Is there a KiCad symbol and footprint for the CH596D?
Yes. the footprint EasyEDA_Cloud:QFN-20_L3.0-W3.0-P0.40-BL-EP1.9, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the CH596D?
QFN-20(3x3), with 21 pins. Its footprint is drawn on this page.
Where can I order the CH596D?
JLCPCB lists it as part C54973464, with 0 in stock; the sellers' links on this page open their listings.
What can replace the CH596D?
Parts like it in the library: the FR8003A by FREQCHIP. Check their datasheets: a part that fits the footprint may still differ in its ratings.
