The Amphenol ICC 78511-103HLF is a 3-position, single-row male pin header from the BERGSTIK® II series. It uses the standard 0.100" (2.54mm) pitch, making it a direct fit for breadboard, perfboard, and standard DIP IC footprints. Rated at 5A per circuit with a 110V voltage rating, it handles typical signal-level and low-power board-to-board interconnects. The unshrouded square pins with a 0.318" (8.08mm) mating length provide a clean push-pull connection for applications where a low-profile, non-keyed interface is acceptable.
Plating and Contact Design
The mating contacts are finished with 30.0µin (0.76µm) of gold over a phosphor bronze base. That gold thickness is the key differentiator here — it supports hundreds of mating cycles without the oxidation or fretting corrosion you get with tin-plated headers. For a board that sees periodic rework or field-service disconnects, this plating grade is what keeps contact resistance stable over the life of the assembly.
Environmental and Mechanical Ratings
The housing is molded from Liquid Crystal Polymer (LCP) with a UL94 V-0 flammability rating. The operating temperature range spans -65°C to 125°C.
Sourcing and Lifecycle
The 78511-103HLF carries an active lifecycle status. No official successor or cross-reference is on record — this is the current production part for the BERGSTIK II 3-position unshrouded header.
