The 2SC1473AQ 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, the emitter, collector, and base leads.
Here is an image showing the pin diagram of this transistor.The 2SC1473AQ transistor can have a current gain of 60 to 150. The gain of the 2SC1473A will be in the range from 30 to 220, for the 2SC1473AP it will be in the range from 30 to 100, for the 2SC1473AR it will be in the range from 100 to 220.Sometimes the "2S" prefix is not marked on the package - the 2SC1473AQ might only be marked "C1473AQ".The complementary PNP transistor to the 2SC1473AQ is the 2SA1767Q.The BF620 (SOT-89) and BF820 (SOT-23) is the SMD version of the 2SC1473AQ transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC1473AQ with the 2N6517C, 2SC1573A, 2SC1573A-Q, 2SC1573B, 2SC1573B-Q, 2SC2271, 2SC2482, 2SC2551, 2SC2551-O, 2SC3468, 2SC3941, 2SC3941-Q, KSC1506 or KSC2330.
