Part 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.
Thought for 11 sec
I’ll audit the part metadata, schematic symbol/pins, and footprint against the official datasheet; if the datasheet property is missing, I’ll find the official URL and update it, then save the detailed findings in a project file.
Worked for 12 mins 24 sec
Completed the part audit for 91911-31311LF. I updated the missing Datasheet URL to the official Amphenol CS PDF, populated missing Manufacturer Name and Part Type metadata, cross-checked the 11-pin passive symbol and footprint geometry, and saved the detailed findings in Part Audit: 91911-31311LF.
Key result: the 11 signal pins and 1.00 mm two-row SMT footprint match the available part data; the only caveat is that SH1/SH2 hold-down pads are footprint-only, which is acceptable unless you want them electrically tied to ground/chassis. The final review is clean with no open errors or warnings.

Part Audit: 91911-31311LF
Scope
Reviewed available part information, datasheet availability, schematic symbol terminals, footprint pads, and pin descriptions for Amphenol CS / FCI 91911-31311LF.
Datasheet / Source URLs
- Official manufacturer product page: https://www.amphenol-cs.com/product/9191131311lf.html
- Official manufacturer PDF drawing/datasheet found on Amphenol CS CDN: https://cdn.amphenol-cs.com/media/wysiwyg/files/drawing/91900.pdf
- Distributor cross-check source: Mouser 91911-31311LF product page
- Distributor cross-check source: Newark 91911-31311LF product page
The project had no Datasheet URL set. I updated the project Datasheet URL to the official Amphenol CS CDN PDF above.

Schematic Symbol Check
- The symbol contains 11 terminal components with Pin Numbers 1 through 11.
- Each terminal is configured as passive, which is appropriate for a connector contact with no intrinsic electrical direction.
- No functional pin names were found in the symbol; this is acceptable for this connector because contacts are generic and user-assigned.
- Symbol pin count matches the 11-position connector specification.
Footprint Check
Imported footprint asset:
AMPHENOL_91911-31311LF.kicad_mod.Signal pads:
- 11 SMT rectangular contact pads: pads 1 through 11.
- Pad size: 0.61 mm x 2.41 mm.
- Two signal rows at +/-1.72 mm from footprint center.
- Row A pads: 1, 2, 3, 4, 5, 6 at x = -2.5, -1.5, -0.5, 0.5, 1.5, 2.5 mm.
- Row B pads: 7, 8, 9, 10, 11 at x = -2.0, -1.0, 0.0, 1.0, 2.0 mm.
- This matches an 11-contact, two-row, 1.00 mm pitch staggered contact pattern.
Mechanical / retention features:
- Two custom SMT hold-down / shield pads SH1 and SH2 at x = +/-4.22 mm.
- Two non-plated guide holes at x = +/-3.0225 mm, y = 1.1 mm with 0.84 mm drill/diameter.
- Courtyard is approximately 10.8 mm x 6.35 mm.
- Fab outline is approximately 10.3 mm x 5.0 mm.
Cross-Check Results
Table
| Item | Result |
|---|---|
| MPN | Matches project and official/distributor sources. |
| Position count | Matches: 11 symbol terminals and 11 SMT signal pads. |
| Connector type | Matches: vertical SMT mezzanine/header. |
| Pitch | Footprint signal pad x-spacing is 1.00 mm within each row, matching datasheet/distributor spec. |
| Pin descriptions | Passive/generic terminal descriptions are appropriate; no signal-specific pin functions are expected. |
| Mechanical retention | Footprint includes SH1/SH2 and two guide holes; symbol exposes only 11 electrical contacts, which is acceptable if hold-down tabs are mechanical-only. |
| Datasheet URL | Was missing; now set to the official Amphenol CS PDF. |
Mismatches / Issues Flagged
- The project originally had no Datasheet URL; this was corrected.
- Manufacturer Name and Part Type were missing in the project review; I populated them based on the audit sources.
- The footprint includes two SMT hold-down pads (SH1/SH2) and two guide holes that are not represented as schematic terminals. This is not necessarily an error for mechanical retention pads, but if the design intent requires these tabs to be tied to chassis/ground, the symbol should expose them as pins.
- The official Amphenol PDF was available but OCR extraction was sparse in the automated checker, so detailed parametric values were cross-checked against distributor data and the imported KiCad footprint geometry.
Recommendation
Keep the 11-pin passive symbol as-is for normal connector use. If SH1/SH2 need an electrical connection in the final product, add/represent those hold-down pads as schematic terminals so they can be intentionally connected or marked no-connect.
