Equivalent & Substitute Parts Reference for APT6038BLLG

Part Overview

The APT6038BLLG by Microchip Technology is an N-channel MOSFET rated at 600 V and 17A (Tc), offered in a TO-247-3 package with through-hole mounting. This part is currently active and in-stock. It serves power switching and conversion systems requiring high voltage and substantial current handling. When the primary part is unavailable due to manufacturer lead time, allocation, or lifecycle status, identifying substitute MOSFETs with matching electrical and mechanical parameters is necessary for uninterrupted application performance.

APT6038BLLG	Transistors, FETs, MOSFETs	600 V	17A (Tc)	380mOhm @ 8.5A, 10V	5V @ 1mA	43 nC @ 10 V	1850 pF @ 25 V	N-Channel	MOSFET (Metal Oxide)	Through Hole	TO-247-3	ROHS3 Compliant	Active

Substitute Part Grouping Explanation

Substitute selection is strictly governed by matching electrical and mechanical parameters: Drain to Source Voltage (Vdss), Continuous Drain Current (Id), Rds On at rated conditions, threshold voltage (Vgs(th)), Gate Charge (Qg), Input Capacitance (Ciss), FET type, technology, mounting, and package/case. Only N-channel, through-hole MOSFETs in the TO-247-3 or directly compatible packages, within the same or greater Vdss, Id, and comparable Rds On, can be considered substitutes when product status and compliance also align.

Engineering Selection Recommendations

When selecting substitute parts for APT6038BLLG, confirm product status as "Active" to ensure continuous supply. All substitute parts listed are ROHS3 compliant and have unlimited moisture sensitivity levels (MSL 1), meeting standard regulatory and environmental criteria for global designs. REACH status is unaffected for each part. Package and case types are strictly TO-247-3 or compatible variants, supporting direct mechanical interchange and through-hole mounting. Obsolete status, as with AOK20N60L, limits its appropriateness where supply continuity is essential.

Frequently Asked Questions (FAQ)

Q: What are the main criteria for selecting a substitute for APT6038BLLG?
A: Substitute selection is based on matching drain to source voltage (Vdss), continuous drain current (Id), Rds On at the specified conditions, gate threshold voltage (Vgs(th)), gate charge (Qg), input capacitance (Ciss), FET type, technology, mounting type, package/case, and compliance statuses.

Q: Is package compatibility required for substitution?
A: Yes, only TO-247-3 packages or specified variants with through-hole mounting are considered compatible substitutes, ensuring mechanical interchangeability.

Q: Does ROHS3 compliance affect substitution eligibility?
A: All substitute parts must be ROHS3 compliant for global regulatory acceptance.

Q: Can substitute parts be selected if they are obsolete?
A: Obsolete parts such as AOK20N60L are included for reference, but active parts are recommended for uninterrupted manufacturing and repair processes.

Q: How should variations in gate charge and capacitance be addressed?
A: Variations in gate charge (Qg) and input capacitance (Ciss) are compared directly; only provided parameter values are considered acceptable for substitution.

Q: Is manufacturer or series relevant in substitution?
A: Substitution is based solely on provided electrical, mechanical, and compliance parameters; manufacturer or series is specified for traceability but does not determine compatibility in this context.
