Dear all,
for a propotype I am working on my customer asked me to use a TO-3 package.

I am having trouble to find where to buy those old faschion package (for my optoelectronic application).

Does aneybody has any hint, suggestion, advice on where I can buy 100 of those packages?

Many thanks in advance

If it's a transistor, Digikey has seems to have plenty: https://www.digikey.com/en/products/filter/transistors-bipolar-bjt-single/276?s=N4IgjCBcpgTAnBaIDGUBmBDANgZwKYA0IA9lANogAsYAzAKzy0gC6xADgC5QgDKnAJwCWAOwDmIAL6TisCiEGYRuIZxIDcrSUA

Of course, the prices may be quite high, but if your "customer" insists, presumably it is willing to pay.

You can cannibalize an old transistor.

Gyro:
If you search for 'Hermetic Packages' on the web, you will get more hits, eg.  http://www.platronics-seals.com/product/to-3-header/

Hopefully you can find a company that is a bit more local.

It's ok to push back when a customer makes an unreasonable request.  Explain to them the TO3 package is long ago obsolete and is very inefficient anyway. 

Do you have any idea why they like a TO3 package?  Why would they care?  Are you building an entire circuit in this package because the customer has a design with a TO3 package in it and your design will replace the existing part?
