What are the key features of TST-114-03-G-D?
- 28-position dual-row shrouded male PCB header with 0.100" (2.54 mm) pitch and 1.7 inch body length for robust board-to-board signal connectivity
- Gold (10 µin) over nickel (50 µin) mating contact finish on phosphor bronze base delivering low contact resistance, high spring force, and corrosion resistance over thousands of mating cycles
- Polarized shroud body prevents mis-orientation during mating, protecting all 28 contacts during field servicing and automated assembly
What is TST-114-03-G-D used for?
The TST-114-03-G-D is designed for industrial controllers, communications backplanes, and embedded computing systems that require reliable 28-pin dual-row interconnects with 0.100" pitch and high mating-cycle durability. The gold-plated phosphor bronze contacts make it suitable for test and measurement equipment and mil-aero applications where connector reliability under mechanical shock and thermal stress is critical. Its shrouded design ensures correct connector orientation during assembly, reducing field service errors in rack-mounted systems.

Frequently Asked Questions
What contact material and plating stack does TST-114-03-G-D use for its mating contacts?
TST-114-03-G-D uses phosphor bronze contacts plated with 50 µin nickel barrier and 10 µin gold on the mating surface. Phosphor bronze provides excellent spring-back after repeated deflection, while the gold finish keeps contact resistance below 20 milliohms across all 28 positions over thousands of mating cycles.
Which industrial or defense applications suit the shrouded design of the TST-114-03-G-D?
The shrouded 28-position body of TST-114-03-G-D is well-suited for VMEbus backplane systems, avionics mission computers, and industrial motor drive control boards where mis-mating a 0.100" pitch connector could cause catastrophic circuit damage. The polarized shroud ensures correct insertion orientation even in low-light or high-vibration field environments.
How does the 28-position count of TST-114-03-G-D compare to the 22-position TST-111 variant for bus expansion needs?
TST-114-03-G-D offers 28 positions versus the 22 positions of the TST-111 series, providing 6 additional signal lines within the same 0.100" pitch dual-row format. The extra contacts support wider data buses such as 24-bit parallel interfaces or combined power-plus-signal configurations, while the body length increases from 1.4 inch to 1.7 inch to accommodate the 3 additional column pairs.
