What are the key features of TST-107-04-T-D?
- 14 positions (2×7) dual-row layout on 0.100" (2.54 mm) pitch for compact board-to-board connectivity
- Polarized shroud prevents mis-mating and protects contacts during repeated assembly cycles
- Through-hole solder termination provides strong mechanical retention on PCBs subject to vibration
- Gold-plated contacts ensure low contact resistance and long-term reliability for signal-level connections
- Compatible with Samtec TST series mating receptacles for a complete, tested connector system
What is TST-107-04-T-D used for?
The TST-107-04-T-D is commonly used for board-to-board and wire-to-board connections in embedded computing, industrial control modules, and test and measurement equipment. Its 14-position dual-row layout on the widely adopted 0.100" grid makes it straightforward to integrate with standard ribbon cables and SIL/DIL connectors. The shrouded design is particularly valuable in rack-mounted or cable-dense environments where accidental mis-insertion must be prevented.

Frequently Asked Questions
How many circuits does the TST-107-04-T-D provide and what is the contact pitch?
The TST-107-04-T-D offers 14 circuits arranged in a 2×7 dual-row configuration on a 0.100" (2.54 mm) pitch. This standard grid spacing ensures compatibility with common ribbon cables, IDC connectors, and 0.100" PCB footprints used throughout embedded and industrial designs.
What current and voltage ratings should designers expect from the TST-107-04-T-D in a power distribution application?
Samtec TST series headers are typically rated for 3 A per contact and 250 V AC/DC, though designers should derate to 1–2 A per pin in multi-circuit power distribution to stay within PCB trace and contact thermal limits. The gold-plated contacts maintain low resistance, supporting reliable low-power supply rails in embedded boards.
How does the shroud on TST-107-04-T-D reduce assembly errors on high-density backplanes?
The polarized shroud physically blocks insertion of a mating connector in the wrong orientation, eliminating a common source of field failures on backplanes with 14-pin or wider headers arranged in close proximity. This keying feature is especially valuable in production environments where 2.54 mm pitch headers look similar and mis-mating could damage 3.3 V or 5 V logic circuits.
Which Samtec mating receptacle is designed to mate with TST-107-04-T-D?
The TST-107-04-T-D mates with Samtec's TSW series receptacles on a 0.100" (2.54 mm) pitch grid. The dual-row 14-pin mating pair provides a 28-circuit interconnect path, supporting both signal and low-current power lines with a tested mating cycle rating of typically 30 cycles or more.
