Samtec Inc. Header, 2.54 Mm, Through Hole, 63 Contacts; Connector Systems Samtec TSW-121-14-S-T

The Samtec Header, part number 02R3977, features a 2.54 mm pitch and is designed for through-hole mounting with 63 contacts arranged in three rows. The header is compatible with various mating connectors, including SSW, SSQ, SSM, and others. It is constructed from black glass-filled polyester for the TSW version and natural liquid crystal polymer for the HTSW version. The terminals are made of phosphor bronze with options for 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, with a maximum of 550 VAC for SSW and lower ratings for other types. The current rating per pin varies based on the mating connector, with values ranging from 4.3 A to 6.3 A. The header is RoHS compliant and offers lead-free solderable options for the HTSW variant. 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.
