Applications include general-purpose, industrial, and medical equipment. Available through independent distribution channels. Sourced per your BOM quantity against a quote. The 0.091\" (2.30mm) insulation height and dual-row layout require a matching header with a compatible stack height. Confirm the header's mated height against your board-to-board spacing budget before ordering. ## Contact Finish and Reliability Mating contacts are gold over phosphor bronze with 30.0µin gold thickness — this is a robust plating grade for applications requiring hundreds of mating cycles. For lead-free soldering requirements, a tin-plated post variant (if available in the series) would be needed — this specific order code carries tin-lead on the termination side.","metaTitle":"55508-138 Amphenol ICC (FCI) Minitek 2.00mm 38-Pin","metaDescription":"55508-138 obsolete board-to-board receptacle, 2.00mm pitch, 38 positions, gold 30µin mating finish, 2A.
