Here is an image showing the pin diagram of this transistor.The 2SB435-O transistor can have a current gain of 70 to 140. The gain of the 2SB435 will be in the range from 40 to 240, for the 2SB435-R it will be in the range from 40 to 80, for the 2SB435-Y it will be in the range from 120 to 240.Sometimes the "2S" prefix is not marked on the package - the 2SB435-O might only be marked "B435-O".The complementary NPN transistor to the 2SB435-O is the 2SD235-O.The 2DA1213 (SOT-89), 2DA1213O (SOT-89), 2SA1213 (SOT-89) and 2SA1213-O (SOT-89) is the SMD version of the 2SB435-O transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SB435-O with the 2N6107, 2N6107G, 2N6108, 2N6109, 2N6109G, 2N6110, 2N6489, 2N6489G, 2N6490, 2N6490G, 2N6491, 2N6491G, 2SA1012, 2SA1012O, 2SA1262, 2SA1279, 2SA1279-O, 2SA1288, 2SA1288-Q, 2SA1289, 2SA1289-Q, 2SA1290, 2SA1290-Q, 2SA1291, 2SA1291-Q, 2SA1293, 2SA1293-O, 2SA1307, 2SA1307-O, 2SA1308, 2SA1308-O, 2SA1328, 2SA1328-O, 2SA1329, 2SA1329-O, 2SA1388, 2SA1388-O, 2SA1451, 2SA1451-O, 2SA1451A, 2SA1451A-O, 2SA1452, 2SA1452-O, 2SA1452A, 2SA1452A-O, 2SA1469, 2SA1469-Q, 2SA1470, 2SA1470-Q, 2SA1471, 2SA1471-Q, 2SA1488, 2SA1488A, 2SA1634, 2SA1635, 2SA1725, 2SA1725-P, 2SA1726, 2SA1726-P, 2SA1869, 2SA1869O, 2SA489, 2SA489-O, 2SA490, 2SA490-O, 2SA614, 2SA614O, 2SA671, 2SA768, 2SA769, 2SA770, 2SA771, 2SB1015, 2SB1017, 2SB1017-O, 2SB1018, 2SB1018-O, 2SB1018A, 2SB1018A-O, 2SB1019, 2SB1019-O, 2SB1097, 2SB1133, 2SB1133-Q, 2SB1134, 2SB1134-Q, 2SB1135, 2SB1135-Q, 2SB1136, 2SB1136-Q, 2SB1185, 2SB1187, 2SB1274, 2SB1366, 2SB1368, 2SB1368-O, 2SB1548, 2SB1548-Q, 2SB1548A, 2SB1548A-Q, 2SB434, 2SB434O, 2SB507, 2SB553, 2SB553-O, 2SB565, 2SB566, 2SB566A, 2SB596, 2SB596-O, 2SB703, 2SB707, 2SB708, 2SB747, 2SB761, 2SB761-Q, 2SB761A, 2SB761A-Q, 2SB762, 2SB762-Q, 2SB762A, 2SB762A-Q, 2SB824, 2SB824-Q, 2SB825, 2SB825-Q, 2SB826, 2SB826-Q, 2SB834, 2SB857, 2SB858, 2SB870, 2SB941, 2SB941-Q, 2SB941A, 2SB941A-Q, 2SB942, 2SB942-Q, 2SB942A, 2SB942A-Q, 2SB945, 2SB946, 2SB947A, 2SB948A, 2SB992, 2SB992-O, 2SB993, 2SB993-O, 2SB994, 2SB996, 2SB996-O, BD202, BD204, BD242, BD242A, BD242B, BD244, BD244A, BD244B, BD302, BD304, BD534, BD536, BD538, BD540, BD540A, BD540B, BD544, BD544A, BD544B, BD546, BD546A, BD546B, BD706, BD708, BD710, BD738, BD744, BD744A, BD744B, BD796, BD798, BD800, BD808, BD810, BD906, BD908, BD910, BD934, BD934F, BD936, BD936F, BD938, BD938F, BD950, BD952, BDT82, BDT82F, BDT84, BDT84F, BDT92, BDT92F, BDT94, BDT94F, BDX78, D44C10, D44C11, D44C12, D44C4, D44C5, D44C6, D44C7, D44C8, D44C9, D45C10, D45C11, D45C12, D45C4, D45C5, D45C6, D45C7, D45C8, D45C9, D45H11, D45H11FP, D45H8, KSA614, KSA614O, KSB1015, KSB1017, KSB1017-O, KSB1097, KSB596, KSB596-O, KSB707, KSB708, KSB834, KTB1366, KTB1368, KTB1368O, KTB988 or NTE197.
