Engineering Selection Recommendations

The PMF63UN,115 is marked Obsolete, making continued sourcing unfeasible for production or maintenance. Substitute selection is governed by compliance standards such as RoHS3 and REACH, as well as an unlimited MSL rating, which are both documented as matched for the DMN3067LW-7. Product availability and active status of recommended substitutes are also confirmed, strictly based on provided information.

Frequently Asked Questions (FAQ)

Q1: What are the key criteria for substituting the PMF63UN,115 MOSFET?
A1: Substitution is determined by FET type, maximum drain-source voltage, continuous drain current, drive voltage, Rds(on), gate threshold voltage, gate charge, input capacitance, power dissipation, operating temperature range, package, and compliance status.

Q2: Is the SOT-323 package compatible with SC-70?
A2: Both the PMF63UN,115 and the DMN3067LW-7 are specified as SC-70, SOT-323, confirming package compatibility for surface-mount layouts.

Q3: Is RoHS and REACH compliance assured for the substitute DMN3067LW-7?
A3: Both PMF63UN,115 and DMN3067LW-7 are documented as ROHS3 compliant and REACH unaffected.

Q4: Do power dissipation and operating temperature differ between the original and substitute devices?
A4: Both models support -55°C to +150°C junction temperature range. The DMN3067LW-7 specifies a higher maximum power dissipation at Ta, according to the provided parameters.

Q5: Are the substitute and original parts electrically and mechanically interchangeable based solely on provided specifications?
A5: The provided parameters confirm matching electrical and mechanical characteristics required for substitution, with no reliance on parameters outside the supplied data.
