APT58M80J Equivalent & Substitute Parts Reference

Part Overview

The APT58M80J (Microchip Technology) is an N-Channel MOSFET designed for high-power switching applications. It features an 800 V drain-to-source voltage, 60A continuous drain current, and a maximum power dissipation of 960W, provided in a SOT-227 chassis mount package. The product is currently active and compliant with ROHS3 and REACH standards. Identifying direct alternatives for APT58M80J may be necessary for reasons such as multi-source qualification, risk mitigation against supply disruptions, or existing inventory exhaustion.

Substitute Part Grouping Explanation

Component substitution for the APT58M80J is strictly determined by the following parameters:
Drain-to-source voltage (Vdss), continuous drain current (Id) at 25°C, Rds(on) (max), gate threshold voltage (Vgs(th)), maximum gate charge (Qg), input capacitance (Ciss), maximum power dissipation, maximum Vgs, operating temperature range, mounting type, package/case style, RoHS and REACH compliance, and product status. Only parts matching or closely approximating the provided values for these characteristics and maintaining the same mechanical footprint are considered substitutes in the Transistors, FETs, MOSFETs category.

Engineering Selection Recommendations

All compared MOSFET part numbers share an active lifecycle status. Each substitute, IXFN62N80Q3 and IXFN48N60P, is ROHS3 compliant, REACH unaffected, and classified as MSL 1 (unlimited shelf life). All are packaged in the SOT-227-4, miniBLOC form and support chassis mounting.
Selection must be based on required regulatory certifications, compliance standards, and product status, using only the explicitly listed technical and regulatory parameters.

Frequently Asked Questions (FAQ)

Q1: What determines if a MOSFET can be substituted in this category?
Strict substitution criteria include drain-source voltage, continuous drain current, Rds(on), gate threshold voltage, gate charge, power dissipation, mechanical form factor, regulatory compliance, and product status.

Q2: Are all substitutes compatible with the same PCB footprint and mechanical mounting?
All listed alternatives (APT58M80J, IXFN62N80Q3, IXFN48N60P) use the SOT-227-4, miniBLOC chassis mount package.

Q3: Do the substitutes provide the same maximum electrical and thermal parameters?
Values for Vdss, Id, Rds(on), and power dissipation differ between parts. Selection must align with the required parameter limits for the intended application.

Q4: Are there differences in RoHS, REACH, or MSL status?
All parts are ROHS3 compliant, REACH unaffected, and have a moisture sensitivity level of 1 (unlimited).

Q5: Is the operating temperature range consistent across all listed parts?
All compared parts specify an operating junction temperature of -55°C to 150°C.
