Is there a KiCad symbol and footprint for the NTE172A?
Yes. The symbol is EasyEDA_Cloud:NTE172A and the footprint Package_TO_SOT_THT:TO-92L, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the NTE172A?
TO-92, with 3 pins. Its footprint is drawn on this page.
Where is the NTE172A datasheet?
NTE Electronics publishes it: the Datasheet link on this page opens it.
Where can I order the NTE172A?
JLCPCB lists it as part C6943647, with 0 in stock; the sellers' links on this page open their listings.
What can replace the NTE172A?
Parts like it in the library: the BC517-D74Z by onsemi, the ZTX605 by Diodes Incorporated, the ZTX705 by Diodes Incorporated and the ZTX614 by Diodes Incorporated. Check their datasheets: a part that fits the footprint may still differ in its ratings.
