Part Information Review and Update
Thought for 2 mins 56 sec
I reviewed the current part metadata and compared the symbol/footprint data against the official GCT documentation. The recommended official datasheet URL to store in the project is https://gct.co/download?type=PDFSpecification&name=usb4235-spec.pdf. The sync workflow here is: verify the existing
Summary
Datasheet URL, use the official datasheet as the source of truth, then compare project properties, terminal count, pin numbers, pin types, descriptions, and footprint coverage against the datasheetTable
| Area | Status | Notes |
|---|---|---|
| Datasheet URL | Missing | No populated Datasheet URL property is present |
| MPN | Mismatch | Project has USB4235-03-C_REVA; official part is USB4235-03-C |
| Manufacturer Name | Missing | Should be GCT (Global Connector Technology) |
| Part Type | Needs cleanup | Connectors is broad; Connector / USB Type-C connector would be better |
| Package / footprint metadata | Missing | No explicit package/case property found |
| Description | Missing / placeholder | Current description is not meaningful |
| Pin/contact coverage | Mostly good | 16 signal/power contacts are present; 2 shield tabs also present |
| Pin descriptions | Missing | No Pin Description property found on any terminal |
| Pin types | Partially wrong | Ground pins are typed as Power In, not Ground |
| Footprint presence | Good | Footprint and STEP model exist and match the USB4235 family |
Table
| Spec | Value |
|---|---|
| Manufacturer | GCT (Global Connector Technology) |
| Official MPN | USB4235-03-C |
| Description | USB Type-C USB 2.0 vertical receptacle |
| Contacts | 16 |
| Mounting | Surface Mount, vertical, top entry, top mount |
| Shell stake | Through Hole, 0.95 mm |
| Voltage rating | 48 V DC |
| Current rating | 5 A |
| Operating temperature | -25°C to +85°C |
| Profile | 6.50 mm |
The project contains the expected USB-C USB 2.0 contacts:
- VBUS: VBUS_A, VBUS_A__1, VBUS_B, VBUS_B__1
- CC: CC1, CC2
- USB2 D+/D-: DP1, DP2, DN1, DN2
- SBU: SBU1, SBU2
- Ground: GND_A, GND_A__1, GND_B, GND_B__1
- Shield tabs: SHIELD, SHIELD__1
The datasheet pin table for the 16 electrical contacts is:
- A1/A12/B1/B12 = GND
- A4/A9/B4/B9 = VBUS
- A5 = CC1, B5 = CC2
- A6/B6 = D+
- A7/B7 = D-
- A8 = SBU1, B8 = SBU2
That matches the project’s pin numbers and names well overall. For part-project verification, the datasheet should remain the single source of truth and pin count should match exactly, including any shield/exposed/mechanical contacts that are intentionally represented as terminals
Mismatches and issues found
Table
| Item | Finding |
|---|---|
| Ground pin type | GND_A, GND_A__1, GND_B, GND_B__1 are set to Power In; they should be Ground |
| Pin descriptions | No Pin Description property exists on any terminal |
| MPN | USB4235-03-C_REVA does not match the official orderable MPN USB4235-03-C |
| Manufacturer property | Missing |
| Datasheet URL property | Missing |
| Description field | Not meaningful |
| Package/case property | Missing explicit package/footprint descriptor |
| Designator prefix consistency | Project uses J, terminals use internal P; this is acceptable internally, but worth keeping in mind |
The layout contains:
- a footprint asset named GCT_USB4235-03-C_REVA.kicad_mod
- a 3D model USB4235-03-C_revA.STEP
- pads for all named electrical pins plus shield pads
This strongly suggests the footprint is intended for the correct family and is directionally consistent with the datasheet. I did not find a clear footprint-vs-drawing dimensional mismatch from the available extracted data. The official drawing PDF is the right reference for final land-pattern verification.
Recommended property updates
Per the part-project sync guidance, the properties to align from the datasheet are the exact system property names such as
Manufacturer Part Number, Manufacturer Name, Part Type, Datasheet URL, Designator Prefix, and Package or Case CodeRecommended values:
Manufacturer Part Number= USB4235-03-CManufacturer Name= GCT (Global Connector Technology)Part Type= ConnectorDatasheet URL= https://gct.co/download?type=PDFSpecification&name=usb4235-spec.pdfDesignator Prefix= J (keep)Package or Case Code= USB Type-C receptacle, vertical, top mount, 16 contacts- Description = USB Type-C USB 2.0 vertical receptacle, 16 contacts, 48 V DC, 5 A, 6.50 mm profile
Short descriptions are recommended rather than copying full datasheet sentences
Examples:
- VBUS_A, VBUS_A__1, VBUS_B, VBUS_B__1: USB bus power
- GND_A, GND_A__1, GND_B, GND_B__1: Ground return
- CC1, CC2: Configuration channel
- DP1, DP2: USB2 D+
- DN1, DN2: USB2 D-
- SBU1, SBU2: Sideband use
- SHIELD, SHIELD__1: Connector shield
I can apply the
Datasheet URL property update and then continue aligning the remaining part metadata from the official datasheet.Name
