Here is an image showing the pin diagram of this transistor.The 2SC1573-R transistor can have a current gain of 100 to 220. The gain of the 2SC1573 will be in the range from 60 to 220, for the 2SC1573-Q it will be in the range from 60 to 150.Sometimes the "2S" prefix is not marked on the package - the 2SC1573-R might only be marked "C1573-R".The complementary PNP transistor to the 2SC1573-R is the 2SA879-R.The BF622 (SOT-89) and BF822 (SOT-23) is the SMD version of the 2SC1573-R transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC1573-R with the 2SC1473, 2SC1473A, 2SC1473AR, 2SC1473R, 2SC1573A, 2SC1573A-R, 2SC1573B, 2SC1573B-R, 2SC3467, 2SC3468, 2SC3941, 2SC3941-R, KSC1506 or KSC2330.
