Product details

7.40 mm pitch, 3-position right-angle header

This is a Molex MultiCat 201843 series header, order code 2018431031. It is a Board to Cable/Wire style connector with 3 positions in a single row, spaced at 0.291" (7.40 mm) pitch.

1200 V, latch lock, PEI housing

Rated 1200 V, this header is designed for high-voltage power interconnect rather than signal-level duty. The latch lock fastening type secures the mating cable connector against vibration-induced disconnection. The insulation is polyetherimide (PEI) rated UL94 V-0, providing a continuous operating temperature range of -40°C to 150°C — above typical PBT limits. Mating contact finish is gold (3.90 µin), with tin on the solder posts. The gold mating surface supports repeated mate/unmate cycles without oxidation.

Lifecycle status is Active with no end-of-life notice. The part is ROHS3 compliant.
