Here is an image showing the pin diagram of this transistor.The 2SA1633-E transistor can have a current gain of 100 to 200. The gain of the 2SA1633 will be in the range from 60 to 320, for the 2SA1633-D it will be in the range from 60 to 120, for the 2SA1633-F it will be in the range from 160 to 320.Sometimes the "2S" prefix is not marked on the package - the 2SA1633-E might only be marked "A1633-E".The complementary NPN transistor to the 2SA1633-E is the 2SC4278-E.You can replace the 2SA1633-E with the 2SB1162, 2SB1162-P, 2SB1163, 2SB1163-P, MJW1302A or MJW1302AG.
