The 2SA904-G 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,
Here is an image showing the pin diagram of this transistor.The 2SA904-G transistor can have a current gain of 400 to 800. The gain of the 2SA904 will be in the range from 250 to 1200, for the 2SA904-F it will be in the range from 250 to 500, for the 2SA904-H it will be in the range from 600 to 1200.Sometimes the "2S" prefix is not marked on the package - the 2SA904-G might only be marked "A904-G".You can replace the 2SA904-G with the 2SA904A or 2SA904A-G.
