Is there a KiCad symbol and footprint for the 2SB647?
Yes. 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 2SB647?
TO-92L, with 3 pins. Its footprint is drawn on this page.
Where can I order the 2SB647?
JLCPCB lists it as part C47089402, with 500 in stock; the sellers' links on this page open their listings.
What can replace the 2SB647?
Parts like it in the library: the SS8050D331 by ALJ, the SS8550D331 by ALJ, the SS8050 by Jiangsu Changjing Electronics Technology (CJ) and the SS8050-TA(RANGE:160-300) by Jiangsu Changjing Electronics Technology (CJ). Check their datasheets: a part that fits the footprint may still differ in its ratings.
