Product details

For higher reconnect duty, consider the gold-plated variants in the Economy Power series.

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.
