IMP003 availability at Digikey

At digikey I see two types of IMP003s. One has the extensions TEMP in the Manufacturer Part Number and the other is not available. What does TEMP mean? Can I use it normally?

I believe the TEMP ones were early samples which were not production qualified (ie they were made before thermal cycling was complete: they didn’t change the design when it was complete, so they should be identical, but technically they were made pre-qual).

You can use them normally but… they’re not production qualified.
