Part Datasheet 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.

flux

I’ll review the part metadata, find and set the official datasheet URL if it’s missing, then compare the symbol/footprint/pin data against the datasheet and report any mismatches.

flux

The part already has an Amphenol datasheet URL set, so I’m using that as the source of truth and checking the connector metadata, pins, and footprint against it.

Completed the part review and created Part Datasheet Review — AC3FAH1-AU-PRE. The datasheet URL was already set, the MPN/manufacturer/pin count and footprint match the Amphenol drawing, and the main issues are incomplete pin descriptions/types, ambiguous pin-1 labeling (1+G vs G), and incomplete structured connector metadata.
Suggested next steps:
  • Update pin descriptions and set connector pins to Passive.
  • Relabel or describe pin 1 as 1+G / chassis / shell ground.
  • Add structured connector properties: XLR, female, 3 positions, horizontal PCB/through-hole, 133 V, 6 A, -25 °C to +75 °C.

Datasheet contactDatasheet pin descriptionFlux symbol observationResult
PIN 11+G; mating shell and chassis connected to 1+GTerminal designator G, Pin Number 1, Pin Type Unspecified, no pin descriptionNumbering matches; label/description is incomplete
PIN 22Terminal designator 2, Pin Number 2, Pin Type Unspecified, no pin descriptionNumbering matches; metadata incomplete
PIN 33Terminal designator 3, Pin Number 3, Pin Type Unspecified, no pin descriptionNumbering matches; metadata incomplete
Symbol findings
  • Electrical pin count is correct: 3 schematic terminals for the 3 connector contacts.
  • Pin numbering matches the datasheet.
  • Pin 1 should ideally be shown/described as 1+G rather than only G, because the datasheet explicitly ties mating shell and chassis to 1+G.
  • Pin descriptions are missing; all three pins are currently Unspecified type. For a passive connector, Passive is a better pin type for pins 1, 2, and 3.
  • Component review checks report missing parametric symbol properties: Pin Group, Pin Orientation, and Section for G, 2, 3, and also mechanical layout pads/holes 4, 5.

Footprint findings
  • The footprint’s electrical pad coordinates, pad sizes, drill sizes, and two NPTH mounting holes appear to match the datasheet nominal PCB layout.
  • The datasheet states PCB layout tolerance ±0.05 mm; critical production use should still be checked visually against the original drawing PDF because the automated datasheet extraction is OCR-based.
  • No footprint mismatch was found from the available structured layout data and extracted datasheet values.
Mismatches / Issues Flagged
  1. Pin metadata incomplete: pins lack datasheet-backed descriptions and use Unspecified pin type.
  2. Pin 1 label incomplete: datasheet says 1+G; symbol currently shows G with Pin Number 1. This is not a numbering error, but it loses the shell/chassis-ground meaning.
  3. Structured connector properties incomplete: useful properties such as Connector Type = XLR/panel mount, Connector Gender = Female, Connector Positions = 3, termination = horizontal PCB/through-hole, voltage/current/test-voltage/temperature ratings are not fully represented as structured properties.
  4. Description wording ambiguous: existing description includes Plug, Female Sockets; datasheet language is better represented as 3-pole XLR female chassis/panel-mount horizontal PCB connector.
  5. Parametric symbol properties missing: review checks report missing Pin Group, Pin Orientation, and Section for electrical pins and mechanical holes.
Overall Verdict
  • Datasheet URL: already present and official; no update required.
  • MPN/manufacturer/pin count: match the datasheet.
  • Footprint: matches the nominal PCB layout dimensions and drill sizes from the datasheet/customer drawing.
  • Primary cleanup needed: enrich pin descriptions/types and connector metadata; optionally relabel pin 1 as 1+G or add the full Pin 1 / Ground / Chassis / Shell description.
