Mating pin length is 0.240" (6.10 mm), post length 0.107" (2.71 mm), overall contact length 0.437" (11.10 mm) — the post is short enough for single-sided boards but may not clear thick backplane laminates; check the board thickness against the post length before layout.
Plating grade and mating cycle life
Mating finish is tin at 150.0 µinch (3.81 µm) — triple the thickness of typical tin flash on commodity headers. In a test-fixture or programming jig where the connector is mated hundreds of times, the thicker tin layer resists fretting corrosion and maintains contact resistance longer than a standard 30–50 µinch tin finish. Post finish is tin as well, which matches the solderability requirement for wave-solder or hand-solder assembly — no gold on the termination side, so the solder joint forms on tin rather than a mixed-metal interface.
Applications listed include Automotive, General Purpose, Lighting, Medical, Telecommunications — the tin finish and LCP housing suit indoor and sheltered environments, not washdown or outdoor exposure.
