IRLR014NPBF N-Channel 55V 10A MOSFET DPAK Equivalent & Substitute Parts

Part Overview

The IRLR014NPBF is an N-Channel MOSFET manufactured by Infineon Technologies, rated for 55V drain-to-source voltage and 10A continuous drain current in a surface mount DPAK package. This device is classified as obsolete, necessitating identification of equivalent and substitute components for ongoing design support and procurement.

The IRLR014NPBF operates across a temperature range of -55°C to 175°C and dissipates up to 28W at the case temperature. Its HEXFET® series designation indicates advanced gate oxide technology. Due to its obsolete status, equivalent parts from active product lines and alternative manufacturers provide continuity for applications requiring similar electrical and mechanical characteristics.

Substitute Part Grouping Explanation

Substitution of the IRLR014NPBF is determined by the following critical parameters:

Voltage Rating Compatibility: The drain-to-source voltage (Vdss) must equal or exceed 55V. Substitute parts with higher voltage ratings (60V, 100V) are acceptable for applications operating within the original 55V specification.

Current Capability: The continuous drain current (Id) at 25°C must support the application's maximum current demand. The IRLR014NPBF specifies 10A; substitutes with equal or greater current ratings are functionally compatible.

On-State Resistance (Rds On): This parameter directly affects power dissipation and thermal performance. Substitutes with comparable or lower Rds On values maintain or improve efficiency characteristics.

Package and Pinout: All substitute parts must use the TO-252-3 DPAK package with identical pin configuration to ensure mechanical and electrical compatibility without PCB redesign.

Operating Temperature Range: The substitute must support the application's thermal environment. The IRLR014NPBF operates from -55°C to 175°C; substitutes with equal or wider temperature ranges are acceptable.

Gate Charge and Input Capacitance: These parameters affect switching speed and gate drive requirements. Substitutes with similar or lower values maintain compatible drive circuit performance.

Engineering Selection Recommendations

Primary Substitute: IRLR014TRPBF (Vishay Siliconix)

The IRLR014TRPBF is the preferred substitute for the IRLR014NPBF. Both devices share the same base product number (IRLR014) and are manufactured by Vishay Siliconix. The IRLR014TRPBF maintains identical electrical specifications: 60V Vdss, 7.7A continuous drain current, 200mOhm Rds On, and TO-252-3 DPAK packaging. The device is in active production status with ROHS3 compliance, ensuring long-term availability and regulatory conformance. The higher voltage rating (60V vs. 55V) provides additional design margin without affecting applications designed for 55V operation. Inventory availability is substantial at 17,695 pieces.

Secondary Substitute: IRLR014PBF (Vishay Siliconix)

The IRLR014PBF offers equivalent electrical performance to the IRLR014TRPBF with identical specifications and active product status. This variant is supplied in tube packaging rather than tape and reel, suitable for lower-volume procurement. ROHS3 compliance is confirmed. Inventory is available at 2,100 pieces.

Alternative Substitute: BUK72150-55A,118 (Nexperia USA Inc.)

The BUK72150-55A,118 provides exact voltage matching at 55V Vdss with superior current capability at 11A continuous drain current. This TrenchMOS™ device delivers 36W power dissipation and maintains the same -55°C to 175°C operating range. The device carries AEC-Q101 automotive qualification and ROHS3 compliance. On-state resistance is 150mOhm at 5A, 10V, slightly higher than the main part but within acceptable tolerance for most applications. Inventory is available at 20,536 pieces. This substitute is suitable for applications requiring exact voltage matching and automotive-grade reliability.

Higher Voltage Alternative: STD6NF10T4 (STMicroelectronics)

The STD6NF10T4 operates at 100V Vdss with 6A continuous drain current in the STripFET™ series. This device is suitable only for applications where the higher voltage rating does not create design conflicts. The 250mOhm Rds On is higher than the main part, resulting in increased power dissipation. Operating temperature range extends to -65°C, providing wider low-temperature capability. ROHS3 compliance and active product status are confirmed. This substitute is appropriate for designs requiring higher voltage headroom or extended low-temperature operation. Inventory is available at 22,375 pieces.

Variant Substitutes: IRLR014TRL, IRLR014TRLPBF, IRLR014TRR (Vishay Siliconix)

These variants share identical electrical specifications with IRLR014TRPBF but differ in packaging configuration and RoHS compliance status. IRLR014TRLPBF is ROHS3 compliant with tape and reel packaging (3,400 pieces available). IRLR014TRL and IRLR014TRR are RoHS non-compliant variants with lower inventory levels (2,200 and 873 pieces respectively). These variants are functionally equivalent but should be selected only when specific packaging or compliance requirements align with application needs.

Frequently Asked Questions (FAQ)

Q: Can IRLR014TRPBF directly replace IRLR014NPBF without PCB modification?

A: Yes. Both devices use identical TO-252-3 DPAK packaging with the same pin configuration (Gate, Drain, Source). No PCB layout changes are required. The higher 60V rating of IRLR014TRPBF is backward compatible with 55V applications.

Q: What is the difference between IRLR014TRPBF and IRLR014PBF?

A: Both devices have identical electrical specifications and active product status. The primary difference is packaging: IRLR014TRPBF is supplied in cut tape and Digi-Reel format, while IRLR014PBF is supplied in tube packaging. Selection depends on procurement volume and assembly line requirements.

Q: Why does BUK72150-55A,118 have higher current rating (11A) than IRLR014NPBF (10A)?

A: The BUK72150-55A,118 uses Nexperia's TrenchMOS™ technology, which provides improved current handling capability at the same voltage rating. The higher current rating does not affect compatibility; applications requiring 10A operation will function correctly with this substitute.

Q: Is STD6NF10T4 suitable as a direct replacement?

A: STD6NF10T4 is functionally compatible only if the application circuit can tolerate 100V Vdss and 6A maximum current. The higher voltage rating and lower current capability make this substitute appropriate only for specific design scenarios. The 250mOhm Rds On results in higher power dissipation than the main part.

Q: What is the significance of RoHS compliance status in substitute selection?

A: ROHS3-compliant devices (IRLR014TRPBF, IRLR014PBF, BUK72150-55A,118, STD6NF10T4) meet European Union Restriction of Hazardous Substances regulations and are suitable for applications subject to environmental compliance requirements. RoHS non-compliant variants (IRLR014TRL, IRLR014TRR) should be selected only when compliance is not a requirement.

Q: How do gate charge differences affect circuit design?

A: Gate charge (Qg) determines the energy required to switch the MOSFET. IRLR014NPBF specifies 7.9nC at 5V, while substitutes range from 5.5nC to 14nC. Lower gate charge reduces gate drive power and switching losses. Existing gate drive circuits designed for the main part will function with substitutes having similar or lower gate charge values.

Q: Can multiple substitute parts be used interchangeably in the same design?

A: Yes, provided the application circuit accommodates the parameter variations listed in the comparison table. For high-volume production, selecting a single substitute ensures consistent performance and simplifies supply chain management. IRLR014TRPBF is recommended as the standard substitute due to active product status, availability, and electrical compatibility.

Q: What inventory considerations apply to substitute selection?

A: STD6NF10T4 has the highest inventory (22,375 pieces), followed by BUK72150-55A,118 (20,536 pieces) and IRLR014TRPBF (17,695 pieces). For long-term production programs, IRLR014TRPBF is preferred due to active product status and ROHS3 compliance, despite slightly lower inventory levels.
