Pitch and Position Count Define the Board Fit
The 0532581229: In a single-row layout, the 0.138" (3.50 mm) post length gives enough standoff for wire-to-board mating without bottoming the housing.
The 4-wall shrouding also protects the pins from bent-contact damage during blind mating.
Termination Options: Press-Fit and Solder
Listed with both press-fit and solder termination, this header supports two assembly methods. Press-fit eliminates the solder wave for high-reliability backplane builds where rework is difficult; the through-hole solder tail gives a conventional joint for standard wave-solder lines. The square pin shape provides consistent contact geometry for both processes.
Tin Plating for Cost-Effective Signal Duty
The brass contact material provides adequate spring properties for the insertion force range of a single-row header.
