Why a 4-Wall Shroud Matters for This Header
The 10073456-044LF: Pitch is 0.100" (2.54mm) with matching row spacing, so the board footprint is standard 0.100" grid — no special routing or oddball keep-out zones.
Press-Fit Termination for Backplane and High-Reliability Builds
Termination is press-fit with a solder tail option — the press-fit compliant pin eliminates the need for a wave solder step, which is preferred in backplane assemblies where rework access is limited and solder joint inspection is impractical.
No stock-holding claim — each order is quoted individually.
The keying slot in the shroud prevents mismating with receptacles that lack the matching key — a simple but effective way to avoid wiring errors in multi-connector panels. Packaged in tray format, which is standard for through-hole headers of this size — no tape-and-reel, so hand placement or tube-fed insertion is expected.
