The Socket, 2.54mm, Vertical Through Hole, 35 Position (part number 84T3374) is designed for board-to-board applications with a pitch spacing of 2.54mm. It features a single row with 35 contacts and is suitable for through-hole mounting. The insulator material is black glass-filled polyester, while the contacts are made of phosphor bronze with options for gold or tin plating over nickel. This socket has a current rating of 5.2 A per pin for the ESW series and 5.7 A per pin for the ESQ series, with a voltage rating of 550 VAC when mated with compatible connectors. The operating temperature range is -55°C to +125°C with gold plating and -55°C to +105°C with tin plating. The contact resistance is specified at 10 mΩ, and the product is RoHS compliant and lead-free solderable, suitable for wave soldering only. Engineers should consider this socket for applications requiring reliable electrical connections in compact spaces, particularly where low insertion force options are beneficial.
