Overview
The SI2303 is a MOSFET made by PAKER in a SOT-23 package with 3 pins.
PCBKit's library has its KiCad symbol (EasyEDA_Cloud:AO3401_C5278897, from EasyEDA) and its footprint (Package_TO_SOT_SMD:SOT-23, from KiCad's library), ready for a KiCad board. 1,279 are in stock at JLCPCB (part C5278886).

Questions
Is there a KiCad symbol and footprint for the SI2303?
Yes. The symbol is EasyEDA_Cloud:AO3401_C5278897 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 SI2303?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where is the SI2303 datasheet?
PAKER publishes it: the Datasheet link on this page opens it.
Where can I order the SI2303?
JLCPCB lists it as part C5278886, with 1,279 in stock; the sellers' links on this page open their listings.
What can replace the SI2303?
Parts like it in the library: the AO3400 by GOODWORK, the AO3400A by Alpha & Omega Semiconductor, the AO3400A by UMW and the AO3401A by UMW. Check their datasheets: a part that fits the footprint may still differ in its ratings.
