About TX1 module ‘s Connector

Hi,
Now I’m design the TX1’s hardware,I download the Carrier Board BOM,and know the TX1 module’s Connector is Manufacture by Samtech,and it’s part number is REF-186138-02,But I can’t query the product in Samtech.So Where can I buy the Connector? Can’t I buy it from Samtech?

Please refer to this topic: https://devtalk.nvidia.com/default/topic/894945/jetson-tx1/?offset=79

The P/N is SEAM-50-02.0-S-08-2-A-K-TR

So :

REF-186138-02 = SEAM-50-02.0-S-08-2-A-K-TR

Right!!!
