The 2SC2347 is manufactured in a plastic TO-92 case. When looking at the flat side with the leads pointed downward, the three leads emerging from the transistor are, from left to right, the emitter, collector, and base leads.
Here is an image showing the pin diagram of this transistor.Sometimes the "2S" prefix is not marked on the package - the 2SC2347 might only be marked "C2347".The MMBT918 (SOT-23) is the SMD version of the 2SC2347 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC2347 with the 2N3390, 2N3391, 2N3391A, 2N3392, 2N3393, 2N3414, 2N3415, 2N3704, 2N3705, 2N3706, 2N3707, 2N3708, 2N3709, 2N3710, 2N3711, 2SC1317, 2SC1317-Q, 2SC1317-R, 2SC1317-S, 2SC1383, 2SC1383-Q, 2SC1383-R, 2SC1383-S, 2SC1518, 2SC1518-Q, 2SC1518-R, 2SC1518-S, 2SC1959, 2SC1959-GR, 2SC1959-O, 2SC1959-Y, 2SC2001, 2SC2001-K, 2SC2001-L, 2SC2001-M, 2SC2120, 2SC2120-O, 2SC2120-Y, 2SC2236, 2SC2236-O, 2SC2236-Y, 2SC2328A, 2SC2328A-O, 2SC2328A-Y, 2SC2500, 2SC2500-A, 2SC2500-B, 2SC2500-C, 2SC2500-D, 2SC2710, 2SC2710-O, 2SC2710-Y, 2SC3202, 2SC3202-O, 2SC3202-Y, 2SC3203, 2SC3203-O, 2SC3203-Y, 2SC3205, 2SC3205-O, 2SC3205-Y, 2SC3242, 2SC3242-E, 2SC3242-F, 2SC3242-G, 2SC3242A, 2SC3242A-E, 2SC3242A-F, 2SC3246, 2SC3246-G, 2SC3246-H, 2SC3246-J, 2SC3246-K, 2SC3266, 2SC3266-BL, 2SC3266-GR, 2SC3266-Y, 2SC3940, 2SC3940-Q, 2SC3940-R, 2SC3940-S, 2SC4208, 2SC4208-Q, 2SC4208-R, 2SC4208-S, 2SC458, 2SC458-B, 2SC458-C, 2SC458-D, 2SC460, 2SC460A, 2SC460B, 2SC460C, 2SC461, 2SC461A, 2SC461B, 2SC461C, 2SC4682, 2SC536, 2SC536-D, 2SC536-E, 2SC536-F, 2SC536-G, 2SC536-H, 2SC828, 2SC828-Q, 2SC828-R, 2SC828-S, 2SD1513, 2SD1513-K, 2SD1513-L, 2SD1513-U, 2SD467, 2SD467-B, 2SD467-C, 2SD468, 2SD468-B, 2SD468-C, 2SD471, 2SD471K, 2SD471L, 2SD471M, 2SD545, 2SD545-D, 2SD545-E, 2SD545-F, 2SD545-G, 2SD592, 2SD592-Q, 2SD592-R, 2SD592-S, 2SD592A, 2SD592A-Q, 2SD592A-R, 2SD592A-S, 2SD734, 2SD734-D, 2SD734-E, 2SD734-F, 2SD734-G, 2SD965, 2SD965Q, 2SD965R, BC168, BC168A, BC168B, BC168C, BC169, BC169A, BC169B, BC169C, BC184L, BC184LC, KSC1730, KSC1730O, KSC1730R, KSC1730Y, KSC2328A, KSC2328A-O, KSC2328A-Y, KSC2500, KSC2500-A, KSC2500-B, KSC2500-C, KSC2500-D, KSC5019, KSC5019-L, KSC5019-M, KSC5019-N, KSC5019-P, KSD1020, KSD1020-G, KSD1020-Y, KSD1021, KSD1021-G, KSD1021-Y, KSD261C, KSD261CG, KSD261CY, KSD471AC, KSD471ACG, KSD471ACY, KTC2874, KTC2874-A, KTC2874-B, KTC3192, KTC3192O, KTC3192R, KTC3192Y, KTC3197, KTC3202, KTC3202O, KTC3202Y, KTC3203, KTC3203O, KTC3203Y, KTC3204, KTC3204O, KTC3204Y, KTC3205, KTC3205O, KTC3205Y, KTC3210, KTC3210O, KTC3210Y, KTC3211, KTC3211GR, KTC3211O, KTC3211Y, KTC3266, KTC3266-GR, KTC3266-Y, KTD1146, KTD1146GR, KTD1146O, KTD1146Y, PN3641 or PN3643.
