Board fit and contact rating
The 100 µinch tin thickness on both post and mating finish gives a solid cold-weld interface on first mate, but tin frets under vibration if the connector is cycled often — this header suits fixed or infrequently disconnected harnesses.
The base product number is 102523, which covers the unpopulated header body and pin configuration. The full 5-102523-6 suffix specifies the 8-position, right-angle, tin-plated variant in tube packaging.
Thermal and material limits
Phosphor bronze contacts with tin plating: the base metal provides spring retention and moderate conductivity; the thick tin layer protects against corrosion in non-aggressive environments. For repeated mating cycles or corrosive atmospheres, a gold-plated sibling in the AMPMODU Mod II family would extend service life.
