IRLR024NTRL N-Channel 55V 17A MOSFET Equivalent & Substitute Parts

Part Overview

The IRLR024NTRL is an N-Channel MOSFET manufactured by Infineon Technologies, rated for 55V drain-to-source voltage and 17A continuous drain current in a Surface Mount TO-252AA (DPAK) package. This device is classified as Obsolete product status. Due to its obsolescence, equivalent and substitute parts from active product lines are necessary for ongoing design support, production continuity, and long-term component availability.

Substitute Part Grouping Explanation

Substitute parts for the IRLR024NTRL are classified into two categories based on electrical and mechanical compatibility:

Category 1: Parametric Equivalents (Identical Electrical Specifications)

Parametric equivalents maintain all critical electrical parameters within the same tolerance ranges as the original part. These parts are direct functional replacements with identical Vdss (55V or higher), comparable Id ratings, matching Rds On characteristics, and equivalent thermal performance. The primary distinction is packaging format (Cut Tape vs. Tape & Reel) and product status (Active vs. Obsolete).

Key parameters for equivalence:

Drain-to-Source Voltage (Vdss): 55V minimum
Continuous Drain Current (Id): 17A or higher
On-State Resistance (Rds On): 65mOhm or lower @ specified conditions
Gate Charge (Qg): 15nC or lower
Power Dissipation: 45W or higher
Package: TO-252-3 (DPAK)
Operating Temperature: -55°C to 175°C

Category 2: Functional Substitutes (Enhanced or Comparable Specifications)

Functional substitutes provide equivalent or superior electrical performance with minor parameter variations. These parts may have higher voltage ratings, improved current handling, lower on-state resistance, or enhanced thermal characteristics. They are suitable for applications where the original part specifications can accommodate parameter variations without performance degradation.

Key parameters for functional substitution:

Drain-to-Source Voltage (Vdss): 60V (5V higher than original)
Continuous Drain Current (Id): 12A to 25A range
On-State Resistance (Rds On): 40mOhm to 100mOhm
Gate Charge (Qg): 7.5nC to 18nC
Power Dissipation: 20W to 60W
Package: TO-252-3 (DPAK)
Operating Temperature: -55°C to 175°C

Engineering Selection Recommendations

Primary Recommendation: IRLR024NTRPBF

The IRLR024NTRPBF is the direct parametric equivalent of the obsolete IRLR024NTRL. It maintains identical electrical specifications across all critical parameters: 55V Vdss, 17A continuous drain current, 65mOhm Rds On, 15nC gate charge, and 45W power dissipation. The primary advantage is Active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment. Packaging is Cut Tape & Digi-Reel® format. This part requires no circuit redesign and provides 100% functional compatibility.

Secondary Recommendation: STD20NF06LT4

The STD20NF06LT4 from STMicroelectronics (STripFET™ II series) is suitable for applications where enhanced performance is acceptable. It provides 60V Vdss (5V higher rating margin), 24A continuous drain current (7A higher than original), and 40mOhm Rds On (25mOhm lower, improving efficiency). Power dissipation is 60W (15W higher thermal capability). Operating temperature range extends to 175°C (matching original). ROHS3 compliance and Active status ensure supply continuity. This part is recommended for new designs or applications requiring improved thermal performance.

Tertiary Recommendation: DMNH6042SK3-13

The DMNH6042SK3-13 from Diodes Incorporated offers the highest current rating (25A) and lowest on-state resistance (50mOhm @ 6A, 10V) among substitutes. It includes AEC-Q101 automotive qualification, suitable for automotive and industrial applications. The 60V Vdss rating provides adequate margin. Gate charge is 8.8nC (lower switching losses). ROHS3 compliance and Active status are confirmed. This part is recommended for high-current applications or designs requiring automotive-grade reliability.

Compliance Considerations:

IRLR024NTRL and IRLR024 variants are RoHS non-compliant; use IRLR024NTRPBF, STD16NF06LT4, STD20NF06LT4, STD20NF06T4, or DMNH6042SK3-13 for RoHS3-compliant designs.
All recommended substitutes maintain MSL 1 (Unlimited) moisture sensitivity level.
All parts are EAR99 export classification and REACH Unaffected.

