What are the key features of TSM-139-04-T-DV-P-TR?
- 78-position dual-row layout on 0.100 inch (2.54 mm) pitch, providing 39 pins per row for versatile high-density interconnects
- Surface-mount termination style with tape-and-reel (TR) packaging for automated pick-and-place assembly
- Dual-beam contact design ensures reliable electrical connection over multiple mating cycles
- Compatible with SAMTEC SSM and SSW series socket strips for matched board-stacking solutions
What is TSM-139-04-T-DV-P-TR used for?
The TSM-139-04-T-DV-P-TR is used in board-to-board stacking assemblies, backplane interconnects, and module daughter-card designs that require 78-position connectivity on the industry-standard 0.100 inch pitch. Its tape-and-reel packaging enables high-volume automated PCB assembly in industrial computing, test instrumentation, and embedded systems. The dual-row format halves the connector length compared to a single-row strip, saving valuable PCB real estate in compact enclosures.

Frequently Asked Questions
How many positions and rows does the TSM-139-04-T-DV-P-TR provide, and what is the pin pitch?
The TSM-139-04-T-DV-P-TR provides 78 positions arranged in 2 rows of 39 pins on a 0.100 inch (2.54 mm) pitch. This standard pitch is widely used in backplane and module interconnect designs, ensuring broad compatibility with mating socket strips and daughter cards.
What does the TR suffix indicate for the TSM-139-04-T-DV-P-TR, and how does it affect assembly?
The TR suffix indicates tape-and-reel packaging, which enables automated pick-and-place machine handling during PCB assembly. Tape-and-reel delivery reduces manual loading time for the 78-position connector and maintains consistent placement accuracy across high-volume production runs compared to tray or loose packaging.
Which SAMTEC socket series is recommended to mate with the TSM-139-04-T-DV-P-TR?
SAMTEC SSM and SSW dual-row socket strip series sharing the 0.100 inch pitch are the recommended mating halves for the TSM-139-04-T-DV-P-TR. Selecting a socket with the appropriate stack height achieves a reliable board-to-board connection across all 78 positions with full electrical and mechanical engagement.
In what types of systems is the TSM-139-04-T-DV-P-TR commonly used?
This terminal strip is commonly used in industrial single-board computers, test-and-measurement backplanes, FPGA evaluation boards, and embedded module stacking applications. The 78-position count on 0.100 inch pitch supports data buses, power distribution, and control signals in systems requiring dense interconnects between a main board and 1 or more daughter cards.
