What Crosses Into the Harness You've Got
If you're re-pinning a board that originally used this header, the 0.100" pitch and 6-position dual-row layout are the industry-standard footprint. Any unshrouded breakaway header with the same pitch, row spacing, and 0.100" insulation height will fit the PCB holes — but the mating finish and overall contact length differ between suppliers. Confirm the 0.480" overall contact length and 0.266" mating length before swapping. Tin-plated alternatives are cheaper but drop the mating cycle life from the 30 µinch gold baseline — in a field-service board that gets cycled quarterly, the gold finish is worth sourcing.
