Here is an image showing the pin diagram of this transistor.The 2SB435-R transistor can have a current gain of 40 to 80. The gain of the 2SB435 will be in the range from 40 to 240, for the 2SB435-O it will be in the range from 70 to 140, 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-R might only be marked "B435-R".The complementary NPN transistor to the 2SB435-R is the 2SD235-R.You can replace the 2SB435-R with the 2N6107, 2N6107G, 2N6108, 2N6109, 2N6109G, 2N6110, 2N6124, 2N6125, 2N6126, 2N6132, 2N6133, 2N6134, 2N6489, 2N6489G, 2N6490, 2N6490G, 2N6491, 2N6491G, 2SA1262, 2SA1488, 2SA1488A, 2SA489, 2SA489-R, 2SA490, 2SA490-R, 2SA614, 2SA614R, 2SA671, 2SA770, 2SA771, 2SB1017, 2SB1017-R, 2SB1097, 2SB1097-M, 2SB1368, 2SB1368-R, 2SB434, 2SB434R, 2SB507, 2SB507C, 2SB596, 2SB596-R, 2SB703, 2SB703-S, 2SB707, 2SB707-R, 2SB708, 2SB708-R, 2SB747, 2SB747-R, 2SB761, 2SB761-R, 2SB761A, 2SB761A-R, 2SB762, 2SB762-R, 2SB762A, 2SB762A-R, 2SB942, 2SB942-R, 2SB942A, 2SB942A-R, 2SB996, 2SB996-R, BD202, BD204, BD242, BD242A, BD242B, BD244, BD244A, BD244B, BD302, BD304, BD534, BD534K, BD536, BD536K, BD538, BD538K, BD540, BD540A, BD540B, 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, KSA614, KSA614R, KSB1017, KSB1017-R, KSB1097, KSB1097-R, KSB596, KSB596-R, KSB707, KSB707-R, KSB708, KSB708-R, KTB1368, KTB1368R, MJE2901T, MJE2955T, MJE2955TG or NTE197.
