Overview
The J111 is a JFET made by onsemi in a TO-92-3L package with 3 pins. TO-92-3L JFETs ROHS.
PCBKit's library has its KiCad symbol (EasyEDA_Cloud:J111, from EasyEDA) and its footprint (EasyEDA_Cloud:TO-92-3_L4.9-W3.7-P1.27-L, from EasyEDA), ready for a KiCad board. 1 are in stock at JLCPCB (part C274642). 8 open-source boards in 5 repositories on GitHub use it.

Is there a KiCad symbol and footprint for the J111?
Yes. The symbol is EasyEDA_Cloud:J111 and the footprint EasyEDA_Cloud:TO-92-3_L4.9-W3.7-P1.27-L, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the J111?
TO-92-3L, with 3 pins. Its footprint is drawn on this page.
Where is the J111 datasheet?
onsemi publishes it: the Datasheet link on this page opens it.
Where can I order the J111?
JLCPCB lists it as part C274642, with 1 in stock; the sellers' links on this page open their listings.
What can replace the J111?
Parts like it in the library: the J109 by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the J111?
8 boards in 5 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
