Equivalent & Substitute Parts Reference: APT5010LLLG

Part Overview

APT5010LLLG is an N-Channel MOSFET from Microchip Technology, classified under the Transistors, FETs, MOSFETs category. It features a drain-source voltage rating of 500V, a continuous drain current of 46A (Tc), and a maximum power dissipation of 520W (Tc). The device is housed in a TO-264 [L] package for through-hole mounting. With active product status and RoHS3 compliance, APT5010LLLG is suitable for high-power switching applications. Identification of equivalent and substitute models is required for sourcing flexibility, production continuity, and inventory management within the permitted electrical, mechanical, and compliance parameters.

Substitute Part Grouping Explanation

Substitution is determined strictly by comparing the electrical and mechanical parameters: drain-source voltage, continuous drain current, maximum Rds On, gate threshold voltage, gate charge, gate-source voltage rating, input capacitance, power dissipation, operating temperature range, mounting style, package type, and RoHS status. Only parts matching or closely aligning in these fields are included as substitutes.

Engineering Selection Recommendations

All listed substitute parts (APT5010LFLLG, IXFK44N50P) and the main part (APT5010LLLG) are currently active and ROHS3 compliant. Each part is supplied in through-hole TO-264 case variants and features an unlimited moisture sensitivity level. Inventory for each part is shown as new original in stock; compliance and product status parameters support direct substitution for applications requiring these certifications.

Frequently Asked Questions (FAQ)

Q1: Which key parameters must match when substituting MOSFETs in the TO-264 package category?
A1: The core substitution parameters are drain-source voltage rating, continuous drain current, maximum Rds On, gate threshold voltage, gate charge, gate-source voltage rating, input capacitance, power dissipation, operating temperature range, mounting style, and package/case type. Compliance certifications are also required.

Q2: Can APT5010LFLLG be directly substituted for APT5010LLLG in power applications?
A2: Yes; based strictly on the provided parameters, APT5010LFLLG matches all necessary electrical, mechanical, and compliance criteria.

Q3: Is IXFK44N50P suitable as a substitute for APT5010LLLG?
A3: IXFK44N50P can be substituted, with similar key parameters such as drain-source voltage, gate-source voltage, mounting type, and compliance status. Differences such as continuous drain current and Rds On should be evaluated for application-specific requirements.

Q4: What mechanical considerations are important when substituting between TO-264 package MOSFETs?
A4: Package type, mounting style (through-hole), and dimensional equivalence are mandatory; only the TO-264-3 and TO-264AA cases as listed are considered in these substitutions.

Q5: Are there compliance or certification concerns when changing between these parts?
A5: All referenced parts are ROHS3 compliant, have unlimited moisture sensitivity levels, and are REACH unaffected based on the provided input parameters. No additional certifications are present in the provided data.
