Here is an image showing the pin diagram of this transistor.The 2SC4208 transistor can have a current gain of 80 to 340. The gain of the 2SC4208-Q will be in the range from 80 to 170, for the 2SC4208-R it will be in the range from 120 to 240, for the 2SC4208-S it will be in the range from 170 to 340.Sometimes the "2S" prefix is not marked on the package - the 2SC4208 might only be marked "C4208".The complementary PNP transistor to the 2SC4208 is the 2SC4208.The 2SC2859 (SOT-23), 2SC4118 (SOT-323), KTC3876 (SOT-23) and KTC3876S (SOT-23) is the SMD version of the 2SC4208 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC4208 with the 2N3394, 2SC1959, 2SC3916, 2SC3917, 2SC3918, 2SC3919, 2SC3920, 2SC3921, 2SC3922, 2SC3923, 2SC4208A or 2SD545.
