Is there a KiCad symbol and footprint for the SFR433K?
Yes. the footprint Crystal:Crystal_SMD_WE_CFPX-180-4Pin_3.2x2.5mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SFR433K?
SMD3225-4P, with 5 pins. Its footprint is drawn on this page.
Where is the SFR433K datasheet?
Sf publishes it: the Datasheet link on this page opens it.
Where can I order the SFR433K?
JLCPCB lists it as part C469569, with 0 in stock; the sellers' links on this page open their listings.
What can replace the SFR433K?
Parts like it in the library: the Y3225433MFC4H by JLYE, the SFR433D by Sf, the SFR433F by Sf and the LR1 433.92 by LADDER Elec. Check their datasheets: a part that fits the footprint may still differ in its ratings.
