What are the key features of TST-102-01-L-D?
- 4-position dual-row shrouded design with 0.100" (2.54 mm) pitch prevents connector mis-mating and protects square pins
- Right-angle (L) orientation suits low-profile PCB assemblies where vertical clearance is limited to a few millimeters
- Gold (10 µin) over nickel mating contact finish provides reliable low-resistance connections across many mating cycles
- Square-pin contact style with tin-over-nickel termination ensures strong solder joints and consistent PCB attachment
- Compact 0.5 inch body length with 0.365 inch breadth and depth enables dense connector placement in small form-factor boards
What is TST-102-01-L-D used for?
The SAMTEC TST-102-01-L-D is used in industrial sensors, embedded controller boards, and consumer electronics where a 4-position right-angle shrouded header is needed in a constrained vertical footprint. The right-angle (L) mounting allows PCB-edge accessible cabling while maintaining a low-profile assembly suitable for enclosure-mounted designs. Its 2.54 mm pitch aligns with standard ribbon cables and IDC connectors, making it easy to integrate into existing harness and board designs across prototyping and production environments.

Frequently Asked Questions
How does the right-angle orientation of the TST-102-01-L-D affect PCB layout and connector accessibility?
The right-angle (L suffix) orientation of the TST-102-01-L-D positions the mating direction parallel to the PCB surface, reducing the vertical height requirement compared to vertical headers and making the connector accessible from the board edge. This is useful in low-profile enclosures where a vertical 0.100" header would protrude too far, and it allows the 4-position connector body (0.5 inch long, 0.365 inch deep) to fit within standard chassis cutouts without modifying the enclosure.
What contact finish is used on the TST-102-01-L-D and how does it compare to higher gold thickness variants?
The TST-102-01-L-D uses 10 µin gold over nickel on the mating contacts, which suits applications with moderate mating cycle counts in clean environments. Variants with 30 µin gold over nickel provide longer durability for applications exceeding several hundred mating cycles or operating in more corrosive conditions. Both variants share the same 4-position, 0.100" pitch dual-row shrouded form factor, so specifying the higher gold thickness requires only a part number change with no PCB layout modification.
Which embedded or industrial applications commonly use the 4-position SAMTEC TST-102-01-L-D connector?
Industrial I/O modules, UART and SPI debug headers, and sensor-to-microcontroller wiring harnesses frequently use the TST-102-01-L-D because 4 positions cover common 2-wire, 3-wire, and 4-wire signal groups at 0.100" pitch. The shrouded body prevents accidental reversal in field-service environments, and the right-angle mounting suits panel-mount connectors in PLCs, data loggers, and embedded gateway products where the PCB sits horizontally inside an enclosure.
How does the TST-102-01-L-D body size affect PCB keep-out planning for dense board layouts?
The TST-102-01-L-D body measures 0.5 inch in length, 0.365 inch in breadth, and 0.365 inch in depth, requiring a keep-out zone of at least those dimensions plus the mating connector overhang in the right-angle direction. On a dense 2-layer PCB, placing the connector near the board edge with a 5 mm clearance to adjacent components typically satisfies both the shroud depth and the required mating clearance for standard 4-position 2.54 mm pitch mating connectors.
