What are the key features of TST-103-01-H-D?
- 6-position dual-row layout on 0.100 inch (2.54 mm) pitch fits standard IDC ribbon and discrete wire harnesses
- 30 µin gold over nickel contact finish delivers low contact resistance and extended mating cycle life
- Shrouded housing provides polarity keying and protects square-pin contacts during cable mating
- 0.6 inch body length with 0.365 inch depth suits standard through-hole PCB layouts
- Samtec quality construction ensures consistent 6 contact positions across high-volume production runs
What is TST-103-01-H-D used for?
The TST-103-01-H-D is widely used on development boards, test fixtures, and industrial control panels where a polarized 6-pin dual-row header is needed to connect ribbon cables or discrete wire harnesses with 0.100" pitch terminations. Its shrouded housing prevents mis-keying in field-installed cable assemblies, making it a reliable choice for power distribution, signal bussing, and JTAG/debug port connections in embedded systems. The gold contact finish also makes it suitable for low-level signal interfaces where contact resistance stability over thousands of mating cycles is required.

Frequently Asked Questions
What pin pitch and row configuration does the TST-103-01-H-D use?
The TST-103-01-H-D uses a 0.100 inch (2.54 mm) pitch in a dual-row configuration with 3 positions per row, giving 6 contacts total. This is the industry-standard through-hole pitch compatible with the majority of IDC ribbon cable connectors and discrete wire sockets, simplifying sourcing of mating parts. The body measures 0.6 inch in length and 0.365 inch in depth.
What contact finish does TST-103-01-H-D use, and how does it affect mating reliability?
The TST-103-01-H-D features 30 µin (microinches) gold plating over a nickel underplate on its mating contacts. Gold at this thickness provides low and stable contact resistance, typically below 20 milliohms, and supports hundreds of mating cycles without significant oxidation or wear. This makes it suitable for both frequent re-mating in test fixtures and long-term static connections in production assemblies.
Can the TST-103-01-H-D be used for a JTAG debug port on a production board?
Yes, the TST-103-01-H-D is a practical choice for a 6-pin JTAG or SWD debug header. Its shrouded housing ensures the debug cable is inserted in the correct orientation, preventing pin damage during programming. The 0.100 inch pitch is standard for most ARM and PIC debug probes, and the 30 µin gold contacts maintain signal integrity on the TCK, TMS, TDI, TDO, GND, and VCC lines even after repeated probe connections.
How does the shrouded design of TST-103-01-H-D compare to unshrouded alternatives in field-installed assemblies?
The shrouded housing mechanically guides the mating connector into the correct 6-position alignment and prevents insertion of a 2×3 cable housing rotated 180 degrees, which would reverse polarity and risk damaging connected circuitry. Unshrouded headers offer lower profile but leave all pins exposed to accidental short circuits during cable installation in the field. For any application where non-technical personnel will connect cables, the shrouded TST-103-01-H-D reduces the risk of board damage.
What are the body dimensions of TST-103-01-H-D, and does it fit standard 0.1-inch grid PCB footprints?
The TST-103-01-H-D has a body length of 0.6 inch, a body breadth of 0.365 inch, and a body depth of 0.365 inch. The 6 pins are arranged in a 2×3 grid on the 0.100 inch standard grid, so the footprint is directly compatible with most PCB CAD libraries that include generic 2×3 100-mil headers. Pad-to-pad spacing follows the 2.54 mm grid, enabling straightforward layout on standard FR4 PCBs.
