IRLR110TR N-Channel MOSFET 100V 4.3A DPAK Equivalent & Substitute Parts

Part Overview

The IRLR110TR is an N-Channel MOSFET manufactured by Vishay Siliconix, rated for 100V drain-to-source voltage with 4.3A continuous drain current in a surface mount DPAK package. This device is classified as Active product status and is RoHS non-compliant. Equivalent and substitute parts are identified based on matching or exceeding electrical performance parameters while maintaining compatible package form factors and operating characteristics. Substitutes are necessary when the primary part experiences supply constraints, obsolescence, or when design requirements permit higher performance specifications within the same package class.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the IRLR110TR is based on the following criteria:

Primary Equivalence (Parametric Match): Parts must maintain identical or superior electrical specifications across all critical parameters: Vdss (100V minimum), continuous drain current (4.3A minimum), Rds On characteristics, gate threshold voltage, and operating temperature range. Package compatibility requires DPAK (TO-252-3) form factor with surface mount capability.

Secondary Equivalence (Performance Upgrade): Parts exceeding the IRLR110TR specifications in drain current, power dissipation, or gate charge while maintaining 100V Vdss rating and DPAK packaging are classified as functional substitutes. These parts support the same circuit topology with enhanced current handling or thermal performance.

Compliance Consideration: RoHS status and product lifecycle status (Active vs. Obsolete) are documented but do not restrict substitution eligibility. Moisture sensitivity level (MSL 1 - Unlimited) is consistent across all listed parts.

Key Substitution Parameters:

• Drain to Source Voltage (Vdss): 100V
• Package Type: DPAK (TO-252-3)
• Mounting Type: Surface Mount
• FET Technology: N-Channel MOSFET
• Continuous Drain Current: ≥4.3A
• Operating Temperature: -55°C minimum to 150°C maximum

Parameter Comparison

Engineering Selection Recommendations

IRLR110TRPBF (Vishay Siliconix): This part is a parametric equivalent to the IRLR110TR with identical electrical specifications. The primary distinction is packaging format (Cut Tape & Digi-Reel versus standard packaging) and RoHS3 compliance status. IRLR110TRPBF is recommended as the direct replacement when RoHS3 compliance is required or when supply of the base IRLR110TR is constrained. Product status is Active with higher inventory availability (15,165 pcs vs. 1,153 pcs).

STD6NF10T4 (STMicroelectronics): This part provides a performance upgrade within the same DPAK package. Continuous drain current is increased to 6A (versus 4.3A), and power dissipation capability is enhanced to 30W (Tc). Rds On is reduced to 250 mOhm at 3A, 10V, providing lower on-state losses. Operating temperature range extends to 175°C. STD6NF10T4 is suitable for applications requiring higher current handling or improved thermal performance while maintaining 100V Vdss rating. Product status is Active with substantial inventory (22,375 pcs).

BUK7275-100A,118 (Nexperia USA Inc.): This part represents a significant performance upgrade with 21.7A continuous drain current and 89W power dissipation capability. Rds On is substantially lower at 75 mOhm. However, product status is Obsolete, indicating discontinued manufacturing. BUK7275-100A,118 is not recommended for new designs. This part is listed for reference only in applications where existing inventory or legacy system compatibility is required.

Compliance and Lifecycle Considerations: IRLR110TRPBF and STD6NF10T4 are both ROHS3 compliant and Active products, making them suitable for current procurement and new design implementation. The IRLR110TR base part is RoHS non-compliant; migration to IRLR110TRPBF is recommended for regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can IRLR110TRPBF be used as a direct replacement for IRLR110TR?

A: Yes. IRLR110TRPBF is a parametric equivalent with identical electrical specifications: 100V Vdss, 4.3A continuous drain current, 540 mOhm Rds On, and identical gate charge and input capacitance values. Both use DPAK (TO-252-3) packaging. The primary difference is RoHS3 compliance status and packaging format (Cut Tape & Digi-Reel). Pin configuration and electrical performance are identical.

Q: What are the advantages of using STD6NF10T4 instead of IRLR110TR?

A: STD6NF10T4 provides higher continuous drain current (6A versus 4.3A), lower on-state resistance (250 mOhm versus 540 mOhm), and greater power dissipation capability (30W versus 25W at Tc). Operating temperature range extends to 175°C. These improvements reduce thermal stress and enable operation in higher current applications. DPAK packaging remains identical, ensuring mechanical compatibility.

Q: Is BUK7275-100A,118 suitable for new designs?

A: No. BUK7275-100A,118 is classified as Obsolete product status, indicating discontinued manufacturing. While parametric data is provided for reference, this part should not be selected for new designs. Use STD6NF10T4 or IRLR110TRPBF for current applications.

Q: Are all substitute parts available in the same DPAK package?

A: Yes. All listed parts (IRLR110TRPBF, BUK7275-100A,118, and STD6NF10T4) use DPAK (TO-252-3) surface mount packaging with identical pin configuration. Physical board layout compatibility is maintained across all substitutes.

Q: What is the difference between IRLR110TR and IRLR110TRPBF packaging?

A: IRLR110TR uses standard packaging, while IRLR110TRPBF is supplied in Cut Tape (CT) and Digi-Reel format. Electrical specifications are identical. Packaging format selection depends on assembly process requirements and inventory management preferences.

Q: Can STD6NF10T4 be used in applications designed for IRLR110TR?

A: Yes, with design verification. STD6NF10T4 exceeds IRLR110TR specifications in all critical parameters: higher drain current (6A vs. 4.3A), lower Rds On (250 mOhm vs. 540 mOhm), and higher power dissipation (30W vs. 25W). Gate threshold voltage is higher (4V vs. 2V), which may affect gate drive circuit timing. Input capacitance is slightly higher (280 pF vs. 250 pF). These differences require circuit-level verification to confirm compatibility with existing gate drive and thermal management designs.

Q: What is the moisture sensitivity level for these parts?

A: All listed parts have Moisture Sensitivity Level (MSL) 1, classified as Unlimited. This indicates no moisture sensitivity restrictions during storage, handling, or assembly processes.

Q: Are all substitute parts RoHS compliant?

A: IRLR110TRPBF and STD6NF10T4 are ROHS3 compliant. IRLR110TR is RoHS non-compliant. BUK7275-100A,118 is ROHS3 compliant but Obsolete. For new designs requiring RoHS compliance, select IRLR110TRPBF or STD6NF10T4.
