Here is an image showing the pin diagram of this transistor.The BC857AW transistor can have a current gain of 110 to 220. The gain of the BC857BW will be in the range from 200 to 450, for the BC857CW it will be in the range from 420 to 800, for the BC857W it will be in the range from 110 to 800.The complementary NPN transistor to the BC857AW is the BC847AW.You can replace the BC857AW with the 2SA1586, BC807-16W, BC807W, BC856AW, BC856W, BC860AW, BC860W, FJX2907A, FJX733, KTN2907AU or MMST2907A.
