I appreciate the trouble you have gone to to find these items, and yes, they
would do the job. However, the Farnell Australia website (where the OP lives)
doesn't have the same stock items as in the UK, and these 2 are not included.
The Australian branch would probably order them in, but usually there is some
requirement such as MOQ or shipping added.

I spent some considerable time on the Farnell AU website tring to determine
whether or not any listed item was suitable and I have to say that their
description and part numbering and the parameter selection table leaves a lot to
be desired in trying to find a suitable item - I have complained to them on
that.

For example, I challenge you to find from the complete CNY17 listing on the
Farnell AU site
http://au.farnell.com/jsp/search/results.jsp?N=0&No=25&Ntk=gensearch_001&Ntt=cny17&Ntx=
a simple and quick method of finding a locally available substitute for the OP's
problem. Now if every DIL opto stock item had a suffix saying 300W or 400W this
would help a lot, but they don't - only some do. And it is not stated in the
stock item description either.
