Is there a KiCad symbol and footprint for the CJ502K?
Yes. The symbol is Pinmap_Generic:Q_PMOS_1G_2S_3D and the footprint Package_TO_SOT_SMD:SOT-23, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the CJ502K?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where is the CJ502K datasheet?
Jiangsu Changjing Electronics Technology (CJ) publishes it: the Datasheet link on this page opens it.
Where can I order the CJ502K?
JLCPCB lists it as part C504057, with 29 in stock; the sellers' links on this page open their listings.
What can replace the CJ502K?
Parts like it in the library: the 2N7002K by Diodes Incorporated, the BSS138P by Nexperia, the SI2308A by UMW and the 2N7002NXAKR by Nexperia. Check their datasheets: a part that fits the footprint may still differ in its ratings.
