It's just some work showing that the new parts are really equivalent. It also takes 12 weeks (or more) to get the evaluation parts before useful quantities can be ordered (then another 12 weeks).

I did give them some pointers about my expectations, such as "Now don't go out there and order five new MS-Office licenses just because Microsoft came out with a new version" :-) Seriously, this can happen. I had my surprise recently when arriving at a client to check out my prototype. They wanted to time a mechanical reaction initiated by my circuit and I had told them that we could do stuff like that on the cheap. A $1 piezo would have sufficed. Long story short when I arrived there was a professional sensor in hi-sheen stainless steel, cradled in a velvet-clad and immaculately polished wooden box ... -- Regards, Joerg http://www.analogconsultants.com/ "gmail" domain blocked because of excessive spam.

It's been a while but I could always get them in two weeks if needed. In a real crunch within the same week. But yeah, China tends to take longer and often the willingness to expedite drops down when the supplier grows and takes on more important (a.k.a. bigger) customers. Been there :-( -- Regards, Joerg http://www.analogconsultants.com/ "gmail" domain blocked because of excessive spam. Use another domain or send PM.

Perhaps they didn't understand the requirements and thought they needed something traceable to NIST.

Been there :-( Apparently these parts are only sourced in China, now. Even crystal oscillator lead times have slipped out that far and the disty can, under normal circumstances, program them. |
