The single most common miss on this part: the listing note reads "Contacts Not Included." The 440129-6 housing accepts TE HPI-series female socket crimp terminals; you need to source those as a separate line item on the BOM.
Operating Temperature and Compliance
RoHS compliant per. Lifecycle status is Active — no phase-out or last-time-buy on record, so the supply channel is stable for ongoing production.
Termination is crimp, not solder or IDC, so the assembly requires a hand or automatic crimp tool and the correct terminal. Free-hanging in-line mounting means no board lock or panel feature — the housing floats on the wire harness and relies on the mating header for mechanical retention.
