Here is an image showing the pin diagram of this transistor.The 2SC4161-N transistor can have a current gain of 30 to 50. The gain of the 2SC4161 will be in the range from 15 to 50, for the 2SC4161-L it will be in the range from 15 to 30, for the 2SC4161-M it will be in the range from 20 to 40.Sometimes the "2S" prefix is not marked on the package - the 2SC4161-N might only be marked "C4161-N".You can replace the 2SC4161-N with the 2SC2335, 2SC2335-L, 2SC2898, 2SC3039, 2SC3039-N, 2SC4106, 2SC4106N, 2SC4107, 2SC4107-N, 2SC4108, 2SC4108-N, 2SC4162, 2SC4162-N, 2SC4163, 2SC4163-N, 2SC4164, 2SC4164-N, 2SC4242, FJP13007, KSC2335, KSC2335-O, KSE13007, KSE13007F, MJE13007, MJE13007A, MJE13007G or STD13007F.
