umdengineer08 Posted January 19, 2005 Report Posted January 19, 2005 Can anyone help me with a suitable replacement for a a NPN transistor 2N3643? I'm trying to order parts from digikey to make a project described here but digikey has no records of a transistor of that number on their online search. Any help would be appreciated. Quote
mixos Posted January 23, 2005 Report Posted January 23, 2005 Hello umdengineer08 Suitable transistor to 2N3643 are:MPSA062N4401PN3643Hope you find one of them to finish your project :). Don't forget to tell as your expiriences building your circuit :D Quote
steven Posted February 1, 2005 Report Posted February 1, 2005 :)the 2n3643 to-105 npn is a gp amp and switch it is allso comparable tp the bc337 transister of which is comparable to the 2n3642 transister Quote
