Here is an image showing the pin diagram of this transistor.The 2SC1953-R transistor can have a current gain of 130 to 220. The gain of the 2SC1953 will be in the range from 130 to 330, for the 2SC1953-S it will be in the range from 185 to 330.Sometimes the "2S" prefix is not marked on the package - the 2SC1953-R might only be marked "C1953-R".The complementary PNP transistor to the 2SC1953-R is the 2SA914-R.You can replace the 2SC1953-R with the 2N5655, 2N5655G, 2N5656, 2N5656G, 2SC1565, 2SC1565-R, 2SC1565A, 2SC1565A-R, 2SC2258, 2SC2481, 2SC2682, 2SC2688, 2SC2690A, 2SC2704, 2SC2704-Y, 2SC2911, 2SC2912, 2SC3116, 2SC3117, 2SC3335, 2SC3416, 2SC3417, 2SC3423, 2SC3423-Y, 2SC3502, 2SC3503, 2SC3600, 2SC3601, 2SC3787, 2SC3788, 2SC3789, 2SC3790, 2SC3902, 2SC3955, 2SC3956, 2SC4212, 2SD1609, 2SD1610, BD127, BD128, BD157, BD158, HSD1609, KSC2258, KSC2258A, KSC2682, KSC2688, KSC2690A, KSC3502, KSC3503, KSE340, KTC2800, KTC2800-Y, MJE340, MJE340G, MJE344 or MJE344G.
