IXKP24N60C5M N-Channel 600V 8.5A MOSFET Equivalent & Substitute Parts

Part Overview

The IXKP24N60C5M is an N-Channel 600V MOSFET manufactured by IXYS in the CoolMOS™ series, housed in a TO-220ABFP through-hole package. This device is rated for 8.5A continuous drain current at 25°C and features a maximum drain-to-source voltage of 600V. The part is currently in active production status with 1047 units in stock.

Substitute parts are necessary when the original IXKP24N60C5M becomes unavailable, when alternative sourcing is required for supply chain optimization, or when design flexibility permits selection from functionally equivalent alternatives. Substitute devices must maintain compatibility across critical electrical parameters including voltage rating, current capacity, gate charge characteristics, and thermal operating range.

Substitute Part Grouping Explanation

Substitution eligibility for the IXKP24N60C5M is determined by the following critical parameters:

Voltage Rating Compatibility: All substitute parts must maintain a drain-to-source voltage (Vdss) rating of 600V or higher. Parts rated at 650V are acceptable as they provide equivalent or superior voltage withstand capability.

Current Rating Consideration: While the IXKP24N60C5M is rated for 8.5A continuous drain current, substitute parts with higher current ratings (18A to 24A) are functionally compatible in applications where the original 8.5A specification is not fully utilized. Lower-rated substitutes are not acceptable.

On-State Resistance (Rds On): Substitute parts must have Rds On values within the range of 150–200 mOhm at the specified gate voltage (10V) and measurement current. This parameter directly affects power dissipation and thermal performance.

Gate Charge (Qg): Gate charge values between 19.8 nC and 82 nC are acceptable, as these variations reflect different switching speed characteristics while maintaining functional compatibility.

Gate Threshold Voltage (Vgs(th)): Acceptable threshold voltages range from 3.5V to 5V, ensuring reliable gate drive compatibility with standard 10V gate drive circuits.

Package Type: All substitute parts must use through-hole mounting in TO-220 family packages (TO-220ABFP, TO-220F, TO-220FM, TO-220FP, or equivalent full-pack variants).

Operating Temperature Range: All substitute parts must support the full -55°C to 150°C operating temperature range.

Compliance Status: All substitute parts must be RoHS3 compliant and REACH unaffected.

Engineering Selection Recommendations

Active Status Substitutes (Recommended for New Designs):

The following substitute parts carry active product status and are suitable for new design implementations:

FCP170N60 (Fairchild Semiconductor) provides a 22A current rating with 170 mOhm on-state resistance and matches the original 3.5V gate threshold voltage. This part maintains full compatibility with the IXKP24N60C5M electrical specifications while offering higher current capacity.

R6024ENX (Rohm Semiconductor) delivers 24A continuous drain current with 165 mOhm on-state resistance, identical to the original part's Rds On specification. This device is available in high inventory (150,300 units) and maintains full RoHS3 compliance.

STF24N60DM2 (STMicroelectronics) offers 18A current rating with 200 mOhm on-state resistance and is actively produced. This part is suitable for applications where the original 8.5A specification provides design margin.

STF26NM60N (STMicroelectronics) provides 20A continuous drain current with 165 mOhm on-state resistance, matching the original Rds On value. This device is available in substantial inventory (107,606 units).

STF28N60M2 (STMicroelectronics) delivers 24A current rating with 150 mOhm on-state resistance, the lowest Rds On value among all substitutes, resulting in reduced power dissipation. This part is actively produced and RoHS3 compliant.

Not For New Designs Substitutes (Legacy/Replacement Only):

AOTF20S60L, FCPF190N60, FCPF190N60E, IPAW60R180P7SXKSA1, and STF28NM60ND carry "Not For New Designs" status and are suitable only for replacement of existing installations or when supply constraints require legacy part selection. These parts maintain full electrical compatibility but should not be selected for new product development.

Voltage Rating Consideration:

IPAW60R180P7SXKSA1 (Infineon Technologies) is rated at 650V, providing 50V additional voltage margin over the original 600V specification. This part is suitable for applications requiring enhanced voltage headroom, though it carries "Not For New Designs" status.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a higher current rating than the original IXKP24N60C5M?

A: Yes. Substitute parts with current ratings of 18A, 20A, 22A, 23A, or 24A are functionally compatible with the original 8.5A specification. The higher current rating indicates the device can safely handle greater current without exceeding thermal limits. In applications where the original 8.5A rating is not fully utilized, higher-rated substitutes provide equivalent or superior performance.

Q: What is the significance of on-state resistance (Rds On) variation among substitute parts?

A: On-state resistance directly determines power dissipation during conduction. The IXKP24N60C5M specifies 165 mOhm. Substitute parts range from 150 mOhm to 200 mOhm. Lower Rds On values (150 mOhm in STF28N60M2 and STF28NM60ND) result in reduced power dissipation and lower junction temperature. Higher values (200 mOhm in STF24N60DM2 and FCPF190N60) increase power dissipation but remain within acceptable operating limits for most applications.

Q: Are all substitute parts available in the same TO-220ABFP package?

A: No. While all substitute parts use through-hole TO-220 family packages, specific variants differ: TO-220F, TO-220FM, TO-220FP, and PG-TO220. These packages are mechanically and electrically compatible for standard through-hole PCB mounting. Pin configurations remain identical (Gate, Drain, Source). Verify PCB footprint compatibility with the specific package variant selected.

Q: What does "Not For New Designs" status mean for substitute parts?

A: "Not For New Designs" indicates the manufacturer has discontinued active development and marketing of that part number. These parts remain available in inventory and are functionally equivalent to active alternatives. They are suitable for replacement of existing installations or when supply constraints require their selection. For new product development, prioritize parts with "Active" status to ensure long-term availability and manufacturer support.

Q: Can I substitute the IXKP24N60C5M with a 650V-rated device like the IPAW60R180P7SXKSA1?

A: Yes. The IPAW60R180P7SXKSA1 is rated at 650V, providing 50V additional voltage margin. This part is electrically compatible and suitable for applications where enhanced voltage headroom is beneficial. However, this part carries "Not For New Designs" status. For new designs requiring higher voltage rating, consult active-status alternatives or contact manufacturers for current 650V offerings.

Q: How do gate charge (Qg) differences affect circuit performance?

A: Gate charge values range from 19.8 nC to 82 nC among substitutes. Lower gate charge (AOTF20S60L at 19.8 nC) enables faster switching with reduced gate drive power requirements. Higher gate charge (FCPF190N60E at 82 nC) requires more gate drive energy but may provide improved noise immunity. Both extremes are compatible with standard 10V gate drive circuits. Select based on switching frequency requirements and gate drive circuit capability.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed carry RoHS3 compliance certification. All are also REACH unaffected. This ensures compatibility with environmental and regulatory requirements equivalent to the original IXKP24N60C5M.

Q: What is the impact of input capacitance (Ciss) variation?

A: Input capacitance ranges from 1038 pF to 3175 pF among substitutes. Higher input capacitance increases gate charge requirements and may slow switching speed in circuits with limited gate drive current. Lower input capacitance (AOTF20S60L at 1038 pF) enables faster switching transitions. Select based on circuit switching frequency and gate drive circuit design. All values are compatible with standard gate drive topologies.

Q: Which substitute part offers the best thermal performance?

A: STF28N60M2 offers the lowest on-state resistance at 150 mOhm, resulting in the lowest power dissipation and junction temperature rise during conduction. For applications with stringent thermal constraints, this part provides superior thermal performance while maintaining full electrical compatibility with the IXKP24N60C5M.
