Here is an image showing the pin diagram of this transistor.The KTC2814-O transistor can have a current gain of 70 to 140. The gain of the KTC2814 will be in the range from 70 to 240, for the KTC2814-Y it will be in the range from 120 to 240.The complementary PNP transistor to the KTC2814-O is the KTA1715-O.The 2SC2873 (SOT-89), 2SC2873-O (SOT-89), 2SC3444 (SOT-89), BCP55 (SOT-223), BCP55-10 (SOT-223), BCX55 (SOT-89) and BCX55-10 (SOT-89) is the SMD version of the KTC2814-O transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the KTC2814-O with the 2N4922, 2N4922G, 2N4923, 2N4923G, 2SD1722, 2SD1722-Q, 2SD1723, 2SD1723-Q, 2SD1724, 2SD1724-Q, 2SD1725, 2SD1725-Q, 2SD794A, BD177, BD177-10, BD179, BD179-10, BD179G, BD189, BD235, BD235G, BD237, BD237G, BD377, BD377-10, BD379, BD379-10, BD439, BD439G, BD441, BD441G, BD787, BD787G, BD789, BD791, BDX35, BDX36, BDX37, KSD794A, KSE181, KSE182, MJE181, MJE181G, MJE182, MJE182G, MJE223, MJE224, MJE225, MJE240, MJE241, MJE242, MJE243, MJE243G or MJE244.
