The Molex 0511101650 is the 16-circuit receptacle housing from the Milli-Grid 51110 series, built for wire-to-board or wire-to-wire harnesses where a compact 2.00 mm pitch keeps board real estate tight.
What mates with the 0511101650?
The header pins insert into the female sockets you crimp and insert separately. No keying or polarization built into the housing — orientation is set by the header's own features.
The listing note says it plainly: contacts are not included. The 0511101650 is an empty shell. You need the matching Milli-Grid crimp terminals — Molex order codes 50394 (tin) or 50395 (gold) for 22-28 AWG wire — and a hand crimp tool. The housing accepts the female socket contacts; after crimping, they insert into the rear cavity and lock with an audible click. No secondary retainer on this generation — the terminal latch holds.
Sourcing this part
Sourced through independent distribution channels. The 16-position count and 2.00 mm pitch are the two numbers that lock the BOM line; verify the mating header order code and the crimp terminal part number before committing the full assembly.
