Engineering Selection Recommendations

Parametric Equivalent (Direct Replacement):

The IRLR024NTRPBF (Infineon Technologies) is the recommended parametric equivalent. It maintains identical electrical specifications (55V, 17A, 65mOhm Rds On) and thermal performance (45W) while offering Active product status. This part is ROHS3 compliant and carries MSL Level 1 rating, matching the original device's environmental qualifications.

Functional Substitutes for Active Designs:

For applications requiring active product support and RoHS3 compliance, the following substitutes are qualified:

NTD18N06LT4G (onsemi): Exceeds current rating (18A vs. 17A) with equivalent on-resistance (65mOhm) and maintains full temperature range (-55°C to 175°C). ROHS3 compliant. Suitable for designs requiring higher current margin.

STD20NF06LT4 (STMicroelectronics): Provides superior on-resistance (40mOhm vs. 65mOhm) and higher current capacity (24A vs. 17A) with increased power dissipation capability (60W vs. 45W). ROHS3 compliant and full temperature range support. Recommended for thermally demanding applications.

STD16NF06LT4 (STMicroelectronics): Offers higher current capacity (24A) with comparable on-resistance (70mOhm) and full temperature range support. ROHS3 compliant. Suitable for general-purpose substitution.

Substitutes with Compliance Limitations:

The Vishay Siliconix IRLR024 variants (IRLR024, IRLR024TR, IRLR024TRL, IRLR024TRR) are Active products but carry RoHS non-compliant status. These are suitable only for applications where RoHS compliance is not required. Current rating is lower (14A vs. 17A) and on-resistance is higher (100mOhm vs. 65mOhm).

Limited Substitutes:

AOD444 (Alpha & Omega Semiconductor) and DMN6068LK3-13 (Diodes Incorporated) have reduced current ratings (12A and 6A respectively) relative to the original 17A specification. These are suitable only for applications with lower current requirements.

Frequently Asked Questions (FAQ)

Q1: Can IRLR024NTRPBF be used as a direct replacement for IRLR024NTRLPBF?

A: Yes. The IRLR024NTRPBF is a parametric equivalent with identical electrical and thermal specifications. The only difference is product status (Active vs. Not For New Designs). Both devices are ROHS3 compliant, carry MSL Level 1 rating, and are packaged in TO-252-3 (DPAK).

Q2: What is the primary difference between the main part and its substitutes?

A: The IRLR024NTRLPBF is rated for 55V Vdss and 17A continuous drain current. Most substitutes operate at 60V Vdss with varying current ratings (6A to 24A). Substitutes with higher current ratings provide design margin; those with lower ratings are suitable only for reduced-current applications.

Q3: Are all substitute parts ROHS3 compliant?

A: No. The Infineon IRLR024NTRPBF, onsemi NTD18N06LT4G, and STMicroelectronics STD16NF06LT4 and STD20NF06LT4 are ROHS3 compliant. The Vishay Siliconix IRLR024 variants are RoHS non-compliant. AOD444 and DMN6068LK3-13 are ROHS3 compliant.

Q4: Which substitute offers the best on-resistance performance?

A: STD20NF06LT4 (STMicroelectronics) provides the lowest on-resistance at 40mOhm @ 12A, 10V, compared to 65mOhm for the original part. This reduces power dissipation in switching applications.

Q5: Can I use a substitute with lower current rating?

A: Substitutes with lower current ratings (AOD444 at 12A, DMN6068LK3-13 at 6A) are suitable only if your application's actual current demand is below the substitute's rating. The original 17A specification must not be exceeded.

Q6: What is the temperature range limitation for certain substitutes?

A: Vishay Siliconix IRLR024 variants and DMN6068LK3-13 support -55°C to 150°C, while the original part and most other substitutes support -55°C to 175°C. Applications requiring operation above 150°C must use parts with extended temperature range.

Q7: Are packaging dimensions identical across all substitutes?

A: All substitutes use TO-252-3 (DPAK) or TO-252 (DPAK) Surface Mount packages with identical lead configurations (2 Leads + Tab, SC-63). Physical footprints are compatible for PCB layout purposes.

Q8: Which substitute is recommended for new designs?

A: For new designs requiring RoHS3 compliance and full temperature range support, STD20NF06LT4 (STMicroelectronics) is recommended. It provides superior electrical performance, active product status, and comprehensive environmental certifications.

Q9: What does "Not For New Designs" status mean?

A: This indicates the IRLR024NTRLPBF is end-of-life. While existing inventory may be available, the manufacturer does not recommend its use in new product designs. Active substitutes should be selected for new applications.

Q10: How do I verify compatibility before substitution?

A: Confirm that the substitute's Vdss rating meets or exceeds your circuit's maximum voltage, the Id rating meets or exceeds your application's continuous current, and the package type matches your PCB layout. Verify RoHS and temperature range requirements against your design specifications.
