Is there a KiCad symbol and footprint for the SD2085?
Yes. The symbol is EasyEDA_Cloud:SD2085 and the footprint EasyEDA_Cloud:QFN-20_L5.0-W5.0-P0.65-BL-EP, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SD2085?
QFN-20-EP(5x5), with 21 pins. Its footprint is drawn on this page.
Where is the SD2085 datasheet?
Hangzhou SDIC Microelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the SD2085?
JLCPCB lists it as part C414105, with 333 in stock; the sellers' links on this page open their listings.
What can replace the SD2085?
Parts like it in the library: the DS8500-JND+T&R by Analog Devices. Check their datasheets: a part that fits the footprint may still differ in its ratings.
