Part Datasheet Review
Worked for 1 min 11 sec
The part already has an Amphenol datasheet URL set, so I’m using that as the source of truth and moving into the symbol/footprint cross-check.

Part Datasheet Review: 10163479-14340T1LF
Date: 2026-07-13 Flux project/part: 10163479-14340T1LF
Review complete. The official Amphenol datasheet URL was already set, so no property update was needed; identity, 400 contacts, row naming, and main contact pad geometry match the datasheet.
I flagged likely issues with the mounting/NPTH hole placement and missing/unspecified pin descriptions/types, and filed an internal part-quality report. Full details are in Part Datasheet Review: 10163479-14340T1LF.
Suggested next steps:
- Visually confirm the NPTH coordinates from the Amphenol PDF.
- Correct the mounting-hole footprint if confirmed.
- Populate terminal pin descriptions and set connector-appropriate pin types.

Schematic Symbol Cross-Check
Matches
- The schematic contains 400 terminal components.
- Terminal naming covers A1-A100, B1-B100, C1-C100, and D1-D100, matching the four-row 400-position datasheet scheme.
- Pin Number properties match the terminal designators.
- No schematic nets are present, which is normal for a connector part project.
Mismatches / Quality Issues
- Datasheet labels show examples as A01, A100, D01, D100. Flux uses A1/D1 without leading zero. This is not electrically wrong, but exact datasheet label formatting is not preserved for 1-9.
- Pin Description is absent on the terminals. For connector usability, each terminal should ideally have a description equal to the positional name, e.g.
A1orA01. - Pin Type is
Unspecifiedon inspected terminals. Connector contacts should ideally use a connector-appropriate passive/bidirectional type for clearer ERC behavior.
Footprint Cross-Check
Contact Pad Array
The 400 contact pads appear consistent with the datasheet when interpreting the layout tool's small numeric values as internal meter-style values equivalent to physical millimeters:
Table
| Feature | Flux footprint | Datasheet | Verdict |
|---|---|---|---|
| Contact pads | 400 | 400 | Match |
| Contact pitch | 0.635 mm inferred | 0.635 mm typ | Match |
| Contact span | ~62.864-62.865 mm | 62.865 mm | Match |
| Row Y positions | +3.4, +1.2, -1.2, -3.4 mm | 6.80 mm span; 2.20/2.40/2.20 spacing | Match |
| Contact pad diameter | 0.356 mm circular | Ø0.356 ±0.050 mm | Match |
Mounting / NPTH Pads
The footprint has two additional circular pads, matching the expected count for two mounting/locating holes, and the diameter matches Ø0.975 mm. Positioning is not fully aligned with the datasheet extraction:
Table
| Feature | Flux footprint | Datasheet extraction | Verdict |
|---|---|---|---|
| Mount hole count | 2 | 2 | Match |
| Mount hole diameter | 0.975 mm | Ø0.975 ±0.050 mm | Match |
| Mount hole X spacing | Appears ±33.56 mm, total 67.12 mm | Extraction indicates 68.62 mm reference / possible center spacing | Needs visual confirmation; likely mismatch if 68.62 mm is hole center spacing |
| Mount hole Y | One at -1.30 mm, one at 0.00 mm | Extraction indicates 1.30 mm vertical coordinate from centerline | Likely mismatch; Y=0 hole is suspicious |
The strongest flagged issue is the mounting/NPTH placement, especially one mounting hole at Y=0.00 mm. Because the drawing OCR is ambiguous about whether 68.62 mm is outline length or mount-hole center spacing, the X-coordinate should be visually confirmed from the PDF before correction.
Overall Verdict
- Identity, datasheet URL, 400-position schematic count, and contact pad field geometry are consistent with the official Amphenol drawing.
- The part should not be considered fully verified until the two mounting/NPTH hole coordinates are visually confirmed and corrected if needed.
- Schematic terminal descriptions and pin types should be improved for usability, though they do not invalidate the contact geometry.
Recommended Fixes
- Visually verify the two mounting/NPTH center coordinates from the Amphenol PDF drawing.
- Correct the mounting/NPTH pad Y coordinate if the second hole should also be offset by 1.30 mm from the centerline.
- Confirm whether mount-hole X centers should be ±34.31 mm or ±33.56 mm.
- Add terminal pin descriptions matching positional names.
- Change terminal Pin Type from
Unspecifiedto a connector-appropriate passive/bidirectional type if supported by the library workflow.
An internal part-quality report was filed for the likely mounting-hole placement issue.
