Questions

Is there a KiCad symbol and footprint for the FST50_04EL?

Yes. The symbol is EasyEDA_Cloud:FST50_04EL and the footprint EasyEDA_Cloud:WIRELM-SMD_FST50_04E, both drawn on this page. PCBKit places them on a board for you when you design with it.

Where is the FST50_04EL datasheet?

FST publishes it: the Datasheet link on this page opens it.

Where can I order the FST50_04EL?

JLCPCB lists it as part C2686163, with 0 in stock; the sellers' links on this page open their listings.

What can replace the FST50_04EL?

Parts like it in the library: the FST50_04E by FST, the ESP32-WROOM-32E-N4 by Espressif Systems, the ESP-12F(ESP8266MOD) by Ai-Thinker and the ESP32-WROOM-32 by Espressif Systems. Check their datasheets: a part that fits the footprint may still differ in its ratings.
