Questions

Is there a KiCad symbol and footprint for the AO3402?

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 AO3402?

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

Where is the AO3402 datasheet?

GOODWORK publishes it: the Datasheet link on this page opens it.

Where can I order the AO3402?

JLCPCB lists it as part C2938369, with 200,353 in stock; the sellers' links on this page open their listings.

What can replace the AO3402?

Parts like it in the library: the AO3400A by Alpha & Omega Semiconductor, the AO3400A by UMW, the AO3401A by UMW and the AO3400 by Guangdong Hottech. Check their datasheets: a part that fits the footprint may still differ in its ratings.
