Here is an image showing the pin diagram of this transistor.The 2SB931-P transistor can have a current gain of 130 to 260. The gain of the 2SB931 will be in the range from 90 to 260, for the 2SB931-Q it will be in the range from 90 to 180.Sometimes the "2S" prefix is not marked on the package - the 2SB931-P might only be marked "B931-P".The complementary NPN transistor to the 2SB931-P is the 2SD1254-P.You can replace the 2SB931-P with the 2SB932, 2SB932-P, 2SB933, 2SB933-P, 2SB934 or 2SB934-P.
