Here is an image showing the pin diagram of this transistor.The 2SC1568-Q transistor can have a current gain of 90 to 155. The gain of the 2SC1568 will be in the range from 90 to 280, for the 2SC1568-R it will be in the range from 130 to 210, for the 2SC1568-S it will be in the range from 180 to 280.Sometimes the "2S" prefix is not marked on the package - the 2SC1568-Q might only be marked "C1568-Q".The complementary PNP transistor to the 2SC1568-Q is the 2SA900-Q.You can replace the 2SC1568-Q with the 2SC1162, 2SC1368, 2SC1846, 2SC1846Q, 2SC495, 2SD1380, 2SD1380-P, 2SD1681, 2SD439, 2SD793, 2SD882, BD185, KSD882, KSE200, KSH882, KTC2804, MJE200, MJE200G or MJE520.
