The 0436400410: The housing is a shell — it ships empty, so the crimp terminals are ordered separately. Glow Wire Compliant per IEC 60335-1 means the housing plastic won't sustain a flame from a hot wire fault — a requirement for household appliances and commercial kitchen equipment. The single-row 4-position layout keeps the footprint narrow, useful for tight harness routing near a board edge.
This plug housing mates with any Micro-Fit 3.0 header of the same 3.00mm pitch and 4-circuit count — the 43645 series vertical headers or the 43650 right-angle headers. The locking ramp engages the header's latch pocket; you'll hear the click when fully seated. The crimp terminals that load into this housing are the Molex 43030 series male pins for 20-24 AWG wire. The terminal insertion tool (Molex 63811-7900) and extraction tool (Molex 63811-8000) are also separate purchases for field repair.
