# Hanrun HR873169AE Ethernet Socket Reference Shematic

## Question

Asked by Argeolog on 2023-06-11 in Ethernet Chips.

I want to use Hanrun HR873169AE socket. BUT TCT and TCT Pins are Shorted. How Should I Connect Wiznet5500 According to Socket? Can you share a sample schematic?
Thank you.

dear friend, i made w5500 connection before. Now the situation is different. Tct and RCT terminals are combined in this socket. Please look at the red mark in the picture.

Hi [@Argeolog](https://maker.wiznet.io/u/argeolog) RJ45 jack types with a combination of RTC and TCT are not available for the W5500.
