What are the key features of TST-103-03-T-D?
- 6-position dual-row shrouded PCB header with 0.100" (2.54 mm) pitch for compact, high-density board-to-board interconnects
- Tin (Sn) over Nickel (Ni) contact finish on both mating and termination sides ensures low contact resistance and corrosion resistance
- Shrouded housing provides polarization and mechanical protection, preventing mis-mating in automated assembly environments
- Rectangular sq pin-socket contact pattern compatible with standard 2.54 mm grid PCB layouts and a wide range of mating sockets
What is TST-103-03-T-D used for?
TST-103-03-T-D is widely used in industrial control boards, embedded development platforms, and test-and-measurement instruments that require reliable 6-position dual-row interconnects at 0.100" pitch. Its shrouded, polarized housing makes it suitable for backplane and daughtercard assemblies where accidental mis-insertion must be prevented. The through-hole solder termination delivers robust mechanical retention in high-vibration environments such as robotics and automotive test rigs.

Frequently Asked Questions
What is the contact pitch and row configuration of the TST-103-03-T-D connector?
TST-103-03-T-D is a dual-row, 6-position shrouded PCB header with a 0.100" (2.54 mm) pitch. It has 3 positions per row, giving a total of 6 contacts arranged in the standard rectangular sq pin-socket pattern compatible with 2.54 mm grid PCBs.
Which PCB assembly environments benefit most from the shrouded housing of the TST-103-03-T-D?
The polarized shrouded housing on TST-103-03-T-D prevents mis-mating during automated SMT or through-hole assembly, making it ideal for industrial control boards, backplane systems, and daughtercard assemblies where 6-position dual-row connectors are repeatedly inserted and removed. The shroud adds mechanical protection that is especially valuable in high-vibration environments operating across temperature ranges typical of -40°C to +85°C industrial service.
How does the tin-over-nickel contact finish on the TST-103-03-T-D affect long-term reliability?
Both the mating and termination contacts use Tin (Sn) with a Nickel (Ni) barrier, a finish that provides at least 200 micro-inches of tin plating. This combination yields low contact resistance, strong corrosion resistance, and compatibility with standard tin-based solder processes, extending connector service life in environments with moderate humidity and temperature cycling up to 85°C.
When should a designer choose TST-103-03-T-D over an unshrouded 6-position header for a motor-control PCB?
For motor-control PCBs that experience vibration amplitudes above 5 G or require frequent field connector swaps, TST-103-03-T-D's shrouded housing offers polarization and mechanical keying that unshrouded headers lack. The shroud reduces the risk of accidental 180-degree mis-mating, which can damage ICs or sensors connected to the 6 pins, especially in 24 V or 48 V powered control rails.
