Here is an image showing the pin diagram of this transistor.The 2SC504-O transistor can have a current gain of 50 to 150. The gain of the 2SC504 will be in the range from 30 to 300, for the 2SC504-GR it will be in the range from 100 to 300, for the 2SC504-R it will be in the range from 30 to 90.Sometimes the "2S" prefix is not marked on the package - the 2SC504-O might only be marked "C504-O".The complementary PNP transistor to the 2SC504-O is the 2SA504-O.You can replace the 2SC504-O with the 2N3053A, 2N4238, 2N4239, 2N5320, 2N5321, 2N5334, 2N5335, 2N5681, 2N5682, 2SC108A, 2SC503, 2SC503-O, 2SC510, 2SC510-O, 2SC512, 2SC512-O, BC141 or BC441.
