Here is an image showing the pin diagram of this transistor.The 2SB966 transistor can have a current gain of 60 to 320. The gain of the 2SB966-P will be in the range from 160 to 320, for the 2SB966-Q it will be in the range from 100 to 200, for the 2SB966-R it will be in the range from 60 to 120.Sometimes the "2S" prefix is not marked on the package - the 2SB966 might only be marked "B966".The complementary NPN transistor to the 2SB966 is the 2SD1289.You can replace the 2SB966 with the 2SA1106, 2SA1633 or 2SA1788.
