What are the key features of TST-103-05-S-D?
- 0.100 inch (2.54 mm) pitch dual-row shrouded header with 6 positions for compact board-to-wire interconnects
- Polarizing shroud prevents mis-mating and ensures correct orientation during cable assembly installation
- Compatible with standard IDC ribbon cable and crimp-style connectors for versatile wiring configurations
- Robust PCB through-hole termination provides high mechanical retention force for vibration-prone environments
What is TST-103-05-S-D used for?
The TST-103-05-S-D is commonly used in embedded systems, industrial control panels, and test equipment for routing digital I/O, SPI, UART, or power signals between PCBs and external wire harnesses. Its shrouded design is favored in robotics, motor drives, and sensor interface boards where accidental mis-connection could damage circuitry. The 0.100 inch pitch makes it universally compatible with standard development board cable sets and ribbon cable looms.

Frequently Asked Questions
What pitch and position count does TST-103-05-S-D use, and what cable types is it compatible with?
The TST-103-05-S-D uses a 0.100 inch (2.54 mm) pitch with 6 positions arranged in dual rows, totaling 6 contacts. It is compatible with standard 0.100 inch IDC ribbon cable assemblies and 2.54 mm crimp-style wire-to-board harnesses, which are among the most widely available connector accessories in electronics manufacturing.
How does the polarizing shroud on the TST-103-05-S-D help prevent field wiring errors in industrial installations?
The shroud on the TST-103-05-S-D provides physical keying that permits mating in only one orientation, eliminating the risk of reversing a 6-pin cable on a 2.54 mm pitch header. This is critical in industrial motor drives and sensor nodes where a reversed power or signal connection at even 5 V or 12 V supply rails can destroy components during field maintenance.
What current and voltage ratings are typical for SAMTEC TST-series headers at 0.100 inch pitch?
SAMTEC TST-series 0.100 inch pitch headers are typically rated for up to 3 A per contact and 250 V AC/DC working voltage, with contact resistance below 20 mΩ. These ratings support both logic-level signal routing at 3.3 V or 5 V and moderate power distribution duties in 12 V or 24 V industrial wiring applications.
Can TST-103-05-S-D be used for JTAG or SWD debug headers on embedded development boards?
Yes. The 6-position, 0.100 inch dual-row format of TST-103-05-S-D matches standard JTAG and SWD debug cable footprints used on ARM Cortex-M and FPGA development boards. Debuggers such as J-Link and CMSIS-DAP adapters with a 0.100 inch 10-pin or 6-pin ribbon cable plug directly into this shrouded header, providing a secure, polarized connection for programming and debug sessions.
How does TST-103-05-S-D compare to unshrouded 2.54 mm pin headers for prototype board wiring?
Unlike unshrouded 2.54 mm pin headers, the TST-103-05-S-D shroud provides a defined mating envelope that aligns and locks IDC or crimp connectors in 6 positions, reducing accidental disconnection during board handling. The shroud adds approximately 3 mm to 4 mm of height above the PCB surface but greatly improves reliability in vibrating environments where bare pins can work loose from unseated female connectors.
