Locating parts

[gmaslin]

I am looking for a search engine by spec. the idea is to find parts by specific parameters. I know some manufacturers have this for their own products but has anyone found one that is vendor agnostic? For example, I need a short list of complimentary bipolars with hFe>500. Where do I get this?

I am by no means an expert in the EE field, but, I've found Mouser and Digi-Key to have great parts filters.  I prefer Mouser, but that's my own preference.  I do use Digi-Key as a second source.

Thanks guys. How successful am I likely to be asking for a matched set in the wanted section?

Dearest Wilfred, that was the ticket, thanks!
