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 5 sec

I’ll review the part metadata, find and set the official datasheet URL if missing, then compare symbol/footprint/pin details against the datasheet and report any mismatches.

The part already has a Datasheet URL set, so I won’t overwrite it unless the datasheet check shows it is wrong. I’m extracting the official pin/mechanical data now and comparing it with the existing symbol and footprint.

Reviewed the part against the Würth 68611614422 datasheet and created the full report here: Part Datasheet Review: Würth Elektronik 68611614422.

Key result: the footprint mostly matches the datasheet, but the symbol needs cleanup—missing Part Type, missing pin descriptions, all pin types unspecified, and pads 17/18 should be identified as mounting/hold-down pads. The only geometry item to verify is hold-down pad size: current 1.8 × 2.6 mm vs apparent datasheet 1.7 × 2.6 mm.

Manufacturer Part Number	68611614422	Matches Würth order code 68611614422
Manufacturer Name	Würth	Matches Würth Elektronik eiSos GmbH & Co. KG

Because a Datasheet URL was already set, I did not overwrite it. I used the existing PDF for datasheet extraction and also located the direct official Würth PDF URL above for reference.

Symbol review

Current schematic symbol / terminal model:

18 terminals are present: 1 through 18.
Terminals 1-16 correspond to the 16 FPC signal contacts.
Terminals 17 and 18 correspond to the two SMT hold-down / mechanical solder pads in the footprint.
All terminals currently have Pin Type: Unspecified.
No terminal has a Pin Description.

Findings:

Table

Item	Result
Signal contact count	Matches: datasheet has 16 electrical contacts, symbol includes terminals 1-16
Total footprint pad exposure	Acceptable if intentional: footprint has 16 contacts + 2 hold-down pads, so 18 terminals can be useful if pads 17/18 need PCB connectivity/control
Mechanical pad identification	Mismatch / incomplete: pads 17/18 are not described as mounting pads or solder tabs
Pin descriptions	Missing for all terminals
Pin types	Incomplete: all are unspecified; contact pins are better as Passive, mechanical pads should be marked/described as mechanical/solder tabs if supported

Recommended terminal descriptions:

Table

Terminal range	Suggested description	Suggested type
1-16	Contact 1 ... Contact 16	Passive / connector contact
17-18	Mounting Pad / Solder Tab / Hold-down Pad	Mechanical, no-connect, or passive depending on Flux convention

Footprint review

Current footprint data from embedded KiCad footprint:

Table

Feature	Current footprint	Datasheet comparison
Signal pads	Pads 1-16	Matches 16 contacts
Signal pitch	1.0 mm	Matches datasheet pitch 1.0 mm
Signal center span	17.6 - 2.6 = 15.0 mm	Matches Pl = 15 mm
Signal pad size	0.6 mm x 2.2 mm	Matches likely recommended land pattern values 0.6 and 2.2 mm
Hold-down pads	Pads 17/18	Matches two mechanical SMT pads implied by footprint/connector type
Hold-down pad centers	x=0 and x=20.2 mm	Symmetric around connector center; plausible
Hold-down pad size	1.8 mm x 2.6 mm	Needs verification: datasheet OCR shows 1.7 and 2.6 mm dimensions, suggesting intended width may be 1.7 mm
Fab outline width	-1.4 to 21.6 = 23.0 mm	Matches L = 23 mm
Fab outline height	-1.8 to 3.6 = 5.4 mm	Matches datasheet OCR body height 5.4 mm
Courtyard	-2.4..22.6 by -5.2..4.6 mm	Conservative; no mismatch identified
Pin 1 marker	Silk mark at x=2.6, y=-4.15	Present and aligned near pad 1

Main footprint concern:

The footprint is dimensionally coherent and mostly matches the datasheet.
The only geometry item that should be manually verified against the original land-pattern drawing is the hold-down pad width: current footprint uses 1.8 mm x 2.6 mm, while the datasheet OCR includes 1.7 mm and 2.6 mm in the land pattern. If 1.7 mm is the intended hold-down pad width, the current 1.8 mm is +0.1 mm and outside the stated land-pattern general tolerance of ±0.05 mm.
Because the land-pattern OCR is ambiguous, this is flagged as a verification item rather than a confirmed footprint error.

Review check results

Flux component review currently reports one warning:

Missing Properties: Project Part Type is not set.

Mismatch / cleanup list

Part Type is missing; set to Connector / FFC-FPC ZIF connector.
Pin descriptions are missing for all terminals.
Pins 17 and 18 should be explicitly identified as mounting / solder-tab / hold-down pads.
Pin Type is currently Unspecified for all terminals; consider Passive for contacts 1-16 and a mechanical/no-connect/passive convention for pads 17/18.
Verify hold-down pad size against the original land-pattern drawing: current 1.8 mm x 2.6 mm vs apparent datasheet 1.7 mm x 2.6 mm.
Datasheet property currently points to an uploaded PDF, not the direct official Würth URL. This is not a failure because a datasheet is set, but the official URL is available if you want to normalize the property.

Overall assessment

The part metadata, signal contact count, contact pitch, signal pad spacing, signal pad dimensions, fab outline width, and fab outline height are consistent with the Würth 68611614422 datasheet. The symbol needs metadata cleanup, especially pin descriptions and mechanical pad identification. The only potentially dimensional footprint mismatch is the hold-down pad width, which should be verified visually against the official land-pattern drawing because OCR extraction is ambiguous.
