Questions

Is there a KiCad symbol and footprint for the CJ2302?

Yes. The symbol is Pinmap_Generic:Q_NMOS_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 CJ2302?

SOT-23, with 3 pins. Its footprint is drawn on this page.

Where is the CJ2302 datasheet?

Jiangsu Changjing Electronics Technology (CJ) publishes it: the Datasheet link on this page opens it.

Where can I order the CJ2302?

JLCPCB lists it as part C2910175, with 0 in stock; the sellers' links on this page open their listings.

What can replace the CJ2302?

Parts like it in the library: the AO3400 by GOODWORK, the AP2300 by ALLPOWER, the SI2302-2.3A-JSM by JSMSEMI and the AO3400A by Alpha & Omega Semiconductor. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the CJ2302?

19 boards in 15 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
