Here is an image showing the pin diagram of this transistor.Sometimes the "2S" prefix is not marked on the package - the 2SC2194A might only be marked "C2194A".The complementary PNP transistor to the 2SC2194A is the 2SA962A.The 2SC3444 (SOT-89), BCP55 (SOT-223) and BCX55 (SOT-89) is the SMD version of the 2SC2194A transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC2194A with the BD517, BD519, BD525, BD527, BD529 or NTE188.