Frequently Asked Questions (FAQ)

Q1: Can IRLR024NTRPBF be used as a direct replacement for IRLR024NTRL?

Yes. IRLR024NTRPBF is the parametric equivalent with identical electrical specifications. The only differences are packaging format (Cut Tape & Digi-Reel® vs. Tape & Reel) and product status (Active vs. Obsolete). No circuit modifications are required. RoHS3 compliance is an additional benefit for new designs.

Q2: What is the key difference between IRLR024NTRL and the Vishay IRLR024 variants?

The Infineon IRLR024NTRL is rated for 55V Vdss and 17A Id, while Vishay IRLR024, IRLR024TR, IRLR024TRL, and IRLR024TRR are rated for 60V Vdss and 14A Id. The Infineon part has lower on-state resistance (65mOhm vs. 100mOhm) and higher current rating. Vishay variants have lower operating temperature maximum (150°C vs. 175°C). Both are RoHS non-compliant.

Q3: Why is STD20NF06LT4 recommended over STD16NF06LT4?

STD20NF06LT4 provides superior on-state resistance (40mOhm vs. 70mOhm) and higher power dissipation capability (60W vs. 40W). For applications requiring lower conduction losses and better thermal performance, STD20NF06LT4 is the preferred choice. Both are ROHS3 compliant and rated for 60V/24A.

Q4: Is DMNH6042SK3-13 suitable for non-automotive applications?

Yes. Although DMNH6042SK3-13 carries AEC-Q101 automotive qualification, it is suitable for any application requiring its electrical specifications. The automotive qualification indicates higher reliability and stricter manufacturing controls, making it acceptable for industrial, consumer, and other non-automotive applications.

Q5: What packaging formats are available for these substitutes?

IRLR024NTRPBF is available in Cut Tape & Digi-Reel® format. STD16NF06LT4, STD20NF06LT4, and STD20NF06T4 are available in Cut Tape & Digi-Reel® format. DMNH6042SK3-13 is available in Tape & Reel format. All use TO-252-3 (DPAK) surface mount package with identical pinout and footprint compatibility.

Q6: Are there inventory considerations when selecting a substitute?

Yes. IRLR024NTRPBF has 77,400 pcs in stock (highest availability). STD20NF06T4 has 27,055 pcs. STD16NF06LT4 has 17,100 pcs. STD20NF06LT4 has 2,220 pcs (limited). DMNH6042SK3-13 has 1,088 pcs (limited). For high-volume production, IRLR024NTRPBF or STD20NF06T4 are recommended.

Q7: What is the operating temperature difference between IRLR024NTRL and Vishay IRLR024 variants?

IRLR024NTRL operates from -55°C to 175°C (TJ). Vishay IRLR024, IRLR024TR, IRLR024TRL, and IRLR024TRR operate from -55°C to 150°C (TJ). For applications requiring 175°C maximum junction temperature, use Infineon IRLR024NTRPBF, STMicroelectronics STD series, or Diodes DMNH6042SK3-13.

Q8: How do gate charge differences affect circuit design?

Gate charge (Qg) determines switching speed and driver requirements. IRLR024NTRL has 15nC @ 5V. STD16NF06LT4 has 7.5nC (faster switching, lower driver stress). STD20NF06T4 has 31nC (slower switching, higher driver stress). For high-frequency switching applications, lower Qg is preferred. Verify gate driver capability before substitution.

Q9: Can these parts be used in parallel for higher current applications?

Parallel operation is not recommended without detailed thermal and current-sharing analysis. On-state resistance variations between parts and temperature gradients create unequal current distribution. If higher current is required, select a single part with adequate current rating (e.g., DMNH6042SK3-13 at 25A) rather than paralleling lower-rated devices.

Q10: What compliance certifications are critical for my application?

For RoHS-regulated markets, use ROHS3-compliant parts: IRLR024NTRPBF, STD16NF06LT4, STD20NF06LT4, STD20NF06T4, or DMNH6042SK3-13. For automotive applications, DMNH6042SK3-13 with AEC-Q101 qualification is recommended. All parts are EAR99 export classification and REACH Unaffected. Verify specific regulatory requirements for your end application.
