The Molex 0436451100 is an 11-circuit Micro-Fit 3.0 receptacle housing — the wire-side half of the wire-to-board interconnect system.
Contacts Not Included — What You Actually Order
This is a housing only. You need to order the matching Micro-Fit 3.0 female crimp terminals separately — typically the Molex 430300001 (for 20-24 AWG) or 430300007 (for 18-24 AWG), depending on your wire gauge. The 11-position count is less common than the even-numbered variants — it matches a specific circuit count on a BOM, not a standard 2/4/6/8/10/12 pattern. If your wire bundle has exactly 11 conductors, this is the housing.
This receptacle mates with a Micro-Fit 3.0 male header — typically a vertical or right-angle through-hole header in the same 43645 series or the 43045 series. The 11-circuit receptacle requires an 11-circuit header; the keying is built into the housing geometry to prevent mis-mating with different-position housings.
