Engineering Selection Recommendations

For Direct Replacement (Obsolete Status Mitigation):

The IRLR014TRPBF (Vishay Siliconix, active status) is the primary substitute for IRLR014NTRPBF. Both devices share identical electrical specifications at rated conditions (60V, 7.7A continuous drain current, 200mOhm on-resistance @ 4.6A/5V). The IRLR014TRPBF is RoHS3 compliant and available in high inventory (17,695 pcs). Operating temperature range is -55°C to 150°C, which covers the majority of industrial applications, though the original part extends to 175°C.

Frequently Asked Questions (FAQ)

Q1: Can IRLR014TRPBF directly replace IRLR014NTRPBF in existing designs?

A: The IRLR014TRPBF is electrically compatible at rated operating conditions. Both are N-Channel MOSFETs in DPAK packages with identical continuous drain current (7.7A) and on-resistance specifications (200mOhm @ 4.6A, 5V). The primary difference is the operating temperature range: IRLR014NTRPBF extends to 175°C while IRLR014TRPBF is rated to 150°C. For applications operating below 150°C, direct substitution is valid. The IRLR014TRPBF is active status with RoHS3 compliance and high inventory availability.

Q2: What is the difference between IRLR014 and IRLR024 series?

A: The IRLR024 series provides higher continuous drain current (14A) compared to IRLR014 (7.7A), both at 60V Vdss. On-resistance is identical at 100mOhm @ 8.4A, 5V for IRLR024 versus 200mOhm @ 4.6A, 5V for IRLR014. Gate charge for IRLR024 is 18nC @ 5V versus 8.4nC @ 5V for IRLR014. Select IRLR024 when load current exceeds 7.7A; select IRLR014 for lower current applications requiring lower gate charge and reduced drive power.

Q3: Why does IRFR020TRR have higher gate charge than IRLR014TRPBF?

A: Gate charge (Qg) is measured at 10V for IRFR020TRR (25nC) versus 5V for IRLR014TRPBF (8.4nC). Higher gate charge reflects the larger die size and higher current capability (14A vs. 7.7A). The IRFR020TRR requires more gate drive energy but delivers superior on-resistance (100mOhm vs. 200mOhm) and higher power dissipation capability (42W vs. 25W).

Q4: Is BUK72150-55A,118 suitable for non-automotive applications?

A: Yes. The BUK72150-55A,118 is AEC-Q101 automotive qualified but functions as a general-purpose N-Channel MOSFET. It maintains 55V Vdss (matching the original IRLR014NTRPBF) and provides 11A continuous drain current. On-resistance is 150mOhm @ 5A, 10V. This part is suitable for any application requiring 55V/11A capability in DPAK packaging, regardless of automotive requirements.

Q5: What packaging options are available for substitute parts?

A: All substitute parts listed maintain TO-252-3 DPAK surface mount packaging for mechanical compatibility. Packaging variants differ by tape/reel configuration: Cut Tape (CT), Tape & Reel (TR), Digi-Reel®, or Tube. These are logistics variants only; electrical and mechanical specifications remain identical. Select packaging based on production volume and assembly equipment compatibility.

Q6: Which substitute part has the best thermal performance?

A: The IRFR020TRR and IRLR024TRLPBF both deliver 42W maximum power dissipation (Tc), compared to 28W for IRLR014NTRPBF and 25W for IRLR014TRPBF. The IRFR020TRR achieves this through the lowest on-resistance (100mOhm @ 8.4A, 10V) and highest current rating (14A). For thermally constrained designs, IRFR020TRR or IRLR024TRLPBF are preferred.

Q7: Are there RoHS compliance differences between substitutes?

A: Yes. IRLR014TRPBF, IRLR024TRLPBF, IRLR014TRLPBF, and IRLR014PBF are RoHS3 compliant. IRFR020TRR, IRLR024TR, IRLR014TR, IRLR014TRL, and IRLR014TRR are RoHS non-compliant. For applications requiring RoHS3 certification, select from the compliant group. The original IRLR014NTRPBF status is not specified in available data.

Q8: What is the maximum operating temperature for each substitute?

A: IRLR014NTRPBF (original) operates to 175°C. Vishay Siliconix IRLR014 and IRLR024 series are rated to 150°C. BUK72150-55A,118 (Nexperia) operates to 175°C, matching the original. IRFR020TRR is rated to 150°C. For applications requiring 175°C operation, select IRLR014NTRPBF (if available) or BUK72150-55A,118.

Q9: How do gate threshold voltages compare across substitutes?

A: IRLR014NTRPBF has Vgs(th) of 1V @ 250µA. Vishay IRLR014 variants specify 2V @ 250µA. IRFR020TRR specifies 4V @ 250µA. BUK72150-55A,118 specifies 4V @ 1mA. Lower threshold voltage (1V) requires less gate drive voltage but may be more susceptible to parasitic turn-on. Higher threshold voltage (4V) provides better noise immunity. Select based on gate drive circuit capability and application noise environment.

Q10: Can IRLR014NTRPBF be used in place of IRLR024 series?

A: No. IRLR014NTRPBF is rated for 10A continuous drain current, while IRLR024 series is rated for 14A. Using IRLR014NTRPBF in an application designed for 14A would result in thermal stress and potential device failure. Conversely, IRLR024 can replace IRLR014 in applications requiring ≤10A, as it provides higher current margin and better thermal performance.
