IXTP220N04T2 Equivalent & Substitute Parts

Part Overview

The IXTP220N04T2 is an N-Channel MOSFET manufactured by IXYS, rated for 40V drain-to-source voltage with 220A continuous drain current at 25°C. This device is part of the TrenchT2™ series and is housed in a TO-220-3 through-hole package. The part is currently in active production status and is RoHS3 compliant.

Substitute parts are necessary when the IXTP220N04T2 becomes unavailable, when alternative manufacturers are required for supply chain diversification, or when design requirements permit operation within the electrical and mechanical parameters of equivalent devices. Substitutes must maintain compatibility with the TO-220-3 through-hole mounting footprint and operate within the specified voltage and current ratings.

Engineering Selection Recommendations

Primary Substitutes (Active Status, Through-Hole TO-220-3 Package):

CSD18502KCS (Texas Instruments NexFET™ series) is the most suitable substitute for the IXTP220N04T2. This device maintains the TO-220-3 through-hole package, operates at 40V Vdss, and delivers 100A continuous drain current. While the current rating is lower than the IXTP220N04T2, the CSD18502KCS provides superior on-resistance characteristics (2.9 mOhm @ 100A, 10V) and lower gate charge (62 nC @ 10V), resulting in improved efficiency in switching applications. The part is in active production status with RoHS3 compliance.

Secondary Substitutes (Through-Hole TO-220 Variants):

IRFB7446PBF (Infineon HEXFET® StrongIRFET™ series) operates at 40V Vdss with 120A continuous drain current in a TO-220AB through-hole package. This device is in active production status and RoHS3 compliant. The on-resistance of 3.3 mOhm @ 70A, 10V is comparable to the IXTP220N04T2, making it suitable for applications where the 220A rating is not fully utilized.

IRL1404ZPBF (Infineon HEXFET® series) provides 75A continuous drain current at 40V Vdss in a TO-220AB through-hole package. This device is in active production status with RoHS3 compliance. The on-resistance of 3.1 mOhm @ 75A, 10V and power dissipation of 230W (Tc) make it suitable for lower-current applications.

Not Recommended for New Designs:

AOT240L (Alpha & Omega Semiconductor Inc.) is marked as "Not For New Designs" and should not be selected for new circuit implementations, despite electrical compatibility.

IRL40B215 and PSMN2R8-40PS,127 are obsolete products and should not be used in new designs.

AUIRF1404ZSTRL is a surface-mount D2PAK device and is not compatible with through-hole TO-220-3 footprints.

Frequently Asked Questions (FAQ)

Q: Can the AUIRF1404ZSTRL be used as a substitute for the IXTP220N04T2?

A: No. Although the AUIRF1404ZSTRL meets the electrical specifications (40V Vdss, 160A continuous drain current), it uses a surface-mount TO-263AB (D2PAK) package, which is not compatible with through-hole TO-220-3 PCB footprints. Package compatibility is a mandatory requirement for direct substitution.

Q: What is the difference between TO-220-3 and TO-220AB packages?

A: Both are through-hole packages with identical pin configurations and footprints. TO-220AB is a variant designation used by some manufacturers. Devices in either package can be used interchangeably on the same PCB layout.

Q: Why does the CSD18502KCS have a lower continuous drain current (100A) than the IXTP220N04T2 (220A)?

A: The CSD18502KCS is rated for 100A continuous drain current at 25°C case temperature. The IXTP220N04T2 is rated for 220A under the same conditions. If the application requires the full 220A capability, the CSD18502KCS is not suitable. However, for applications operating below 100A, the CSD18502KCS offers superior on-resistance and lower gate charge, resulting in lower power dissipation and faster switching.

Q: Are all substitute parts RoHS3 compliant?

A: All recommended active-status substitutes (CSD18502KCS, IRFB7446PBF, IRL1404ZPBF) are RoHS3 compliant. The IXTP220N04T2 is also RoHS3 compliant. Obsolete and "Not For New Designs" parts should not be used regardless of compliance status.

Q: Can I use an obsolete part as a temporary substitute?

A: Obsolete parts (IRL40B215, PSMN2R8-40PS,127) should not be used in any new or existing designs. Obsolescence indicates that the manufacturer has discontinued production and support. Use only active-status parts for reliable long-term operation.

Q: What does "Not For New Designs" mean for the AOT240L?

A: "Not For New Designs" indicates that the manufacturer (Alpha & Omega Semiconductor Inc.) has designated this part for legacy applications only. New circuit designs should not incorporate this device. Use active-status alternatives instead.

Q: How do I determine if a substitute part will work in my application?

A: Verify that the substitute part meets all mandatory parameters: 40V Vdss, N-Channel MOSFET, through-hole TO-220-3 package, and -55°C to 175°C operating temperature range. Confirm that the continuous drain current rating meets or exceeds your application's maximum current requirement. Compare on-resistance and gate charge characteristics to ensure switching performance is acceptable.
