Here is an image showing the pin diagram of this transistor.The 2SA1217-Y transistor can have a current gain of 120 to 240. The gain of the 2SA1217 will be in the range from 80 to 240, for the 2SA1217-O it will be in the range from 80 to 160.Sometimes the "2S" prefix is not marked on the package - the 2SA1217-Y might only be marked "A1217-Y".The complementary NPN transistor to the 2SA1217-Y is the 2SC2877-Y.The 2DA1213 (SOT-89), 2DA1213Y (SOT-89), 2SA1213 (SOT-89), 2SA1213-Y (SOT-89) and BDP948 (SOT-223) is the SMD version of the 2SA1217-Y transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SA1217-Y with the 2SA1359, 2SA1359-Y, 2SB1143, 2SB1165, 2SB1166, 2SB744, 2SB744A, 2SB986, BD132, BD176, BD176-16, BD178, BD180, BD180G, BD188, BD190, BD786, BD788, BD788G, BD790, KSB744, KSB744A, KSE170, KSE171, KSE172, MJE170, MJE170G, MJE171, MJE171G, MJE172, MJE172G, MJE232, MJE235 or MJE252.
