Engineering Selection Recommendations

The SKI07171 is obsolete. Substitute parts BUK7613-60E,118; HUF76439S3ST; and PSMN015-60BS,118 are classified as active and comply with ROHS3 requirements. All substitutes provided are surface mount MOSFETs in TO-263/D2PAK packaging, with a Moisture Sensitivity Level of 1 (Unlimited). These alternatives ensure continuity of supply and compliance with current environmental standards within the specified product category.

Frequently Asked Questions (FAQ)

Q1: What are the critical electrical parameters to match when selecting a substitute for SKI07171?
A1: Substitute selection is determined by FET type, technology, drain-to-source voltage (Vdss), continuous drain current (Id), Rds On, gate voltage ratings, and package compatibility.

Q2: Why must the package type match for MOSFET substitution?
A2: Matching the package (TO-263-3, D2PAK, TO-263AB) maintains mechanical fit and thermal management in the PCB layout without requiring redesign.

Q3: Are all suggested substitute MOSFETs RoHS compliant?
A3: Yes, the listed substitute MOSFETs are ROHS3 compliant and have a Moisture Sensitivity Level of 1 (Unlimited).

Q4: Can the substitutes operate within the same environmental conditions?
A4: Substitute parts meet or exceed the specified operating temperature ranges and power dissipation, ensuring compatibility for similar application environments.
