Key Parameters

Substitute Part Grouping Explanation

Substitution of the IXFK110N07 is determined by the following critical electrical and mechanical parameters:

Voltage Rating Compatibility: The substitute part must support applications where the IXFK110N07 operates. The IXFK240N15T2 features a higher Vdss rating of 150V, which is suitable for circuits designed for the 70V IXFK110N07 since higher voltage-rated devices can operate safely in lower voltage applications.

Current Handling Capacity: The IXFK240N15T2 provides 240A continuous drain current, exceeding the 110A specification of the IXFK110N07. This higher current capability allows the substitute to handle equivalent or increased load requirements.

On-State Resistance: The IXFK240N15T2 exhibits 5.2 mOhm Rds On (Max) compared to 6 mOhm for the IXFK110N07, representing improved efficiency characteristics.

Package Compatibility: Both devices use identical TO-264AA (IXFK) through-hole packaging, ensuring mechanical and thermal interface compatibility.

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

The IXFK240N15T2 serves as a direct substitute for the IXFK110N07 based on the following engineering criteria:

Product Status Alignment: The IXFK110N07 carries a Not For New Designs status, while the IXFK240N15T2 is Active. For new circuit designs and ongoing production requiring component replacement, the IXFK240N15T2 is the appropriate selection.

Regulatory Compliance: Both devices maintain identical RoHS3 compliance and REACH unaffected status, ensuring no regulatory barriers to substitution.

Electrical Performance Enhancement: The IXFK240N15T2 provides superior electrical characteristics including higher voltage rating (150V vs. 70V), increased current capacity (240A vs. 110A), and improved on-state resistance (5.2 mOhm vs. 6 mOhm). These enhancements support applications with equivalent or increased performance requirements.

Thermal Capability: The IXFK240N15T2 offers extended operating temperature range (-55°C to 175°C versus -55°C to 150°C) and higher power dissipation rating (1250W versus 500W), providing greater thermal margin in demanding applications.

Package Compatibility: Identical TO-264AA through-hole packaging ensures direct mechanical and thermal interface compatibility without PCB redesign.

Frequently Asked Questions (FAQ)

Q: Can the IXFK240N15T2 directly replace the IXFK110N07 in existing circuits?

A: Yes. Both devices share identical TO-264AA through-hole packaging and compatible electrical drive characteristics (±20V Vgs Max, 10V drive voltage). The IXFK240N15T2 higher voltage and current ratings ensure safe operation in circuits designed for the IXFK110N07.

Q: What are the key differences between these two MOSFETs?

A: The IXFK240N15T2 provides higher Vdss (150V vs. 70V), higher continuous drain current (240A vs. 110A), lower on-state resistance (5.2 mOhm vs. 6 mOhm), higher power dissipation capability (1250W vs. 500W), and extended operating temperature range (175°C vs. 150°C). Input capacitance is higher at 32000 pF versus 9000 pF.

Q: Are there any compatibility concerns with gate drive circuits?

A: No. Both devices operate with identical maximum gate voltage (±20V) and similar gate threshold voltage specifications (4V vs. 5V). Gate charge values are comparable (480 nC vs. 460 nC), ensuring compatible gate drive requirements.

Q: Why is the IXFK110N07 marked as Not For New Designs?

A: The IXFK110N07 is part of the legacy HiPerFET™ series. The IXFK240N15T2, incorporating both HiPerFET™ and TrenchT2™ technologies, represents the current generation with improved performance and active manufacturing status.

Q: Does the higher input capacitance of the IXFK240N15T2 affect circuit performance?

A: The IXFK240N15T2 exhibits higher input capacitance (32000 pF vs. 9000 pF) due to its higher current and voltage ratings. Gate drive circuits must be evaluated for this parameter, though the comparable gate charge (460 nC vs. 480 nC) indicates similar switching speed characteristics.

Q: Are both devices available in the same packaging options?

A: Yes. Both the IXFK110N07 and IXFK240N15T2 are supplied in TO-264-3 and TO-264AA through-hole packages, ensuring identical PCB footprint and thermal interface compatibility.
