I am trying to find the male end of the connectors found on many modern computer motherboards which are used to connect USB 3.0 from a case to the motherboard. These have 2 rows of 10 positions (so 20 positions) but with only 19 pins (corner one missing). The plastic walls around the set of 19 pins are keyed too.
Searching on the TE website and digikey and others pretty much always gives either 20 pin connectors with all pins present, or 19 pins but the pins offset from each other. I can find many such connectors on stores like Amazon, alibaba, ebay, etc, but we need a higher volume from a reputable distributer like digikey. We also have high enough volume that we can't just modify existing ones we find on eBay via simply snipping the pin.
Is there a terminology issue? A term I often find is "19 pin 20 pin" and "idc", but they aren't giving me anything close to a specific part with a part number from te connectivity or digikey or mouser or similar.
