This header mates with TE Economy Power receptacle housings that accept 18-22 AWG crimp terminals. ## Peer Comparison: 4-1775099-7 vs 1744057-4 The closest functional alternative is 4-1775099-7, also a 4-position, 3.96mm pitch, single-row header from the same Economy Power series. The key difference: 4-1775099-7 uses a fully shrouded housing (4 walls) versus the 1-wall shroud on 1744057-4. If your application requires full pin protection on all sides, the 4-1775099-7 is the better fit; if board-edge clearance is tight, the 1-wall shroud of 1744057-4 saves space.","metaTitle":"1744057-4 TE Connectivity Economy Power Header 4 Pos 3.96mm","metaDescription":"1744057-4 TE Connectivity AMP Economy Power header, 4 pos, 3.96mm pitch, 7.5A, 250VAC, tin-plated, friction lock, active, RoHS.
