Most of my orders from Mouser are things that are out-of-stock at Digi-Key. Maybe this is how they lose and join the also-ran, only-for-big-companies distributors like Allied and Newark.
Huh? I'm strictly a hobbyist and I order from Newark all the time, and have never had any issues with them. If anything they are my first "go to" site to check for parts, or possibly it's a "1A / 1B" thing with them and Mouser. Nothing about my interactions with Newark have ever given me a "only for big companies" vibe, FWIW.
