IRFR024 N-Channel MOSFET 60V 14A DPAK Equivalent & Substitute Parts

Part Overview

The IRFR024 is an N-Channel MOSFET manufactured by Vishay Siliconix in DPAK (TO-252-3) surface mount package. This device operates at 60V drain-source voltage with 14A continuous drain current and is rated for 42W power dissipation at case temperature. The IRFR024 is classified as obsolete product status, necessitating identification of active equivalent and substitute components for new designs and ongoing production support. Substitute parts must maintain electrical compatibility within the specified parameter ranges while offering active product status and current manufacturing availability.

Substitute Part Grouping Explanation

Substitute parts for the IRFR024 are grouped based on electrical parameter compatibility within the following criteria:

Primary Substitution Criteria:

Drain-Source Voltage (Vdss): 55V minimum to 60V maximum
Continuous Drain Current (Id): 11A minimum to 17A maximum
On-State Resistance (Rds On): 75mOhm to 115mOhm range
Package Type: DPAK / TO-252-3 surface mount configuration
Gate-Source Threshold Voltage (Vgs(th)): 2.5V to 4V range
Operating Temperature: -55°C minimum to 150°C minimum

Grouping Logic:

Group 1 (Direct Electrical Equivalents): Parts matching IRFR024 electrical specifications with active product status and RoHS3 compliance
Group 2 (Functional Substitutes - Lower Current Rating): Parts with 60V Vdss but reduced Id rating (11A), suitable for applications with lower current requirements
Group 3 (Functional Substitutes - Enhanced Performance): Parts with 55V Vdss and higher Id rating (17A), offering improved current handling
Group 4 (Alternative Manufacturers): Parts from different manufacturers meeting core electrical parameters in DPAK package

Substitution validity depends on application current requirements, thermal management capability, and compliance requirements.

Engineering Selection Recommendations

Primary Recommendation - Direct Equivalent:

IRFR024PBF (Vishay Siliconix) is the direct electrical and mechanical equivalent to the obsolete IRFR024. This part maintains identical electrical specifications (60V, 14A, 100mOhm Rds On) with active product status and RoHS3 compliance. Packaging is identical DPAK (TO-252-3). This is the preferred substitute for direct replacement in existing designs.

Secondary Recommendation - Enhanced Performance:

IRFR024NTRPBF (Infineon Technologies) offers improved specifications with 17A continuous drain current, 75mOhm Rds On, and extended operating temperature to 175°C. Vdss is reduced to 55V, which remains compatible with 60V-rated applications. This part is active and RoHS3 compliant. Selection is appropriate for applications requiring higher current capacity or extended thermal operating range.

Alternative Recommendation - Reduced Current Applications:

For applications requiring less than 14A continuous drain current, FQD13N06LTM (onsemi) or RFD3055LESM9A (onsemi) provide 11A rating at 60V with active status and RoHS3 compliance. These parts reduce thermal stress in lower-current circuits while maintaining voltage compatibility.

Compliance Consideration:

All recommended substitutes carry RoHS3 compliance status, addressing environmental and regulatory requirements absent in the obsolete IRFR024. Selection should prioritize active product status to ensure long-term manufacturing availability and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can IRFR024PBF directly replace IRFR024 in existing PCB designs?

A: Yes. IRFR024PBF is electrically and mechanically identical to IRFR024, with identical DPAK package pinout and electrical specifications. No circuit modifications are required. The primary difference is active product status and RoHS3 compliance.

Q: What is the difference between IRFR024NTRLPBF and IRFR024NTRPBF?

A: Both are Infineon HEXFET devices with identical electrical specifications (55V, 17A, 75mOhm Rds On). IRFR024NTRLPBF is classified as "Not For New Designs" with limited inventory (2250 pcs). IRFR024NTRPBF is active product with significantly higher inventory (205200 pcs). For new designs, IRFR024NTRPBF is the appropriate selection.

Q: Can I use FQD13N06LTM as a substitute if my application requires 14A continuous current?

A: No. FQD13N06LTM is rated for 11A continuous drain current, which is below the IRFR024 specification of 14A. Using this part in a 14A application would exceed device ratings and create reliability risk. Select parts with minimum 14A rating or verify application current requirements are below 11A.

Q: Are all substitute parts available in the same DPAK package?

A: Yes. All listed substitute parts use DPAK (TO-252-3) surface mount package, ensuring mechanical compatibility with existing PCB layouts. Package designation may vary slightly (TO-252AA, SC-63) but all refer to the same physical form factor.

Q: What is the significance of the operating temperature range difference between IRFR024 (150°C) and IRFR024NTRPBF (175°C)?

A: The extended temperature range in IRFR024NTRPBF (175°C vs 150°C) allows operation in higher thermal environments. For applications operating within -55°C to 150°C range, both parts are functionally equivalent. Applications requiring operation above 150°C junction temperature require IRFR024NTRPBF or similar extended-range alternatives.

Q: Why does RSD050N06TL have lower current rating (5A) than IRFR024 (14A)?

A: RSD050N06TL is designed for lower-current applications and is not a direct substitute for IRFR024. This part is listed as a functional alternative only for circuits with maximum 5A continuous drain current requirements. Attempting to use this part in 14A applications violates device ratings.

Q: What does "Not For New Designs" status mean for IRFR024NTRLPBF?

A: "Not For New Designs" indicates the manufacturer (Infineon) recommends against using this part in new product development. While the part remains available, it may have limited future support and manufacturing commitment. For new designs, select IRFR024NTRPBF (active status) or IRFR024PBF instead.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry RoHS3 compliance status. The original IRFR024 is RoHS non-compliant. Substitution to any recommended part automatically addresses RoHS compliance requirements for new production.

Q: Can I mix IRFR024 and IRFR024PBF in the same production batch?

A: While electrically identical, mixing obsolete (IRFR024) and active (IRFR024PBF) parts in production is not recommended. Standardize on IRFR024PBF for all new manufacturing to ensure consistent supply chain management and compliance status across production lots.
