20 Position Receptacle Connector 0.100" (2.54mm) Through Hole Tin The SSQ-110-03-T-D is a through-hole dual-row socket strip receptacle connector manufactured by Samtec, designed for board-to-board and pin header mating applications using the industry-standard pitch spacing that has been dominant in through-hole PCB interconnect design for decades. It belongs to Samtec's SSQ series, a family of square-post socket strip connectors that accept standard square-pin headers and are widely used across prototyping, instrumentation, test and measurement, embedded systems, industrial control, and general-purpose PCB stacking applications. As a socket strip of the receptacle gender, the SSQ-110-03-T-D is intended to receive a mating male pin header, creating a reliable and separable board-to-board or wire-to-board connection. The dual-row configuration provides a higher contact density within a given board length than a single-row socket, which is why dual-row socket strips in this pitch class are extensively used in applications such as microcontroller and single-board computer expansion connectors, module-to-baseboard interfaces, and other designs where a significant number of signal, power, or ground connections must be made across a single separable connector interface. The connector features square solder tails for through-hole PCB mounting, with the "-T" suffix in the part number designating the square post tail style, which provides a well-defined mechanical footprint and reliable solder joint formation in wave solder and hand-solder assembly processes. The "-D" suffix indicates the dual-row configuration. Contact material is phosphor bronze, a widely used spring-contact alloy chosen for its combination of good electrical conductivity, excellent spring properties that maintain consistent contact force across many mating cycles, and resistance to stress relaxation over time. The contacts are finished with matte tin plating over nickel underplate, providing a solderable, cost-effective contact surface suitable for the majority of general-purpose signal and low-power applications for which this connector class is typically used. The insulator body is molded from black liquid crystal polymer, a high-performance engineering thermoplastic that offers the high dimensional stability, excellent electrical insulation properties, and high-temperature resistance needed to withstand wave soldering and reflow-adjacent thermal exposure during PCB assembly. The material also carries a UL94 V-0 flammability rating, reflecting its self-extinguishing behavior in the event of an ignition source, which is required or preferred in many end-product regulatory compliance frameworks. The SSQ series is widely used in conjunction with Samtec's TSW series male pin headers as a complementary mating pair, and the connector is compatible with a broad range of standard square-pin headers from other manufacturers that conform to the same pitch and pin geometry, making it a versatile choice for general-purpose through-hole header applications.
