What are the key features of TST-103-04-S-D?
- 6-position dual-row through-hole shrouded header at 2.54mm (0.100") pitch prevents mis-insertion and secures cable-to-board connections with positive polarization
- Gold-plated contacts rated up to 3A per pin enable reliable power and signal distribution in a single compact connector
- Shrouded housing (S option) provides robust keying, protecting adjacent circuitry from miswired cables during field servicing
- Through-hole mounting with compliant tails ensures high pull-out force retention, ideal for connectors subject to repeated mating cycles
What is TST-103-04-S-D used for?
TST-103-04-S-D is well suited for UART, SPI, and low-power GPIO ribbon-cable interfaces on microcontroller boards, where the shroud prevents reverse insertion of 6-pin IDC cables during prototyping and production. The 3A-per-pin current rating supports mixed signal-and-power harnesses in industrial control panels, robotics platforms, and test equipment that require a rugged 6-pin board header. Its 0.100" pitch is fully compatible with standard 2.54mm IDC connectors and development-board ecosystems.

Frequently Asked Questions
What pin count, pitch, and current rating characterize TST-103-04-S-D?
TST-103-04-S-D is a 6-position (3×2) dual-row header with a 2.54mm (0.100") pitch and gold-plated contacts rated at up to 3A per pin. The shrouded housing prevents mis-mating, and the through-hole tails provide mechanical retention forces exceeding 20N pull-out per the SAMTEC TST series specification.
How does the shrouded design of TST-103-04-S-D reduce field-wiring errors in cable harnesses?
The polarizing shroud on TST-103-04-S-D physically blocks reverse or offset insertion of mating 6-pin IDC connectors, reducing wiring errors to near zero in field-service scenarios. This is particularly valuable in industrial and robotics designs where technicians connect 2.54mm ribbon cables under time pressure, as the keyed shroud adds only 1.5mm to the connector height while providing unmistakable tactile alignment feedback.
Which communication protocols and signal types can TST-103-04-S-D carry given its electrical rating?
With 6 pins at 3A each and 2.54mm pitch, TST-103-04-S-D can carry UART, SPI, I2C, JTAG debug signals, and low-current power rails simultaneously in a single 6-pin harness. The gold plating maintains contact resistance below 20mΩ across the rated 30-cycle mating life, making it reliable for serial debug headers operating at 3.3V or 5V logic levels.
When should a designer choose TST-103-04-S-D over an unshrouded dual-row header for a prototype board?
TST-103-04-S-D is preferable over an unshrouded 6-pin header whenever the connector will be accessed by end users or field technicians, because the shroud eliminates reversed-cable damage risk. For bench prototypes that are only cabled by the design engineer, an unshrouded pin-header saves about 2mm of board height; however, in any production or field-deployed design with 6 signal pins at up to 3A, the shrouded TST-103-04-S-D is the safer choice.
