Here is an image showing the pin diagram of this transistor.The 2SC3419-O transistor can have a current gain of 70 to 140. The gain of the 2SC3419 will be in the range from 70 to 240, for the 2SC3419-Y it will be in the range from 120 to 240.Sometimes the "2S" prefix is not marked on the package - the 2SC3419-O might only be marked "C3419-O".The complementary PNP transistor to the 2SC3419-O is the 2SA1356-O.The 2SC3325 (SOT-23), 2SC3325-O (SOT-23), 2SC3912 (SOT-23), 2SC3913 (SOT-23), 2SC3914 (SOT-23) and 2SC3915 (SOT-23) is the SMD version of the 2SC3419-O transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC3419-O with the 2N4921, 2N4921G, 2N4922, 2N4922G, 2N4923, 2N4923G, 2SC1212, 2SC1212A, 2SC496, 2SC496-O, 2SD1722, 2SD1722-Q, 2SD1723, 2SD1723-Q, 2SD414, 2SD794, 2SD794A, BD131, BD135, BD135-10, BD135G, BD137, BD137-10, BD137G, BD139, BD139-10, BD139G, BD165, BD167, BD169, BD175, BD175-10, BD177, BD177-10, BD179, BD179-10, BD179G, BD187, BD189, BD226, BD228, BD230, BD233, BD233G, BD235, BD235G, BD237, BD237G, BD375, BD375-10, BD377, BD377-10, BD379, BD379-10, BD439, BD439G, BD441, BD441G, BD785, BD787, BD787G, BD789, BDX35, BDX36, BDX37, KSD794, KSD794A, KSE180, KSE181, KSE182, KTC2814, KTC2814-O, MJE180, MJE180G, MJE181, MJE181G, MJE182, MJE182G, MJE220, MJE221, MJE222, MJE223, MJE224, MJE225, MJE240, MJE241, MJE242, MJE521, MJE521G, MJE720, MJE721 or MJE722.
