What this housing is — and what it isn't
The 3.68mm pitch and 0.145" row spacing give it a wider footprint than a standard 2.54mm header, which buys you more creepage between circuits at the board edge.

TE Connectivity Commercial.062" Pin and Socket receptacle housing, 770356-1, 6 positions, 2 rows, 3.68mm pitch, free-hanging in-line, locking ramp, natural nylon, crimp termination, -55°C to 105°C, contacts not included.

No — the listing explicitly notes Contacts Not Included. The 770356-1 is the receptacle housing only; you order the matching crimp terminals separately from the TE Commercial.062" Pin and Socket contact family.
The pitch is 0.145" (3.68mm) between positions, with the same 0.145" row spacing. That's wider than a standard 2.54mm header, so the mating header must match this 3.68mm pitch for the locking ramp to engage.
