TSM-139-02-T-DV-A

Headers, Male Pins Overview

The TSM-139-02-T-DV-A is a surface mount terminal strip from the Samtec TSM series, designed for high-density interconnect applications. It features 78 positions arranged in a dual-row configuration with a 2.54 mm (0.100 inch) pitch. The connector utilizes phosphor bronze contacts with tin plating and an LCP insulator rated UL 94 V-0. Operating within a temperature range of -55°C to 105°C, it supports current ratings between 4.1 A and 5.4 A and withstands voltages up to 495 VAC. The straight, male pin design facilitates reliable board-to-board or cable connections via solder termination.

Headers, Male Pins Procurement Notes

Verify the specific contact plating and post height against project requirements, as variations exist within the TSM-139 family. Confirm that the tin-plated variant aligns with solderability standards and environmental exposure limits. Ensure the surface mount package matches the PCB footprint dimensions precisely to avoid alignment issues during reflow. Cross-reference the voltage and current ratings with the actual load conditions to maintain operational safety margins.

Headers, Male Pins Selection Notes

Choose this component when a rigid surface mount header with standard 0.100-inch spacing is required. The tin-plated finish suits general-purpose applications where gold plating is unnecessary. Consider the dual-row format for maximizing I/O count in constrained spaces. Evaluate the operating temperature range to ensure compatibility with the device's thermal profile. This model is suitable for designs prioritizing cost-effective, high-reliability interconnects over specialized signal integrity needs.

Headers, Male Pins Part Context

This part belongs to the TSM series of .100-inch surface mount terminal strips. The series offers various row counts and contact configurations to support diverse mounting needs. The TSM-139 designation indicates a 78-position capacity, while the suffixes define the plating and termination style. It serves as a standard interconnect solution within Samtec's broader portfolio of flexible stacking and board-to-board connectors.

Headers, Male Pins Replacement Considerations

TSM-139-02-L-DV-A offers gold-plated contacts instead of tin. TSM-139-03-T-DV-A shares the same position count and pitch but may differ in mating length specifications.
