Substitute Part Grouping Explanation

Substitute parts for the IXFP90N20X3 are identified based on strict electrical and mechanical parameter matching within the following criteria:

Parametric Equivalents maintain identical or equivalent electrical specifications across all critical parameters: Vdss (200V), Id (90A nominal), Rds On (12.8mOhm @ 45A, 10V), Vgs(th) (4.5V @ 1.5mA), gate charge (78nC @ 10V), maximum gate voltage (±20V), and operating temperature range (-55°C to 150°C). These parts differ only in package configuration (TO-247 vs. TO-220-3) while retaining Through Hole mounting and identical electrical performance.

Similar Substitutes share the same Vdss rating (200V) and package type (TO-220-3) but exhibit variations in continuous drain current (84A vs. 90A), on-state resistance (12mOhm @ 84A vs. 12.8mOhm @ 45A), gate charge (87nC vs. 78nC), input capacitance (6650pF @ 100V vs. 5420pF @ 25V), power dissipation (300W vs. 390W), and maximum operating temperature (175°C vs. 150°C). These parts are suitable for applications where the specified current and power ratings are not exceeded and thermal management accommodates the lower power dissipation ceiling.

All substitute parts maintain RoHS3 compliance, REACH unaffected status, and MSL Level 1 (Unlimited) moisture sensitivity rating.

Engineering Selection Recommendations

IXFH90N20X3 (Parametric Equivalent): This part is the direct electrical equivalent of the IXFP90N20X3, with identical electrical specifications across all critical parameters. The only difference is the package configuration: TO-247-3 versus TO-220-3. Selection of this part is appropriate when PCB layout or thermal management requirements favor the TO-247 package form factor. Both parts are Active in product status, RoHS3 compliant, and REACH unaffected. Inventory availability is comparable (1240 pcs vs. 1216 pcs).

IPP120N20NFDAKSA1 (Similar Substitute): This Infineon OptiMOS™ part shares the same 200V Vdss rating and TO-220-3 package as the main part. However, it operates at 84A continuous drain current versus 90A, with reduced maximum power dissipation (300W vs. 390W). This part is suitable for applications where the design current requirement does not exceed 84A and thermal dissipation remains within 300W limits. The part offers an extended maximum operating temperature of 175°C compared to 150°C. All regulatory compliance certifications (RoHS3, REACH, MSL Level 1) are maintained. Selection of this part requires confirmation that application current and power requirements are compatible with the reduced ratings.

All substitute parts are Active in product status and maintain full regulatory compliance with RoHS3 and REACH requirements.

Frequently Asked Questions (FAQ)

Q: Can the IXFH90N20X3 be used as a direct replacement for the IXFP90N20X3 in existing designs?

A: The IXFH90N20X3 is electrically identical to the IXFP90N20X3 across all specified parameters. The primary difference is the package type: TO-247-3 versus TO-220-3. Direct PCB substitution requires that the TO-247 package footprint is compatible with the existing board layout. Pin configurations and electrical characteristics are equivalent, allowing functional interchangeability when package dimensions are accommodated.

Q: What are the limitations of using the IPP120N20NFDAKSA1 as a substitute?

A: The IPP120N20NFDAKSA1 operates at 84A continuous drain current, compared to the IXFP90N20X3 rating of 90A. Maximum power dissipation is 300W versus 390W. Applications requiring the full 90A current rating or sustained power dissipation above 300W are not suitable for this substitute. The part is appropriate for designs operating within these reduced electrical limits. All other electrical parameters (Vdss, Rds On, gate characteristics, voltage ratings) are compatible.

Q: Are all substitute parts available in the same packaging format?

A: The IXFP90N20X3 and IPP120N20NFDAKSA1 are both supplied in TO-220-3 Through Hole packages. The IXFH90N20X3 is supplied in TO-247-3 Through Hole package. PCB layout compatibility must be confirmed when selecting between TO-220-3 and TO-247-3 packages, as they have different physical dimensions and pin spacing.

Q: Do all parts meet the same regulatory and compliance standards?

A: Yes. The IXFP90N20X3, IXFH90N20X3, and IPP120N20NFDAKSA1 are all RoHS3 compliant, REACH unaffected, and rated MSL Level 1 (Unlimited moisture sensitivity). All parts are classified under ECCN EAR99 and HTSUS 8541.29.0095.

Q: What is the difference in gate charge between the main part and the Infineon substitute?

A: The IXFP90N20X3 has a maximum gate charge of 78nC at 10V, while the IPP120N20NFDAKSA1 has 87nC at 10V. This 9nC difference may affect gate drive circuit design and switching speed characteristics. Applications with tight gate drive timing requirements should account for this parameter variation.

Q: Can the IPP120N20NFDAKSA1 operate at higher temperatures than the main part?

A: Yes. The IPP120N20NFDAKSA1 has a maximum operating temperature of 175°C, compared to 150°C for the IXFP90N20X3. However, this extended temperature capability does not compensate for the reduced power dissipation rating (300W vs. 390W). Thermal management design must still respect the 300W maximum power dissipation limit.
