Hi

The key sentence does appear to be the last one in the email they sent. There are a lot of ways
to trip over the ROHS stuff. The guessing game contest now does turn into a “pick a part” exercise.
There are an enormous number of mistakes that somebody / somewhere in the supply chain could 
have made…

Since it appears to be CE related, I would bet it is a ROHS phase in issue. Thus they still ship to the
US, but not to Europe. So, what’s different on ROHS in the US vs Europe this week that wasn’t different say a 
year ago?

Bob
