Part Audit and Datasheet Verification
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 connector part metadata, find or verify the official datasheet, compare the symbol/footprint/pin descriptions against it, then create a concise review report with any mismatches flagged.

The official Amphenol Conan datasheet URL is already present on the library part, so no datasheet-property update was needed. I’m writing the audit notes now.
Worked for 1 min
Completed the part audit and created Part Information Audit — 91921-31111LF.
Summary: the official Amphenol Conan datasheet URL was already set, the symbol has the correct 11 passive contacts, and the footprint includes 11 signal pads plus SH1/SH2 retention pads. I flagged non-blocking metadata issues: connector subtype appears wrong, terminal pin descriptions are missing, terminal prefix metadata is inconsistent, and the +125 °C temperature claim should be verified against Amphenol’s detailed product spec before treating it as authoritative.

Key Datasheet Specs
- Current rating: 1.0 A continuous per contact, all contacts powered.
- Contact resistance: 30 mΩ max.
- Insulation resistance: 1000 MΩ min.
- Withstanding voltage: 500 VAC RMS, 60 Hz.
- Signal integrity: connector-only differential impedance 100 Ω ±10 Ω at 50 ps edge; insertion loss <1.5 dB up to 5 GHz.
- Mating force: 125 g/contact max.
- Unmating force: 25 g/contact min.
- Connector-to-PCB retention force: 44 N min.
- Contact wipe: 0.64 mm.
- Durability: 30 mating cycles.
- Housing material: cream LCP, UL94V-0.
- Contact base metal: high-spring copper alloy for receptacle.
- Environmental note from datasheet: high-temperature life listed at 105 °C; project description states operating range −55 °C to +125 °C, which should be verified against the detailed product specification GS-12-006 or product page before relying on +125 °C as an operating limit.
Schematic Symbol Cross-Check
Observed schematic terminals:
- 11 terminal components are present with Pin Number values 1 through 11.
- Terminal Order values match the same numeric sequence 1 through 11.
- Pin Type is Passive on every contact, which is appropriate for a passive connector.
- The pin placement is split into two sides: pins 1–6 on one side and pins 7–11 on the other, matching an 11-position dual-row connector representation.
Symbol mismatches / concerns:
- Terminal-level pin names appear as
undefinedin the schematic readout. For a connector, this is often acceptable if Pin Number is authoritative, but adding Pin Description values such asContact 1throughContact 11would improve symbol clarity and reviewability. - Terminal components show Designator Prefix
P, while the library part metadata uses Designator PrefixJ. This is not an electrical error for terminal subparts, but it is inconsistent metadata and may confuse reviews if exposed outside the symbol internals. - No functional pin descriptions are present. The datasheet treats the positions as generic connector contacts, so no special signal names are required; however, generic descriptions are recommended.
Footprint / Layout Cross-Check
Observed assets and layout:
- Footprint asset present:
AMPHENOL_91921-31111LF.kicad_mod. - 3D model asset present:
91921-31111LF.STEP. - Symbol asset present and marked default.
- Layout contains 11 signal pads labeled 1–11.
- Layout also contains two mount / solder retention pads labeled SH1 and SH2.
- Silk outline and pin-1 marker are present.
Footprint cross-check result:
- Pad count matches datasheet/product information: 11 electrical contacts.
- Retention/shield pads are present, matching the datasheet feature of metal hold-down / solder retention support.
- SMT footprint style is consistent with the part description.
- Exact pad dimensions could not be fully verified from the OCR extraction of the product drawing because the drawing content was not text-extracted reliably. Visual/layout evidence and imported footprint naming strongly indicate the correct dedicated footprint, but a manual dimensional check against Amphenol drawing 91900 is recommended for release.
Datasheet Property Check
The library part already has the Datasheet URL property set to the official Amphenol Conan datasheet:
No update was required.
Review Tool Result
Part review checks queried for MPN, manufacturer, datasheet, terminal metadata, terminal pin numbers, missing properties, and missing footprint. No review categories or violations were returned at the time of audit.
Flagged Mismatches / Action Items
- Metadata mismatch: Manufacturer in library search appears as
Otherin one field, whileManufacturer Nameis correctly set toAmphenol ICC (FCI). Recommended: normalize manufacturer metadata if the part editor exposes the manufacturer field. - Connector type metadata mismatch: Part-type-specific value is listed as
RF / Coaxial Connectors, but the part is actually a board-to-board mezzanine connector. Recommended: update connector subtype/category to board-to-board/mezzanine if configurable. - Terminal descriptions missing: Add Pin Description values
Contact 1…Contact 11for clarity. - Terminal prefix inconsistency: Terminal subcomponents use prefix
P; library part usesJ. No electrical issue, but prefer consistent connector prefixJfor the assembled part. - Temperature range uncertainty: Project description lists −55 °C to +125 °C, while extracted datasheet text explicitly surfaced high-temperature life at 105 °C. Verify the operating-temperature rating from Amphenol product specification GS-12-006 or official product page before using +125 °C in a formal datasheet field.
- Footprint dimensions: Electrical pad count and shield pads look correct, but exact recommended-land-pattern dimensions should be manually checked against drawing 91900 because automated OCR did not extract the dimensional table reliably.
Overall Assessment
The part is substantially consistent with the official Amphenol Conan 1.00 mm connector family information: 91921-31111LF is an 11-position vertical SMT receptacle with GXT plating, tape-and-reel packaging, and two retention pads. No blocking symbol/footprint mismatch was found. The main issues are metadata quality and incomplete terminal descriptions, not electrical correctness.
