Substitute Part Grouping Explanation

Substitution of the IRLU014 is determined by strict equivalence across the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

• FET Type: N-Channel topology
• Technology: MOSFET (Metal Oxide) construction
• Drain to Source Voltage (Vdss): 60V rating
• Continuous Drain Current (Id): 7.7A at 25°C
• On-State Resistance (Rds On): 200mOhm maximum at specified conditions
• Gate Threshold Voltage (Vgs(th)): 2V at 250µA
• Gate Charge (Qg): 8.4nC at 5V
• Input Capacitance (Ciss): 400pF at 25V
• Power Dissipation: 2.5W (Ta), 25W (Tc)
• Operating Temperature Range: -55°C to 150°C

Mechanical Equivalence Criteria:

• Mounting Type: Through Hole
• Package / Case: TO-251-3 Short Leads, IPak, TO-251AA
• Supplier Device Package: TO-251AA

Substitute parts must maintain identical electrical performance across all specified parameters and be compatible with the same PCB footprint and thermal management design. Packaging format (Tube versus other configurations) does not affect electrical or mechanical compatibility.

Engineering Selection Recommendations

IRLU014PBF Selection Basis:

The IRLU014PBF is a direct parametric equivalent to the IRLU014, sharing identical electrical specifications and mechanical package configuration. Both devices are manufactured by Vishay Siliconix and maintain Active product status, ensuring long-term availability and design continuity.

The primary distinction between these parts is regulatory compliance status. The IRLU014 is RoHS non-compliant, while the IRLU014PBF is ROHS3 Compliant. This difference is significant for applications subject to RoHS (Restriction of Hazardous Substances) regulations, particularly in European markets and industries with mandatory environmental compliance requirements.

From an electrical and mechanical standpoint, the IRLU014PBF provides complete interchangeability with the IRLU014. Both devices support identical circuit designs, PCB layouts, and thermal management strategies. The packaging format difference (Tube for IRLU014PBF versus unspecified for IRLU014) does not affect component performance or compatibility.

Selection between these parts should be based on:

• Regulatory compliance requirements of the end application
• Supply chain availability and lead time considerations
• Procurement specifications mandating RoHS compliance status

Frequently Asked Questions (FAQ)

Q: Can IRLU014PBF be used as a direct replacement for IRLU014 in existing designs?

A: Yes. The IRLU014PBF is electrically and mechanically identical to the IRLU014. All electrical parameters, including Vdss, Id, Rds On, gate charge, and capacitance specifications, are identical. Both devices use the same TO-251AA package with identical pin configuration and footprint. No circuit modifications or PCB redesign is required.

Q: What is the difference between IRLU014 and IRLU014PBF?

A: The primary difference is RoHS compliance status. IRLU014PBF is ROHS3 Compliant, while IRLU014 is RoHS non-compliant. Electrical performance and mechanical packaging are identical. The IRLU014PBF is supplied in Tube packaging format.

Q: Are there any thermal management differences between IRLU014 and IRLU014PBF?

A: No. Both devices have identical power dissipation ratings of 2.5W (Ta) and 25W (Tc), identical operating temperature ranges of -55°C to 150°C, and identical thermal characteristics. Thermal design considerations remain unchanged when substituting between these parts.

Q: What is the significance of the TO-251AA package for these devices?

A: The TO-251AA package is a Through Hole configuration with three leads in a short-lead format, also known as IPak. This package provides direct PCB mounting compatibility and is suitable for applications requiring Through Hole assembly. Both IRLU014 and IRLU014PBF use this identical package, ensuring mechanical interchangeability.

Q: Can IRLU014PBF handle the same current and voltage ratings as IRLU014?

A: Yes. Both devices are rated for 60V drain-to-source voltage and 7.7A continuous drain current at 25°C. On-state resistance is 200mOhm maximum at 4.6A and 5V gate-source voltage for both parts. All electrical performance specifications are identical.

Q: Is RoHS compliance important for my application?

A: RoHS compliance is mandatory for products sold in the European Union and is increasingly required by major manufacturers and procurement standards globally. If your application or end market requires RoHS compliance, IRLU014PBF is the appropriate selection. If RoHS compliance is not a requirement, either part is suitable.

Q: What inventory levels are available for these parts?

A: IRLU014 has 2214 pieces in stock. IRLU014PBF has 15465 pieces in stock. Availability may vary based on current procurement and supply chain conditions.
