IPA60R299CPXKSA1 Equivalent & Substitute Parts

Part Overview

The IPA60R299CPXKSA1 is an N-Channel 600V 11A MOSFET manufactured by Infineon Technologies in the CoolMOS™ series, housed in a TO-220-3 Full Pack through-hole package. This device is classified as "Not For New Designs," indicating it has reached end-of-life status. The part delivers 33W maximum power dissipation and features a 299mOhm on-resistance at specified conditions, making it suitable for power conversion and switching applications requiring 600V blocking capability.

Due to its discontinued status, equivalent and substitute parts from active manufacturers are necessary for ongoing production support, design refreshes, and inventory replenishment. Substitute selection must maintain compatibility across drain-source voltage, continuous drain current, on-resistance characteristics, and through-hole TO-220 packaging.

Substitute Part Grouping Explanation

Substitute parts for the IPA60R299CPXKSA1 are selected based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

Drain-Source Voltage (Vdss): 600V minimum (allows higher voltage ratings as they maintain backward compatibility)
Continuous Drain Current (Id): 11A minimum at 25°C
On-Resistance (Rds On): Comparable to 299mOhm to maintain thermal and efficiency characteristics
Package Type: TO-220-3 Full Pack through-hole configuration
FET Type: N-Channel MOSFET technology
Operating Temperature: -55°C to 150°C minimum range

Substitution Logic: Parts are grouped into two categories based on voltage rating alignment:

Category 1 – 600V Rated Devices: Direct voltage equivalents offering comparable or improved on-resistance performance. These include FCPF380N60 (Fairchild), R6011ENX and R6015ENX (Rohm), SIHF15N60E-GE3 (Vishay), and STF13NM60ND and STF18N60M2 (STMicroelectronics). These maintain the exact voltage specification of the original part.

Category 2 – 800V Rated Devices: Higher voltage-rated alternatives that provide enhanced voltage margin while maintaining or improving current and on-resistance specifications. These include STFU13N80K5 and STF11NM80 (STMicroelectronics). The elevated voltage rating does not compromise application compatibility in 600V circuits.

All substitute parts maintain through-hole TO-220 packaging, RoHS3 compliance, and active product status from established semiconductor manufacturers.

Engineering Selection Recommendations

For Direct Replacement (Highest Compatibility):

STF13NM60ND and STF18N60M2 from STMicroelectronics are recommended as primary substitutes. Both maintain the 600V voltage specification, deliver active product status, and provide RoHS3 compliance. STF13NM60ND matches the 11A current rating exactly, while STF18N60M2 offers improved on-resistance (280mOhm) with 13A capability. Both are available in TO-220FP packaging with full thermal and electrical compatibility.

For Applications Requiring Enhanced Voltage Margin:

STFU13N80K5 and STF11NM80 (STMicroelectronics) provide 800V blocking capability while maintaining 11-12A current ratings. These parts are suitable for circuits where higher voltage transient immunity is beneficial. Both carry active status and RoHS3 compliance.

For Improved On-Resistance Performance:

R6015ENX (Rohm) and SIHF15N60E-GE3 (Vishay) deliver superior on-resistance characteristics (290mOhm and 280mOhm respectively) at 15A continuous current, reducing thermal dissipation in power-dense applications. Both maintain 600V specification and active product status.

For Fairchild-Based Supply Chains:

FCPF380N60 provides 600V/10.2A capability in SuperFET® II series with active status. On-resistance of 380mOhm is slightly elevated compared to the original part but remains within acceptable thermal margins for most applications.

All recommended substitutes are manufactured by established semiconductor suppliers with active product lines, ensuring long-term availability and supply chain stability.

Frequently Asked Questions (FAQ)

Q1: Can I use an 800V-rated MOSFET as a direct replacement for the 600V IPA60R299CPXKSA1?

A: Yes. Higher voltage-rated MOSFETs (STFU13N80K5, STF11NM80) function as direct replacements in 600V circuits. The elevated voltage rating provides additional transient margin without compromising performance. All electrical parameters remain compatible with the original application.

Q2: What is the significance of on-resistance (Rds On) when selecting a substitute?

A: On-resistance directly determines power dissipation and thermal performance. The IPA60R299CPXKSA1 specifies 299mOhm maximum. Substitutes with comparable or lower on-resistance (such as STF18N60M2 at 280mOhm or R6015ENX at 290mOhm) deliver equal or improved efficiency. Higher on-resistance values increase heat generation and may require thermal design review.

Q3: Are all substitute parts available in the same TO-220 package?

A: All listed substitutes use TO-220-3 Full Pack through-hole configuration. Minor package variants exist (TO-220FP, TO-220FM, TO-220F-3, TO-220 Isolated Tab), but all are mechanically and electrically compatible with standard TO-220 PCB footprints and heatsink mounting hardware.

Q4: Why is the IPA60R299CPXKSA1 marked "Not For New Designs"?

A: This designation indicates the part has reached end-of-life status at Infineon. New designs should incorporate active alternatives. Existing production lines may continue using available inventory, but long-term supply cannot be guaranteed. Substitution to active parts ensures design sustainability.

Q5: Do all substitute parts meet RoHS3 compliance?

A: All recommended substitutes carry RoHS3 Compliant certification. This ensures compatibility with environmental regulations and procurement requirements. Compliance status is verified in the parameter comparison table.

Q6: What is the difference between gate charge (Qg) specifications, and does it affect substitution?

A: Gate charge determines the energy required to switch the MOSFET on and off. Lower gate charge (such as IXFP12N65X2M at 18.5nC) reduces driver power consumption and switching losses. Higher gate charge (such as SIHF15N60E-GE3 at 78nC) may require more robust gate drive circuits. Selection depends on driver capability and switching frequency requirements.

Q7: Can I substitute parts with different continuous current ratings?

A: Yes, provided the substitute current rating meets or exceeds the application requirement. Parts rated for 13A or 15A (STF18N60M2, R6015ENX, SIHF15N60E-GE3) are suitable replacements for 11A applications. The higher rating provides current margin without performance degradation. Conversely, substituting with lower-rated parts (such as FCPF380N60 at 10.2A) requires thermal and current-density verification.

Q8: What packaging considerations apply to through-hole TO-220 MOSFETs?

A: All substitute parts use through-hole TO-220 mounting, compatible with standard PCB footprints. Isolated tab variants (IXFP12N65X2M) provide electrical isolation between the tab and drain, beneficial in certain topologies. Standard tab designs (TO-220FP, TO-220FM) connect the tab to the drain internally. Verify heatsink mounting requirements and electrical isolation needs before selection.

Q9: Which substitute offers the best balance of performance and availability?

A: STF18N60M2 and STF18NM60N (STMicroelectronics) provide optimal balance: 600V specification, 13A current capability, superior on-resistance (280-285mOhm), active product status, and extensive inventory availability (68,007 and 15,522 units respectively). Both are suitable for immediate production deployment.

Q10: Are there supply chain advantages to selecting specific manufacturers?

A: STMicroelectronics substitutes (STFU13N80K5, STF11NM80, STF13NM60ND, STF18N60M2, STF18NM60N) offer the highest inventory levels (5,100 to 68,007 units), ensuring supply continuity. Rohm (R6011ENX, R6015ENX) and Vishay (SIHF15N60E-GE3) provide alternative sources for supply chain diversification. IXYS (IXFP12N65X2M) and Fairchild (FCPF380N60) offer specialized performance characteristics for specific application requirements.
