Part Metadata Review and Audit
Thought for 3 mins 40 sec
I reviewed the part metadata, searched for the official datasheet, updated the missing
What I updated
Datasheet URL, and compared the current symbol/footprint against the datasheet-driven expectations described in the part-sync workflow- Set
Datasheet URLto 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
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 |
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 NameandManufacturer Part Numberlook consistent.Datasheet URLwas missing and is now set.Package or Case Codeis still missing. The workflow recommends keeping exact package/case metadata aligned to the datasheet/property schema- No populated description was found.
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 Descriptionproperties 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
This is the biggest issue.
Datasheet footprint expectation:
- 24 signal pads
- 4 shell tabs
- No mounting holes
Current project footprint:
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.
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 |
- 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 Codeand a concise project description using the exact property conventions to avoid duplicate metadata fields
If you want, I can do the next pass and:
Fix pin metadata
Resolve footprint mismatch
Add package metadata
Set Datasheet URL to "https://app.adam-tech.com/pro..."
Set Datasheet URL to "https://app.adam-tech.com/products/download/data_sheet/195307/usb-c31-s-vt-cs4-bk-pp-t-r-data-sheet.pdf"
