What are the key features of TST-104-03-G-D?
- 8 positions on 0.100" (2.54 mm) pitch in a dual-row shrouded format for polarized cable mating
- 10 µin gold over 50 µin nickel contact finish delivers low contact resistance and corrosion resistance across many mating cycles
- Phosphor bronze contact material provides excellent spring retention and reliable electrical continuity under vibration
- Compact 0.7" body length fits into tight PCB areas where larger shrouded headers would not clear adjacent components
What is TST-104-03-G-D used for?
The TST-104-03-G-D is used in embedded systems, sensor modules, and development boards where a small 8-pin cable interface is needed with polarity protection. Its shrouded dual-row 0.100" pitch design is common in robotics and industrial I/O modules for connecting discrete digital signals, SPI buses, or UART interfaces to external cable assemblies. The gold contact finish makes it suitable for test fixtures and prototype hardware requiring reliable connections after repeated mating.

Frequently Asked Questions
What contact finish does the TST-104-03-G-D use, and how does it affect connector longevity?
The TST-104-03-G-D uses 10 µin of gold over 50 µin of nickel on the mating surface. This gold thickness is sufficient for hundreds of mating cycles while maintaining contact resistance below 20 mΩ, making the 8-position header suitable for test equipment, prototype boards, and any application requiring repeated plug-and-unplug operations.
How does the shrouded design of the TST-104-03-G-D prevent mis-mating in cable harness applications?
The polarized shroud on the TST-104-03-G-D ensures that a compatible cable connector can only be inserted in the correct orientation. For an 8-pin dual-row header, reversing the cable would swap power and signal pins, but the shroud physically blocks off-orientation insertion, protecting sensitive circuits at 3.3V or 5V logic levels.
Which cable connector series mates with the TST-104-03-G-D for a 0.100" pitch harness?
The TST-104-03-G-D is designed to mate with SAMTEC's TST series cable sockets and compatible 0.100" (2.54 mm) pitch dual-row housing assemblies with female contacts. The 8-position dual-row format also accepts standard IDC ribbon cable connectors using 16-conductor ribbon for common prototyping and embedded system wiring applications.
When is the compact TST-104-03-G-D body size an advantage over a larger 0.100" pitch header?
The TST-104-03-G-D body measures only 0.7 inches long and 0.365 inches wide, making it one of the smallest 8-position dual-row shrouded headers available in the 0.100" pitch family. This size is advantageous on densely populated PCBs where a longer header would overlap adjacent components or violate courtyard clearance rules in high-density embedded module designs.
