Anyone knows of a site listing all electronic housings with their dimensions ? :sad:

Thanks,

you can frequently find these in datasheets (though not always). Usually they are towards the end.

For example, a quick search turned up this datasheet http://ftp.si2.org/si2_publications/ecix/pdf/LM195.pdf
look at the end of it for a TO-3 drawing.

Here is a link with several. Just click on the package name.

Hope this helps, Dave

I don't know of one listing ALL but some come pretty close.

Most IC manufacturers have a separate datasheet or set for just packages. Search package on any semi manufacturer website

IC resellers like DigiKey have good images on the catalog pages near the parts but not necessarily better online.

Adapter makers like Emulation.com had a good list but the industry is hard to keep up with.

JEDEC.ORG is the standards body that defined the majority of packages and they have docs and data sheets on their website (registration required for free doc search)

Trade magazines like PCB design and Semiconductor packaging news occasionally list buyers guides and a packaging matrix.

The older discrete packages you listed should be easy to locate together. Add in the SMT packages and you have a whole new group.
