The KTC3194Y 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 KTC3194Y transistor can have a current gain of 120 to 200. The gain of the KTC3194 will be in the range from 40 to 200, for the KTC3194O it will be in the range from 70 to 140, for the KTC3194R it will be in the range from 40 to 80.You can replace the KTC3194Y with the 2N3416, 2N3704, 2N3707, 2N3708, 2N3710, 2SC1318, 2SC1318-R, 2SC1384, 2SC1384-R, 2SC1815, 2SC1815Y, 2SC1959, 2SC1959-Y, 2SC200, 2SC200-Y, 2SC2002, 2SC2120, 2SC2120-O, 2SC2236, 2SC2236-O, 2SC2274, 2SC2274-E, 2SC2277, 2SC2277C, 2SC2310, 2SC2310-B, 2SC2328A, 2SC2328A-O, 2SC2458, 2SC2458-Y, 2SC2655, 2SC2655Y, 2SC2710, 2SC2710-O, 2SC2785, 2SC2960, 2SC2960-E, 2SC3114, 2SC3114-R, 2SC3198, 2SC3198-Y, 2SC3199, 2SC3199-Y, 2SC3202, 2SC3202-Y, 2SC3203, 2SC3203-O, 2SC3205, 2SC3205-O, 2SC3243, 2SC3330, 2SC3330-R, 2SC3331, 2SC3331-R, 2SC3382, 2SC3382-R, 2SC3383, 2SC3383-R, 2SC3916, 2SC3917, 2SC3918, 2SC3919, 2SC3920, 2SC3921, 2SC3922, 2SC3923, 2SC3940A, 2SC3940A-R, 2SC4208A, 2SC4208A-R, 2SC4408, 2SC458, 2SC458-B, 2SC460, 2SC460C, 2SC461, 2SC461C, 2SC536, 2SC536-E, 2SC945, 2SD1207, 2SD1207-R, 2SD1347, 2SD1347R, 2SD1835, 2SD1835-R, 2SD789, 2SD789-B, 2SD863, 2SD863-E, BC167, BC167A, BC182L, BC182LB, BC635, C1815, C1815Y, C945, C945Y, H945, KSC1008C, KSC1008CY, KSC1815, KSC1815Y, KSC2328A, KSC2328A-O, KSC2331, KSC2331Y, KSC815C, KSC815CY, KSC945C, KSC945CY, KSD1021, KSD1021-Y, KSD471AC, KSD471ACY, KSP8098C, KTC1008, KTC1008-Y, KTC200, KTC200-Y, KTC3192, KTC3192Y, KTC3198, KTC3198Y, KTC3199, KTC3199Y, KTC3202, KTC3202Y, KTC3203, KTC3203O, KTC3204, KTC3204O, KTC3205, KTC3205O, KTC3209, KTC3209Y, KTC3210, KTC3210O, KTD863, KTD863-Y or PN3643.
