Here is an image showing the pin diagram of this transistor.The 2SC4466-O transistor can have a current gain of 50 to 100. The gain of the 2SC4466 will be in the range from 50 to 180, for the 2SC4466-P it will be in the range from 70 to 140, for the 2SC4466-Y it will be in the range from 90 to 180.Sometimes the "2S" prefix is not marked on the package - the 2SC4466-O might only be marked "C4466-O".The complementary PNP transistor to the 2SC4466-O is the 2SA1693-O.The BDP951 (SOT-223) is the SMD version of the 2SC4466-O transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC4466-O with the 2SC2577, 2SC2578, 2SC2579, 2SC2580, 2SC2581, 2SC2837, 2SC2837-O, 2SC3284, 2SC3284-O, 2SC3519, 2SC3519-O, 2SC3853, 2SC3853-O, 2SC3854, 2SC3854-O, 2SC3855, 2SC3855-O, 2SC4467, 2SC4467-O, 2SC4468, 2SC4468-O, 2SD1840, 2SD1840-P, 2SD1841, 2SD1841-P, 2SD1842, 2SD1842-P, 2SD731, BD245B, BD245C, BD249B, BD249C, BD745B, BD745C, BDV93, BDV95, FJA4310, FJA4310R, MJW21192, MJW21192G, NTE390, TIP33B, TIP33C or TIP35CA.
