Frequently Asked Questions
How many positions and what row arrangement does the TSM-139-03-L-DV-P-TR terminal strip use?
The TSM-139-03-L-DV-P-TR features 78 positions arranged in a dual-row format with 39 contacts per row, using a standard 0.100" (2.54 mm) pitch. This configuration provides a high signal count suitable for embedded computing modules, industrial I/O boards, and communication backplanes requiring dense SMT pin-header connectivity.
What does the TR suffix indicate about the packaging of the TSM-139-03-L-DV-P-TR?
The TR suffix stands for Tape-and-Reel packaging, meaning the TSM-139-03-L-DV-P-TR components are supplied on continuous reels for automated pick-and-place assembly. This is ideal for high-volume PCB manufacturing environments where manual placement of individual connectors would be impractical for a 78-position dual-row 0.100" pitch surface mount terminal strip.
Can the TSM-139-03-L-DV-P-TR be used as a lower-density alternative to custom flex cable assemblies in embedded module designs?
Yes. For embedded module designs needing up to 78 signal connections, the TSM-139-03-L-DV-P-TR provides a direct board-to-board interconnect with a rigid SMT interface at 0.100" (2.54 mm) pitch, avoiding the cost and complexity of custom flex cable assemblies. The dual-row configuration in a standard 2.54 mm pitch format also simplifies PCB routing compared to fine-pitch flex connectors.
Which SAMTEC socket series mate with the TSM-139-03-L-DV-P-TR for a complete 0.100" pitch board-to-board pair?
The TSM-139-03-L-DV-P-TR mates with SAMTEC SFM and SFS series socket strips in the 0.100" (2.54 mm) pitch dual-row configuration. These 78-position socket counterparts complete the board-to-board or board-to-module interconnect system, supporting applications in industrial automation, communications, and embedded computing platforms requiring reliable dual-row connector pairs.
