Here is an image showing the pin diagram of this transistor.Sometimes the "2S" prefix is not marked on the package - the 2SA1214 might only be marked "A1214".The 2SA1364 (SOT-89) is the SMD version of the 2SA1214 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SA1214 with the 2SB744A, BD190, BD236, BD236G, BD238, BD238G, BD378, BD380, KSB744A, MJE235, MJE252 or MJE254.
