Hej Sven,
Thanks for sharing your experience.??My only update is that I managed to obtain the needed components.? We have 3 units with this particular failure mechanism (out of roughly 10 total).? We have a special soldering department which hopefully can get these mounted effectively.? There is a warning on the package that they should not be warmed to above 260C to avoid damage.? It's mighty hard to do that and melt solder, but with a little luck we will have these units working again within the week.? From my perspective, this is one of the two most common failure mechanisms with these units.? These units were probably kept running in a lab for multiple years and under these conditions this part just seems to fail.
