Here is an image showing the pin diagram of this transistor.The 2SA928A transistor can have a current gain of 100 to 320. The gain of the 2SA928A-O will be in the range from 100 to 200, for the 2SA928A-Y it will be in the range from 160 to 320.Sometimes the "2S" prefix is not marked on the package - the 2SA928A might only be marked "A928A".The complementary NPN transistor to the 2SA928A is the 2SC2328A.The 2SA1203 (SOT-89), FMMT549 (SOT-23) and KTA1663 (SOT-89) is the SMD version of the 2SA928A transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.The KSA928A is the TO-92 version of the 2SA928A.You can replace the 2SA928A with the 2SA1273, 2SB1229, 2SB892, 2SB985, KSA928A, KTA1273, KTA1282 or STB1277.
