It has been a couple years, but iirc the BF862 back then had a pretty unique combination of low capacitance, low e_n and a low 1/f knee. The 2SK2394 is also earmarked for use as an AM radio amplifier, same as the BF862, which probably also explains why these went from jellybean to rarity some time ago...
