Here is an image showing the pin diagram of this transistor.The 2SC2785-RF transistor can have a current gain of 110 to 180. The gain of the 2SC2785 will be in the range from 110 to 600, for the 2SC2785-EF it will be in the range from 250 to 400, for the 2SC2785-FF it will be in the range from 200 to 320, for the 2SC2785-HF it will be in the range from 170 to 270, for the 2SC2785-JF it will be in the range from 135 to 220, for the 2SC2785-KF it will be in the range from 300 to 600.Sometimes the "2S" prefix is not marked on the package - the 2SC2785-RF might only be marked "C2785-RF".The complementary PNP transistor to the 2SC2785-RF is the 2SA1175-RF.The 2SC1623 (SOT-23), 2SC1623-L4 (SOT-23), KSC1623 (SOT-23), KSC1623-O (SOT-23) and MMBT2484 (SOT-23) is the SMD version of the 2SC2785-RF transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC2785-RF with the 2N3416, 2SC1318, 2SC1384, 2SC1627, 2SC1627A, 2SC1815, 2SC2000, 2SC2000-K, 2SC2002, 2SC2002-M, 2SC2003, 2SC2003-M, 2SC2274, 2SC2274-E, 2SC2274K, 2SC2274K-E, 2SC2277, 2SC2277C, 2SC2310, 2SC2310-B, 2SC2458, 2SC2655, 2SC2960, 2SC2960-E, 2SC3114, 2SC3114-R, 2SC3198, 2SC3199, 2SC3243, 2SC3243-D, 2SC3244, 2SC3244-D, 2SC3328, 2SC3330, 2SC3330-R, 2SC3331, 2SC3331-R, 2SC3382, 2SC3382-R, 2SC3383, 2SC3383-R, 2SC3708, 2SC3708-R, 2SC3916, 2SC3917, 2SC3918, 2SC3919, 2SC3920, 2SC3921, 2SC3922, 2SC3923, 2SC3940A, 2SC4208A, 2SC945, 2SC945R, 2SD1207, 2SD1207-R, 2SD1347, 2SD1347R, 2SD1835, 2SD1835-R, 2SD438, 2SD438-E, 2SD667, 2SD667A, 2SD667AC, 2SD667C, 2SD789, 2SD789-B, 2SD863, 2SD863-E, BC182LB, C1815, C945, H945, H945-R, KSC1008C, KSC1815, KSC2331, KSC945C, KSP8098C, KSP8099C, KTC1006, KTC1008, KTC1008-Y, KTC3198, KTC3199, KTC3209, KTC3227, KTD863 or KTD863-Y.
