Key Features
- 3-position single-row board receptacle with 0.100" (2.54 mm) pitch for standard through-hole or SMT interconnect
- 10 µin gold over 50 µin nickel contact finish providing superior corrosion resistance and low contact resistance across repeated mate cycles
- Phosphor bronze contact material delivering spring force retention and mechanical durability for reliable signal connections
- RoHS-compliant lead-free design supporting REACH and global environmental export compliance
- Compact 0.196 inch body breadth optimized for space-constrained PCB layouts in instrumentation and computing modules
Applications
The TMS-103-01-G-S is used in low-voltage signal interconnection on PCBs across test and measurement equipment, embedded computing boards, and industrial control modules where a compact 3-pin receptacle with durable gold contacts is required. Its phosphor bronze contacts and gold plating make it well suited for applications requiring hundreds of mate-unmate cycles without degradation, such as modular sensor interfaces or reconfigurable daughtercard systems. The 0.100-inch pitch is compatible with standard jumper and cable assemblies, simplifying integration into existing designs.

Frequently Asked Questions
What contact finish does the TMS-103-01-G-S use and how many mate cycles can it reliably support?
The TMS-103-01-G-S features 10 µin (0.25 µm) gold plating over 50 µin (1.27 µm) nickel barrier on phosphor bronze contact material. Gold-over-nickel finish typically supports 100 to 500 mate-unmate cycles before measurable contact resistance increase, with initial contact resistance below 20 milliohms. This makes it suitable for semi-permanent board interconnects, test fixture interfaces, and field-serviceable module connectors.
How does the 3-position TMS-103-01-G-S compare to a 4-position connector for compact sensor interface designs?
For a 3-wire sensor interface such as a differential signal pair plus ground, the TMS-103-01-G-S provides exactly 3 positions at 0.100 inch pitch in a 0.196 inch body width, consuming minimal PCB footprint. A 4-position connector would add an unused pin and an extra 0.1 inch of connector length (totaling 0.4 inch row length), wasting board space. Choosing the TMS-103-01-G-S avoids unnecessary pin overhead while maintaining the standard 2.54 mm pitch for easy cable-harness compatibility.
What wire or mating connector is compatible with the TMS-103-01-G-S for a cable assembly?
The TMS-103-01-G-S mates with SAMTEC's TSW-series or TMM-series male header pins at 0.100 inch (2.54 mm) pitch. Standard DuPont-style jumper wires with 2.54 mm female crimp housings using 22 AWG to 26 AWG wire are also compatible and support current ratings up to 1 A per contact at ambient temperatures below 70°C. This broad compatibility simplifies prototype and production cabling without custom tooling.
Is the TMS-103-01-G-S suitable for use in a 3.3 V logic bus connection on an embedded MCU board?
Yes, the TMS-103-01-G-S is well suited for 3.3 V logic bus connections. The gold-over-nickel contact finish maintains contact resistance below 20 milliohms, ensuring minimal voltage drop at logic signal currents typically under 50 mA per pin. The phosphor bronze spring contacts reliably retain the mating header without mechanical loosening under vibration, meeting the demands of embedded MCU boards in industrial or automotive-adjacent applications.
