IRFL9110 P-Channel MOSFET Equivalent & Substitute Parts

Part Overview

The IRFL9110 is a P-Channel Metal Oxide Semiconductor Field Effect Transistor (MOSFET) rated for 100V drain-to-source voltage with a continuous drain current of 1.1A at 25°C. The device is packaged in a surface mount SOT-223 configuration and is designed for applications requiring moderate power dissipation in compact form factors.

The IRFL9110 carries an Obsolete product status, indicating that the original part number is no longer in active production. This necessitates identification of functionally equivalent alternatives that maintain identical electrical and mechanical specifications while offering active availability and current manufacturing compliance.

Substitute Part Grouping Explanation

Substitution of the IRFL9110 is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must maintain identical specifications for drain-to-source voltage rating, continuous drain current capacity, on-state resistance characteristics, gate threshold voltage, and thermal performance. Additionally, the substitute must be compatible with the SOT-223 surface mount package footprint and land pattern.

The IRFL9110TRPBF qualifies as a direct substitute based on the following criteria:

  • Identical FET type classification (P-Channel MOSFET)
  • Matching Vdss rating (100V)
  • Equivalent continuous drain current (1.1A @ 25°C)
  • Identical Rds On specification (1.2Ω @ 660mA, 10V)
  • Matching gate threshold voltage (4V @ 250µA)
  • Identical gate charge (8.7nC @ 10V)
  • Matching input capacitance (200pF @ 25V)
  • Identical power dissipation rating (2W Ta, 3.1W Tc)
  • Matching operating temperature range (-55°C to 150°C)
  • Identical package configuration (SOT-223)
  • Same moisture sensitivity level (MSL 1)
