Questions

Is there a KiCad symbol and footprint for the CH345T?

Yes. The symbol is EasyEDA_Cloud:CH345T and the footprint Package_SO:SSOP-20_5.3x7.2mm_P0.65mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the CH345T?

SSOP-20, with 20 pins. Its footprint is drawn on this page.

Where is the CH345T datasheet?

WCH (Nanjing Qinheng Microelectronics) publishes it: the Datasheet link on this page opens it.

Where can I order the CH345T?

JLCPCB lists it as part C5246448, with 120 in stock; the sellers' links on this page open their listings.

What can replace the CH345T?

Parts like it in the library: the CH376T by WCH (Nanjing Qinheng Microelectronics), the CH341T by WCH (Nanjing Qinheng Microelectronics), the MCP2200-I/SS by Microchip Technology and the MCP2210-I/SS by Microchip Technology. Check their datasheets: a part that fits the footprint may still differ in its ratings.
