What are the key features of TSM-139-05-TL-DV-P-TR?
- 78-position dual-row layout at 0.100" (2.54 mm) pitch for high pin-count surface mount interconnect applications
- 3A per pin current rating with gold-plated contacts providing robust electrical performance across thousands of mating cycles
- Tape-and-reel (TR) packaging enables automated SMT pick-and-place assembly for high-volume production
What is TSM-139-05-TL-DV-P-TR used for?
The TSM-139-05-TL-DV-P-TR is suitable for high-density board-to-board interconnect in industrial control systems, test-and-measurement backplanes, and embedded computing platforms requiring 78 signals on a standard 0.100" pitch footprint. Its dual-row surface mount design allows seamless integration into automated reflow assembly processes, improving throughput for large-volume production runs. The connector also serves well in FPGA prototyping boards and data acquisition systems where a high signal count and reliable contact performance are critical.

Frequently Asked Questions
How many pins does TSM-139-05-TL-DV-P-TR provide, and how is the dual-row layout arranged?
TSM-139-05-TL-DV-P-TR offers 78 pins arranged in 2 rows at 0.100" (2.54 mm) pitch, with 39 pins per row. This standard dual-row layout is compatible with a wide range of mating headers and socket connectors, making it easy to source matched counterpart components from multiple vendors for board-to-board stacking applications.
For a high-current industrial control backplane, how much current can TSM-139-05-TL-DV-P-TR carry per pin?
The TSM-139-05-TL-DV-P-TR is rated at 3A per pin, enabling it to carry combined power and signal loads across its 78 contacts in industrial motor drives, PLCs, and power distribution backplanes. With 78 pins at 3A each, the connector can theoretically support aggregate current loads well above 100A when multiple pins are paralleled for dedicated power rails.
How does TSM-139-05-TL-DV-P-TR compare to a through-hole equivalent for a production SMT assembly line?
Unlike through-hole terminal strips that require wave soldering or manual insertion, the TSM-139-05-TL-DV-P-TR uses surface mount termination compatible with standard 260°C peak reflow profiles. This allows it to be placed on the same SMT line pass as capacitors and ICs, eliminating a separate wave-solder step and reducing assembly cost per board in production volumes.
Over what temperature range does TSM-139-05-TL-DV-P-TR reliably operate, and which environments qualify?
TSM-139-05-TL-DV-P-TR operates across -55°C to +125°C, covering the full commercial, industrial, and military temperature ranges. This makes it suitable for outdoor telecoms enclosures, automotive under-hood electronics, and airborne test equipment where ambient temperatures swing widely and contact reliability must be maintained without derating the 3A per pin current rating.
