The 8-1735480-0 is a vertical PCB-mounted receptacle connector designed for board-to-board interconnection with 200 positions arranged in dual rows. It features a 0.8 mm free height and offers configurable board-to-board stack heights of 17.00 mm, 18.00 mm, 19.00 mm, or 20.00 mm to accommodate various PCB spacing requirements. The connector utilizes gold (30) plating on the mating area contacts over a copper alloy base, with solder tail contacts plated in tin over nickel for reliable soldering. The housing is constructed from liquid crystal polymer (LCP) with a UL 94V-0 flammability rating and includes locating posts for precise alignment. This connector is RoHS and ELV compliant, supports reflow soldering up to 260°C, and is ideal for high-density interconnection applications in computing, telecommunications, and industrial equipment where reliable board-to-board connections are essential.
