The BC487B 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 collector, base, and emitter leads.
Here is an image showing the pin diagram of this transistor.The BC487B transistor can have a current gain of 160 to 400. The gain of the BC487 will be in the range from 60 to 400, for the BC487A it will be in the range from 100 to 250, for the BC487L it will be in the range from 60 to 150.The complementary PNP transistor to the BC487B is the BC488B.The FMMTA05 (SOT-23), KST05 (SOT-23), MMBTA05 (SOT-23), PZTA05 (SOT-223) and SMBTA05 (SOT-23) is the SMD version of the BC487B transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the BC487B with the BC489 or BC489B.
