What are the key features of TST-102-01-S-D?
- 0.100 inch (2.54 mm) pitch dual-row shrouded header with polarizing shroud prevents mis-mating in dense PCB assemblies
- 30 µin gold-over-nickel mating contacts ensure low contact resistance and long mating cycle life exceeding 100 insertions
- Square pin contact style with tin-over-nickel termination provides excellent solderability for through-hole PCB mounting
- Compact body dimensions of 0.365 × 0.365 × 0.5 inch fit tight board layouts with 4-position dual-row configuration
What is TST-102-01-S-D used for?
The TST-102-01-S-D is suited for board-to-board and board-to-cable interconnect in industrial control systems, test and measurement equipment, and embedded computing modules requiring reliable 0.100 inch pitch connectivity. Its shrouded design prevents connector misalignment in automated assembly and field-service environments. The gold-mated contacts support high-cycle-life applications such as removable daughter cards, debug headers, and modular sensor interfaces.

Frequently Asked Questions
What pitch and contact finish does the TST-102-01-S-D use?
The TST-102-01-S-D uses a 0.100 inch (2.54 mm) contact pitch with 30 µin gold-over-nickel mating contacts. The termination side uses tin with a nickel barrier, providing corrosion resistance and reliable soldering in through-hole PCB applications.
How many positions and rows does the TST-102-01-S-D connector provide?
The TST-102-01-S-D is a 4-position dual-row (2×2) shrouded PCB header with a body dimension of 0.365 × 0.365 × 0.5 inch. This compact layout accommodates 4 signal or power contacts with polarized alignment in a standard 0.100 inch grid pattern.
In which PCB assembly scenarios does the TST-102-01-S-D shroud provide a design advantage?
The polarizing shroud on the TST-102-01-S-D prevents reverse mating during board assembly and field replacement, reducing assembly errors in automated pick-and-place operations. It is particularly valuable in industrial control modules, embedded systems with 3.3 V or 5 V logic rails, and test fixtures where repeated mating cycles of 50 or more insertions are expected.
What is a cost-effective alternative to the TST-102-01-S-D for high-volume PCB production?
For high-volume production with lower mating-cycle requirements (under 25 insertions), the SAMTEC TSW series offers a similar 0.100 inch pitch dual-row header with tin-plated contacts at lower unit cost. The TST-102-01-S-D is preferred when 30 µin gold contacts are needed for signal integrity below 100 mΩ contact resistance across the product lifetime.
