I have a Dell Latitude 5530 with a damaged RJ45 network connector. See the attached pictures.
Have already searched on Farnell / Aliexpress / Ebay and had contact with several suppliers on Aliexpress and Ebay, but they cannot deliver this connector.
Is there someone inside the EU, who has these connector(s) or perhaps defective motherboard(s) for these laptop models I have mentioned in the topic title.

Hi,
I'm working on the TPM chip in a Dell Latitude 5420 Rugged. It contains a NPCT754J chip, but I cannot find pin-out for this chip. I have checked the service manual; https://dl.dell.com/topicspdf/latitu...nual_en-us.pdf - but it's not detailed enough to contain this information.
I've also checked Novoton's own documentation of the chip here; https://csrc.nist.gov/CSRC/media/pro.../140sp3187.pdf and here; https://commoncriteriaportal.org/fil...ible-cc-2018_6... -
