Is there a KiCad symbol and footprint for the J109?
Yes. 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 J109?
TO-92-3L, with 3 pins. Its footprint is drawn on this page.
Where is the J109 datasheet?
onsemi publishes it: the Datasheet link on this page opens it.
Where can I order the J109?
JLCPCB lists it as part C896738, with 248 in stock; the sellers' links on this page open their listings.
What can replace the J109?
Parts like it in the library: the J111 by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the J109?
3 boards in 3 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
