What are the key features of TST-103-02-F-D?
- 6-position dual-row layout on 0.100" (2.54 mm) pitch fits the universal IDC ribbon cable standard for straightforward cable harness mating
- Polarized protective shroud prevents mis-insertion and provides mechanical support for the mated connector during vibration
- Gold flash over nickel contact finish on the mating surface ensures low contact resistance and resistance to oxidation over thousands of mating cycles
- Tin-over-nickel termination finish on the solder tails is compatible with standard reflow and wave soldering lead-free solder processes
- Compact 0.6 inch body length accommodates tight PCB placement zones while providing a secure 6-pin interconnect interface
What is TST-103-02-F-D used for?
The TST-103-02-F-D is widely used on development boards, evaluation kits, and production PCBs where a small 6-pin polarized header is required for programming interfaces, JTAG/SWD debug connectors, or low-density I/O expansion ports. Its shrouded dual-row design is a standard choice for connecting 6-wire ribbon cable assemblies to microcontroller boards, power modules, and sensor interface cards in industrial automation systems and embedded computing applications. The gold flash mating contacts also make this connector suitable for test fixture jigs where repeated insertion and removal of ribbon cable assemblies is required over the product development cycle.

Frequently Asked Questions
What pin pitch and total position count does the TST-103-02-F-D provide, and what cable types does it mate with?
The TST-103-02-F-D provides 6 positions on a 0.100" (2.54 mm) pitch in a dual-row arrangement with 3 pins per row, mating with standard 6-pin IDC ribbon cable connectors, individual female-to-female jumper wires, or custom crimp cable assemblies designed for the 2.54 mm grid. This universal 0.100" pitch makes it compatible with the widest range of off-the-shelf cable accessories available from major connector distributors worldwide.
What contact finish does the TST-103-02-F-D use on its mating surface, and how does this compare to bare tin contacts?
The TST-103-02-F-D uses gold flash (3 microinches, approximately 0.076 µm) over nickel on the mating surface contacts, providing significantly lower and more stable contact resistance than bare tin contacts, which can oxidize and form tin whiskers over time. Gold flash finish maintains contact resistance below 30 mΩ throughout the rated mating cycle life, making it preferable to bare tin for applications with infrequent mating cycles where oxide-free surface integrity over months or years of service is important.
How does the shroud on the TST-103-02-F-D protect against mis-mating, and in what applications is this critical?
The TST-103-02-F-D shroud surrounds all 6 male pins with a polarized housing that guides the mating connector into the correct orientation, physically preventing 180-degree reversed insertion that would connect pin 1 to pin 6 and potentially damage connected circuits. This polarization is critical in programming and debug applications, such as SWD or JTAG interfaces on embedded microcontroller boards, where reversed connection of a programming header can apply supply voltage to ground pins and damage the target device or programmer.
What are the body dimensions of the TST-103-02-F-D, and how much PCB space is required to place it with adequate clearance?
The TST-103-02-F-D body measures 0.6 inch (15.24 mm) in length and 0.365 inch (9.27 mm) in both breadth and depth, requiring a PCB landing area of approximately 18 mm × 12 mm including the recommended 1 mm clearance on all sides for adjacent component placement and mating connector access. The 0.365 inch body depth also determines the connector height above the PCB surface, which must be accounted for when specifying enclosure clearance and cable routing above the PCB.
Is the TST-103-02-F-D suitable for automated pick-and-place assembly, and what solder process is compatible?
The TST-103-02-F-D through-hole male header is compatible with both wave soldering and selective soldering processes commonly used for through-hole components in automated PCB assembly. The tin-over-nickel solder tail finish accepts standard SAC305 (96.5% Sn, 3% Ag, 0.5% Cu) lead-free solder at peak reflow temperatures of 260°C, and the housing material is rated to withstand wave solder bath temperatures of approximately 260°C for 5 seconds without deformation.
