IRFL014TR N-Channel 60V 2.7A MOSFET Equivalent & Substitute Parts

Part Overview

The IRFL014TR is an N-Channel MOSFET manufactured by Vishay Siliconix, rated for 60V drain-to-source voltage with 2.7A continuous drain current in a surface mount SOT-223 package. This device is classified as obsolete, necessitating identification of active equivalent and substitute components for new designs and production continuity. Equivalent parts maintain identical or superior electrical performance within the same package footprint, while substitute parts provide functional alternatives with minor parameter variations acceptable for the application.

Substitute Part Grouping Explanation

Substitution of the IRFL014TR is determined by the following critical parameters: drain-to-source voltage rating (Vdss), continuous drain current capability (Id), on-state resistance (Rds On), package type (SOT-223), and mounting configuration (surface mount). All identified substitutes maintain the 60V Vdss rating and SOT-223 package footprint, ensuring mechanical and electrical compatibility at the circuit board level.

Substitutes are grouped into two categories:

Parametric Equivalents: Parts with identical or superior electrical specifications across all measured parameters, including Vdss, Id, Rds On, and thermal characteristics. These parts are direct functional replacements.

Functional Alternatives: Parts with Vdss and Id ratings that meet or exceed the original specification, with acceptable variations in secondary parameters such as gate charge, input capacitance, and threshold voltage. These parts are suitable for applications where the primary electrical requirements are satisfied.

Engineering Selection Recommendations

IRFL014TRPBF (Vishay Siliconix): This part is the direct parametric equivalent of the IRFL014TR, maintaining identical electrical specifications across all measured parameters. The IRFL014TRPBF is active in production status and ROHS3 compliant, making it the primary choice for direct replacement in new designs and production continuity. The only distinction is packaging format (Tape & Reel versus bulk), which does not affect electrical performance.

NDT014 (onsemi): This part provides functional equivalence with identical Vdss (60V) and Id (2.7A) ratings, matching the original specification exactly. The NDT014 is active in production, ROHS3 compliant, and offers extended operating temperature range (-65°C to 150°C). The SOT-223-4 package variant is mechanically compatible with the original SOT-223 footprint. This part is suitable for applications requiring active component sourcing from alternative manufacturers.

NDT014L (onsemi): This part exceeds the original specification with 2.8A continuous drain current and improved on-state resistance (160 mOhm at 3.4A, 10V). The NDT014L is active in production, ROHS3 compliant, and provides enhanced thermal performance with 3W power dissipation rating. This part is suitable for applications requiring improved current handling or reduced thermal dissipation.

NDT3055L (onsemi): This part provides enhanced current capability (4A continuous drain current) with superior on-state resistance (100 mOhm at 4A, 10V). The NDT3055L is active in production, ROHS3 compliant, and maintains the 60V Vdss rating. This part is suitable for applications requiring higher current capacity or lower conduction losses.

STN3NF06L (STMicroelectronics): This part provides enhanced current capability (4A continuous drain current) with superior on-state resistance (100 mOhm at 1.5A, 10V). The STN3NF06L is active in production, ROHS3 compliant, and is part of the STripFET™ II series. This part is suitable for applications requiring higher current capacity or lower conduction losses, with the advantage of extended inventory availability (72,446 units in stock).

IRFL014NTRPBF (Infineon Technologies): This part provides reduced Vdss rating (55V) and lower continuous drain current (1.9A) compared to the original specification. The IRFL014NTRPBF is active in production and ROHS3 compliant. This part is suitable only for applications where the reduced voltage and current ratings are acceptable, and should not be used as a direct replacement in circuits designed for the full 60V/2.7A specification.

Frequently Asked Questions (FAQ)

Q: Can IRFL014TRPBF be used as a direct replacement for IRFL014TR?

A: Yes. The IRFL014TRPBF is a parametric equivalent with identical electrical specifications. The only difference is packaging format (Tape & Reel). Both parts maintain the same SOT-223 package footprint, electrical performance, and thermal characteristics. The IRFL014TRPBF is active in production and ROHS3 compliant, making it the recommended replacement for obsolete IRFL014TR inventory.

Q: What is the difference between SOT-223 and SOT-223-4 packages?

A: Both package designations refer to the same physical footprint and pin configuration used in this product category. The "-4" designation in SOT-223-4 explicitly indicates the four-pin configuration (Gate, Drain, Source, Source). All parts listed in this reference maintain mechanical compatibility with the original SOT-223 footprint.

Q: Can NDT3055L or STN3NF06L be used in place of IRFL014TR?

A: Yes, with design verification. Both parts exceed the original specification with 4A continuous drain current and superior on-state resistance (100 mOhm). These parts are suitable for applications where the original 2.7A specification is a design margin, and the enhanced performance provides additional headroom. Circuit validation is required to confirm compatibility with gate drive voltage and thermal management design.

Q: Why does IRFL014NTRPBF have lower current and voltage ratings?

A: The IRFL014NTRPBF is manufactured by Infineon Technologies and is rated for 55V Vdss and 1.9A continuous drain current. This part does not meet the full specification of the original IRFL014TR (60V/2.7A) and should not be used as a direct replacement in circuits designed for the higher ratings. This part is suitable only for applications with reduced voltage and current requirements.

Q: What is the inventory status of available substitutes?

A: Current inventory levels are as follows: IRFL014TRPBF (25,200 units), IRFL014NTRPBF (35,100 units), NDT014 (40,800 units), NDT014L (40,900 units), NDT3055L (23,100 units), and STN3NF06L (72,446 units). STN3NF06L offers the highest inventory availability among active substitutes.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All active substitute parts listed in this reference are ROHS3 compliant. The original IRFL014TR is RoHS non-compliant. For applications requiring RoHS compliance, any of the listed active substitutes are acceptable from a regulatory standpoint.

Q: What is the thermal performance difference between substitute parts?

A: Power dissipation ratings vary: IRFL014TRPBF (2W Ta, 3.1W Tc), IRFL014NTRPBF (1W Ta), NDT014 (3W Ta), NDT014L (3W Ta), NDT3055L (3W Ta), and STN3NF06L (3.3W Tc). Parts with higher power dissipation ratings provide greater thermal margin in applications with sustained current flow. On-state resistance values determine conduction losses; lower Rds On values reduce heat generation at equivalent current levels.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes, all parts maintain the SOT-223 package footprint and pin configuration. PCB layout modifications are not required. However, circuit validation is recommended for applications operating at the upper limits of the original specification (60V, 2.7A) to confirm that substitute parts with different gate charge, threshold voltage, or input capacitance values do not affect gate drive circuit performance or switching characteristics.
