7-Position Single-Row Breakaway Header
It mates with standard 2.54mm pitch receptacles for board-to-board or cable-to-board connections. The tin-plated solder tails (100 µinch) handle the board-level connection without extra plating cost.
Board Fit and Contact Geometry
The square male pin (Copper Alloy) ensures reliable contact wipe on insertion. Insulation height is 0.090" (2.29mm) — low enough for tight board stacking when the mating receptacle is mounted on the opposing board.
Peer Comparison: Gold Thickness and Row Count
The closest functional sibling is 5-146280-7 — same 7-position single-row layout, same 3 A rating, same gold mating finish, but the 5-146280-7 uses 15 µinch gold instead of 30 µinch. For applications requiring higher mating-cycle durability, the 9-146277-0-07's 30 µinch gold is the better choice. The 9-146257-0 is a dual-row 80-position variant — different footprint entirely.
