Part Metadata Review and Audit

Thought for 3 mins 40 sec

I reviewed the part metadata, searched for the official datasheet, updated the missing Datasheet URL, and compared the current symbol/footprint against the datasheet-driven expectations described in the part-sync workflow

What I updated

Set Datasheet URL to the official Adam Tech PDF:
- https://app.adam-tech.com/products/download/data_sheet/195307/usb-c31-s-vt-cs4-bk-pp-t-r-data-sheet.pdf

Current part info found

Table

Field	Current value
Manufacturer Name	Adam Tech
Manufacturer Part Number	USB-C31-S-VT-CS4-BK-PP-T/R
Part Type	Connectors
Designator Prefix	J
Mount	Surface Mount
Footprint asset	USBC31SVTCS4BKPPTR.kicad_mod
Indexed footprint label	USB-C31-S-VT-CS4-BK-PP-T_R
Current terminal/pad count	30
Project description	Not populated

Key specs I could confirm from the datasheet

From the official PDF I was able to extract these reliably:

USB Type-C female/receptacle
Vertical orientation
SMT style
24 signal contacts
0.50 mm contact pitch
4 SMT shell tabs
Shell is tied to GND
Recommended layout shows no mounting holes
Approximate body dimensions called out include about 9.10 mm width and 13.30 mm body depth

I could not reliably extract the electrical ratings text block from the PDF with the available parser, so I’m not going to guess values like current rating or dielectric rating.

Cross-check results 1) Project properties

Manufacturer Name and Manufacturer Part Number look consistent.
Datasheet URL was missing and is now set.
Package or Case Code is still missing. The workflow recommends keeping exact package/case metadata aligned to the datasheet/property schema
No populated description was found.

2) Symbol / pin audit

Good:

The symbol includes the expected USB-C signal pins A1-A12 and B1-B12.
Shell pins are represented separately, which is directionally correct because the datasheet calls out shell tied to ground.

Problems:

All terminals currently have Pin Type = Unspecified. That is a mismatch versus a datasheet-synced part, where pin types should be classified exactly from the datasheet rather than left generic
I did not find Pin Description properties on the terminals. The sync workflow expects short per-pin descriptions when available
Because of that, key pin intent is not encoded today:
- CC pins are not identified as configuration pins
- D+/D- pins are not described
- SuperSpeed TX/RX pins are not described
- VBUS / GND / shield roles are not formally typed

3) Footprint audit

This is the biggest issue.

Datasheet footprint expectation:

24 signal pads
4 shell tabs
No mounting holes

Current project footprint:

30 terminals / 30 pads
Includes two extra mounting-hole style terminals: MH_1 and MH_2

Mismatch flagged

Pad-count mismatch: datasheet indicates 28 total electrical/mechanical pads, project has 30.
The extra count appears to come from MH_1 and MH_2.
That strongly suggests either:
- the footprint imported two non-datasheet mounting features, or
- two shell/mechanical features were split/labeled differently than the datasheet intends.

Summary of mismatches

Table

Area	Status	Notes
MPN	OK	Matches project metadata
Manufacturer	OK	Matches project metadata
Datasheet URL	Fixed	Official PDF added
Symbol pin names	Mostly OK	A/B pin naming looks consistent
Pin count	Mismatch	Project has 30, datasheet footprint implies 28
Shell handling	Partial	Shell exists, but extra MH terminals are suspicious
Pin types	Mismatch	All terminals are `Unspecified`
Pin descriptions	Missing	No short functional descriptions found
Footprint style	Likely OK	Vertical SMT Type-C is consistent
Footprint exact geometry	Partially checked	Count/style aligns except for extra MH pads

Recommended next actions

Remove or reclassify the two extra mounting-hole terminals if they are not actually present in the datasheet footprint.
Set proper pin types and short pin descriptions for all terminals, per the datasheet-sync workflow
Add Package or Case Code and a concise project description using the exact property conventions to avoid duplicate metadata fields

If you want, I can do the next pass and:

classify all pin types,
add pin descriptions,
and resolve the MH_1 / MH_2 footprint mismatch.
