I've been searching for a set of headers and connectors as defined in the USB 3.0 Internal Connector and Cable Specification document for a casemod project.

Unfortunately, after scouring Digi-Key and a few manufacturer websites I can't seem to find any products actually advertised as suitable for this application.

Every other connector I've found so far is somewhat off in size and keying that I must be missing something in my search.

Is there such a thing as a USB 3.0 header or do I just need to keep comparing datasheets till I find something that makes sense?

  • \$\begingroup\$ Thanks Tony, it looks like this header is a little small compared to the standard (5mm vs 5.4 mm) which makes me think it might not accept a compliant plug without a lot of force. The search continues. \$\endgroup\$

Yep, this is a tough question. The body of plug (wire side) has 5.2 mm width, and length of 20.65 mm. None of Molex-Amphenol-etc products match it.

The connector seems to be solely manufactured by Foxconn, an old Intel ally and platform manufacturing house. There are some re-sellers like ModDIY.

Or see this e-Bay listing if you need few parts.


I know this conversation is quite old, but I found it while looking for the same thing.

And since I found a valid answer elsewhere, I put it here so anyone can enjoy the information:

Amphenol G823J201240BHR is advertised as a compatible part
