Here is an image showing the pin diagram of this transistor.The 2SA1693-O transistor can have a current gain of 50 to 100. The gain of the 2SA1693 will be in the range from 50 to 180, for the 2SA1693-P it will be in the range from 70 to 140, for the 2SA1693-Y it will be in the range from 90 to 180.Sometimes the "2S" prefix is not marked on the package - the 2SA1693-O might only be marked "A1693-O".The complementary NPN transistor to the 2SA1693-O is the 2SC4466-O.The BDP952 (SOT-223) is the SMD version of the 2SA1693-O transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SA1693-O with the 2SA1102, 2SA1103, 2SA1104, 2SA1105, 2SA1106, 2SA1186, 2SA1186-O, 2SA1303, 2SA1303-O, 2SA1386, 2SA1386-O, 2SA1489, 2SA1489-O, 2SA1490, 2SA1490-O, 2SA1491, 2SA1491-O, 2SA1694, 2SA1694-O, 2SA1695, 2SA1695-O, 2SB1230, 2SB1230-P, 2SB1231, 2SB1231-P, 2SB1232, 2SB1232-P, 2SB695, BD246B, BD246C, BD250B, BD250C, BD746B, BD746C, BDV94, BDV96, FJA4210, FJA4210R, MJW21191, MJW21191G, NTE391, TIP34B, TIP34C or TIP36CA.
