Engineering Selection Recommendations

Active Status Parts (Recommended for New Designs):

IRFR1018ETRPBF (Infineon HEXFET®) is the primary substitute for applications requiring equivalent or higher current capability. This part maintains 60V Vdss rating with 56A continuous drain current and identical 8.4mOhm on-resistance at comparable gate charge. Full operating temperature range (-55°C to 175°C) and ROHS3 compliance are maintained. Inventory availability is 25,300 units.

DMTH6010LK3-13, DMTH6010SK3-13, and DMTH6010SK3Q-13 (Diodes Incorporated) provide 60V/70A capability with 8mOhm on-resistance, exceeding the IXTY90N055T2 current specification. DMTH6010SK3Q-13 carries AEC-Q101 automotive qualification for applications requiring automotive-grade components. All variants maintain full temperature range and ROHS3 compliance.

DMTH6009LK3-13 (Diodes Incorporated) offers 60V/59A operation with 10mOhm on-resistance. This part is suitable for applications where the 90A specification can be reduced to 59A continuous drain current.

Not For New Designs:

IRFR48ZTRLPBF (Infineon) carries "Not For New Designs" status. While electrically compatible at 55V/42A, this part should not be selected for new circuit designs. Existing designs currently using this part may continue operation, but migration to active-status alternatives is recommended for long-term supply security.

Packaging Considerations:

All substitute parts are available in TO-252-3 (DPAK) surface mount configuration, maintaining mechanical compatibility with the IXTY90N055T2 footprint. Packaging variants (Tape & Reel, Cut Tape, Digi-Reel®) are available across the substitute family to accommodate different procurement and assembly requirements.

Frequently Asked Questions (FAQ)

Q: Can IRFR1018ETRPBF directly replace IXTY90N055T2 in all applications?

A: IRFR1018ETRPBF is electrically compatible for applications operating at or below 55V. The 60V Vdss rating provides additional voltage margin. The 56A continuous drain current is lower than the IXTY90N055T2's 90A specification; verify that your application current requirements do not exceed 56A at Tc. On-resistance (8.4mOhm) and gate charge (69nC) are comparable. Both parts share identical operating temperature range and RoHS3 compliance.

Q: What is the difference between DMTH6010LK3-13 and DMTH6010SK3-13?

A: Both parts share identical electrical specifications: 60V Vdss, 70A continuous drain current, and 8mOhm on-resistance. The primary difference is gate threshold voltage: DMTH6010LK3-13 specifies 3V while DMTH6010SK3-13 specifies 4V at 250µA. DMTH6010SK3-13 gate charge is lower (36.3nC vs. 41.3nC). Select based on gate drive circuit requirements and switching speed optimization.

Q: Are DMTH6010LK3Q-13 and DMTH6010SK3Q-13 suitable for automotive applications?

A: DMTH6010LK3Q-13 and DMTH6010SK3Q-13 both carry AEC-Q101 automotive qualification. DMTH6010SK3Q-13 is explicitly listed with "Automotive" grade designation. Both parts meet automotive reliability and qualification standards. Verify specific automotive application requirements with your design team before selection.

Q: Why does DMTH6009LK3-13 show lower power dissipation than IXTY90N055T2?

A: Power dissipation values reflect thermal performance under specified test conditions (Ta vs. Tc). DMTH6009LK3-13 lists 2.6W (Ta) and 60W (Tc), while IXTY90N055T2 lists 150W (Tc). These differences result from package thermal characteristics and measurement methodology. Verify thermal performance through detailed datasheet thermal resistance (Rθ) specifications for your specific application thermal environment.

Q: Can I use DMTH6009LK3-13 if my application requires 90A continuous current?

A: No. DMTH6009LK3-13 is rated for 57A continuous drain current at Tc, which is below the IXTY90N055T2's 90A specification. Using this part in an application requiring 90A would exceed the device's continuous current rating and result in thermal stress and potential failure. Select DMTH6010 series parts (70A rating) or IRFR1018ETRPBF (56A rating) only if your actual application current requirement is within the part's specification.

Q: What is the significance of the "TrenchT2™" series designation for IXTY90N055T2?

A: TrenchT2™ is IXYS's proprietary trench technology for MOSFET construction. This technology designation does not affect substitution compatibility. Substitute parts from Infineon (HEXFET®) and Diodes Incorporated use different manufacturing technologies but achieve equivalent electrical performance through their respective process technologies. Technology designation is informational only and does not restrict substitution based on electrical parameters.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed in this document carry ROHS3 Compliant status, matching the IXTY90N055T2 compliance level. All parts are also REACH Unaffected and carry EAR99 ECCN classification with identical HTSUS code (8541.29.0095).
