Quoted from Euchrid:So why does Clay's guide list MJE340 as the transistor at Q1, but Great Plains has it as MJE 15030? And is MJE 15030 the same as MJE15030G? Most places don't have 15030, but they do sell the 15030G.
Thanks!
I know... old post. But to answer the question that nobody else answered and for future reference:
MJE15030 and MJE15030G are essentially the same part. The MJE15030G is RoHS compliant (no lead used in part) whereas the MJE15030 is not RoHS compliant (contains lead).
