The 2SA1207-S 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 2SA1207-S transistor can have a current gain of 140 to 280. The gain of the 2SA1207 will be in the range from 100 to 400, for the 2SA1207-R it will be in the range from 100 to 200, for the 2SA1207-T it will be in the range from 200 to 400.Sometimes the "2S" prefix is not marked on the package - the 2SA1207-S might only be marked "A1207-S".The complementary NPN transistor to the 2SA1207-S is the 2SC2909-S.You can replace the 2SA1207-S with the 2SA1208, 2SA1208-S, 2SA1275, 2SA1319, 2SA1319-S, 2SA1370, 2SA1371, 2SA1376, 2SA1376A, 2SA1624, HSB1109S, KSA1013, KTA1275 or KTA1279.
