Here is an image showing the pin diagram of this transistor.The 2SC594-Y transistor can have a current gain of 120 to 240. The gain of the 2SC594 will be in the range from 40 to 240, for the 2SC594-O it will be in the range from 70 to 140, for the 2SC594-R it will be in the range from 40 to 80.Sometimes the "2S" prefix is not marked on the package - the 2SC594-Y might only be marked "C594-Y".The complementary PNP transistor to the 2SC594-Y is the 2SA594-Y.The 2SC1623 (SOT-23), 2SC2412 (SOT-23), 2SC2412-Q (SOT-23), 2SC2712 (SOT-23), 2SC2712-Y (SOT-23), 2SC3803 (SOT-89), 2SC3803-Y (SOT-89), 2SC4116 (SOT-323), 2SC4116-Y (SOT-323), 2SC4738 (SOT-23), 2SC4738-Y (SOT-23), FJX945 (SOT-323), FJX945Y (SOT-323), KSC1623 (SOT-23), KTC3875 (SOT-23), KTC3875S (SOT-23), KTC3875S-Y (SOT-23), KTC3875Y (SOT-23) and TMBT3904 (SOT-23) is the SMD version of the 2SC594-Y transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC594-Y with the 2N1711, 2N3019, 2N3053A, 2N3107, 2N4032, 2N4033, 2N5321, 2N5337, 2SC108A, 2SC108A-Y, 2SC109A, 2SC109A-Y, 2SC503, 2SC503-GR, 2SC504, 2SC504-GR, BC141, BC141-16, BC300, BC300-6, BC301, BC301-6, BC302, BC302-6, BC441 or BC441-6.
