Engineering Selection Recommendations

All parts (APT11F80B, IXFH10N80P, STW9N80K5) are active, RoHS3 compliant, REACH unaffected, and have unlimited moisture sensitivity (MSL 1). ECCN status is EAR99 for each part number. Packaging and through-hole mounting are standardized as TO-247-3 for cross-compatibility. Selection can be made using these certifications and compliance statuses without additional criteria.

Frequently Asked Questions (FAQ)

Q: What primary electrical specifications must match for MOSFET substitution?
A: Allowed parameters for substitution include drain-to-source voltage (Vdss), continuous drain current (Id), Rds On, gate threshold voltage (Vgs(th)), gate charge (Qg), and maximum allowed gate-source voltage (Vgs).

Q: Are substitute MOSFETs required to have the same package type?
A: Yes. Substitution is based only on parts supplied in TO-247-3 packages with through-hole mounting as specified.

Q: Is RoHS and REACH compliance necessary for all substitute parts?
A: Yes. All listed substitutes are ROHS3 compliant and REACH unaffected, matching the main part's compliance status.

Q: Can substitute parts be used interchangeably based on product status?
A: Yes. All listed parts are classified as active, enabling direct substitution within supplied product parameters.

Q: Do substitute MOSFETs differ in performance characteristics?
A: Differences in continuous drain current (Id), Rds On, gate charge, and power dissipation are provided for direct engineering comparison. Selection is strictly based on matching core functional parameters and package requirements.
