- 6-position dual-row shrouded header with 2.54 mm pitch, providing polarized keyed mating to prevent connector misalignment
- Gold flash (3 µin) over Nickel mating contact finish delivers low-resistance, corrosion-resistant interconnects
- Rectangular square-pin contact style compatible with standard 0.100 inch pitch female sockets across multiple vendors
- Compact body (0.6 inch length × 0.485 inch depth) suits space-constrained PCB layouts
- Through-hole termination with tin-over-nickel finish ensures robust solder joint integrity in wave soldering
What is TST-103-03-F-D used for?
The TST-103-03-F-D shrouded PCB header is used in embedded controller boards, sensor modules, and industrial I/O panels where polarized dual-row connectivity with 6 positions prevents miswiring of signal and power lines. Its gold-flashed contacts make it appropriate for data acquisition systems and communication interfaces requiring repeated mate/unmate cycles. The compact 0.6 inch body fits standard 2.54 mm grid layouts, enabling straightforward integration in both prototype and production PCB designs.

Frequently Asked Questions
How does the shrouded design of the TST-103-03-F-D prevent connector mismating?
The TST-103-03-F-D's plastic shroud surrounds all 6 pins in the dual-row arrangement and provides a keying notch that physically prevents 180-degree reversal when mating with a corresponding female socket. The 0.6 inch body length ensures the mating connector seats fully before any electrical contact is made, reducing field wiring errors in industrial and embedded applications.
What contact finish does the TST-103-03-F-D use and how many mating cycles does it support?
The TST-103-03-F-D uses a gold flash (3 µin) over nickel contact finish on the mating interface and tin over nickel on the through-hole termination tails. Gold flash finishes typically support 25 to 50 mating cycles, making this connector suitable for board-level connectors that are mated infrequently, such as 2.54 mm pitch programming headers.
Which PCB soldering methods are compatible with the TST-103-03-F-D?
The TST-103-03-F-D uses through-hole square pins with a tin-over-nickel termination finish, making it compatible with wave soldering at temperatures up to 260°C and selective soldering processes. The 0.485 inch body depth requires adequate keepout on the solder side of the PCB to ensure the shroud clears wave solder nozzles during mass production assembly.
What dual-row female socket from SAMTEC mates with the TST-103-03-F-D?
SAMTEC's SSW or SSQ series dual-row female sockets with 2.54 mm pitch and 6 positions (3 per row) are designed to mate with the TST-103-03-F-D header. The square-pin (SQ PIN-SKT) contact style ensures a 30 to 50 gram per-pin normal contact force for reliable signal continuity in the mated pair.
