The 2SC1775-E 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 2SC1775-E transistor can have a current gain of 400 to 800. The gain of the 2SC1775 will be in the range from 400 to 1200, for the 2SC1775-F it will be in the range from 600 to 1200.Sometimes the "2S" prefix is not marked on the package - the 2SC1775-E might only be marked "C1775-E".The complementary PNP transistor to the 2SC1775-E is the 2SA872-E.You can replace the 2SC1775-E with the 2SC1775A, 2SC1775A-E, 2SC1841, 2SC1841E, 2SC1845, 2SC1845E, 2SC1890, 2SC1890-E, 2SC1890A, 2SC1890A-E, 2SC2326, 2SC2326K, 2SC2543, 2SC2543-E, 2SC2544, 2SC2544-E, 2SC2546, 2SC2546-E, 2SC2547, 2SC2547-E, 2SC2784, 2SC2784-E, 2SC3245, 2SC3245-G, 2SC3245A, 2SD755, 2SD755-E, 2SD756, 2SD756-E, KSC1845 or KSC1845E.
