Engineering Selection Recommendations

Primary Recommendation – Infineon Direct Replacement:

IRLR024NTRPBF is the preferred substitute. This part is manufactured by the same supplier as the original IRLR024ZTRPBF, maintains identical Vdss (55V) and compatible drain current (17A vs. 16A), and carries Active product status. The IRLR024NTRPBF is ROHS3 Compliant and REACH Unaffected, providing regulatory compliance advantages over the obsolete original. Inventory availability is substantial (77,400 units), ensuring supply chain continuity.

Secondary Recommendations – Cross-Manufacturer Alternatives:

STMicroelectronics STD16NF06LT4 and STD20NF06LT4 series parts are suitable alternatives. Both maintain 60V Vdss (exceeding the 55V requirement), support 24A continuous drain current (exceeding 16A requirement), and are rated for -55°C to 175°C operating temperature, matching the original specification. STD20NF06LT4 offers superior power dissipation (60W vs. 35W), providing thermal margin. Both parts are ROHS3 Compliant and carry Active product status.

Tertiary Recommendations – Vishay Siliconix Base Series:

IRLR024, IRLR024TR, IRLR024TRL, and IRLR024TRR are functionally equivalent variants from Vishay Siliconix. These parts support 60V Vdss and 14A continuous drain current. While drain current is lower than the original 16A specification, these parts are suitable for applications where the actual operating current does not exceed 14A. All variants carry Active product status and are available in quantity.

Compliance Considerations:

The original IRLR024ZTRPBF carries no RoHS compliance designation. IRLR024NTRPBF (ROHS3 Compliant), STD16NF06LT4 (ROHS3 Compliant), STD20NF06LT4 (ROHS3 Compliant), and STD20NF06T4 (ROHS3 Compliant) provide regulatory compliance for new designs. All substitute parts maintain MSL 1 (Unlimited) moisture sensitivity rating and REACH Unaffected status where specified.

Frequently Asked Questions (FAQ)

Q1: Can IRLR024NTRPBF directly replace IRLR024ZTRPBF without circuit modification?

A: Yes. IRLR024NTRPBF is a direct Infineon replacement with identical Vdss (55V), compatible drain current (17A vs. 16A), and identical package (TO-252-3 DPAK). Gate threshold voltage is lower (2V vs. 3V), which is compatible with standard gate drive circuits. No circuit modification is required.

Q2: What is the difference between STD16NF06LT4 and STD20NF06LT4?

A: Both parts are STMicroelectronics STripFET™ II series MOSFETs with 60V Vdss and 24A drain current. The primary difference is on-state resistance: STD16NF06LT4 has 70 mOhm (@ 8A, 10V), while STD20NF06LT4 has 40 mOhm (@ 12A, 10V). STD20NF06LT4 offers lower conduction losses and higher power dissipation capability (60W vs. 40W). Selection depends on thermal and efficiency requirements.

Q3: Are Vishay Siliconix IRLR024 variants suitable for 16A continuous operation?

A: Vishay Siliconix IRLR024, IRLR024TR, IRLR024TRL, and IRLR024TRR are rated for 14A continuous drain current at 25°C. These parts are suitable only if actual circuit operating current does not exceed 14A. For applications requiring sustained 16A operation, IRLR024NTRPBF or STMicroelectronics alternatives (STD16NF06LT4, STD20NF06LT4, STD20NF06T4) are required.

Q4: What is the significance of the operating temperature range difference between parts?

A: IRLR024ZTRPBF and IRLR024NTRPBF support -55°C to 175°C. FQD20N06TM, IRLR024, IRLR024TR, IRLR024TRL, and IRLR024TRR support -55°C to 150°C. STMicroelectronics parts (STD16NF06LT4, STD20NF06LT4, STD20NF06T4) support -55°C to 175°C. For applications requiring operation above 150°C, select parts with 175°C maximum junction temperature rating.

Q5: How does on-state resistance (Rds On) affect part selection?

A: Lower Rds On reduces conduction losses and heat generation. IRLR024ZTRPBF has 58 mOhm, IRLR024NTRPBF has 65 mOhm, STD20NF06LT4 has 40 mOhm, and Vishay IRLR024 variants have 100 mOhm. For high-current or high-frequency applications, lower Rds On values (STD20NF06LT4 at 40 mOhm) provide superior thermal performance. For lower-current applications, higher Rds On values are acceptable.

Q6: Are all substitute parts available in the same packaging?

A: Yes. All substitute parts listed are available in TO-252-3 DPAK (2 Leads + Tab) Surface Mount package, ensuring mechanical and thermal compatibility with the original IRLR024ZTRPBF. PCB layout and thermal management design do not require modification.

Q7: What is the inventory status of substitute parts?

A: IRLR024NTRPBF has 77,400 units in stock. STD20NF06T4 has 27,055 units. STD16NF06LT4 has 17,100 units. STD20NF06LT4 has 2,220 units. Vishay IRLR024 variants have between 987 and 15,998 units. IRLR024NTRPBF and STMicroelectronics parts provide the highest supply availability.

Q8: Which substitute part offers the best regulatory compliance for new designs?

A: IRLR024NTRPBF, STD16NF06LT4, STD20NF06LT4, and STD20NF06T4 are all ROHS3 Compliant. IRLR024NTRPBF is the preferred choice for Infineon-based designs. STMicroelectronics alternatives are preferred for designs requiring higher current capacity (24A) or lower on-state resistance.
