thefRont Posted October 27, 2005 Report Share Posted October 27, 2005 Hi,I've just received all my parts necessary to build a midibox sid.but one question remains. although I have ordered the BC 547A Transistor which is needed for the AOUT Module, I received a BC 547C. Is there any difference between those two or can I safely put the BC 547C on the Board?CyaDaniel Quote Link to comment Share on other sites More sharing options...
moebius Posted October 27, 2005 Report Share Posted October 27, 2005 Hi.There is difference (probably hfe) between these devices, but it doesn't have any significance here.Bye, Moebius Quote Link to comment Share on other sites More sharing options...
pay_c Posted October 27, 2005 Report Share Posted October 27, 2005 The difference of the letter is the gain. A´s do have a little less gain than B or C transistor types. But in 99% of all cases that does not matter at all. Especially not in *superbly designed* Midiboxes. ;) ;D Quote Link to comment Share on other sites More sharing options...
thefRont Posted October 27, 2005 Author Report Share Posted October 27, 2005 thanx for your replies.so that means I don't have to send the transistors back to replace them with BC 547A.cyadaniel Quote Link to comment Share on other sites More sharing options...
Fx3_hdrive Posted November 4, 2005 Report Share Posted November 4, 2005 the letter at the end notates the manufacturer of the transistor, as mobeus said hfe might be slightly different. nothing to worry about as long as the base number is correct "BC 547" even if the number after is like BC 547-25, BC547-50 etc...etc...hope this helps Quote Link to comment Share on other sites More sharing options...
