Unshrouded Breakaway for Flexible Routing
The 9-146282-0-04: Unshrouded breakaway header — the pins are exposed after soldering, which gives the board layout engineer maximum flexibility for trace routing around the footprint.

Peer Comparison: Shrouded vs Unshrouded
The closest functional alternative is TE 1-1871673-2 — a 4-position, 2-row, shrouded header with a detent lock and board lock. That part adds vibration-resistant mating and a 250VAC/DC rating, but at a different pitch (0.098" / 2.50mm) and right-angle orientation. The 9-146282-0-04 remains the simpler, lower-profile choice for straight-through board-to-board or cable connections.
