Here is an image showing the pin diagram of this transistor.The BC857CW transistor can have a current gain of 420 to 800. The gain of the BC857AW will be in the range from 110 to 220, for the BC857BW it will be in the range from 200 to 450, for the BC857W it will be in the range from 110 to 800.The complementary NPN transistor to the BC857CW is the BC847CW.You can replace the BC857CW with the BC856CW, BC856W, BC860CW or BC860W.
