IRLD110 Equivalent & Substitute Parts

Part Overview

The IRLD110 is an N-Channel MOSFET rated for 100V drain-to-source voltage with 1A continuous drain current at 25°C. This device is packaged in a 4-HVMDIP through-hole configuration and is designed for general-purpose switching applications requiring moderate voltage and current ratings.

The IRLD110 carries an Obsolete product status, making it necessary to identify equivalent and substitute components for new designs and ongoing production requirements. The primary substitute maintains identical electrical specifications while offering improved availability and compliance status.

Substitute Part Grouping Explanation

Substitution of the IRLD110 is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must satisfy the following criteria:

Electrical Equivalence Requirements:

• Identical FET type (N-Channel)
• Matching Drain to Source Voltage (Vdss): 100V
• Matching Continuous Drain Current (Id): 1A @ 25°C
• Matching Rds On specifications: 540mOhm @ 600mA, 5V
• Matching Gate Threshold Voltage (Vgs(th)): 2V @ 250µA
• Matching Gate Charge (Qg): 6.1nC @ 5V
• Matching Input Capacitance (Ciss): 250pF @ 25V
• Matching Power Dissipation: 1.3W
• Matching Operating Temperature Range: -55°C to 175°C

Mechanical Equivalence Requirements:

• Identical mounting type: Through Hole
• Identical package: 4-DIP (0.300", 7.62mm)
• Identical supplier device package: 4-HVMDIP

The IRLD110PBF is a direct substitute that maintains complete electrical and mechanical compatibility while offering improved product status and compliance certifications.

Engineering Selection Recommendations

The IRLD110PBF is the direct equivalent substitute for the obsolete IRLD110. Selection of IRLD110PBF is based on the following factors:

Product Status: The IRLD110 is classified as Obsolete, while IRLD110PBF maintains Active product status. This ensures long-term availability and continued manufacturer support for new production and design implementations.

Compliance Certification: IRLD110PBF is ROHS3 Compliant, whereas the original IRLD110 is RoHS non-compliant. This compliance improvement aligns with current regulatory requirements for electronic components in regulated markets.

Electrical and Mechanical Equivalence: All electrical parameters and mechanical specifications are identical between the two parts. Direct pin-for-pin and functional substitution is supported without circuit modification.

Packaging and Inventory: IRLD110PBF is supplied in Tube packaging with significantly higher inventory availability (17,000 Pcs) compared to the original part (4,460 Pcs), supporting both prototype and production-volume requirements.

For new designs and production transitions, IRLD110PBF is the appropriate selection. For legacy systems currently using IRLD110, direct replacement with IRLD110PBF is supported without design changes.

Frequently Asked Questions (FAQ)

Q: Can IRLD110PBF be used as a direct replacement for IRLD110 in existing circuits?

A: Yes. IRLD110PBF is electrically and mechanically identical to IRLD110. All electrical parameters, including Vdss, Id, Rds On, Vgs(th), gate charge, and input capacitance, are matched. The 4-DIP through-hole package is identical, supporting direct PCB substitution without circuit modification.

Q: What is the primary reason to transition from IRLD110 to IRLD110PBF?

A: The IRLD110 is classified as Obsolete, creating supply chain risk for ongoing production. IRLD110PBF maintains Active product status with higher inventory availability and ROHS3 compliance, ensuring long-term component availability and regulatory alignment.

Q: Are there any differences in thermal or electrical performance between IRLD110 and IRLD110PBF?

A: No. Both parts share identical thermal specifications (1.3W maximum power dissipation) and electrical characteristics across all rated parameters. Operating temperature range, gate charge, and on-resistance specifications are equivalent.

Q: What packaging formats are available for IRLD110PBF?

A: IRLD110PBF is supplied in Tube packaging. Both the original IRLD110 and substitute IRLD110PBF use the 4-HVMDIP supplier device package, which corresponds to the 4-DIP (0.300", 7.62mm) case format for through-hole mounting.

Q: Is IRLD110PBF suitable for new product designs?

A: Yes. IRLD110PBF is the recommended component for new designs. Its Active product status, ROHS3 compliance, and high inventory availability make it the appropriate choice for both prototype development and production implementation.

Q: Are there any moisture sensitivity or handling differences between the two parts?

A: No. Both IRLD110 and IRLD110PBF carry Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating no special moisture control requirements during storage or handling.
