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  And this is what the datasheet says it should be  Finally, here is a product picture showing the spacing for the LED pins.
