Applications
The SAMTEC TMS-103-02-G-S is designed for board-to-board signal interconnect applications in embedded computing, industrial automation, and communications equipment requiring reliable low-resistance connections. Its gold-plated phosphor bronze contacts ensure consistent electrical performance across thousands of mating cycles in test fixtures, development boards, and module-to-baseboard interfaces. The compact 2.54mm pitch receptacle makes it well-suited for space-constrained PCB designs where signal integrity and mechanical retention are both critical.

Frequently Asked Questions
What contact finish does the TMS-103-02-G-S use and how does it affect mating cycle life?
The TMS-103-02-G-S features gold (10 µin) over nickel (50 µin) plating on phosphor bronze contacts. This finish combination delivers low contact resistance typically below 20 mΩ and supports hundreds to thousands of mating cycles without significant oxidation, making it ideal for test sockets, development boards, and production modules that require repeated connect-disconnect operations.
For a compact embedded module design, how does the 2.54mm pitch of TMS-103-02-G-S compare to finer-pitch alternatives?
At 2.54mm pitch, the TMS-103-02-G-S uses the industry-standard 0.100" grid, which is compatible with a wide range of mating headers and PCB routing tools. Compared to 1.27mm or 2.00mm pitch alternatives, the 2.54mm grid allows wider trace spacing and easier manual soldering for prototyping, while still fitting within a 0.196-inch body breadth footprint suitable for compact embedded module baseboard designs.
How quickly can the TMS-103-02-G-S be sourced for a time-critical production run?
SAMTEC lists a 1-week factory lead time for the TMS-103-02-G-S, making it one of the faster-available connector options for production schedules. For urgent needs, authorized SAMTEC distributors may stock units for same-day or next-day shipment, enabling procurement teams to secure 6-position dual-row connectors without the 4 to 12-week lead times common for custom or specialty connectors.
