Hi, The footprint (RJ45-LIGHT-90) for LCSC Component C34677 is incorrect according to the datasheet. The spacing between the LED pins (pins 12, 11, 10, 8) is 2.54. The incorrect value (11.43mm) was used in the design of the current footprint. 11.43mm refers to the spacing between the plastic locating pegs. This is the current footprint ![currentFootprint.png](//image.easyeda.com/pullimage/ks0ITUE6sTdZ3wwwwJZR0lBLqzveTd0edoeEyqTJ.png) And this is what the datasheet says it should be ![datasheet.png](//image.easyeda.com/pullimage/RqQF8rvoz1PgDUjVE0lGpI3LADdA2pRLFWQnWfhG.png) Finally, here is a product picture showing the spacing for the LED pins. ![product.png](//image.easyeda.com/pullimage/iuunNqFEy6wnlyHA2PzrphJxA8LBN1OsOEjkWgRp.png)

@LCSC URGENT: I think the footprint pin connections are incorrect compared to the datasheet. I noticed that the datasheet shows P4 as no-connect, but it is shown in the schematic lib as "TC". I think all of the pads are incorrect? It looks like someone draw them using the pin numbers inside the RJ45 instead of the pins outside. Here is the datasheet showing P7 as RD- ![rj45.png](//image.easyeda.com/pullimage/W7fpUdh6K29sksI26mUDtXtgDdr8oLBYT5lp2DaF.png) The schematic lib in EasyEDA shows RD- as pin 6. The same for all the other pins. ![rj45_schem.png](//image.easyeda.com/pullimage/bYFRQQPgkx1XCaDA0BmeJOjNhrb4O5qAJEC4N6it.png)

The Schematic Symbol for C34677/HY951180A is now correct to the datasheet. The PCB Footprint has been slightly modified to correct the mounting holes to 3.2mm diameter holes rather than PTH holes.

Thank you! The new schematic symbol looks great!
