- Samtec precision construction enabling reliable signal integrity across multiple insertion cycles in test and production use
What is TST-102-01-H-D used for?
The TST-102-01-H-D provides a compact 4-circuit wire-to-board or board-to-board interface for embedded systems, development boards, and test fixtures where precise connector guiding and high-cycle durability are required. The 30 µin gold contact finish makes it ideal for frequently-mated connections such as debug headers, programming ports, and functional test jig interfaces where contact integrity must be maintained across hundreds of insertion cycles. Its small 0.500" body length suits densely populated PCBs in portable instruments, IoT modules, and industrial sensor nodes.

Frequently Asked Questions
What contact finish does the TST-102-01-H-D use, and how does 30 µin gold compare to gold flash for high-cycle applications?
The TST-102-01-H-D uses 30 µin (microinches) of gold over nickel on its mating contacts, which is substantially thicker than the 3–5 µin gold flash used on lower-cost connectors. The 30 µin plating depth withstands hundreds to thousands of mating cycles before the gold layer wears through, making it the preferred choice for test fixtures, programming jigs, and debug headers that are inserted and removed repeatedly during development and production test.
How small is the TST-102-01-H-D body, and what PCB footprint must be reserved for it?
The TST-102-01-H-D body measures 0.500 inch long by 0.365 inch wide and 0.365 inch deep, requiring a PCB footprint of approximately 0.183 square inches. This compact size allows the 4-position dual-row connector to fit on space-constrained boards such as IoT sensor modules, small embedded controllers, and compact industrial nodes where a standard 0.100" pitch header occupies minimal real estate.
For a benchtop test fixture that mates and un-mates hundreds of times daily, why choose TST-102-01-H-D over a lower-cost connector?
Standard gold-flash connectors with 3–5 µin plating begin to show wear after approximately 25–100 mating cycles. The TST-102-01-H-D's 30 µin gold plating over nickel maintains consistent low contact resistance (typically below 20 mΩ) through hundreds of daily cycles over months of production test use. The shrouded housing also guides the mating connector precisely across all 4 positions, preventing pin damage during rapid insertion in high-throughput test fixture environments.
Can the TST-102-01-H-D serve as a board-to-board connector, and what mating connector is compatible on a stacking application?
Yes, the TST-102-01-H-D can serve as a vertical board-to-board header when paired with a compatible Samtec 4-position dual-row 0.100" socket connector. The square-pin male contacts on the 0.500" body accept standard 2×2 mating housing assemblies, enabling a 4-circuit board stack with consistent 2.54 mm pitch alignment. This suits modular PCB designs where daughter cards plug directly onto a motherboard header with secure shroud-guided engagement.
