What This 13-Position Unshrouded Header Does
The 1-1546931-3: It carries a UL-rated 12 A per contact at 300 V, with the tin-plated brass contacts suited for moderate cycle counts in controlled environments. The vertical header orientation and 0.138" (3.50 mm) contact tail length fit standard through-hole board layouts. A distinguishing feature is side stacking — the header can be ganged side-by-side on the same pitch to build wider multi-row assemblies without custom tooling.

Board Fit and Routing at 5.00 mm Pitch
Vertical through-hole mounting with a 0.138" tail length suits single-layer or double-layer boards where the header sits perpendicular to the board plane.
