Why is it so hard to find a replacement USB-C connector for the Poco F5?

Hello! My Poco F5’s charging port is damaged, and I want to replace just the USB-C connector. Oddly, the Poco F5 seems to be one of the only phones for which you can’t find the charging connector separately. Even the Poco F5 Pro’s charging connector is available on AliExpress.

Is there any particular reason why the Poco F5’s connector is so difficult to find? Is it a proprietary connector, or is there another compatible connector from a different Xiaomi/Redmi/POCO model that I could use?
