Engineering Selection Recommendations

Direct Replacement (Recommended for Obsolete Part Substitution):

IRL1004PBF is the primary substitute for IRL1004. Both devices share identical electrical specifications and TO-220AB packaging. IRL1004PBF carries Active product status and RoHS3 compliance, addressing the obsolescence of the original IRL1004. This substitution requires no circuit modifications and maintains full electrical compatibility.

Higher Current Capability Substitutes:

IRLB3034PBF provides 195A continuous drain current, exceeding the IRL1004 specification by 50%. This device maintains 40V Vdss rating and TO-220AB packaging. IRLB3034PBF is classified as Not For New Designs but remains available in inventory. The reduced on-state resistance (1.7 mOhm vs. 6.5 mOhm) results in lower power dissipation and improved thermal performance. This substitute is suitable for applications requiring additional current margin or thermal headroom without circuit redesign.

PSMN2R2-40PS,127 (Nexperia) provides 100A continuous drain current with superior on-state resistance (2.1 mOhm). This device is obsolete but maintains TO-220AB compatibility. The lower Rds On reduces conduction losses compared to IRL1004.

Reduced Current Capability Substitutes:

IRL1404ZPBF provides 75A continuous drain current, representing a 42% reduction from IRL1004 specification. This device is Active and RoHS3 compliant. IRL1404ZPBF is suitable only for applications with confirmed current requirements below 75A and should not be used in designs requiring the full 130A capability of IRL1004.

IPP039N04LGXKSA1 (Infineon OptiMOS™) provides 80A continuous drain current with improved on-state resistance (3.9 mOhm). This device is Not For New Designs and features reduced power dissipation (94W vs. 200W). Suitable for lower-current applications only.

STP95N4F3 (STMicroelectronics STripFET™ III) provides 80A continuous drain current with Active product status. This device maintains 40V Vdss and TO-220-3 packaging. Suitable for applications with current requirements below 100A.

Cross-Manufacturer Alternative:

CSD18504KCS (Texas Instruments NexFET™) provides 100A continuous drain current (Tc) with Active product status and RoHS3 compliance. This device features significantly reduced gate charge (25 nC vs. 100 nC), enabling faster switching characteristics. CSD18504KCS is suitable for applications where switching speed is critical and current requirements do not exceed 100A. Operating temperature range is limited to -55°C to 150°C compared to 175°C for IRL1004.

Compliance and Availability:

All recommended substitutes maintain RoHS3 compliance except where noted as Not For New Designs. Infineon-manufactured substitutes (IRL1004PBF, IRLB3034PBF, IRL1404ZPBF) preserve design continuity within the HEXFET® series. Cross-manufacturer alternatives (CSD18504KCS, STP95N4F3) provide equivalent electrical performance with different thermal and switching characteristics.

Frequently Asked Questions (FAQ)

Q: Can IRL1004PBF be used as a direct replacement for IRL1004?

A: Yes. IRL1004PBF is the direct equivalent with identical electrical specifications (40V, 130A, 6.5 mOhm Rds On, 200W power dissipation) and TO-220AB packaging. The primary difference is product status (Active vs. Obsolete) and RoHS3 compliance. No circuit modifications are required.

Q: What is the difference between IRL1004 and IRLB3034PBF?

A: IRLB3034PBF provides higher current capability (195A vs. 130A) and lower on-state resistance (1.7 mOhm vs. 6.5 mOhm), resulting in reduced power dissipation and improved thermal performance. Both devices maintain 40V Vdss rating and TO-220AB packaging. IRLB3034PBF is suitable for applications requiring additional current margin. IRLB3034PBF is classified as Not For New Designs.

Q: Can I use IRL1404ZPBF in place of IRL1004?

A: IRL1404ZPBF is not recommended as a direct substitute. This device provides only 75A continuous drain current, representing a 42% reduction from the IRL1004 specification of 130A. Use IRL1404ZPBF only in applications with confirmed current requirements below 75A. IRL1404ZPBF is Active and RoHS3 compliant.

Q: What are the advantages of CSD18504KCS over IRL1004?

A: CSD18504KCS (Texas Instruments) provides significantly reduced gate charge (25 nC vs. 100 nC), enabling faster switching characteristics and reduced gate drive power requirements. CSD18504KCS is Active and RoHS3 compliant. However, CSD18504KCS provides only 100A continuous drain current and has a lower maximum operating temperature (150°C vs. 175°C). Use CSD18504KCS in applications where switching speed is critical and current requirements do not exceed 100A.

Q: Are Nexperia PSMN series devices suitable substitutes?

A: PSMN2R2-40PS,127 and PSMN4R5-40PS,127 provide 100A continuous drain current with TO-220AB packaging and 40V Vdss rating. Both devices are obsolete. PSMN2R2-40PS,127 features superior on-state resistance (2.1 mOhm), while PSMN4R5-40PS,127 provides lower gate charge (42.3 nC). These devices are suitable for applications with current requirements below 130A. PSMN8R0-40PS,127 provides only 77A and is not recommended for designs requiring 130A capability.

Q: What is the operating temperature range difference between IRL1004 and CSD18504KCS?

A: IRL1004 operates from -55°C to 175°C (TJ), while CSD18504KCS operates from -55°C to 150°C (TJ). CSD18504KCS has a 25°C lower maximum junction temperature. Verify that your application does not require operation above 150°C before selecting CSD18504KCS.

Q: Can I use STP95N4F3 as a substitute for IRL1004?

A: STP95N4F3 provides 80A continuous drain current, representing a 38% reduction from IRL1004 specification. STP95N4F3 is Active and RoHS3 compliant with 40V Vdss rating and TO-220-3 packaging. Use STP95N4F3 only in applications with confirmed current requirements below 80A. This device is not suitable for designs requiring the full 130A capability of IRL1004.

Q: What packaging options are available for IRL1004 substitutes?

A: Most substitutes maintain TO-220AB or TO-220-3 through-hole packaging, preserving mechanical compatibility with existing PCB layouts. IRL1004PBF, IRLB3034PBF, IRL1404ZPBF, PSMN2R2-40PS,127, PSMN4R5-40PS,127, and PSMN8R0-40PS,127 use TO-220AB. IPP039N04LGXKSA1, CSD18504KCS, and STP95N4F3 use TO-220-3. Both package variants are mechanically compatible with standard TO-220 footprints.

Q: Which substitute offers the best thermal performance?

A: IRLB3034PBF provides the highest power dissipation rating (375W vs. 200W) and lowest on-state resistance (1.7 mOhm vs. 6.5 mOhm), resulting in superior thermal performance. PSMN2R2-40PS,127 also provides excellent thermal characteristics with 306W power dissipation and 2.1 mOhm Rds On. Both devices are suitable for high-current applications requiring minimal thermal rise.

Q: Are all substitutes RoHS3 compliant?

A: IRL1004PBF, IRLB3034PBF, IRL1404ZPBF, CSD18504KCS, PSMN2R2-40PS,127, PSMN4R5-40PS,127, PSMN8R0-40PS,127, and STP95N4F3 are all RoHS3 compliant. IPP039N04LGXKSA1 is also RoHS3 compliant. All substitutes meet current environmental compliance requirements.
