Part Information Review and Correction

flux

I reviewed the current part project against the available project metadata, symbol terminals, and footprint pads.
Summary
  • Datasheet URL is already set, so I did not update it.
  • The part project currently has 16 schematic terminals but the footprint has 18 pads: 16 numbered pads plus 2 extra mount/shield pads. That is the biggest mismatch I found.
  • The symbol metadata is incomplete: all terminals have Pin Type = Unspecified, and I do not see any pin descriptions populated.
  • The project metadata has at least one likely classification problem: Part Type = Optoelectronic Devices does not match a MagJack / RJ45 connector with integrated magnetics.
Current project information Project metadata

Manufacturer Part Number1840750-7Looks consistent with the project
Manufacturer NameTE ConnectivityNeeds verification; web sources are inconsistent
Datasheet URLPresentNo update needed
Designator PrefixJCorrect for a connector
Part TypeOptoelectronic DevicesLikely incorrect for this part
DescriptionModular Connectors / Ethernet Connectors 1X1 MAG45 GIG 7G61P9 G/G REAR LED PINUnderstandable, but messy and not ideal library metadata
Symbol / terminal audit
The schematic contains 16 terminal components, numbered 1–16. From the current symbol:
  • Pins 1–10 appear to be magnetics / channel pins
  • Pins 11–14 appear to be LED pins
  • Pins 15–16 exist as bare numeric labels
  • No terminal has a Pin Description
  • Every terminal has Pin Type = Unspecified
That kind of incomplete terminal metadata is exactly the sort of issue the part-sync workflow recommends flagging and fixing, especially pin count, pin types, and descriptions. The datasheet should be treated as the source of truth, and the pin count should match exactly, including extra pads when the datasheet counts them.
Footprint audit
The footprint contains:
  • 16 main pads matching the symbol’s numbered electrical pins
  • 2 additional pads inside the mounts container, labeled 17 and 18
That means the footprint has 18 total pads, while the symbol exposes only 16 terminals.
Likely mismatches 1. Symbol-to-footprint pin count mismatch
This is the clearest issue:
  • Symbol: 16 terminals
  • Footprint: 18 pads
If pads 17 and 18 are mechanical shield / chassis / mount tabs and the datasheet treats them as pins, then the symbol is incomplete. The recommended rule for part verification is to make the project pin count match the datasheet exactly, including extra pads when listed.
2. Missing pin metadata
All terminals are currently missing the metadata normally expected in a validated part project:
  • Pin Type
  • Pin Description
The sync guidance explicitly calls for exact pin-number verification plus short pin descriptions and mapped pin types.
3. Poor / ambiguous terminal naming
A few terminal labels look weak for a library-quality part:
  • descriptive names exist for most signal pins
  • but pins 15 and 16 are just numeric labels
  • the label VCC(COMMON_CT_ looks truncated
Those are strong indicators the symbol likely needs cleanup against the datasheet pin table.
4. Part Type likely wrong
Optoelectronic Devices does not fit a 1-port RJ45 MagJack with integrated magnetics. This should more likely be categorized as a Connector. The part-sync guidance specifically says to correct project metadata when the functional category is wrong.
Key specs I could confirm
From the currently linked/discovered distributor metadata, this part appears to be:
  • 1-port RJ45 connector
  • integrated magnetics
  • 10/100/1000 Base-T
  • through-hole
  • rear LED version
  • 8-position contact interface
I’m treating those as provisional because the linked PDF itself did not fully parse in-session, and the distributor/manufacturer attribution across search results is inconsistent.

Recommended next step
I can clean this part project up for you by:
  • correcting the project metadata
  • adding or exposing the missing pads 17/18 in the symbol if appropriate
  • assigning Pin Type
  • adding Pin Description
  • fixing truncated or non-descriptive terminal names
If you want, I can do that next.
