Frequently Asked Questions
What pitch and contact finish does the TST-103-03-S-D use?
The TST-103-03-S-D uses a standard 0.100 inch (2.54 mm) pitch with gold (30 microinch) over nickel mating contacts, which provides excellent corrosion resistance and low contact resistance over thousands of mating cycles. The termination contacts use tin over nickel barrier finish, compatible with common lead-free solder processes and reflow temperatures up to 260°C.
How many positions does the TST-103-03-S-D provide and what board area does it occupy?
The TST-103-03-S-D has 6 positions in a dual-row shrouded configuration with a body length of 0.6 inch and body breadth and depth each of 0.365 inch. This compact footprint allows routing 6 discrete signals or mixed power and signal lines through a single 0.100 inch pitch connector, making it efficient for dense PCB designs in instruments, computing modules, and embedded control boards.
For which embedded or instrumentation applications is the TST-103-03-S-D most appropriate?
The TST-103-03-S-D is most appropriate for embedded SBC boards, test fixture interfaces, and industrial I/O modules where a polarized 6-position shrouded header at 0.100 inch pitch ensures correct cable orientation. Its 30 microinch gold contacts suit applications requiring reliable signal integrity across UART, SPI, I2C, or digital I/O interfaces, and the shroud protects the 6 male pins during repeated cable assembly in field-maintenance scenarios.
How does the TST-103-03-S-D shrouded design reduce assembly errors compared to an unshrouded header?
The shroud on the TST-103-03-S-D physically guides the mating connector into correct alignment, preventing the 6-pin male contact array from being inserted upside-down or offset by 1 position. This mechanical keying eliminates a common source of PCB damage in cable assembly and field service, particularly important in industrial control and embedded computing environments where mis-insertion at 0.100 inch pitch can short adjacent pins carrying power and signal lines simultaneously.
