We got a PCN from Panasonic dated Sept 1, 2025 for “Part of ECQE/ECWF/ECQWH series” indicating a “Change of Film Capacitor Outer resin ”.
While we don’t expect this change impacts function or performance, the notification does not state that explicitly.
Could you please confirm?
Thanks!
Greetings,
The product can be expected to meet/exceed the applicable functional and performance specifications in effect at the time of manufacture.
While unlikely to impact primary electrical characteristics, there are differences that a person may or may not care about for a given application. It’s not within a manufacturer’s abilities to guarantee that all users will be indifferent to such differences, so rather than making statements to such effect the typical practice is simply to provide courteous notice of a change occurring, and leave it up to the user to decide whether or not it matters for their purposes.
Thanks rick_1976.
I’m just used to PCN’s stating that there is no impact to form/fit/function, or compliance to datasheet/specifications. That type of statement was missing. Understood that there might be additional characteristics that certain users might be concerned with, but compliance to a datasheet should get stated with such change notifications.
It’s not uncommon for change notices to be issued regarding things ancillary to a product’s actual function or composition, such as a change in a manufacturing location, packaging, top marking, etc. It’s perfectly reasonable to say that there’s no expected impact to a part’s form/fit/function if the only thing that’s changing is the font used on the the box it comes in, for example.
While there’s some nuance as to what portion of a datasheet constitutes a product specification, conformity to such is a thing that’s generally assumed in functional economies because economies cease to function when people misrepresent items of trade.
As for non-functional economies or circumstances where one’s buying from parties beyond the reach of one’s legal means, statements or certificates of conformity may be worth only the paper they’re written on, which says a lot in an era of electronic documents.
