Overview
The SI2302 is a MOSFET made by FMS in a SOT-23 package with 3 pins. 1 N-channel 1.25V 2.9nC@4.5V 20V 280pF 29pF 3A 46pF 700mW SOT-23 MOSFETs ROHS.
PCBKit's library has its KiCad symbol (Pinmap_Generic:Q_NMOS_1G_2S_3D, from PCBKit's generic symbols) and its footprint (Package_TO_SOT_SMD:SOT-23, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C163505).

Questions
Is there a KiCad symbol and footprint for the SI2302?
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 SI2302?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where is the SI2302 datasheet?
FMS publishes it: the Datasheet link on this page opens it.
Where can I order the SI2302?
JLCPCB lists it as part C163505, with 0 in stock; the sellers' links on this page open their listings.
What can replace the SI2302?
Parts like it in the library: the AO3400 by GOODWORK, the AP2300 by ALLPOWER, the AO3400A by Alpha & Omega Semiconductor and the AO3400A by UMW. Check their datasheets: a part that fits the footprint may still differ in its ratings.
