What are the key features of TSM-139-03-F-DV-P-TR?
- 78-position dual-row surface mount layout at 2.54 mm (0.100 inch) pitch enables high-density signal routing in a compact SMT footprint
- Tape-and-reel (TR) packaging supports high-volume automated SMT pick-and-place assembly with consistent placement accuracy
- Dual-row vertical (DV) orientation provides mechanical stability and high pin count in a narrow PCB footprint, reducing board area requirements
What is TSM-139-03-F-DV-P-TR used for?
The TSM-139-03-F-DV-P-TR is well suited for dense signal-routing applications in test-and-measurement equipment, industrial controllers, and embedded computing backplanes where a large number of I/O lines must be terminated in a compact surface mount form factor. Its 78-position dual-row layout efficiently handles parallel buses, GPIO arrays, and mixed signal/power connections. The tape-and-reel packaging makes it ideal for automated high-volume PCB assembly lines.

Frequently Asked Questions
How many positions does the TSM-139-03-F-DV-P-TR have and what is its contact pitch?
The TSM-139-03-F-DV-P-TR provides 78 positions arranged in 2 rows on a 2.54 mm (0.100 inch) pitch, giving designers 39 contacts per row for connecting dense signal buses or mixed power-and-signal circuits on a single SMT strip.
What packaging format does the TSM-139-03-F-DV-P-TR use and how does it affect assembly line setup?
The connector ships in tape-and-reel (TR) format, compatible with standard 8 mm to 16 mm SMT pick-and-place feeders. This eliminates manual hand-loading of 78-pin strips and supports production throughput exceeding 1000 placements per hour on modern SMT lines.
In which embedded or industrial applications does the dual-row vertical orientation of this connector provide the greatest benefit?
Industrial PLC backplanes, data acquisition front-ends, and embedded SBC expansion headers benefit most. The dual-row vertical (DV) profile keeps the 78-position strip within a narrow 5.08 mm row-to-row span, leaving more board space for power conditioning and RF components.
How does the TSM-139-03-F-DV-P-TR compare to a single-row 78-position strip for PCB real estate?
A dual-row 2.54 mm strip with 78 positions spans roughly 50.8 mm in length (39 contacts × 2.54 mm), whereas a single-row equivalent would require approximately 198 mm — saving nearly 147 mm of board length and significantly reducing PCB size for the same 78-signal capacity.
