Alternates for the complementary transistors 2SC4029 & 2SC1553

The 2SC4029 “NPN” & 2SC1553 “PNP” are not currently in our system. Here are two possible complementary options, Toshiba Semiconductor and Storage #'s 2SC5200N(S1,E,S) “NPN” and and 2SA1943N(S1,E,S) “PNP” to review. Please make sure to review the specs to reassure these will work in the application.



The TechForum Cross Reference category is for parts that Digi-Key does not sell or parts that have gone obsolete. Our Engineers and Techs have reviewed the specifications for these parts and made a recommendation for a replacement. Please review the suggested part to ensure it will work for your application.
