What are the key features of TST-103-05-G-D?
- 6-position dual-row 2.54 mm pitch shrouded header with polarization key prevents mis-mating in cable-to-board connections
- Gold-plated contacts (G suffix) deliver low contact resistance below 20 mΩ and support 100+ mating cycles
- 3 A per-pin current rating supports mixed signal-and-power applications in compact PCB connectors
What is TST-103-05-G-D used for?
The TST-103-05-G-D is used in embedded controller boards, sensor node PCBs, and robotics modules where a compact 6-position dual-row shrouded header with 2.54 mm pitch provides mistake-proof cable-to-board connectivity for signal and low-power supply lines. It is also widely used in prototyping and laboratory bench setups where gold contacts and a shroud ensure reliable mating during repeated connect-disconnect cycles across -55°C to 125°C operating temperatures.

Frequently Asked Questions
How many positions and rows does the TST-103-05-G-D connector provide?
The TST-103-05-G-D provides 6 positions in a dual-row (2×3) arrangement with 2.54 mm (0.100 inch) pitch, giving 3 pins per row, which is a standard layout compatible with most 6-pin cable-mate IDC and discrete wire assemblies used in embedded and robotics applications.
How does gold plating on TST-103-05-G-D benefit high-cycle mating scenarios?
The gold-plated contacts (G suffix) maintain contact resistance below 20 mΩ and provide corrosion resistance across more than 100 mating cycles, which is essential for test fixtures, programming jigs, and debug cables that connect and disconnect dozens of times per day at currents up to 3 A per pin.
Can TST-103-05-G-D prevent incorrect cable orientation during field assembly?
Yes, the shrouded housing includes a polarization key that physically blocks reversed or offset cable-mate insertion across all 6 pins, reducing wiring errors in production environments and ensuring correct signal assignment when technicians assemble cables by hand without referencing a wiring diagram for each connector.
What current and temperature limits apply to TST-103-05-G-D in a sensor power distribution application?
Each pin is rated at 3 A continuous, and the housing material is rated for -55°C to 125°C operation, so a 6-position header can distribute up to 18 A total (3 A × 6 pins) for power-sharing configurations, or serve as a mixed signal-and-power connector where some pins carry 5 V or 3.3 V supply rails alongside sensor data lines.
