The 2SC1959-GR 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.The 2SC1959-GR transistor can have a current gain of 200 to 400. The gain of the 2SC1959 will be in the range from 70 to 400, for the 2SC1959-O it will be in the range from 70 to 140, for the 2SC1959-Y it will be in the range from 120 to 240.Sometimes the "2S" prefix is not marked on the package - the 2SC1959-GR might only be marked "C1959-GR".The 2SC2859 (SOT-23), 2SC2859-GR (SOT-23), 2SC4118 (SOT-323), 2SC4118-GR (SOT-323), KTC3876 (SOT-23), KTC3876GL (SOT-23), KTC3876S (SOT-23) and KTC3876S-GL (SOT-23) is the SMD version of the 2SC1959-GR transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC1959-GR with the 2N3417, 2SC2500, 2SC2500-A, 2SC2500-B, 2SC2500-C, 2SC2500-D, 2SC3916, 2SC3917, 2SC3918, 2SC3919, 2SC3920, 2SC3921, 2SC3922, 2SC3923, 2SC4408, 2SC4604, 2SD1207, 2SD1207-T, 2SD1347, 2SD1347T, 2SD1616, 2SD1616-K, 2SD1616A, 2SD1616A-K, 2SD1835, 2SD1835-T, 2SD789, KSC1008C, KSC1008CG, KSC2500, KSC2500-A, KSC2500-B, KSC2500-C, KSC2500-D, KSC5019, KSD1021, KSD1021-G, KSD1616, KSD1616-G, KSD1616A, KSD1616A-G, KSD471AC, KSD471ACG or NTE192A.
