compatibility Criteria:

Drain-Source Voltage (Vdss): Must equal or exceed 40V
Package Type: TO-220-3 through-hole configuration
FET Type: N-Channel MOSFET
Operating Temperature Range: Must support -55°C to 175°C (TJ)

Secondary Compatibility Criteria:

Continuous Drain Current (Id): Minimum 75A at 25°C (Tc)
On-State Resistance (Rds On): Lower values indicate improved performance; values up to 4.1 mOhm are acceptable
Gate Threshold Voltage (Vgs(th)): Range 2.0V to 4.0V acceptable
Gate Charge (Qg): Values between 56 nC and 162 nC acceptable
Power Dissipation: Minimum 94W (Tc)

Substitute parts are grouped into two categories:

Category A - Direct Equivalents (Identical Electrical Performance): Parts with matching or superior electrical specifications and active product status. These include IRL1404ZPBF (Infineon HEXFET® series, active status, RoHS3 compliant).

Category B - Functional Substitutes (Enhanced Performance): Parts with higher current ratings, lower on-state resistance, or improved gate charge characteristics. These include IPP023N04LGXKSA1, IPP041N04NGXKSA1, IRLB3034PBF, IXTP220N04T2, and PSMN2R2-40PS,127. These parts exceed the minimum requirements and provide design margin.

Category C - Cross-Manufacturer Alternatives: Parts from manufacturers other than Infineon (Alpha & Omega Semiconductor, Fairchild Semiconductor, IXYS, Nexperia) that meet electrical and package requirements.

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications):

IRL1404ZPBF is the primary direct equivalent. This part maintains identical electrical specifications to the original IRL1404 (40V, 75A, 3.1 mOhm Rds On, 230W power dissipation) while offering active product status and RoHS3 compliance. Inventory availability is 25,300 pieces. This part is suitable for applications requiring exact parameter matching and is recommended for designs currently using the obsolete 64-8016 variant.

For New Designs with Performance Margin:

IPP041N04NGXKSA1 (Infineon OptiMOS™ series, active status) provides 80A continuous drain current with 4.1 mOhm Rds On and reduced gate charge (56 nC). This part exceeds the 75A minimum requirement and offers improved switching characteristics. Inventory: 4,150 pieces. RoHS3 compliant.

IPP023N04NGXKSA1 (Infineon OptiMOS™ series, active status) provides 90A continuous drain current with superior 2.3 mOhm Rds On, enabling lower power dissipation in high-current applications. Inventory: 877 pieces. RoHS3 compliant.

For High-Current Applications:

IXTP220N04T2 (IXYS TrenchT2™ series, active status) provides 220A continuous drain current with 3.5 mOhm Rds On and 360W power dissipation. This part is suitable for applications requiring significant current headroom. Inventory: 4,199 pieces. RoHS3 compliant.

IRLB3034PBF (Infineon HEXFET® series, not for new designs) provides 195A continuous drain current with 1.7 mOhm Rds On and 375W power dissipation. While marked "Not For New Designs," this part remains available (27,400 pieces) for legacy system support.

Compliance Considerations:

All recommended active-status parts are RoHS3 compliant. The original IRL1404 (64-8016) is RoHS non-compliant. For applications subject to RoHS requirements, IRL1404ZPBF or active-status alternatives must be selected.

Obsolete Parts to Avoid for New Designs:

PSMN2R2-40PS,127 and PSMN2R8-40PS,127 (Nexperia) are marked obsolete. IPP039N04LGXKSA1 and IRLB3034PBF are marked "Not For New Designs." These parts should only be used for legacy system maintenance or when new-design alternatives are unavailable.

Frequently Asked Questions (FAQ)

Q1: Can IRL1404ZPBF be used as a direct replacement for the obsolete 64-8016?

A: Yes. IRL1404ZPBF is electrically identical to the original IRL1404 (40V, 75A, 3.1 mOhm Rds On, 230W power dissipation) and uses the same TO-220-3 package. The primary differences are active product status and RoHS3 compliance. No circuit modifications are required.

Q2: What is the difference between the Infineon HEXFET® and OptiMOS™ series substitutes?

A: HEXFET® (IRL1404ZPBF, IRLB3034PBF) represents an older technology platform. OptiMOS™ (IPP023N04NGXKSA1, IPP041N04NGXKSA1) represents a newer platform with improved gate charge characteristics and lower on-state resistance. OptiMOS™ parts are recommended for new designs.

Q3: Why do some substitute parts have lower power dissipation ratings than the original IRL1404?

A: Power dissipation is a function of on-state resistance and current. Parts like IPP039N04LGXKSA1 and IPP041N04NGXKSA1 have lower power dissipation ratings because they are rated for 80A continuous current rather than 75A. At the same current level, lower Rds On values result in lower power dissipation. These parts are still suitable for IRL1404 replacement in 75A applications.

Q4: Can I use a substitute part with higher current rating (e.g., IXTP220N04T2 at 220A) in place of the 75A IRL1404?

A: Yes. Higher current-rated parts are electrically compatible and provide design margin. The 220A IXTP220N04T2 will operate safely in any circuit designed for the 75A IRL1404. The primary considerations are gate drive compatibility and PCB layout. Verify that the gate drive circuit can supply the required gate charge (112 nC for IXTP220N04T2 versus 110 nC for IRL1404).

Q5: Are there package differences between substitute parts?

A: All listed substitute parts use TO-220-3 through-hole packages. Some variants specify TO-220AB (3-pin with larger tab) versus PG-TO220-3 (3-pin standard). These are mechanically compatible in standard TO-220 footprints. Verify PCB pad dimensions if upgrading from older designs.

Q6: Which substitute part offers the best on-state resistance performance?

A: PSMN2R2-40PS,127 (Nexperia) offers the lowest Rds On at 2.1 mOhm @ 25A, 10V. However, this part is obsolete. Among active-status parts, IPP023N04NGXKSA1 offers 2.3 mOhm Rds On, providing superior performance for power-sensitive applications.

Q7: What is the significance of gate charge (Qg) differences between parts?

A: Gate charge affects switching speed and gate drive power requirements. Lower Qg values (e.g., IPP041N04NGXKSA1 at 56 nC) enable faster switching and reduce gate drive losses. Higher Qg values (e.g., FDP8441 at 280 nC) require more gate drive current but may offer other performance benefits. For most applications, Qg differences within the 56–162 nC range are not critical.

Q8: Should I select a substitute based on lowest Rds On or lowest power dissipation?

A: Selection depends on application requirements. For high-frequency switching applications, lower Rds On reduces conduction losses. For linear or low-frequency applications, power dissipation rating is more relevant. Both parameters should be evaluated against your specific thermal and efficiency requirements.

Q9: Are cross-manufacturer substitutes (Alpha & Omega, Fairchild, IXYS, Nexperia) as reliable as Infineon parts?

A: All listed manufacturers are established semiconductor suppliers with equivalent quality standards. Cross-manufacturer substitutes are electrically compatible and meet the same compliance requirements. Selection should be based on availability, cost, and specific performance characteristics rather than manufacturer preference alone.

Q10: What should I verify before implementing a substitute part in production?

A: Verify gate drive voltage compatibility (Vgs Max: ±16V to ±20V across parts), confirm thermal management is adequate for the substitute's power dissipation rating, and validate that PCB layout accommodates any package variant differences. Electrical simulation or bench testing is not required for parts meeting the specified parameter ranges.
