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.","metaTitle":"Amphenol BERGSTIK II 78511-103HLF, 3-Pin Header","metaDescription":"Amphenol BERGSTIK II 78511-103HLF 3-position unshrouded header, 0.100\" pitch, 5A, gold-plated contacts, UL94 V-0.
