Part Information Review

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 a moment

Reviewed the part and confirmed/updated the official Amphenol Datasheet URL. The schematic symbol matches the 22-position, 2-row pin count/numbering, but I flagged footprint risks: pad diameter appears smaller than the official Ø1.78 mm recommendation, and the through-hole drill/pad type should be verified against the Ø1.02 mm drilled-hole drawing. Full analysis is in the Part Information Review — 77313-118-22LF project file.

Part Information Review — 77313-118-22LF

Scope

Reviewed available project metadata, schematic terminal symbol, footprint/pad layout, 3D/footprint assets, official Amphenol documentation, and the datasheet/drawing for Amphenol ICC / FCI 77313-118-22LF.

This review follows the part-project datasheet-sync rule that the datasheet/drawing is the single source of truth for exact pin count, pin numbering, and footprint-critical dimensions; exact pin numbers must not be guessed and the project pin count must match the datasheet count.

Datasheet URL status

A Datasheet URL was already present in the project context:

https://cdn.amphenol-cs.com/media/wysiwyg/files/documentation/datasheet/boardwiretoboard/bwb_bergstik.pdf

I verified this is an official Amphenol BergStik datasheet/eBrochure and set/confirmed it on the project properties. I also used the official Amphenol drawing:

Schematic symbol cross-check

What matches

The schematic has 22 terminal components, matching the datasheet/drawing position count.
Terminal pin numbers are present as 01 through 22, matching the required count and numbering format.
Symbol arrangement is logical for a 2-row header: odd pins on one side and even pins on the other side, corresponding to the drawing pin arrangement:
- Row 1: 1 3 5 7 9 11 13 15 17 19 21
- Row 2: 2 4 6 8 10 12 14 16 18 20 22
Pin Type = Passive for all terminals is appropriate for simple connector contacts.

Issues / gaps

The terminal labels are numeric only (01…22). That is acceptable for a pin header, but there are no Pin Description properties such as “Contact 1”, “Contact 2”, etc.
No terminal Section, Pin Group, or Pin Orientation properties are set. For a simple connector this is not as critical as for IC-style parts, but adding a short Pin Description would improve library usability.

Footprint cross-check

What matches

The footprint has 22 pads, matching the part’s 22 positions.
Pad numbering matches the drawing pattern: odd pins are one row, even pins are the other row.
Pad pitch is consistent with the drawing:
- Along-row pitch: 2.54 mm
- Row spacing: 2.54 mm
Pin 1 is rectangular, which is a common and useful orientation marker.
Footprint assets exist:
- KiCad footprint asset: AMPHENOL_77313-118-22LF.kicad_mod
- STEP 3D model asset: 77313-118-22LF.step
- Symbol SVG asset is set as default thumbnail/symbol.

Issues / mismatches

Pad diameter appears undersized
- Drawing recommendation: Ø1.78 mm pad.
- Layout pad size: 1.65 mm.
- Difference: pad is about 0.13 mm smaller than the drawing recommendation.
Drill/hole size appears incorrect or not explicitly defined
- Drawing recommendation: Ø1.02 ± 0.08 mm drilled hole.
- Layout output does not show a per-pad hole size; system default pad hole size is 0.7 mm.
- If the footprint is actually inheriting 0.7 mm, this is too small for the specified 0.64 mm square posts and official 1.02 mm drill recommendation.
Pad type ambiguity
- The component is a through-hole connector.
- Layout output shows pads with forceAnnularLayers: Top, Bottom, but the system default pad type is SMD unless overridden. The tool output did not explicitly show padHoleType: throughHole on the pads.
- This should be verified/fixed so each pad is explicitly through-hole with the proper drill.

Project metadata review

Matches / acceptable

Designator Prefix: J — correct for connector.
Manufacturer Part Number: 77313-118-22LF — correct.
Manufacturer Name: Amphenol Communications Solutions / Amphenol ICC — correct.
Part Type: Connector — correct.
Connector Pitch: 2.54 mm — correct.
Connector Positions: 22 — correct.
Connector Rows: 2 — correct.
Current Rating: 3 A — mostly correct, but see fully-energized note.
Package or Case Code: “2.54 mm double-row vertical through-hole header, 22 positions” — descriptive and consistent.

Potential property mismatch

Operating Temperature: project has -65°C to +130°C; extracted BergStik brochure states -65°C to +125°C. The official product page search result reported -65°C to +130°C. Because Amphenol documentation sources differ, this should be resolved using the exact product page or product specification for this MPN before changing the property.

Recommended fixes

Fix footprint pad geometry
- Set through-hole drill to Ø1.02 mm.
- Set pad diameter to Ø1.78 mm.
- Ensure all pads are explicitly through-hole / plated through-hole.
Add concise pin descriptions
- For terminals 01–22: add Pin Description = Contact 1 … Contact 22.
Add implementation details
- Add the current-rating nuance: “3 A continuous; 2 A DC max per contact for fully energized connector.”
- Add dielectric/insulation specs if useful for library search/review.
Resolve operating temperature discrepancy
- Confirm whether the official MPN-specific product page or product specification should be treated as authoritative over the family brochure.

Overall verdict

The part is mostly correct at the schematic/metadata level: it has the right MPN, manufacturer, connector category, 22 terminals, 2-row numbering, and 2.54 mm spacing. The main risk is the footprint pad/drill definition, which appears smaller than the official drawing recommendation and may not explicitly be through-hole. Fixing that should be the top priority before publishing or using this part in a board design.
