The BC167A 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 BC167A transistor can have a current gain of 110 to 220. The gain of the BC167 will be in the range from 110 to 800, for the BC167B it will be in the range from 200 to 450, for the BC167C it will be in the range from 420 to 800.The complementary PNP transistor to the BC167A is the BC257A.The 2SC1623 (SOT-23), BC847 (SOT-23), BC847A (SOT-23), BC847AW (SOT-323), BC847W (SOT-323), BC850 (SOT-23), BC850A (SOT-23), BC850AW (SOT-323), BC850W (SOT-323) and KSC1623 (SOT-23) is the SMD version of the BC167A transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the BC167A with the 2N3416, 2SC1318, 2SC1384, 2SC1627, 2SC1627A, 2SC1815, 2SC200, 2SC2002, 2SC2003, 2SC2274, 2SC2274K, 2SC2277, 2SC2310, 2SC2458, 2SC2655, 2SC2785, 2SC2960, 2SC3114, 2SC3198, 2SC3199, 2SC3243, 2SC3328, 2SC3330, 2SC3331, 2SC3382, 2SC3383, 2SC3708, 2SC3916, 2SC3917, 2SC3918, 2SC3919, 2SC3920, 2SC3921, 2SC3922, 2SC3923, 2SC3940A, 2SC4208A, 2SC945, 2SD1207, 2SD1347, 2SD1835, 2SD438, 2SD667, 2SD789, 2SD863, BC182LB, BC635, C1815, C945, H945, KSC1008C, KSC1815, KSC2331, KSC815C, KSC945C, KSP8098C, KSP8099C, KTC1006, KTC1008, KTC200, KTC3198, KTC3199, KTC3209, KTC3227 or KTD863.
