Part Audit Mismatch Review

A

adrian95

Review all available part information (MPN, package, pin count, description, properties). If no datasheet URL is already set, search the web for the official datasheet and update the part's Datasheet property with the URL. Then cross-check the schematic symbol, footprint, and pin descriptions against the datasheet. Summarize key specs and flag any mismatches.

I’ll audit the part metadata, locate the official datasheet if needed, then compare the symbol, footprint, and pin definitions against it.

Audit complete for NCV4274CST50T3G.
  • Correct: MPN, onsemi manufacturer, four-pin count, and symbol pin mapping: 1 Input, 2/4 Ground, 3 Output.
  • Key specs: 5.0 V ±2%, 400 mA, 5.5–40 V operating input, 0.5 V maximum dropout at 250 mA, −40°C to +150°C, +60 V transient and −42 V reverse protection, AEC-Q100.
  • Datasheet: Already populated with the current onsemi NCV4274C Rev. 5 datasheet; no URL update was necessary.
  • Mismatches: Package should be SOT-223 / Case 318E and mount should be SMD, not “Reverse.” Part Type is missing. Pin types and descriptions are unspecified.
  • Critical footprint issue: All four pads overlap at the origin and are only 0.0016 mm diameter, with no valid SOT-223 geometry. The footprint is not manufacturable.
I filed an internal part-quality report for the footprint and metadata defects.
