Here is an image showing the pin diagram of this transistor.The 2SA1013 transistor can have a current gain of 60 to 200. The gain of the 2SA1013O will be in the range from 100 to 200, for the 2SA1013R it will be in the range from 60 to 120.Sometimes the "2S" prefix is not marked on the package - the 2SA1013 might only be marked "A1013".The complementary NPN transistor to the 2SA1013 is the 2SC2383.The KST93 (SOT-23) is the SMD version of the 2SA1013 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.The KSA1013 is the TO-92 version of the 2SA1013.You can replace the 2SA1013 with the 2SA1275, KSA1013 or KTA1275.
