What are the key features of TST-104-03-H-D?
- 8-position (2×4) dual-row layout on 2.54 mm (0.100 inch) pitch for compact 8-circuit PCB header
- 30 µin gold contact finish over nickel for low contact resistance and extended mating cycle life up to 50 cycles
- Polarized shroud prevents incorrect cable or daughterboard orientation during assembly and field service
- Square-pin contact style accepts standard 2.54 mm socket housings and IDC ribbon connectors
- 0.700 inch total body length provides mechanical clearance for shroud engagement with standard 2.54 mm pitch socket connectors
What is TST-104-03-H-D used for?
The TST-104-03-H-D is used on motherboards, development kits, and industrial control PCBs where an 8-position, 2.54 mm pitch shrouded header is needed for ribbon cable or daughter card interconnection. The 30 µin gold contacts ensure reliable low-resistance connections in test fixtures and removable panel interfaces that are mated and unmated frequently. Its dual-row layout in a compact 0.365 inch × 0.700 inch footprint suits dense I/O headers on embedded single-board computers and FPGA evaluation boards.

Frequently Asked Questions
Why does the TST-104-03-H-D use 30 µin gold plating over nickel instead of tin for its contacts?
The 30 µin gold-over-nickel contact finish provides lower and more stable contact resistance than tin plating, especially through repeated mating cycles. Gold does not form an insulating oxide layer the way tin does under humidity or elevated temperature, making the TST-104-03-H-D suitable for test fixtures or removable daughter boards that are mated and unmated dozens of times without degrading the sub-50 mΩ contact resistance needed for signal integrity.
How does the shroud on the TST-104-03-H-D protect circuits on a densely populated PCB during ribbon cable attachment?
The molded shroud surrounding all 8 pins guides a 2.54 mm pitch 8-way socket or IDC ribbon plug into exact alignment, preventing the common failure mode of a 2×4 plug being inserted one row or one column off-center. This is critical on boards where adjacent headers carry different voltage rails such as 3.3V and 12V or mixed signal and power pins, where a single mismated 8-pin header can short supply rails and damage ICs.
Can the TST-104-03-H-D mate directly with standard 0.100 inch pitch IDC ribbon cable assemblies?
Yes. The TST-104-03-H-D has 2.54 mm (0.100 inch) pitch square-pin male contacts in a 2×4 dual-row arrangement, which is the standard footprint for 8-way IDC ribbon cable connectors commonly used in embedded computing and industrial I/O cabling. The 0.365 inch body width and shrouded guide ensure reliable engagement with both insulation-displacement and socket-crimp cable housings using the standard 8-circuit 2.54 mm pitch form factor.
