What is TST-125-01-S-D used for?
The TST-125-01-S-D is used in high-density board-to-cable and board-to-board signal routing applications in industrial control systems, military electronics, and test and measurement equipment where 50 positions of reliably mated 0.100 inch pitch contacts are required. The shrouded design and gold-plated contacts make it well suited for high-cycle mating environments and safety-critical connections demanding contact resistance stability over thousands of insertions.

Frequently Asked Questions
What contact finish does the TST-125-01-S-D use, and how does it affect mating reliability over many insertion cycles?
The TST-125-01-S-D features 30 µin gold plating over 50 µin nickel on the mating surfaces and tin over nickel on the solder termination, providing low contact resistance and corrosion resistance that sustains reliable electrical connection across hundreds of mating cycles in the 50-position 0.100 inch pitch header.
Why does the shrouded housing on the TST-125-01-S-D matter for high-density PCB assemblies?
The shrouded body measuring 2.8 inch length and 0.365 inch depth physically guides the mating receptacle into correct alignment across all 50 positions at 0.100 inch pitch, preventing bent pins and mis-mating errors that become increasingly likely as position count increases and manual assembly tolerances accumulate.
How quickly can the TST-125-01-S-D be sourced for an urgent NPI build, and what makes its lead time competitive?
The TST-125-01-S-D carries a 1-week factory lead time from Samtec, which is significantly shorter than typical 4 to 20-week lead times for specialty connectors, and its YTEOL rating of 9.1 years indicates a long active lifecycle with low obsolescence risk for multi-year production programs.
In which industrial or defense applications is the TST-125-01-S-D's phosphor bronze contact material a preferred choice?
Phosphor bronze contacts in the TST-125-01-S-D provide superior spring-back retention force and fatigue resistance compared to brass, making this 50-position 0.100 inch pitch header preferred for military backplane connectors, industrial PLC I/O modules, and test fixture interfaces that require consistent normal force over 500 or more mating cycles.
