Questions
Is there a KiCad symbol and footprint for the CH213K?
Yes. The symbol is OLIMEX_Diodes:CH213K and the footprint Package_TO_SOT_SMD:SOT-23-3, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the CH213K?
SOT-23-3, with 3 pins. Its footprint is drawn on this page.
Where is the CH213K datasheet?
WCH (Nanjing Qinheng Microelectronics) publishes it: the Datasheet link on this page opens it.
Where can I order the CH213K?
JLCPCB lists it as part C5456874, with 28,331 in stock; the sellers' links on this page open their listings.
What can replace the CH213K?
Parts like it in the library: the AP2331SA by Diodes Incorporated, the RT9742SNGV by Richtek Tech, the WB2967J by Waferbest and the KP3111LGA by Kiwi Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the CH213K?
51 boards in 26 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
