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