Here is an image showing the pin diagram of this transistor.The 2SB648-C transistor can have a current gain of 100 to 200. The gain of the 2SB648 will be in the range from 60 to 320, for the 2SB648-B it will be in the range from 60 to 120, for the 2SB648-D it will be in the range from 160 to 320.Sometimes the "2S" prefix is not marked on the package - the 2SB648-C might only be marked "B648-C".The complementary NPN transistor to the 2SB648-C is the 2SD668-C.You can replace the 2SB648-C with the 2SA1021, 2SA1021-O, 2SA1142, 2SA1142Q, 2SA1144, 2SA1184, 2SA1209, 2SA1209-R, 2SA1210, 2SA1210-R, 2SA1220, 2SA1220-Q, 2SA1220A, 2SA1220A-Q, 2SA1248, 2SA1248-R, 2SA1249, 2SA1249-R, 2SA1352, 2SA1352-E, 2SA1358, 2SA1360, 2SA1380, 2SA1380-E, 2SA1404, 2SA1404-E, 2SA1405, 2SA1405-E, 2SA1406, 2SA1406-E, 2SA1407, 2SA1407-E, 2SA1408, 2SA1408-O, 2SA1477, 2SA1477-R, 2SA1478, 2SA1478-E, 2SA1507, 2SA1507-R, 2SA1538, 2SA1538-E, 2SA1539, 2SA1539-E, 2SA1540, 2SA1540-E, 2SA1541, 2SA1541-E, 2SA794A, 2SA795, 2SA795A, 2SA914, 2SB1109, 2SB1109-C, 2SB1110, 2SB1110-C, 2SB631K, 2SB631K-E, 2SB648A, 2SB648A-C, 2SB649, 2SB649-C, 2SB649A, 2SB649A-C, HSB1109, HSB1109-C, KSA1142, KSA1142O, KSA1220, KSA1220-O, KSA1220A, KSA1220A-O, KTA1700, KTA1704 or KTA1704-Y.
