Here is an image showing the pin diagram of this transistor.The 2SC1913A-Q transistor can have a current gain of 90 to 155. The gain of the 2SC1913A will be in the range from 65 to 330, for the 2SC1913A-P it will be in the range from 65 to 110, for the 2SC1913A-R it will be in the range from 130 to 220, for the 2SC1913A-S it will be in the range from 185 to 330.Sometimes the "2S" prefix is not marked on the package - the 2SC1913A-Q might only be marked "C1913A-Q".The complementary PNP transistor to the 2SC1913A-Q is the 2SA913A-Q.The KST43 (SOT-23) is the SMD version of the 2SC1913A-Q transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC1913A-Q with the 2SC2238A, 2SC2238B, 2SC2336, 2SC2336A, 2SC2336B, 2SC3298A, 2SC3298B, 2SC3944A, 2SC3944A-Q, 2SC4382, 2SC4883A, 2SD1264A, 2SD610, 2SD772A, 2SD772B, 2SD792A, 2SD792B, FJP5200, FJP5200O, FJPF5200, FJPF5200O, KTC2238A, KTC4370A, KTD2061, MJE15032 or MJE15032G.
