What are the key features of TST-103-02-G-D?
- 6-position dual-row shrouded header on 0.100 inch (2.54 mm) pitch provides secure polarized mating to prevent connector mis-insertion
- Gold (10 µin) over nickel contact finish on both mating and termination surfaces ensures low contact resistance and long mating cycle life
- Square-pin male contact style ensures positive wiping action against female socket contacts for reliable electrical connection
- Compact body footprint of 0.600 inch length by 0.365 inch width fits standard dual-row 0.1-inch grid PCB layouts
- Shrouded housing protects pins during handling and guides mating connectors for repeatable insertion in field-serviceable assemblies
What is TST-103-02-G-D used for?
The TST-103-02-G-D is used in PCB-to-cable and board-to-board interconnect applications where a compact, polarized 6-pin dual-row header with standard 0.100 inch pitch is required. It is commonly found in development boards, embedded controller modules, industrial I/O interface panels, and robotics wiring harnesses where reliable repeated mating and gold-plated contacts are essential. The shrouded design makes it well suited for field-replaceable cable assemblies and test-fixture interfaces in automated production environments.

Frequently Asked Questions
How does the 0.100 inch pitch on TST-103-02-G-D compare to fine-pitch alternatives for dense board layouts?
The 0.100 inch (2.54 mm) pitch of TST-103-02-G-D is the industry-standard grid spacing for through-hole and surface-mount headers, making it compatible with a vast ecosystem of mating sockets and ribbon cable assemblies. Fine-pitch alternatives at 0.050 inch (1.27 mm) or 0.079 inch (2.00 mm) pack more contacts into a smaller area but require tighter PCB tolerances and are harder to hand-wire, so 0.100 inch remains preferred for prototype boards and serviceable field connectors.
What contact plating does TST-103-02-G-D use, and how many mating cycles does gold plating typically support?
TST-103-02-G-D uses 10 microinches of gold over a nickel barrier on both mating and termination surfaces. Gold plating at 10 µin thickness is rated for approximately 100 to 500 mating cycles depending on the mating force and contact geometry, providing stable contact resistance below 20 mΩ throughout its service life and resisting corrosion in industrial environments with humidity up to 95% RH.
For a 6-pin cable harness on a robotics controller, why is the shrouded housing of TST-103-02-G-D important?
The shrouded housing physically guides the mating receptacle into the correct orientation, preventing the 6-pin connector from being inserted rotated 180 degrees, which could damage circuitry. In a robotics application where cables are connected and disconnected frequently by technicians under time pressure, the polarized shroud reduces assembly errors to near zero versus unshrouded headers, lowering field failure rates.
How does the body size of TST-103-02-G-D constrain PCB real estate in an embedded controller design?
The TST-103-02-G-D body measures 0.600 inch long by 0.365 inch wide (approximately 15.2 mm x 9.3 mm), occupying about 141 mm² of PCB area for a 6-position dual-row header on 0.100 inch pitch. Designers must reserve a keepout zone around the shroud of at least 1 mm on each side for mating connector clearance, making the total footprint approximately 17 mm x 11 mm in tight layouts.
