Nearly all the industry is moving to those connectors. They work well
and last as long as "real connectors", but they are not designed for
soldering manually. I recently needed some mini DINs, I found the
Apple printer cords available in various lengths on close out. I cut
them to length and ended up with two good cables out of each one
purchased. I soldered regular DINs on the open ends. Those mini DINs?
Yup, they were the one's with the low temperature plastic dielectric.
Fortunately I didn't have to solder to any of those.
My fear is that as industry moves to the machine assembled (and
soldered) idiotic ROHS connectors, the need for those so called "real
connectors" is likely to drop to the point where they will no longer be
made. Like "real solder" will be difficult and eventually impossible to
purchase, it's likely "real connectors" will go the same route. I'm
speaking of the mini DIN as opposed to the cheaply constructed UHF and N
connectors.
