Overview
The SMP4338 is a JFET made by InterFET in a SOT-23-3 package with 3 pins. -55℃~+150℃ 1 N-channel 2.5kΩ 350mW 3pF 600uA N-Channel SOT-23-3 JFETs ROHS.
PCBKit's library has its KiCad symbol (EasyEDA_Cloud:SMP4338, from EasyEDA) and its footprint (Package_TO_SOT_SMD:SOT-23-3, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C20516378).

Questions
Is there a KiCad symbol and footprint for the SMP4338?
Yes. The symbol is EasyEDA_Cloud:SMP4338 and the footprint Package_TO_SOT_SMD:SOT-23-3, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SMP4338?
SOT-23-3, with 3 pins. Its footprint is drawn on this page.
Where is the SMP4338 datasheet?
InterFET publishes it: the Datasheet link on this page opens it.
Where can I order the SMP4338?
JLCPCB lists it as part C20516378, with 0 in stock; the sellers' links on this page open their listings.
What can replace the SMP4338?
Parts like it in the library: the 2SK208-GR by QNH, the 2SK208-Y by QNH, the IF4500ST3 by InterFET and the BFR31L by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
