5.00 mm pitch, shrouded, locking ramp — what this header does
The 3-1376387-4: This is a 6-position, 2-row, through-hole header from TE's Power Key series, pitched at 0.197" (5.00mm) with a row spacing of 0.244" (6.20mm).
Board fit and routing — what the pitch and stack height mean
At 5.00mm pitch, the board footprint is generous enough for 2- or 4-layer routing without micro-vias, and the 0.138" (3.50mm) solder tail length gives a solid through-hole joint.
