What are the key features of TST-107-05-H-D?
- 14-position dual-row shrouded header at 2.54 mm pitch with polarized housing for error-proof mating in field-wired applications
- High-profile (H) shroud provides deep socket engagement and enhanced mechanical retention for connectors subject to vibration and cable pull
- Gold-over-nickel mating contact finish ensures low contact resistance below 30 mΩ across hundreds of connect and disconnect cycles
- Through-hole square-pin contacts compatible with IDC ribbon cable sockets and SAMTEC TST/SSW socket families for broad second-source flexibility
- Rated approximately 3 A per pin at 250 V AC insulation, suitable for mixed power and signal allocations across 14 circuits
What is TST-107-05-H-D used for?
The TST-107-05-H-D is suited for board-to-wire and board-to-board interconnects in industrial control panels, embedded computing modules, and laboratory test fixtures where a 14-circuit 2.54 mm pitch shrouded header provides both circuit density and misinsertion protection. The high-profile shroud ensures secure cable retention in equipment that experiences frequent connector mate and unmate cycles during maintenance or reconfiguration. It is also widely used in development boards and evaluation kits as the primary expansion connector for GPIO, JTAG, or peripheral bus interfaces.

Frequently Asked Questions
How many circuits does the TST-107-05-H-D provide and in what physical arrangement?
The TST-107-05-H-D has 14 positions arranged in 2 rows of 7 contacts at a 2.54 mm (0.100 inch) pitch. This 7×2 dual-row format matches the footprint of standard 14-pin IDC ribbon cable assemblies, making it directly compatible with off-the-shelf flat-flex cable harnesses used in development and production wiring.
What does the H suffix mean in TST-107-05-H-D and how does it benefit rugged applications?
The H suffix designates the high-profile shroud variant, which extends the plastic housing walls further above the contact pins than the standard-profile version. This deeper shroud wall provides approximately 2 mm to 3 mm more engagement depth for the mating socket, reducing the chance of partial disengagement under cable tension or mechanical shock loads exceeding 10 g, common in transportation and industrial machinery.
What per-pin current and voltage can the TST-107-05-H-D handle in a mixed power and signal design?
SAMTEC TST-series 2.54 mm pitch contacts carry approximately 3 A per pin at rated insulation voltage of 250 V AC. In a 14-pin mixed-use application, a designer could assign 4 pins to a 12 V power rail delivering up to 12 A combined, while routing differential UART, I2C, and SPI signals on the remaining 10 pins — all within a single polarized connector that cannot be reversed.
Which mating connector families are compatible with the TST-107-05-H-D?
The TST-107-05-H-D mates with SAMTEC SSW, SNT, and TST dual-row socket strips at 2.54 mm pitch in a 7-column by 2-row pattern, as well as standard 14-pin IDC sockets from multiple manufacturers. The 14-pin layout is also compatible with many JTAG and ARM Cortex debug ribbon cable connectors, making this header a common choice for embedded debug port interfaces.
For a prototype development board, how does TST-107-05-H-D compare to an unshielded 14-pin header for GPIO expansion?
Unlike a bare 2×7 pin header without a shroud, the TST-107-05-H-D's polarized shroud prevents reversed ribbon cable insertion, which can damage 3.3 V or 5 V logic devices in seconds. The gold mating contact finish also maintains stable contact resistance below 30 mΩ through repeated prototyping connect-disconnect cycles, whereas tin-plated unshrouded headers can develop oxide buildup that raises resistance above 100 mΩ after only 50 cycles.
