Board-to-Board Header for Standard DIP Footprints
The 0.900" (22.86mm) mating pin length gives it reach through a typical PCB or into a mating receptacle, while the 0.225" (5.72mm) solder tail provides a solid through-hole joint.
Single-Row Layout and Pitch Match
The 24 positions are all loaded in a single row on 0.100" (2.54mm) centers. That's the same pitch as standard DIP ICs and Berg strip headers, so it drops into a common footprint. The single-row arrangement means the board layout is a straight line of 24 plated through-holes — no second row to route.
Tin-Plated Contacts — Signal Duty, Not High-Cycle
Tin-on-tin contacts are cost-effective for one-time or infrequent mating, but they gall and oxidize under repeated insertion cycles. For a header that gets mated once in production and stays there, this is fine. The phosphor bronze base material gives decent spring properties for the contact beam.
