What are the key features of TST-112-03-G-D?
- 24-position dual-row shrouded header on 0.100" (2.54 mm) pitch with 1.5-inch body length for robust board-to-board connections
- 10 µin gold over 50 µin nickel mating finish on phosphor-bronze contacts for reliable low-contact-resistance mating
- Gold over nickel termination finish ensures excellent solderability to PCB pads in both wave and reflow assembly processes
What is TST-112-03-G-D used for?
The TST-112-03-G-D is designed for reliable board-to-board and board-to-cable interconnect in industrial control, embedded computing, and test instrumentation. The shrouded housing on the 24-position dual-row header prevents contact damage and misalignment during repeated field mating, which is important for modular systems where plug-in cards are swapped during maintenance. Gold termination and phosphor-bronze contacts also ensure this connector maintains consistent electrical performance across the full industrial temperature range.

Frequently Asked Questions
How does the gold termination finish on the TST-112-03-G-D differ from a matte tin termination, and which PCB assembly process benefits most?
The TST-112-03-G-D uses gold over nickel on both the mating surfaces and PCB termination pins, unlike matte tin versions that use tin only at the solder interface. Gold termination is preferred for selective soldering and rework processes where multiple heat cycles are expected, since gold maintains solderability longer than tin-oxide-prone matte tin finishes, particularly in humid storage conditions before assembly.
What body dimensions does the TST-112-03-G-D have, and how does that help with PCB layout planning?
The TST-112-03-G-D has a body length of 1.5 inches (38.1 mm), a body breadth of 0.365 inches, and a body depth of 0.365 inches. These dimensions define the keep-out zone on the PCB for the connector and its shroud, allowing layout engineers to allocate sufficient board clearance around all 4 sides of the 24-pin dual-row header during component placement.
When should a designer choose the TST-112-03-G-D over the TST-112-03-H-D variant at the same 24-pin count?
The TST-112-03-G-D uses 10 µin gold mating finish and gold PCB termination, while the TST-112-03-H-D uses 30 µin gold mating finish with matte tin termination. Designers choose the TST-112-03-G-D when gold termination is required for board-level reliability or when the assembly process benefits from a fully gold-finished connector, and when the mating cycle count is moderate enough that 10 µin gold is sufficient rather than the heavier 30 µin coating.
