For electronic components at the level of say electrolytic capacitors, ethernet connectors connectors, and possibly in the future fiber optic connectors/electrical signal interfaces are there well established, recognized certifications that commercial spacecraft manufactures would like to see (or require) for individual components?
If for example a component fails after deployment, and someone asks "you did use all 'commercial space capacitors' didn't you?" is there a widely recognized industrial certification of some kind that can be pointed to while saying "yep, all 100% commercial space-grade electronic components!"
The background of this question is this question where I'm asking about small plastic multimode fiber connectors which would contain high speed LED or laser chips and/or photodiodes.
Since these contain a variety of both semiconductor materials and optical materials, would there be a certification process (and roadmap thereof) such that without it, a commercial spacecraft manufacturer would be hesitant to use such a component, even if it was internally validated through exhaustive testing?
There may be military and NASA grades and certifications, but I'm wondering if there are also commercial space specs, or if they just make due with other existing certification procedures.
