The 2SA1624-F 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 2SA1624-F transistor can have a current gain of 160 to 320. The gain of the 2SA1624 will be in the range from 60 to 320, for the 2SA1624-D it will be in the range from 60 to 120, for the 2SA1624-E it will be in the range from 100 to 200.Sometimes the "2S" prefix is not marked on the package - the 2SA1624-F might only be marked "A1624-F".The BF621 (SOT-89), BF821 (SOT-23) and PMBTA92 (SOT-23) is the SMD version of the 2SA1624-F transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SA1624-F with the 2SA1371, 2SA1371-F, 2SA1972 or KTA1279.
