Substitute Part Grouping Explanation

Substitution of the IRLR014NTR is determined by the following critical parameters:

Primary Compatibility Criteria:

Drain-to-Source Voltage (Vdss): Substitute must equal or exceed 55V
Package Type: Must be TO-252-3 DPAK (2 Leads + Tab) for mechanical and thermal compatibility
Mounting Type: Surface mount configuration required
Continuous Drain Current (Id): Substitute must support minimum 10A at 25°C
On-Resistance (Rds On): Lower or equivalent values ensure thermal performance
Operating Temperature Range: Must span -55°C to 175°C minimum

Substitution Logic: Parts are grouped into two categories based on voltage rating alignment and current capability:

Category A - Direct Voltage Match (55V Rating): BUK72150-55A,118 provides equivalent 55V Vdss with enhanced current capability (11A) and improved power dissipation (36W). This part maintains the same voltage class while offering superior thermal characteristics.

Category B - Voltage Derating (60V+ Rating): IRLR014PBF, IRLR014TR, IRLR014TRL, IRLR014TRLPBF, and IRLR014TRR operate at 60V Vdss, providing 9% voltage margin above the original 55V specification. These parts are electrically compatible in circuits designed for 55V operation. Current rating is reduced to 7.7A, requiring circuit evaluation for applications demanding the full 10A specification.

Category C - Higher Voltage Derating (100V Rating): STD6NF10T4 operates at 100V Vdss with 6A continuous current, suitable only for circuits where higher voltage margin is required and current demand does not exceed 6A.

Category D - Voltage Match with Enhanced Performance (60V Rating): STD12NF06T4 provides 60V Vdss with 12A continuous current and superior on-resistance (100mOhm @ 6A, 10V), offering enhanced current handling for applications requiring higher current capacity within the same voltage class.

Q2: What is the difference between IRLR014TR, IRLR014TRL, IRLR014TRLPBF, IRLR014TRPBF, and IRLR014TRR?

All five variants are based on the IRLR014 base product from Vishay Siliconix and share identical electrical specifications: 60V Vdss, 7.7A continuous current, 200 mOhm on-resistance, and -55°C to 150°C operating range. Differences are in packaging format and RoHS compliance: IRLR014PBF is supplied in Tube; IRLR014TR has unspecified packaging; IRLR014TRL has unspecified packaging; IRLR014TRLPBF is supplied in Tape & Reel with ROHS3 compliance; IRLR014TRPBF is supplied in Cut Tape & Digi-Reel® with ROHS3 compliance; IRLR014TRR has unspecified packaging. Selection depends on packaging requirements and regulatory compliance needs for the end application.

Q3: Is BUK72150-55A,118 a better choice than IRLR014TRLPBF?

BUK72150-55A,118 maintains the original 55V voltage class and provides 11A continuous current, exceeding the original 10A specification. It carries AEC-Q101 automotive qualification and ROHS3 compliance. Operating temperature range is -55°C to 175°C, matching the original part. Power dissipation is 36W, exceeding the original 28W. This part is superior for applications requiring strict voltage class adherence, automotive-grade reliability, and full operating temperature range. IRLR014TRLPBF is suitable for applications where 60V voltage derating is acceptable and current demand does not exceed 7.7A.

Q4: Can STD12NF06T4 replace IRLR014NTR in high-current applications?

STD12NF06T4 provides 60V Vdss with 12A continuous current, exceeding the original 10A specification by 20%. On-resistance is 100 mOhm @ 6A, 10V, providing superior thermal performance compared to the original 140 mOhm. Operating temperature range is -55°C to 175°C, matching the original part. Power dissipation is 30W, exceeding the original 28W. This part is suitable for applications requiring higher current capacity and improved thermal performance within the 60V voltage class. ROHS3 compliance is confirmed.

Q5: What are the package compatibility considerations?

All substitute parts listed are supplied in TO-252-3 DPAK (2 Leads + Tab) package, identical to the original IRLR014NTR. This ensures mechanical and thermal compatibility with existing PCB layouts and thermal management designs. Differences exist only in packaging format (Tube, Cut Tape, Tape & Reel, Digi-Reel®), which affects supply chain logistics but not electrical or mechanical performance. Selection of packaging format depends on production volume and inventory management requirements.

Q6: Are there compliance or regulatory differences between substitute parts?

IRLR014NTR is RoHS non-compliant and obsolete. BUK72150-55A,118 is ROHS3 compliant and AEC-Q101 automotive qualified. IRLR014TRLPBF and IRLR014TRPBF are ROHS3 compliant and active production parts. IRLR014PBF, IRLR014TR, IRLR014TRL, and IRLR014TRR have varying RoHS compliance status. STD12NF06T4 and STD6NF10T4 are ROHS3 compliant. For applications requiring RoHS compliance, select parts explicitly marked ROHS3 compliant. For automotive applications, BUK72150-55A,118 is the only substitute with AEC-Q101 qualification.

Q7: What is the impact of on-resistance differences on circuit performance?

IRLR014NTR has 140 mOhm on-resistance @ 6A, 10V. IRLR014 variants have 200 mOhm, resulting in 43% higher on-resistance and increased power dissipation. STD12NF06T4 has 100 mOhm, resulting in 29% lower on-resistance and reduced power dissipation. STD6NF10T4 has 250 mOhm, resulting in 79% higher on-resistance. Lower on-resistance reduces heat generation and improves efficiency. Higher on-resistance increases heat generation and may require enhanced thermal management. Circuit thermal analysis is required when substituting parts with significantly different on-resistance values.

Q8: Can STD6NF10T4 be used as a substitute?

STD6NF10T4 is rated at 100V Vdss with 6A continuous current. This part is not recommended as a direct substitute for the IRLR014NTR in standard 55V applications because the 100V rating is excessive for 55V circuits and the 6A current rating is below the original 10A specification. This part is suitable only for circuits where higher voltage margin is required and current demand does not exceed 6A. On-resistance is 250 mOhm @ 3A, 10V, which is significantly higher than the original part, resulting in increased power dissipation and reduced efficiency.
