Samtec Inc. Header, 2.54Mm, Though Hole Vertical, 44 Position; Connector Systems Samtec TSW-122-19-G-D-LL

The Samtec Header, part number 02R4409, features a 2.54 mm pitch and is designed for through-hole vertical mounting with 44 positions across 2 rows. It is compatible with various mating connectors including SSW, SSQ, SSM, and others. The header is constructed with a black glass-filled polyester insulator and utilizes phosphor bronze for the terminals, which are available with either gold or tin plating over nickel. This product operates within a temperature range of -55 ¬8C to +125 ¬8C when gold-plated, and -55 ¬8C to +105 ¬8C with tin plating. The voltage ratings vary depending on the mating connector, ranging from 400 VAC to 550 VAC. The current rating per pin varies based on the mating connector, with maximum ratings up to 6.3 A. The header is RoHS compliant and suitable for lead-free soldering, although lead wave soldering is required for the TSW version. Engineers should consider this header for applications requiring reliable board-to-board connections with specific voltage and current ratings, as well as compliance with environmental regulations.
