Questions
Is there a KiCad symbol and footprint for the CH390L?
Yes. The symbol is EasyEDA_Cloud:CH390L_C42442061 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 CH390L?
LQFP-48(7x7), with 48 pins. Its footprint is drawn on this page.
Where can I order the CH390L?
JLCPCB lists it as part C42442061, with 426 in stock; the sellers' links on this page open their listings.
What can replace the CH390L?
Parts like it in the library: the W5500 by WIZNET, the CH394Q by WCH (Nanjing Qinheng Microelectronics), the DM9000AEP by DAVICOM and the DM9000CEP by DAVICOM. Check their datasheets: a part that fits the footprint may still differ in its ratings.
