Questions

Is there a KiCad symbol and footprint for the CH394Q?

Yes. The symbol is EasyEDA_Cloud:CH394Q and the footprint Package_QFP:LQFP-48_7x7mm_P0.5mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the CH394Q?

LQFP-48(7x7), with 48 pins. Its footprint is drawn on this page.

Where is the CH394Q datasheet?

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

Where can I order the CH394Q?

JLCPCB lists it as part C46061830, with 1,257 in stock; the sellers' links on this page open their listings.

What can replace the CH394Q?

Parts like it in the library: the W5500 by WIZNET, the DM9000AEP by DAVICOM, the DM9000CEP by DAVICOM and the CH390L by WCH (Nanjing Qinheng Microelectronics). Check their datasheets: a part that fits the footprint may still differ in its ratings.
