The STF14NM50N from STMicroelectronics provides 500 V operation with 12 A continuous drain current and superior on-resistance of 320 mOhm at 6 A, 10 V. This device is part of the active MDmesh™ II series and carries ROHS3 compliance. The lower on-resistance reduces power dissipation in high-frequency switching applications. Gate charge of 27 nC is lower than the original, improving switching speed.

The STP14NK50Z from STMicroelectronics offers 500 V, 14 A continuous drain current with 380 mOhm on-resistance matching the original specification. This SuperMESH™ series device provides 150 W power dissipation capability and is actively produced with ROHS3 compliance. Higher gate charge (92 nC) requires consideration in gate drive circuit design.

For Voltage-Rated Margin (600 V Operation):

The SIHA12N60E-E3 from Vishay Siliconix and STF13N60M2 from STMicroelectronics both operate at 600 V, providing additional voltage margin for applications subject to transient overvoltage. Both maintain 380 mOhm on-resistance and are actively produced with ROHS3 compliance. These parts are suitable for designs where the original 500 V rating requires additional safety margin.

For Maximum Current and Thermal Performance:

The IRFB17N50LPBF from Vishay Siliconix, IXFP16N50P and IXTP16N50P from IXYS, and R5016FNX from Rohm Semiconductor all provide 16 A continuous drain current at 500 V. These devices offer significantly enhanced thermal performance (50 W to 300 W power dissipation) and are suitable for applications requiring higher current throughput or improved thermal management. All are actively produced with ROHS3 compliance and full -55°C to 150°C operating range.

All recommended substitutes are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8541.29.0095, maintaining regulatory equivalence with the original part.

Frequently Asked Questions (FAQ)

Q: Can the IPA50R380CE be directly replaced with the IPA50R380CEXKSA2?

A: Yes. The IPA50R380CEXKSA2 is the manufacturer-recommended substitute from Infineon Technologies. Both parts share identical electrical specifications including 500 V drain-source voltage, 380 mOhm on-resistance, and 24.8 nC gate charge. The primary difference is the continuous drain current rating of 6.3 A versus 9.9 A. This substitution is valid for applications where the original device was not operating continuously at maximum current. The operating temperature range of -40°C to 150°C covers standard industrial applications.

Q: What is the difference between the 500 V and 600 V rated substitutes?

A: The 600 V rated devices (SIHA12N60E-E3 and STF13N60M2) provide additional voltage margin above the original 500 V specification. These parts are suitable for applications subject to transient overvoltage conditions or where design margin is required. The 500 V rated substitutes (STF14NM50N, STP14NK50Z, IRFB17N50LPBF, IXFP16N50P, IXTP16N50P, R5016FNX) maintain the original voltage rating and are appropriate for applications with stable supply voltages.

Q: How does on-resistance affect device selection?

A: On-resistance (Rds On) directly determines power dissipation and heat generation during operation. The original IPA50R380CE specifies 380 mOhm maximum on-resistance. Substitutes with lower on-resistance values (such as IRFB17N50LPBF at 320 mOhm or STF14NM50N at 320 mOhm) reduce power loss and improve efficiency. Substitutes with equal or slightly higher on-resistance (such as IXFP16N50P and IXTP16N50P at 400 mOhm) are acceptable if thermal management is adequate. On-resistance is measured at specific gate voltage and current conditions and must be compared at equivalent operating points.

Q: What is the significance of gate charge (Qg) in substitution?

A: Gate charge affects switching speed and gate driver circuit requirements. The original IPA50R380CE has 24.8 nC gate charge at 10 V. Substitutes with lower gate charge (STF13N60M2 at 17 nC, STF14NM50N at 27 nC) enable faster switching and reduce gate driver power consumption. Substitutes with higher gate charge (STP14NK50Z at 92 nC, IRFB17N50LPBF at 130 nC) require more robust gate drive circuits but may offer other performance advantages. Gate charge specifications must be verified at the same gate voltage (10 V) for accurate comparison.

Q: Are all substitute parts available in the same package?

A: No. The original IPA50R380CE uses TO-220-FP packaging. Substitute parts are available in various TO-220 configurations including TO-220-3-FP, TO-220F-3, TO-220AB, TO-220FM, and standard TO-220-3. All are through-hole mounted packages with three leads (Gate, Drain, Source). Pin configurations are standard across all TO-220 variants. Physical dimensions may vary slightly between package types, requiring verification of PCB layout compatibility. Thermal performance may differ between package variants due to different lead frame designs.

Q: Which substitutes are currently in active production?

A: The following substitutes are classified as active production parts: IPA50R380CEXKSA2 (Infineon), IRFB17N50LPBF (Vishay Siliconix), IXFP16N50P (IXYS), IXTP16N50P (IXYS), R5016FNX (Rohm Semiconductor), SIHA12N60E-E3 (Vishay Siliconix), STF13N60M2 (STMicroelectronics), STF14NM50N (STMicroelectronics), and STP14NK50Z (STMicroelectronics). The FDPF16N50T from onsemi is classified as obsolete. Active production status ensures long-term availability and supply chain stability.

Q: What are the compliance and regulatory considerations for substitution?

A: All recommended substitute parts are RoHS3 compliant and REACH unaffected, maintaining regulatory equivalence with the original IPA50R380CE. All parts are classified under ECCN EAR99 and HTSUS code 8541.29.0095. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for all parts, indicating no special moisture handling requirements. These certifications ensure that substitution does not introduce regulatory compliance issues in end-use applications.

Q: Can higher current-rated devices (14 A to 16 A) be used in place of the 9.9 A original?

A: Yes. Higher current-rated devices such as STP14NK50Z (14 A), IRFB17N50LPBF (16 A), IXFP16N50P (16 A), IXTP16N50P (16 A), and R5016FNX (16 A) are fully compatible substitutes. These devices maintain or exceed the 500 V voltage specification and meet or exceed the 380 mOhm on-resistance requirement. Higher current ratings provide additional design margin and improved thermal performance. These substitutes are appropriate for applications where enhanced current capability or thermal headroom is beneficial.

Q: What is the operating temperature range compatibility?

A: The original IPA50R380CE operates from -55°C to 150°C. Most substitute parts maintain this full temperature range. The exception is IPA50R380CEXKSA2, which operates from -40°C to 150°C. This reduced lower temperature limit is acceptable for applications not requiring operation below -40°C. All other substitutes support the full -55°C to 150°C range, ensuring compatibility with industrial and automotive temperature specifications.
