Here is an image showing the pin diagram of this transistor.The BC849BW transistor can have a current gain of 200 to 450. The gain of the BC849AW will be in the range from 110 to 220, for the BC849CW it will be in the range from 420 to 800, for the BC849W it will be in the range from 110 to 800.The complementary PNP transistor to the BC849BW is the BC859BW.You can replace the BC849BW with the 2SC4116, BC817W, BC847BW, BC847W, BC848BW, BC848W, BC850BW, BC850W or FJX945.
