What are the key features of TST-103-03-L-D?
- 6-position dual-row shrouded PCB header with 2.54 mm pitch and low-profile (L) 0.365 inch body depth for height-constrained assemblies
- 10 µin gold over nickel mating contact finish provides corrosion resistance and stable low contact resistance for signal interface headers
- Rectangular male contact pattern mates with standard 2.54 mm dual-row female sockets for broad cross-vendor compatibility
- Tin (Sn) over nickel termination tails ensure solderability in wave and selective solder PCB assembly processes
- Shrouded body provides polarized mating key that prevents 180-degree misalignment of 6-position cable or board-to-board assemblies
What is TST-103-03-L-D used for?
The TST-103-03-L-D is used in embedded microcontroller boards, sensor interface modules, and industrial I/O headers where a low-profile 6-position dual-row shrouded connector is required for signal bus or programming interface access. Its gold contact finish suits JTAG debug headers, SPI expansion connectors, and other interfaces on evaluation and production PCBs requiring reliable mating with minimal contact resistance. The compact 0.6 inch × 0.365 inch footprint supports integration on space-constrained boards as small as 25 mm × 25 mm.

Frequently Asked Questions
How does the low-profile (L) designation of the TST-103-03-L-D differ from the standard-depth TST-103-03-F-D?
The -L suffix indicates a reduced body depth of 0.365 inches compared to the 0.485 inch depth of the -F (full height) variant. This 30% reduction in body depth allows the TST-103-03-L-D to fit in enclosures with tighter vertical clearance above the PCB, such as slim 6-position signal headers on board-mounted radio modules or flat industrial sensor nodes.
What is the factory lead time for the TST-103-03-L-D and how does it affect procurement planning?
SAMTEC lists the TST-103-03-L-D with a factory lead time of approximately 2 weeks and 6 days. Engineers specifying this 6-position dual-row header for production designs should maintain a buffer stock of at least 3 to 4 weeks of consumption to avoid line stoppages, particularly for products with annual volumes exceeding 1000 units where distributor stock may vary.
Which mating female socket is recommended for use with the TST-103-03-L-D in board-to-board assemblies?
SAMTEC's SSW or SSQ series dual-row female sockets at 2.54 mm pitch with 6 positions (3 contacts per row) are the recommended mating partners for the TST-103-03-L-D. The gold-plated male pins engage opposing gold-over-nickel female contacts to achieve a contact resistance below 30 milliohms per pin, ensuring signal integrity for I2C, SPI, or UART logic levels at 3.3 V or 5 V.
For a compact sensor module PCB, how much board area does the TST-103-03-L-D occupy?
The TST-103-03-L-D body measures 0.6 inches (15.2 mm) long by 0.365 inches (9.3 mm) wide, occupying approximately 141 mm² of PCB surface including a standard 0.5 mm keepout border. This small footprint allows placement of the 6-position dual-row shrouded header on sensor modules or breakout PCBs with total board areas under 30 mm × 30 mm without conflicting with nearby component keepout zones.
