The BC488B 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 BC488B transistor can have a current gain of 160 to 400. The gain of the BC488 will be in the range from 60 to 400, for the BC488A it will be in the range from 100 to 250, for the BC488L it will be in the range from 60 to 150.The complementary NPN transistor to the BC488B is the BC487B.The FMMTA55 (SOT-23), KST55 (SOT-23), MMBT4354 (SOT-23), MMBT4355 (SOT-23), MMBTA55 (SOT-23), PZTA55 (SOT-223) and SMBTA55 (SOT-23) is the SMD version of the BC488B transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the BC488B with the BC490 or BC490B.
