Part Data Review and Updates
Thought for 3 mins 30 sec
I reviewed the part project against the official Molex sources and updated the missing Datasheet URL property to the official PDF.
What I found
Current stored part metadata
Table
| Field | Current value | Status |
|---|---|---|
| Manufacturer Name | Molex | OK |
| Manufacturer Part Number | 5052781233 | OK |
| Part Type | Connectors | OK but broad |
| Designator Prefix | J | OK |
| Datasheet URL | https://www.molex.com/content/dam/molex/molex-dot-com/products/automated/en-us/3dcadmodelspdf/505/505278/5052781233.pdf | Added |
Table
| Spec | Value |
|---|---|
| MPN | 5052781233 |
| Manufacturer | Molex |
| Family / description | 0.5 FFC CONN ZIF E/O BTM CONT TYPE ASSY |
| Connector type | FFC/FPC ZIF connector |
| Circuits / pin count | 12 |
| Pitch | 0.50 mm |
| Contact type | Bottom contact |
| Mounting style | Surface mount |
| Orientation | Right-angle |
| Published height | 1.2 mm |
| Status | Active |
The official Molex part page confirms the 12-circuit, 0.50 mm pitch, bottom-contact, SMT ZIF FFC/FPC connector details, while the official PDF confirms the exact MPN and circuit size.
Symbol / pin audit
- The schematic currently has 12 terminal elements, with pin numbers 1 through 12.
- All pins are currently typed as Passive.
- The symbol terminals do not have meaningful visible pin names/designators set; they appear as
~. - I did not find any populated Pin Description properties.
- The layout contains:
- 12 numbered contact pads
- 2 additional mounting/mechanical pads labeled 13 and 14
- That means the footprint appears to be modeled as 12 electrical contacts + 2 hold-down tabs/mechanical pads.
Table
| Area | Finding | Severity |
|---|---|---|
| Datasheet property | Was missing; now added | Fixed |
| Symbol pin names | Pins are not labeled with meaningful pin names, only generic terminal markers | Medium |
| Pin descriptions | Missing | Medium |
| Pin typing | All pins set to Passive; likely acceptable for a connector, but mechanical tabs should not be treated like normal signal pins if they are purely hold-down tabs | Medium |
| Pin count vs footprint | Symbol has 12 terminals, footprint appears to have 14 pads total | Important |
| Package metadata | No explicit package/case property found | Low |
The biggest thing to check next is the 12-symbol-terminals vs 14-footprint-pads situation.
This is not necessarily wrong:
- many FFC/FPC connectors have 12 electrical contacts
- plus 2 mechanical mounting tabs
But if pads 13 and 14 are mechanical-only tabs, the part project should make that clear. Right now, the schematic side only represents the 12 signal contacts, and the extra footprint pads are not documented in the symbol metadata.
Recommended cleanup
- Add a Package or Case Code property if you want the part metadata to be more complete.
- Set pin names/descriptions for pins 1-12.
- Confirm whether pads 13 and 14 are:
- mechanical hold-down tabs only, or
- pads that should exist as additional terminals in the part definition.
- If they are mechanical-only, keep them off the symbol but document that in the footprint/part metadata.
- If they are electrically meaningful, the symbol is currently incomplete.
- Datasheet URL: added successfully.
- MPN / manufacturer / basic published specs: consistent.
- Symbol: incomplete from a library-quality standpoint because pin names/descriptions are missing.
- Footprint: appears to include 2 extra mechanical pads beyond the 12 signal contacts.
- Potential mismatch: symbol has 12 terminals, footprint has 14 pads total.
If you want, I can do the next pass and populate pin names/descriptions and reconcile the 2 mounting pads properly.
Fix connector metadata
Tighten part properties
Check footprint mapping
