I love Octopart and wish it would become even more wildly successful. However...<p>The problem I have with Octopart and other "better search" engines (like Hipmunk, Padmapper, et al) is that the coverage is not 100%--not every item in inventory is shown on the search engine site.<p>The lack of complete coverage kills me when I'm looking for a very specific edge case, which are exactly the sorts of cases that would most benefit from a better search experience. When I really want that one 10uF/6.3V X7R ceramic capacitor made by TDK, and I can't find it on Octopart, it renders the whole of Octopart useless.<p>Until these sorts of frontend sites get better adoption from the people who actually <i>supply the inventory</i> (e.g. Octopart -> Digikey, Hipmunk -> Expedia, Padmapper -> Craigslist), they cease to be useful in all the cases where they would provide major benefit.
