What are the key features of TST-103-01-L-D?

  • 3-position single-row straight PTH box header with shrouded design for polarized mating protection
  • Gold (10µin) over nickel mating contacts ensure low contact resistance and durability through multiple mating cycles
  • Tin-nickel barrier termination finish provides excellent solderability for through-hole PCB assembly
  • Rectangular contact pattern with 0.6 inch body length suits compact board-to-board connector applications

What is TST-103-01-L-D used for?

The TST-103-01-L-D is ideal for low-pin-count board-to-board or wire-to-board connections in industrial controls, consumer electronics, and embedded computing platforms. Its 3-position shrouded design prevents mis-mating in field-assembled systems where connector orientation must be maintained. Design engineers frequently specify this connector in power supply, sensor interface, and communication modules requiring durable, polarized interconnects.

Frequently Asked Questions

How many positions does the TST-103-01-L-D have and what is its contact finish?

The TST-103-01-L-D is a 3-position single-row connector featuring gold (10 microinch) over nickel mating contacts and a tin-nickel barrier termination. This combination provides low contact resistance suitable for signal lines up to several amps, and the gold finish ensures reliability through repeated mating cycles in industrial or field-service applications.

What PCB assembly method is the TST-103-01-L-D designed for and what are its body dimensions?

The TST-103-01-L-D uses through-hole (PTH) assembly, making it compatible with wave soldering and hand soldering processes. The body measures 0.6 inch in length, 0.365 inch in breadth, and 0.365 inch in depth, providing a compact footprint with a shrouded straight orientation that locks mating connectors securely onto the PCB.

Why choose a shrouded box header like the TST-103-01-L-D over an open pin header in field-assembled equipment?

Shrouded box headers like the TST-103-01-L-D include a polarizing key that prevents reverse or offset mating during field assembly, reducing risk of damaged pins or circuit faults. The 3-position single-row configuration with gold-over-nickel contacts rated for multiple mating cycles also outperforms open pin headers in vibration-prone environments such as industrial controllers, where connector retention of at least 30N extraction force is critical.

What is the typical lead time for the TST-103-01-L-D when ordering from SAMTEC?

According to SAMTEC specifications, the factory lead time for the TST-103-01-L-D is approximately 2 weeks and 6 days. Distributors with stock on hand can ship same-day or next-day for small quantities, making this 3-position shrouded PTH connector accessible for both prototyping runs and higher-volume production orders with worldwide shipping options.
