What are the key features of TSM-139-03-G-DV-P-TR?

  • 78-position dual-row layout on a 0.100" (2.54 mm) pitch for high-density board-to-board signal distribution in a compact footprint
  • Gold-plated contact finish providing low contact resistance below 20 mΩ and reliable mating cycles exceeding 30 insertion cycles in harsh environments
  • Tape-and-reel (TR) packaging enabling automated pick-and-place assembly at high production volumes with consistent component orientation

What is TSM-139-03-G-DV-P-TR used for?

The TSM-139-03-G-DV-P-TR is designed for backplane interconnects, daughter-card interfaces, and high-density signal routing in industrial control systems and test equipment where a 78-position dual-row 0.100" pitch SMT terminal strip is required. Its gold-plated contacts make it suitable for low-level signal applications in laboratory instruments and data acquisition boards. The tape-and-reel format allows seamless integration into automated PCB assembly lines servicing communications hardware and embedded computing modules.

Frequently Asked Questions

How many positions and rows does the TSM-139-03-G-DV-P-TR provide, and at what pitch?

The TSM-139-03-G-DV-P-TR offers 78 positions arranged in 2 rows at a 0.100" (2.54 mm) pitch, delivering high-density signal connectivity in a surface-mount footprint suitable for backplane and daughter-card applications with up to 39 pins per row.

What contact finish does TSM-139-03-G-DV-P-TR use, and how does that affect connector reliability?

The TSM-139-03-G-DV-P-TR uses a gold (Au) contact finish, which provides a contact resistance below 20 mΩ and resists oxidation over more than 30 mating cycles. This makes it well-suited for low-current signal lines in test and measurement equipment where stable electrical performance is critical.

Can TSM-139-03-G-DV-P-TR be used in automated SMT assembly, and what packaging does it ship in?

Yes, the TSM-139-03-G-DV-P-TR ships in tape-and-reel (TR) format, enabling automated pick-and-place assembly at high production volumes. The reel packaging maintains consistent 0.100" pitch component orientation through standard SMT reflow processes operating up to 260°C peak temperature.

What alternative SAMTEC part should I consider if I need fewer than 78 positions in the same 0.100" dual-row SMT series?

SAMTEC offers the TSM series in various position counts at the same 0.100" (2.54 mm) dual-row pitch. For example, TSM-120-xx-x-DV-P-TR provides 40 positions (20 per row) and TSM-130-xx-x-DV-P-TR provides 60 positions, both sharing the same mating interface and tape-and-reel packaging as the 78-position TSM-139 variant.
