Here is an image showing the pin diagram of this transistor.The 2SB1140 transistor can have a current gain of 100 to 400. The gain of the 2SB1140-R will be in the range from 100 to 200, for the 2SB1140-S it will be in the range from 140 to 280, for the 2SB1140-T it will be in the range from 200 to 400.Sometimes the "2S" prefix is not marked on the package - the 2SB1140 might only be marked "B1140".You can replace the 2SB1140 with the 2SB1127.
