Here is an image showing the pin diagram of this transistor.The 2SC1846S transistor can have a current gain of 170 to 340. The gain of the 2SC1846 will be in the range from 85 to 340, for the 2SC1846Q it will be in the range from 85 to 170, for the 2SC1846R it will be in the range from 120 to 240.Sometimes the "2S" prefix is not marked on the package - the 2SC1846S might only be marked "C1846S".The complementary PNP transistor to the 2SC1846S is the 2SA885S.You can replace the 2SC1846S with the 2SC2270, 2SC3420, 2SD1348, 2SD1682, 2SD1683, 2SD1722, 2SD1723, 2SD809, BD131, BD165, BD167, BD187, BD189, BD233, BD233G, BD235, BD235G, BD375, BD375-25, BD377, BD377-25, BDX35, BDX36, MJE222, MJE225, MJE521, MJE521G, MJE720 or MJE721.
