The 316090-1 is a 6-position, single-row receptacle housing from TE's Signal Double Lock series, on 2.50mm pitch. The housing accepts the terminal and locks it in place; if it backs out, it's scrap.
Mates with a Signal Double Lock header that has 0.098" (2.50mm) pitch, 6 circuits, 1 row, tab contacts. The latch holder on this receptacle clicks onto the header's locking ramp. The housing is keyed so the terminal can't go in wrong.
