Here is an image showing the pin diagram of this transistor.The BC849W transistor can have a current gain of 110 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 BC849CW it will be in the range from 420 to 800.The complementary PNP transistor to the BC849W is the BC859W.You can replace the BC849W with the BC847W, BC848W or BC850W.
