Here is an image showing the pin diagram of this transistor.The 2SA816-Y transistor can have a current gain of 120 to 240. The gain of the 2SA816 will be in the range from 70 to 240, for the 2SA816-O it will be in the range from 70 to 140.Sometimes the "2S" prefix is not marked on the package - the 2SA816-Y might only be marked "A816-Y".The complementary NPN transistor to the 2SA816-Y is the 2SC1626-Y.The 2SA1202 (SOT-89), 2SA1202-Y (SOT-89), 2SA1368 (SOT-89), 2SB805 (SOT-89), 2SD1006 (SOT-89), FMMTA56 (SOT-23), KST56 (SOT-23), KTA1662 (SOT-89), KTA1662Y (SOT-89), MMBTA56 (SOT-23), PMBTA56 (SOT-23), PZTA56 (SOT-223) and SMBTA56 (SOT-23) is the SMD version of the 2SA816-Y transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SA816-Y with the 2SA1078, 2SA1293, 2SA1293-Y, 2SA1306, 2SA1306-Y, 2SA1308, 2SA1308-Y, 2SA1329, 2SA1329-Y, 2SA1388, 2SA1388-Y, 2SA1452, 2SA1452-Y, 2SA1452A, 2SA1452A-Y, 2SA1488A, 2SA1634, 2SA1635, 2SA1667, 2SA1859, 2SA769, 2SA771, 2SA814, 2SA814-Y, 2SA815, 2SA815-Y, 2SA913, 2SA968, 2SA968Y, 2SA985, 2SA985A, 2SB1016, 2SB1016-Y, 2SB1016A, 2SB1016A-Y, 2SB1017, 2SB1017-Y, 2SB1018, 2SB1018-Y, 2SB1018A, 2SB1018A-Y, 2SB1085, 2SB1186, 2SB1367, 2SB1367-Y, 2SB1368, 2SB1368-Y, 2SB1548A, 2SB1548A-P, 2SB546, 2SB546-Y, 2SB547, 2SB595, 2SB595-Y, 2SB596, 2SB596-Y, 2SB633, 2SB761A, 2SB761A-P, 2SB762A, 2SB762A-P, 2SB870, 2SB940, 2SB940-P, 2SB941A, 2SB941A-P, 2SB942A, 2SB942A-P, 2SB943, 2SB944, 2SB945, 2SB946, 2SB992, 2SB992-Y, 2SB995, 2SB995-Y, 2SB996, 2SB996-Y, BD240B, BD240C, BD242B, BD242C, BD244B, BD244C, BD538, BD540B, BD540C, BD544B, BD544C, BD546B, BD546C, BD800, BD802, BD810, BD938, BD938F, BD940, BD940F, BD942, BD942F, BD952, BD954, BD956, BDT30B, BDT30C, BDT84, BDT84F, BDT86, BDT86F, BDT88, BDT88F, BDX78, D44C10, D44C11, D44C12, D45C10, D45C11, D45C12, D45H11, D45H11FP, KSB1017, KSB1017-Y, KSB546, KSB546-Y, KSB596, KSB596-Y, KTA1038, KTA1038-Y, KTA1049, KTA1049Y, KTA1659, KTA1659Y, KTA968, KTA968Y, KTB1367, KTB1367Y, KTB1368, KTB1368Y, MJE15029, MJE15029G, MJE15031, MJE15031G, MJF15031, MJF15031G, TTA1452B or TTB1452B.
