bc303The complementary NPN transistor to the BC303 is the BC301. Replacement and Equivalent for BC303 transistor You can replace the BC303 with the 2N5323 , BC161 or BC461 .The BC303 is a bipolar junction transistor (BJT) with an PNP-type confuration. That means the BC303 transistor has a negatively charged layer between two positively charged layers. This
