What the Ratings Mean for the Fit
The 444411003: Side-to-side stacking direction means multiple housings can gang along the same axis — useful when circuit count grows and you need a uniform harness profile rather than a multi-row footprint.
Mating and Termination
This is a receptacle housing only — the female blade socket is the contact it accepts, not the form factor it presents to the mated header. The mating half (typically a plug or male blade header in the same Sabre series) must match the 3-position count and latch geometry. Crimp termination gives field-serviceability; ensure the wire strip length and crimp tool setting match the terminal supplier's data sheet for the pull-force rating.
