Questions
Is there a KiCad symbol and footprint for the STDCSW2-48M?
Yes. the footprint EasyEDA_Cloud:CRYSTAL-SMD_4P-L2.5-W2.0-BL, both drawn on this page. PCBKit places them on a board for you when you design with it.
Where is the STDCSW2-48M datasheet?
NDK publishes it: the Datasheet link on this page opens it.
Where can I order the STDCSW2-48M?
JLCPCB lists it as part C20010649, with 0 in stock; the sellers' links on this page open their listings.
What can replace the STDCSW2-48M?
Parts like it in the library: the NZ2520SB-27MHZ/NSA3415E by NDK, the S252024M12PF10PPM by SST, the S252025M10PF10PPM by SST and the S252026M9PF10PPM by SST. Check their datasheets: a part that fits the footprint may still differ in its ratings.
