What are the key features of TST-106-05-G-D?
- 12-position dual-row shrouded header at 0.100" (2.54 mm) pitch with polarization key to prevent mismated connections
- Gold-plated contacts maintain contact resistance below 20 mΩ for reliable signal integrity across hundreds of mating cycles
- Through-hole mounting with press-fit tails enables robust mechanical retention on single-layer and multilayer PCBs during vibration
What is TST-106-05-G-D used for?
The TST-106-05-G-D is widely used in prototyping boards, embedded system backplanes, and test fixtures where 12 signals must be routed between boards or ribbon cables using the standard 0.100" pitch. Its dual-row shrouded design with polarization is valued in industrial control panels, laboratory instruments, and automotive test benches to prevent incorrect cable insertion during repeated connect/disconnect maintenance cycles. Educational development kits and microcontroller breakout boards also use this header type for robust GPIO expansion connections.

Frequently Asked Questions
How many contact positions does the TST-106-05-G-D provide, and what row configuration does it use?
The TST-106-05-G-D provides 12 total contact positions in a dual-row arrangement, giving 6 contacts per row at a 0.100" (2.54 mm) pitch. The shrouded housing adds a plastic polarization key that prevents 180-degree mismating when connecting a ribbon cable or matching IDC socket.
What mounting style does the TST-106-05-G-D use, and how does through-hole mounting compare to SMT for vibration resistance?
The TST-106-05-G-D uses through-hole mounting with solder tails that pass through the PCB and are wave- or hand-soldered on the underside. Through-hole solder joints have a much larger cross-section than SMT pads, providing 3–5× higher pull-out force, which is why through-hole headers are preferred in vibrating environments such as automotive test rigs and industrial machinery.
Can the TST-106-05-G-D be used with standard IDC ribbon cable assemblies and 2×6 IDC sockets?
Yes, the TST-106-05-G-D is dimensionally compatible with standard 2×6, 0.100" pitch IDC ribbon cable connectors and sockets. The 0.100" (2.54 mm) dual-row pitch matches the universal IDC standard, so off-the-shelf 12-conductor ribbon cables with mass-displacement connectors will mate directly with the header's 12 positions.
For a PCB design that needs to survive 500 connect/disconnect maintenance cycles, does the TST-106-05-G-D qualify?
SAMTEC TST series shrouded headers are rated for a minimum of 50 mating cycles under standard conditions, but gold-plated contact variants maintain contact resistance below 20 mΩ well beyond that figure in clean environments. For 500 cycles in a harsh industrial setting, designers often specify a heavier gold plating thickness of 30 µin (0.76 µm) on special order, or evaluate the SAMTEC ESQ socket series which is rated for higher cycle counts.
