What are the key features of TST-104-03-S-D?
- 8-position dual-row shrouded header with 0.100-inch (2.54 mm) pitch for standard board-to-board mating
- 30 µin gold-over-nickel mating contact finish ensures low contact resistance and long insertion-cycle life
- Tin-over-nickel termination finish on PCB tails provides solderability compatible with standard wave and reflow processes
- Rectangular square-pin contact pattern offers positive polarization to prevent mismate in dense PCB assemblies
What is TST-104-03-S-D used for?
The TST-104-03-S-D is used in test and measurement boards, development platforms, and modular PCB assemblies where reliable 0.100-inch pitch dual-row connectivity is required. Its shrouded design protects 8 contacts from accidental mismating during repeated plug-unplug cycles in lab and field environments. Engineers select this header for instrumentation backplanes, processor daughter cards, and signal breakout boards where gold contact finish ensures stable low-resistance connections over thousands of mating cycles.

Frequently Asked Questions
How many positions and rows does the TST-104-03-S-D provide, and what is its contact pitch?
The TST-104-03-S-D is a dual-row, 8-position header with a 0.100-inch (2.54 mm) contact pitch. The shrouded body measures 0.700 inch in length and 0.365 inch in width, fitting standard 2×4 footprints on through-hole PCBs.
For a test fixture requiring repeated plug-unplug cycles, how durable are the TST-104-03-S-D contacts?
The mating contacts feature 30 µin gold plating over a nickel barrier, which provides low and stable contact resistance through hundreds of insertion cycles. The square-pin style and shrouded housing guide mating connectors accurately, reducing wear and preventing misalignment in repeated-test-fixture applications.
What soldering process is compatible with the TST-104-03-S-D termination finish?
The PCB termination tails use tin (Sn) plating with a nickel (Ni) diffusion barrier, which is compatible with standard wave-soldering and hand-soldering processes. The 0.100-inch pitch through-hole tail geometry suits 1.0 mm drill holes, and the nickel barrier inhibits tin whisker formation for reliable long-term solder joints.
