The MonoPlug 2.5 Connector System from TE can be used as a direct or indirect connector, as a card edge connector or on a printed circuit board.
If you are looking at the shape of the female receptacle socket, you may find it differs from the 3D drawing.
Confirmed by TE, there was a design improvement and the shape change was covered in this PCN: PCN-20-101127.pdf (digikey.com).
There is not much information on this change, but manufacturer stated this document covers what is known.
Here is the reference drawing from the product application specification.
