Engineering Selection Recommendations

IRLL110TRPBF (Direct Equivalent - Recommended Primary Substitute)

The IRLL110TRPBF is the direct equivalent of the obsolete IRLL110PBF. Both parts are manufactured by Vishay Siliconix and share identical electrical specifications across all critical parameters: 100V Vdss, 1.5A continuous drain current, 540 mOhm Rds On, and 2W/3.1W power dissipation. The IRLL110TRPBF is currently in active production status with 30,320 units in stock, providing immediate procurement availability. This part maintains the same SOT-223 package pinout and is ROHS3 compliant with MSL 1 rating. The IRLL110TRPBF is supplied in Cut Tape and Digi-Reel packaging formats.

ZVN4310GTA (Manufacturer-Recommended Alternative)

The ZVN4310GTA, manufactured by Diodes Incorporated, is a manufacturer-recommended alternative with equivalent 100V Vdss rating and higher continuous drain current of 1.67A. This part meets or exceeds the electrical requirements of the IRLL110PBF with 540 mOhm Rds On specification and 3W power dissipation capability. The ZVN4310GTA operates across the same temperature range (-55°C to 150°C) and is ROHS3 compliant. The part is supplied in SOT-223-3 package format with 25,720 units in stock. Gate threshold voltage is 3V at 1mA, which is compatible with standard 5V drive circuits.

ZXMN10A11GTA (Manufacturer-Recommended Alternative)

The ZXMN10A11GTA, manufactured by Diodes Incorporated, is a manufacturer-recommended alternative with equivalent 100V Vdss rating and 1.7A continuous drain current. This part features superior on-state resistance of 350 mOhm at 2.6A and 10V, providing lower conduction losses compared to the IRLL110PBF. Power dissipation is rated at 2W, matching the ambient temperature rating of the original part. The ZXMN10A11GTA operates across the same temperature range and is ROHS3 compliant. The part is supplied in SOT-223-3 package format with 24,200 units in stock. Gate charge is 5.4 nC at 10V, indicating efficient switching characteristics.

All three substitute parts are ROHS3 compliant, carry MSL 1 ratings, and maintain the same ECCN (EAR99) and HTSUS (8541.29.0095) classifications as the original IRLL110PBF.

Frequently Asked Questions (FAQ)

Q: Can the IRLL110TRPBF be used as a direct replacement for the IRLL110PBF?

A: Yes. The IRLL110TRPBF is the direct equivalent manufactured by Vishay Siliconix with identical electrical specifications and SOT-223 package pinout. The only difference is product status: IRLL110TRPBF is active production while IRLL110PBF is obsolete. No circuit modifications are required.

Q: What is the difference between the IRLL110TRPBF and the Diodes Incorporated alternatives?

A: The IRLL110TRPBF is a direct manufacturer equivalent from Vishay Siliconix with identical specifications. The ZVN4310GTA and ZXMN10A11GTA are alternatives from a different manufacturer (Diodes Incorporated) with equivalent or superior electrical performance. All three parts share the same 100V Vdss rating, SOT-223 package, and operating temperature range, but differ in continuous drain current, on-state resistance, and gate threshold voltage specifications.

Q: Are the SOT-223 and SOT-223-3 packages pin-compatible?

A: Both SOT-223 and SOT-223-3 designations refer to the same physical package format (TO-261-4, TO-261AA) with identical pinout. The "-3" designation in SOT-223-3 indicates a three-terminal configuration, which is standard for all MOSFETs in this package family. Pin compatibility is maintained across all substitute parts.

Q: Which substitute part should be selected for lowest on-state resistance?

A: The ZXMN10A11GTA provides the lowest on-state resistance at 350 mOhm (measured at 2.6A and 10V gate voltage), compared to 540 mOhm for both the IRLL110PBF and IRLL110TRPBF. Lower on-state resistance reduces conduction losses and heat dissipation in switching applications.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The IRLL110TRPBF, ZVN4310GTA, and ZXMN10A11GTA are all ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity ratings. All parts carry the same ECCN (EAR99) and HTSUS (8541.29.0095) classifications.

Q: What is the gate threshold voltage difference between the alternatives?

A: The IRLL110PBF and IRLL110TRPBF have Vgs(th) of 2V at 250µA. The ZVN4310GTA has Vgs(th) of 3V at 1mA, and the ZXMN10A11GTA has Vgs(th) of 4V at 250µA. Higher gate threshold voltages require higher drive voltages for full on-state conduction. Circuits designed for 5V gate drive are compatible with all alternatives, though switching speed may vary.

Q: Can the higher current-rated alternatives (1.67A and 1.7A) be used in applications requiring only 1.5A?

A: Yes. The ZVN4310GTA (1.67A) and ZXMN10A11GTA (1.7A) have higher continuous drain current ratings than the IRLL110PBF (1.5A). Using a higher-rated device in a lower-current application does not create compatibility issues. The device will operate within its safe operating area with reduced thermal stress.

Q: What is the inventory status of each substitute part?

A: IRLL110TRPBF has 30,320 units in stock, ZVN4310GTA has 25,720 units in stock, and ZXMN10A11GTA has 24,200 units in stock. All parts are available for immediate procurement.
