72-Position Breakaway Header — Board Footprint and Fit
The 75844-124-72: The dual-row layout with 0.100" row spacing gives you a 0.200" x 1.800" board footprint approximate; the 0.284" mating pin length and 0.120" solder tail depth set the z-height and through-hole drill depth. In a production harness that sees quarterly reconnects, the gold interface resists fretting corrosion well beyond the product's service life.
Obsolete — Sourcing Reality and Cross-Reference
The BergStik series includes many 72-position, 0.100" pitch headers with similar dimensions, but the exact pin length and plating combination may not be drop-in — a board re-spin or alternate sourcing through independent channels is the practical path.
The square pins accept wire-wrap or press-fit into solderless breadboards.
