TSW-103-07-LS – SAMTEC

The TSW-103-07-LS is a three-position, 2.54mm (0.100″) pitch, through-hole mount, square post header manufactured by Samtec. This component is RoHS compliant, indicating adherence to Restriction of Hazardous Substances directives. The header features a single row of pins, designed for vertical mating with compatible Samtec sockets or cable assemblies. Pin length is determined by the specific dash number within the TSW series, influencing board stacking height and mating characteristics. The insulator material is typically a high-temperature thermoplastic, suitable for reflow soldering processes. The contact material is generally a copper alloy, often plated with gold or tin over nickel to provide optimal conductivity and corrosion resistance. The “LS” suffix suggests a lead style, likely indicating a standard straight termination.
