Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the IRFR110TRLPBF are identified based on the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

• Drain-to-Source Voltage (Vdss): Must equal or exceed 100V
• FET Type: Must be N-Channel MOSFET
• Package Type: Must be DPAK (TO-252-3) Surface Mount
• Gate Threshold Voltage (Vgs(th)): Must be compatible at specified test conditions
• Maximum Gate Voltage (Vgs Max): Must accommodate ±20V operation

Secondary Compatibility Parameters:

• Continuous Drain Current (Id): Equal or greater current rating acceptable
• RDS(on): Lower or equal on-resistance acceptable
• Operating Temperature Range: Must support -55°C to 150°C minimum
• Mounting Type: Surface Mount required for PCB compatibility

Parts meeting these criteria can be directly substituted without circuit redesign, provided the application does not require exact parameter matching for current limiting or thermal management purposes.

Engineering Selection Recommendations

IRFR110TRLPBF-BE3 (Vishay Siliconix)

This part is a direct equivalent from the same manufacturer with identical electrical specifications. Both parts maintain Active product status and ROHS3 compliance. The IRFR110TRLPBF-BE3 is suitable for applications requiring long-term supply continuity and manufacturer support. Packaging designation differs slightly (TO-252AA versus DPAK), but both conform to the same physical footprint (TO-252-3). This substitute is recommended for new designs and production continuity.

BUK7275-100A,118 (Nexperia USA Inc.)

This part exceeds the electrical specifications of the IRFR110TRLPBF with higher continuous drain current (21.7A versus 4.3A), lower on-resistance (75mOhm versus 540mOhm), and greater power dissipation capability (89W versus 25W). The BUK7275-100A,118 is qualified to AEC-Q101 automotive standards and supports extended operating temperature to 175°C. However, this part carries Obsolete product status, indicating discontinued manufacturing. The significantly higher input capacitance (1210pF versus 180pF) may affect gate drive circuit performance. This substitute is suitable only for applications where higher current capacity and thermal performance are required and where obsolete part availability is acceptable.

Frequently Asked Questions (FAQ)

Q: Can IRFR110TRLPBF-BE3 be used as a direct replacement for IRFR110TRLPBF?

A: Yes. Both parts are manufactured by Vishay Siliconix with identical electrical specifications, including Vdss (100V), Id (4.3A), RDS(on) (540mOhm), and operating temperature range (-55°C to 150°C). Both are packaged in DPAK (TO-252-3) Surface Mount configuration. The parts are electrically and mechanically interchangeable.

Q: What are the key differences between IRFR110TRLPBF and BUK7275-100A,118?

A: The BUK7275-100A,118 is rated for significantly higher continuous drain current (21.7A versus 4.3A) and lower on-resistance (75mOhm versus 540mOhm), resulting in higher power dissipation capability (89W versus 25W). The BUK7275 also features extended operating temperature to 175°C and AEC-Q101 automotive qualification. However, the BUK7275 has higher input capacitance (1210pF versus 180pF) and is classified as Obsolete. Both maintain 100V Vdss rating and DPAK packaging.

Q: Is the BUK7275-100A,118 suitable for applications designed for IRFR110TRLPBF?

A: The BUK7275-100A,118 can be used in applications where the IRFR110TRLPBF is specified, provided the circuit design accommodates the higher input capacitance and gate charge characteristics. The superior current and thermal ratings of the BUK7275 make it suitable for higher-power applications. However, the Obsolete product status limits long-term availability.

Q: Are there packaging compatibility concerns between these substitutes?

A: All three parts use DPAK (TO-252-3) Surface Mount packaging with identical pinout and footprint. PCB layout and component placement are directly compatible without modification.

Q: What compliance certifications apply to each part?

A: IRFR110TRLPBF and BUK7275-100A,118 are both ROHS3 Compliant. IRFR110TRLPBF-BE3 is REACH Affected. The BUK7275-100A,118 carries AEC-Q101 automotive qualification. All parts are classified as EAR99 for export control purposes.

Q: How does the higher input capacitance of BUK7275-100A,118 affect circuit performance?

A: Input capacitance (Ciss) of 1210pF in the BUK7275 versus 180pF in the IRFR110 requires higher gate drive current and longer switching times. Gate drive circuits must be evaluated for compatibility with the increased capacitive load. Applications with high-frequency switching may experience reduced efficiency.

Q: What is the significance of Obsolete product status for BUK7275-100A,118?

A: Obsolete status indicates the manufacturer has discontinued production. While current inventory may be available, future supply cannot be guaranteed. New designs should not specify obsolete parts unless alternative solutions are unavailable.
