What are the key features of TST-103-04-T-D?
- 6-position dual-row shrouded header with 2.54 mm (0.100") pitch for reliable board-to-board connections
- Polarizing shroud prevents mis-mating and protects contact pins during cable assembly
- Through-hole tail termination provides strong mechanical retention with solder joint integrity
- Dual-row 3x2 configuration maximises contact density in minimal PCB area
What is TST-103-04-T-D used for?
TST-103-04-T-D is commonly used in embedded systems and industrial control boards where a keyed, shrouded interface protects against incorrect cable insertion during field servicing. Its 2.54 mm pitch and dual-row layout suit ribbon-cable and flat-flex assemblies in robotics, instrumentation, and power management modules. The through-hole mounting style also provides enhanced mechanical strength in vibration-prone environments.

Frequently Asked Questions
What current and voltage ratings apply to the TST-103-04-T-D shrouded header?
The TST-103-04-T-D supports up to 1 A per contact at voltages up to 250 V AC/DC, with contact resistance typically below 20 mΩ, making it suitable for low-power signal and auxiliary power distribution in embedded and industrial PCB designs.
How does the polarizing shroud on the TST-103-04-T-D reduce assembly errors in production environments?
The polarizing shroud physically blocks insertion of a mating plug in the wrong orientation, reducing mis-mating errors to near zero; combined with the 2.54 mm pitch dual-row layout, this ensures consistent contact alignment across all 6 pins during automated cable-assembly and field-service operations.
Which mating connectors are compatible with the TST-103-04-T-D on a 2.54 mm pitch dual-row header?
The TST-103-04-T-D mates with Samtec's FTM, HTST, or compatible IDC ribbon-cable sockets on a 2.54 mm (0.100 inch) dual-row pitch; standard 6-pin (2×3) IDC connectors from other vendors sharing the same pitch and row spacing also mate correctly, giving broad cable-assembly sourcing flexibility.
For what operating temperature range is the TST-103-04-T-D rated, and how does that affect industrial use cases?
The TST-103-04-T-D is rated from -55 °C to +125 °C, which covers most industrial and automotive control-board environments; the high upper limit allows it to survive near power-dissipating components or in enclosed enclosures without derating the 1 A per-contact current specification.
