Here is an image showing the pin diagram of this transistor.The 2SA914-R transistor can have a current gain of 130 to 220. The gain of the 2SA914 will be in the range from 90 to 450, for the 2SA914-Q it will be in the range from 90 to 155, for the 2SA914-S it will be in the range from 185 to 330, for the 2SA914-T it will be in the range from 260 to 450.Sometimes the "2S" prefix is not marked on the package - the 2SA914-R might only be marked "A914-R".The complementary NPN transistor to the 2SA914-R is the 2SC1953-R.The 2SA1200 (SOT-89), 2SA1200-Y (SOT-89), KTA1660 (SOT-89) and KTA1660Y (SOT-89) is the SMD version of the 2SA914-R transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SA914-R with the 2SA1021, 2SA1142, 2SA1144, 2SA1144-Y, 2SA1209, 2SA1210, 2SA1220A, 2SA1248, 2SA1249, 2SA1322, 2SA1352, 2SA1353, 2SA1360, 2SA1360-Y, 2SA1380, 2SA1381, 2SA1406, 2SA1407, 2SA1477, 2SA1478, 2SA1479, 2SA1480, 2SA1507, 2SA1540, 2SA1541, 2SA795, 2SA795-R, 2SA795A, 2SA795A-R, 2SB1109, 2SB1110, HSB1109, KSA1142, KSA1220A, KSA1381, KSE350, KTA1700, KTA1700-Y, MJE350 or MJE350G.
