Part Information Review and Cross-Check

flux

The part already has an Amphenol datasheet URL set, so I’ll use that as the source of truth and continue with the cross-check.

flux

The datasheet OCR only exposed the product-structure page, so I’m doing a broader official/source search before finalizing the mismatch list.

flux

Completed the part audit. The existing Datasheet URL is already an official Amphenol drawing, so no property update was needed; the symbol has pins 1–100 and the footprint has 100 pads, with no hard pin-count mismatch found.
Open items:
  • Pin descriptions are missing for all contacts.
  • Pin Type is Unspecified for every terminal.
  • Exact footprint pad dimensions could not be fully machine-verified from the available structured output/OCR.
I created the detailed report here: Part Review: Amphenol 10164227-1004A1RLF. Suggested next steps: add standardized contact descriptions, change pin types to Passive if desired, and manually compare land pattern dimensions against the Amphenol drawing/application spec before release.

Schematic symbol cross-check
Observed in Flux:
  • Symbol contains 100 terminal components.
  • Pin numbers/designators cover 1 through 100.
  • Each terminal has Pin Number matching its numeric designator.
  • Pin Type is Unspecified for every terminal.
  • No Pin Description or functional pin name metadata is present.
  • Symbol placement uses two columns: odd-numbered pins on the left and even-numbered pins on the right, matching a common two-row connector presentation.
Assessment:
  • Pin count matches the 100-position datasheet/product description.
  • Numeric pin coverage appears complete: no missing or duplicate pin numbers found from the inspected schematic data.
  • Generic terminal representation is acceptable for a passive mezzanine connector, but pin descriptions are incomplete if the part library standard expects explicit contact descriptions.
Footprint cross-check
Observed in Flux:
  • PCB layout has 100 pad nodes with numeric designators including 1 through 100.
  • Footprint asset/index reference: 101642271004A1RLF.kicad_mod / default footprint.
  • Visible footprint outline is approximately 22.6 mm x 3.0 mm inner outline, with outer silk/assembly outline approximately 24.6 mm x 5.78 mm.
  • Silkscreen/ref/value placeholders are present.
Assessment:
  • Footprint pad count matches the 100-position device.
  • Pad designators align with symbol numbering conceptually.
  • The available tool output did not expose individual pad dimensions, pad pitch, or exact pad coordinates, so the 0.40 mm pitch and recommended land pattern dimensions could not be fully verified numerically against the drawing/application specification.
  • Because the footprint name exactly matches the MPN and pad count is correct, there is no direct evidence of a wrong footprint, but a dimensional CAD check against the Amphenol drawing/application spec is still recommended before release.
Mismatches / issues flagged
  1. Datasheet property points to drawing only
    • The current Datasheet URL is official and valid, but it is a drawing PDF. It does not expose the full electrical specification in OCR/search.
    • Recommended improvement: add product specification GS-12-1404 or family datasheet/eBrochure as an additional Reference Design URL / Product Info URL if available in the property schema, or replace Datasheet URL only if the team expects “Datasheet URL” to mean the broader electrical datasheet rather than the drawing.
  2. Pin descriptions missing
    • All 100 terminals lack meaningful Pin Description values.
    • For this connector, pin descriptions could be standardized as Contact 1 through Contact 100 unless a mating board assignment is known.
  3. Pin type is Unspecified for all pins
    • For a passive connector this may be acceptable, but Passive would be more semantically precise if supported by the library convention.
  4. Footprint dimensions not fully machine-verified
    • The project shows 100 pads and correct footprint identity, but exact land pattern pitch/pad sizes were not available in structured output and the drawing OCR extraction was incomplete.
    • Manual visual/dimensional verification against Amphenol drawing 10164227.pdf and application spec GS-20-0793 is recommended before manufacturing.
Overall conclusion
The part metadata, 100-position symbol, and 100-pad footprint are broadly consistent with Amphenol 10164227-1004A1RLF. No hard pin-count or pin-number mismatch was found. The main gaps are metadata quality: missing pin descriptions, unspecified electrical pin type, and limited footprint dimensional verification due to inaccessible structured pad geometry/drawing OCR.
