[Free Desktop Component Search Widget]

For current production components, SupplyFrame created a cool little widget that lets you pull up crosses, specs, sources and other useful information about 2.5M components.  Avnet supplies some of the data too.

Wont help you find obsolete stuff, sorry.  But will probably save you time finding info on current stuff.

It's free.

My apologies if you interpret this as advertising - but this is a free tool designed for electronics designers.  Thought you would want to take advantage of it.

[Cool Component Search Engine: Crosses, Data Sheets, RoHS]

Sorry if you didnt find what you were looking for.  Supplyframe tracks 1.5M part numbers today and the number is growing steadily. 

However - the parts you list are discontinued.  SupplyFrame is focused in design engineers creating products. 

I know most of parts sought on this board are hard to find  / obsoletes.  Hopefully SupplyFrame can help you with the 'other' kind.

This one is just what you need.  Look up any component and get the specs, crosses, RoHS compliance, pricing and sources.
