What are the key features of TSM-139-05-STL-DV-P-TR?
- 78-position dual-row 0.100 inch pitch layout delivers high-density signal routing in a low-profile surface-mount package
- Shrouded and polarized (STL) housing prevents misalignment and reversed-insertion errors during mating, improving reliability in field-serviceable designs
- Tape-and-reel (TR) delivery enables automated pick-and-place assembly for efficient high-volume PCB production
What is TSM-139-05-STL-DV-P-TR used for?
TSM-139-05-STL-DV-P-TR is used in dense multi-signal interconnects for industrial control boards, FPGA carrier modules, and data acquisition systems where a large number of differential and single-ended signals must be routed through a compact, polarized SMT connector. The shrouded low-profile design with tape-and-reel packaging suits automated assembly of server backplanes, test fixtures, and modular instrumentation platforms.

Frequently Asked Questions
What pin count and pitch does TSM-139-05-STL-DV-P-TR use, and how does the shrouded housing improve assembly reliability?
The TSM-139-05-STL-DV-P-TR provides 78 positions in a dual-row layout with a 0.100 inch (2.54 mm) pitch. The shrouded housing aligns the mating connector onto the 39 contacts per row with mechanical guidance, reducing misalignment risk compared to open-pin headers and preventing reversed-insertion damage in automated board-to-cable assembly.
How does the low-profile shroud of TSM-139-05-STL-DV-P-TR affect clearance requirements in densely populated PCB designs?
The STL (short low-profile) designation means the shroud height is minimized, typically around 3.5 mm above the PCB surface for a 0.100 inch pitch SMT strip. This allows adjacent components to be placed closer to the connector, saving board space in high-density designs such as FPGA mezzanine cards where vertical clearance between stacked boards may be as little as 8 mm.
For a design requiring 78 signals in a single SMT connector, when should TSM-139-05-STL-DV-P-TR be preferred over multiple smaller connectors?
A single 78-pin TSM-139-05-STL-DV-P-TR reduces PCB routing complexity and lowers assembly cost compared to three 26-pin connectors, saving 2 additional pick-and-place cycles per board. It is preferred when all 78 signals are functionally related (e.g., a full parallel data bus or FPGA I/O bank) and the shrouded polarized housing prevents mismatched cable connections during field maintenance.
