BC848 NPN transistor equivalent |

John Swift:
Hi Ian , I would expect the BC107 or BC107B to be OK in fact almost any low power silicon npn transistor is likely to work take a look at the " universal npn transistors " used by Elektor magazine in their simple projects search for " TUN TUP DUS DUN " John |

Hello John the following links may be useful for future lookup http://www.datasheetcatalog.com/datasheets_pdf/B/C/8/4/BC848.shtml many other data sheets available here. Also http://talkingelectronics.com/projects/TransistorData/TransistorData-P1.html Cover a large range, if you are looking for a Japanese transistor starting C**** then add 2S in fron making 2SC**** When choosing a substitute try to match or better the characteristics. If it is for very high frequency( 10meg hertz plus) work then some times only a correct replacement will work satisfactory, but this is rare. I am sure other folk may have other opinions, but I have found this approach works for me. Trev |
John Swift:
Hi Trev , thanks for the info two usefull links while a search for data for a transistor very often links to datasheetcataloge.com the talking electronics page is one i've missed the link to philips and the smd marking data I've just downloaded until now I had no idea what a 2BJ transistor was my DCA55 component analyser is good , but it does not give part numbers!!! (its a BC849b by the way) yes you are right , japanese transistor numbers only make sence if you know they don't print the 2S prefix on the part John |
