Here is an image showing the pin diagram of this transistor.The 2SA794-Q transistor can have a current gain of 90 to 155. The gain of the 2SA794 will be in the range from 90 to 220, for the 2SA794-R it will be in the range from 130 to 220.Sometimes the "2S" prefix is not marked on the package - the 2SA794-Q might only be marked "A794-Q".The 2SA1368 (SOT-89) and 2SA1368-D (SOT-89) is the SMD version of the 2SA794-Q transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SA794-Q with the 2SA1021, 2SA1184, 2SA1184-O, 2SA1220, 2SA1220A, 2SA1358, 2SA1358-O, 2SA1408, 2SA794A, 2SA794A-Q, 2SA795, 2SA795-Q, 2SA795A, 2SA795A-Q, 2SB1167, 2SB1168, 2SB549, 2SB631, 2SB631K, 2SB649, 2SB649A, BD792, KSA1220, KSA1220A, KTA1700, MJE253, MJE253G or MJE254.
