Here is an image showing the pin diagram of this transistor.The BC849CW transistor can have a current gain of 420 to 800. The gain of the BC849AW will be in the range from 110 to 220, for the BC849BW it will be in the range from 200 to 450, for the BC849W it will be in the range from 110 to 800.The complementary PNP transistor to the BC849CW is the BC859CW.You can replace the BC849CW with the BC847CW, BC847W, BC848CW, BC848W, BC850CW or BC850W.
