Questions

Is there a KiCad symbol and footprint for the BL3402?

Yes. 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 BL3402?

SOT-23, with 5 pins. Its footprint is drawn on this page.

Where is the BL3402 datasheet?

Galaxy Microelectronics publishes it: the Datasheet link on this page opens it.

Where can I order the BL3402?

JLCPCB lists it as part C21882530, with 2,930 in stock; the sellers' links on this page open their listings.

What can replace the BL3402?

Parts like it in the library: the SI2318 by GOODWORK, the 6P03 by GOODWORK, the AP3401BI by A Power microelectronics and the RRR030P03TL(ES) by ElecSuper. Check their datasheets: a part that fits the footprint may still differ in its ratings.
