What This Connector Is and Where It Fits
The TE Connectivity 1-2271457-6 is a 6-position, single-row plug header from the Dynamic D-3950 series, designed for board-to-cable/wire power interconnects. It carries a 7.50mm mating pitch — wide enough to support the 600VAC rating with adequate creepage — and is rated 14.5A per circuit, placing it firmly in the power distribution class rather than signal duty. The right-angle through-hole orientation routes the cable exit parallel to the board, which suits enclosed assemblies where z-height is constrained. Gold plating on the mating side of the rectangular tab contacts handles repeated mate cycles in field-service environments, while the tin-plated solder tails keep the board-level connection cost-effective.
Key Features That Drive the Fit
The shrouded 4-wall housing with a latch holder provides positive retention — the latch engages audibly on mating and resists vibration loosening in industrial machinery or telecom racks. A board lock on the through-hole tails holds the header in place during wave soldering and takes the shear force from cable strain off the solder joints. The thermoplastic insulation carries a UL94 V-0 flammability rating, which is required for equipment installed inside enclosures without separate fire containment. Operating temperature spans -30°C to 105°C, covering unheated industrial cabinets and outdoor telecom shelters.
Mating and Termination
This is the plug (pin) side of the Dynamic D-3950 board-to-wire interface. It mates with the corresponding receptacle housing that accepts crimp terminals — the exact mating half order code depends on the circuit count and wire gauge required. Termination is through-hole solder, so the board footprint needs plated through-holes at the 7.50mm pitch. The single-row layout keeps the board footprint narrow, which helps when routing traces to a single power plane or relay bank.
Sourcing and Lifecycle
The 1-2271457-6 carries an Active lifecycle status from TE Connectivity — no end-of-life notice on record. It ships in tray packaging, which suits medium-volume assembly but means the pick-and-place line will need a tray feeder or tube adapter rather than a tape reel.
