Dear Experts
For repairing an audio power amp I need a pair of BD311N/BD312N.
Unfortunately I've found just technical data for BD311/312. Can anybody tell me the difference between BD311/312 and BD311N/312N?
TIA
Reinhard

Generally , but presumably manufacturer dependent Transistor number with an N suffix = lead free / RoHS pins/leads. ie full tin coating, so scrape back for tin-pest free, long term reliability, if soldering into old kit.

Hello
Thank you very much for answering.
AFAIK those transistors were produced in the 70s of the last century: ROHS wasn't on topic at that time ...
Best regards
Reinhard
