IXKP24N60C5 N-Channel 600V 24A MOSFET Equivalent & Substitute Parts

Part Overview

The IXKP24N60C5 is an N-Channel 600V 24A MOSFET manufactured by IXYS in the CoolMOS™ series, housed in a TO-220-3 through-hole package. This device is designated as Last Time Buy, indicating end-of-life status. The part operates across a temperature range of -55°C to 150°C and is RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Equivalent and substitute parts are necessary due to the Last Time Buy status of the IXKP24N60C5. Alternative devices with comparable electrical and mechanical specifications ensure design continuity and supply chain reliability for applications requiring N-Channel MOSFETs with 600V drain-source voltage capability and 24A continuous drain current ratings.

Substitute Part Grouping Explanation

Substitution of the IXKP24N60C5 is determined by the following critical parameters:

Primary Substitution Criteria:

Drain to Source Voltage (Vdss): 600V minimum (allows 650V rated devices)
Continuous Drain Current (Id): 24A minimum at 25°C
Package Type: TO-220-3 through-hole configuration
FET Type: N-Channel Metal Oxide MOSFET
Operating Temperature Range: -55°C to 150°C minimum
Gate Voltage Rating (Vgs): ±20V minimum

Secondary Compatibility Factors:

Engineering Selection Recommendations

Primary Recommendation: IXTP24N65X2

The IXTP24N65X2 is the manufacturer-recommended upgrade from IXYS. This device maintains identical 24A continuous drain current and TO-220-3 package configuration while offering improved electrical characteristics: 650V Vdss rating (50V margin above the original 600V), reduced Rds On of 145 mOhm (versus 165 mOhm), and lower gate charge of 36 nC (versus 52 nC). The part is in Active product status with 4200 units in stock. RoHS3 compliance and MSL 1 rating match the original specification. The higher Vgs(Max) of ±30V provides additional design margin.

Secondary Recommendation: IPP60R160P6XKSA1

The IPP60R160P6XKSA1 from Infineon Technologies is a direct equivalent with 600V Vdss and 23.8A continuous drain current (within 1% of the original 24A specification). This CoolMOS™ P6 device maintains identical package and thermal operating range. Rds On of 160 mOhm is comparable to the original 165 mOhm. The part is in Active status with 1286 units available. RoHS3 compliance and MSL 1 rating are confirmed.

Tertiary Recommendation: AOT25S65L

The AOT25S65L from Alpha & Omega Semiconductor Inc. provides 25A continuous drain current at 650V Vdss in TO-220-3 package. This device is in Active product status with 1506 units in stock. While Rds On is slightly higher at 190 mOhm, the additional current margin (25A versus 24A) and voltage margin (650V versus 600V) provide design flexibility. RoHS3 compliance and MSL 1 rating are confirmed.

Not Recommended for New Designs:

Parts with "Not For New Designs" or "Obsolete" status (AOT20S60L, AOT27S60L, FCP190N60E, FCP22N60N, IPP60R190C6XKSA1) should not be selected for new circuit designs despite electrical compatibility. These designations indicate manufacturer discontinuation plans or end-of-life status.

Frequently Asked Questions (FAQ)

Q: Can the IXTP24N65X2 directly replace the IXKP24N60C5 without circuit modifications?

A: Yes. The IXTP24N65X2 maintains identical 24A continuous drain current, TO-220-3 package, and -55°C to 150°C operating temperature range. The 650V Vdss rating is a higher specification that does not require circuit changes. Gate drive voltage requirements are compatible (±30V maximum versus ±20V original). No PCB layout modifications are necessary.

Q: What is the significance of the Rds On parameter in substitution?

A: Rds On (on-state drain-source resistance) directly affects power dissipation and thermal performance. Lower Rds On values reduce heat generation at the same current level. The IXTP24N65X2 offers 145 mOhm versus the original 165 mOhm, resulting in approximately 12% lower conduction losses. Substitutes with higher Rds On values (such as AOT25S65L at 190 mOhm) require thermal analysis to confirm adequate heat dissipation in the application.

Q: Why are some substitute parts listed as "Not For New Designs"?

A: Manufacturers designate parts as "Not For New Designs" when discontinuation is planned. While these parts may be electrically compatible, they represent supply chain risk. New designs should use parts with "Active" product status to ensure long-term availability and manufacturer support.

Q: Does the TO-220-3 package designation guarantee mechanical compatibility?

A: Yes. All listed substitute parts use the TO-220-3 through-hole package, ensuring identical pin configuration, lead spacing, and PCB footprint compatibility. No mechanical redesign is required. However, thermal management considerations (heatsink requirements) may differ based on power dissipation characteristics.

Q: What is the impact of gate charge (Qg) differences on circuit performance?

A: Gate charge affects switching speed and gate drive circuit requirements. Lower Qg values (such as IXTP24N65X2 at 36 nC versus original 52 nC) reduce switching losses and allow faster switching transitions. Higher Qg values (such as FCP190N60E at 82 nC) require longer gate drive pulse widths but do not prevent substitution if the gate driver circuit has adequate current capability.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All recommended substitute parts carry RoHS3 Compliant certification, matching the original IXKP24N60C5 specification. REACH compliance status is confirmed as "REACH Unaffected" for all listed alternatives.

Q: What is the MSL (Moisture Sensitivity Level) rating, and why does it matter?

A: MSL 1 (Unlimited) indicates the component can be stored indefinitely without moisture absorption concerns and requires no special handling or baking procedures before soldering. All listed substitute parts maintain MSL 1 rating, ensuring identical moisture management requirements.

Q: Can I use the IPP60R180P7XKSA1 if my application requires 24A continuous current?

A: No. The IPP60R180P7XKSA1 is rated for 18A continuous drain current, which is 25% below the original 24A specification. This device is suitable only for applications with lower current requirements. Use IXTP24N65X2, IPP60R160P6XKSA1, or AOT25S65L for 24A or higher current applications.

Q: What is the difference between Vdss and Vgs(Max) ratings?

A: Vdss (Drain-Source Voltage) is the maximum voltage that can be applied between drain and source terminals. Vgs(Max) is the maximum voltage that can be applied to the gate terminal relative to source. Both ratings must be respected in circuit design. The IXTP24N65X2 offers higher margins in both parameters (650V Vdss and ±30V Vgs(Max)) compared to the original (600V Vdss and ±20V Vgs(Max)).
