Equivalent & Substitute Parts for IPA80R310CEXKSA2

Part Overview

The IPA80R310CEXKSA2 is an N-Channel 800V 16.7A MOSFET manufactured by Infineon Technologies, part of the CoolMOS™ series. This through-hole device in TO-220-FP packaging is designed for high-voltage switching applications requiring robust performance across industrial and power conversion systems. The part is currently in active production status with 1013 units in stock.

Substitute parts become necessary when the primary component experiences supply constraints, extended lead times, or when design flexibility permits operation at reduced voltage or current ratings while maintaining system functionality. The substitute devices listed below provide equivalent or reduced-specification alternatives suitable for applications where the full 800V rating is not required.

Substitute Part Grouping Explanation

Substitution eligibility for the IPA80R310CEXKSA2 is determined by the following criteria:

Mandatory Compatibility Parameters:

• Mounting Type: Through Hole (all substitutes must match)
• Package Case: TO-220-3 Full Pack (all substitutes must match)
• FET Type: N-Channel (all substitutes must match)
• Technology: MOSFET Metal Oxide (all substitutes must match)
• Gate Drive Voltage: 10V (all substitutes must match)
• Maximum Gate Voltage (Vgs Max): ±20V or higher (all substitutes must meet or exceed)

Allowable Parameter Variations:

• Drain to Source Voltage (Vdss): May be reduced from 800V to 600V or 650V for applications not requiring full voltage rating
• Continuous Drain Current (Id): May be reduced from 16.7A to 10.2A, 11A, or 12A depending on application current requirements
• On-State Resistance (Rds On): May vary within acceptable thermal and efficiency margins
• Gate Charge (Qg): May be reduced, indicating improved switching performance
• Power Dissipation: May be reduced if thermal design accommodates lower rating
• Operating Temperature: May be extended or maintained within specified range

All substitute parts listed maintain through-hole TO-220-3 packaging and N-Channel MOSFET technology, ensuring mechanical and electrical interface compatibility with the original design.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute - STF16N60M2 (STMicroelectronics): This part is the preferred substitute when voltage derating from 800V to 600V is acceptable. It offers the lowest on-state resistance at 320mOhm, lowest gate charge at 19nC, and lowest input capacitance at 700pF among all substitutes. The device maintains active product status, ROHS3 compliance, and provides superior switching characteristics. Current rating of 12A accommodates most applications designed for the original 16.7A device. Inventory availability is 1335 units.

Secondary Substitute - STF15NM65N (STMicroelectronics): This part provides the highest voltage rating among substitutes at 650V, offering a compromise between the original 800V and the 600V alternatives. It maintains 12A continuous current and delivers balanced performance with 380mOhm on-state resistance and 33.3nC gate charge. Active product status and ROHS3 compliance are confirmed. Inventory availability is 15436 units, providing superior supply security.

Tertiary Substitute - FCPF380N60 (Fairchild Semiconductor): This device operates at 600V with 10.2A continuous current, representing the most significant derating in current capacity. It provides 380mOhm on-state resistance and 40nC gate charge. Active product status is confirmed. This option is suitable only for applications where current requirements do not exceed 10.2A. Inventory availability is 2055 units.

Not Recommended - STFH13N60M2 (STMicroelectronics): This part carries obsolete product status and should not be selected for new designs or long-term production applications. Although it maintains ROHS3 compliance and provides 11A continuous current at 600V, the obsolete designation indicates discontinued manufacturing and potential future supply unavailability.

Frequently Asked Questions (FAQ)

Q: Can I use a 600V rated MOSFET in place of the 800V IPA80R310CEXKSA2?

A: Yes, provided your application circuit operates at or below 600V. The 600V substitutes (STF16N60M2, FCPF380N60, STFH13N60M2) are electrically and mechanically compatible with the original design. However, you must verify that your maximum operating voltage does not exceed 600V under any condition, including transient overvoltage events. The 650V option (STF15NM65N) provides additional margin if your circuit operates between 600V and 650V.

Q: What is the impact of using a substitute with lower continuous current rating?

A: The substitute must support your application's maximum continuous drain current. If your design requires 16.7A but the substitute is rated for 12A or 10.2A, thermal analysis must confirm that actual operating current remains below the substitute's rating. Operating above the rated current causes excessive junction temperature rise and reduces device reliability. Verify actual current draw in your specific application before substitution.

Q: Are all substitute parts pin-compatible with the original IPA80R310CEXKSA2?

A: Yes. All listed substitutes use the TO-220-3 Full Pack package with identical pin configuration (Gate, Drain, Source). No PCB layout modifications are required for mechanical installation. However, electrical performance differences may require circuit validation, particularly regarding switching speed and thermal dissipation.

Q: Which substitute offers the best switching performance?

A: The STF16N60M2 provides the lowest gate charge (19nC) and lowest input capacitance (700pF), resulting in faster switching transitions and reduced switching losses. The STF15NM65N offers the second-best switching performance with 33.3nC gate charge and 983pF input capacitance. These characteristics are beneficial in high-frequency switching applications.

Q: What is the difference between active and obsolete product status?

A: Active products are in current production with guaranteed availability and manufacturer support. Obsolete products have been discontinued and are no longer manufactured. The STFH13N60M2 is obsolete, meaning existing inventory will eventually deplete with no replenishment. For new designs or production quantities, select only active-status parts: STF16N60M2, STF15NM65N, or FCPF380N60.

Q: Do all substitutes meet RoHS3 compliance?

A: The STMicroelectronics parts (STF15NM65N, STF16N60M2, STFH13N60M2) are confirmed ROHS3 compliant. The Fairchild FCPF380N60 does not specify RoHS compliance in the provided data. If RoHS3 compliance is a requirement for your application, select only the STMicroelectronics options.

Q: Can I use multiple substitute parts interchangeably in the same design?

A: All substitutes are mechanically and electrically compatible for installation purposes. However, they exhibit different electrical characteristics (Rds On, Qg, Ciss). If your design includes multiple MOSFETs, using identical part numbers ensures consistent performance and thermal behavior. Mixing different substitute types may result in uneven current distribution or thermal imbalance in parallel configurations.
