Here is an image showing the pin diagram of this transistor.The 2SC1622A transistor can have a current gain of 135 to 900. The gain of the 2SC1622A-D15 will be in the range from 135 to 270, for the 2SC1622A-D16 it will be in the range from 200 to 400, for the 2SC1622A-D17 it will be in the range from 300 to 600, for the 2SC1622A-D18 it will be in the range from 450 to 900.Sometimes the "2S" prefix is not marked on the package - the 2SC1622A might only be marked "C1622A".You can replace the 2SC1622A with the FMMT624, FMMT625, KST43 or PBHV8115T.
