What are the key features of TST-103-02-T-D?
- 6-position dual-row shrouded header at 0.100" (2.54 mm) pitch for compact, standard-density board interconnects
- Tin (200 µin) over nickel mating contacts providing corrosion resistance and reliable low-force mating across hundreds of cycles
- Tin over nickel barrier termination contacts compatible with lead-free reflow soldering at up to 260°C
- Shrouded housing with rectangular pin-socket pattern prevents connector mis-insertion and protects contacts during repeated mating
What is TST-103-02-T-D used for?
The TST-103-02-T-D is used in embedded controller boards, development platforms, and test fixtures where a 6-pin shrouded interface is needed to connect ribbon cables, jumper wires, or pre-terminated cable assemblies at the 0.100" standard pitch. Its dual-row layout allows 6 signal or power lines to be routed through a compact 0.6 inch body length connector on space-constrained PCBs. The shrouded design and square-pin contacts make it a natural choice for Arduino-compatible shields, STM32 Nucleo board expansions, and industrial sensor interface boards requiring keyed polarization.

Frequently Asked Questions
How many positions and rows does the TST-103-02-T-D provide, and what is its contact pitch?
The TST-103-02-T-D provides 6 total positions arranged in a dual-row rectangular pattern at 0.100" (2.54 mm) pitch, with 3 positions per row. This configuration allows 6 signal or power lines to be routed through a single compact connector with a 0.6 inch body length, fitting standard PCB grid spacing used in Arduino, Raspberry Pi, and embedded development boards worldwide.
What mating contact finish does the TST-103-02-T-D specify, and how does it affect connector longevity?
The TST-103-02-T-D uses tin (200 µin) over nickel on its mating contacts. The heavy 200 µin tin plating provides significantly better wear resistance than thin tin or bare-nickel alternatives, extending the usable mating cycle life and maintaining low contact resistance for reliable signal continuity across hundreds of insertion and removal cycles in lab, production, and field environments.
In which PCB application scenarios does the shrouded housing of the TST-103-02-T-D add value over unshrouded headers?
The shrouded housing on the TST-103-02-T-D physically guides mating cable assemblies into correct alignment, preventing the 1-pin offset mis-mating that can damage circuits on unshrouded headers. This is especially valuable in production assembly lines, field service operations, and test fixtures where operators must quickly mate and de-mate 6-pin connectors under time pressure, reducing the risk of reversed-polarity or offset-pin damage to sensitive embedded logic at 3.3 V or 5 V supply rails.
When would a designer choose the TST-103-02-T-D over a screw-terminal block for a 6-signal board connection?
Engineers choose the TST-103-02-T-D over screw terminals when repeated quick-connect and disconnect of a 6-line cable harness is required without tools, or when PCB board space limits the footprint to a 0.6 inch connector length. Screw terminals require a minimum pitch of 3.5 mm to 5.08 mm per position, consuming over twice the PCB area for the same 6 circuits that the 0.100" pitch TST-103-02-T-D covers, making the shrouded header the clear choice for compact embedded and consumer electronics designs.
