Here is an image showing the pin diagram of this transistor.The 2SA1184-O transistor can have a current gain of 80 to 160. The gain of the 2SA1184 will be in the range from 80 to 240, for the 2SA1184-Y it will be in the range from 120 to 240.Sometimes the "2S" prefix is not marked on the package - the 2SA1184-O might only be marked "A1184-O".The complementary NPN transistor to the 2SA1184-O is the 2SC2824-O.The 2N5401S (SOT-23), DXT5401 (SOT-89), DZT5401 (SOT-223), FMMT555 (SOT-23), KST5401 (SOT-23) and MMBT5401 (SOT-23) is the SMD version of the 2SA1184-O transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SA1184-O with the 2SA1021, 2SA1220, 2SA1220A, 2SA1358, 2SA1358-O, 2SA1408, 2SA795, 2SA795A, 2SB631K, 2SB649, 2SB649A, KSA1220, KSA1220A or KTA1700.
