The 2SA1029B is manufactured in a plastic TO-92 case. When looking at the flat side with the leads pointed downward, the three leads emerging from the transistor are, from left to right,
Here is an image showing the pin diagram of this transistor.The 2SA1029B transistor can have a current gain of 100 to 200. The gain of the 2SA1029 will be in the range from 100 to 500, for the 2SA1029C it will be in the range from 160 to 320, for the 2SA1029D it will be in the range from 250 to 500.Sometimes the "2S" prefix is not marked on the package - the 2SA1029B might only be marked "A1029B".You can replace the 2SA1029B with the 2SA1030 or 2SA1030B.
