Part Information Audit and Datasheet Update

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.

Confirmed MPN: Molex 5055670371 / 505567-0371
Part: Micro-Lock PLUS right-angle SMT PCB header, 1.25 mm pitch, single row, 3 circuits, black
Ratings: 1.5 A/contact, 50 V AC RMS/DC, -40°C to +105°C
Footprint matches datasheet: 5 pads total = 3 signal pads + 2 retention nail pads; signal pads are 0.8 × 1.2 mm, nail pads are 1.3 × 2.15 mm, 1.25 mm pitch.
Symbol terminals match expected circuits: 1, 2, 3, SHIELD1, SHIELD2.

I also added datasheet-derived pin descriptions to the terminals. No footprint pad-count or pad-size mismatch found. Minor note: the schematic terminals’ internal pin display shows as undefined, but their Pin Number properties are correct and aligned to the footprint pads.
