The 1744429-3: This is a 3-position single-row header from TE's Economy Power series, pitched at 0.156" (3.96 mm) — the standard spacing for wire-to-board power and signal connections in industrial and lighting gear.
Insulation height of 0.127" (3.22 mm) keeps the shroud low above the board surface.
The pitch is 0.156" (3.96 mm) and the current rating is 7.5 A per contact at 250 VAC.
Yes, it is ROHS3 compliant and glow wire compliant, with a UL94 V-0 flammability rating on the nylon housing.
It mates with a standard 3.96 mm pitch Economy Power receptacle housing that accepts the matching crimp terminals. The friction lock on this header engages with the lock ramp on the receptacle.
