What are the key features of TST-103-02-H-D?
- 6-position dual-row shrouded PCB header at 0.100" (2.54 mm) pitch for polarized, keyed board-to-wire connectivity
- 30 micro-inch gold over nickel contact finish on all 6 male square-pin contacts ensures low contact resistance and reliable mating
- Protective shroud body (0.365 inch x 0.600 inch) prevents mis-insertion and shields contacts from damage during assembly
What is TST-103-02-H-D used for?
The TST-103-02-H-D is used in board-to-wire harness connections for industrial control panels, embedded systems, and power distribution boards where 6-pin polarized connectivity is needed at 2.54 mm pitch. Its shrouded housing makes it a popular choice for ribbon cable headers in test and measurement equipment, programming interfaces, and consumer electronics requiring keyed, protected 0.100-inch pitch connectors. The gold-plated contacts ensure reliable signal integrity across repeated mating cycles in lab and field-service environments.

Frequently Asked Questions
What is the contact finish specification of the TST-103-02-H-D and why does it matter for connector reliability?
The TST-103-02-H-D features 30 micro-inch gold plating over nickel on all 6 male square-pin contacts. Gold plating at 30 micro-inches (0.76 micrometers) provides superior corrosion resistance compared to standard 15 micro-inch gold or tin finishes, maintaining low contact resistance across hundreds of mating cycles. This makes it suitable for reliability-sensitive applications in industrial control and test equipment.
How does the shroud on the TST-103-02-H-D protect against mis-insertion in multi-connector PCB assemblies?
The 0.100-inch pitch shrouded housing (0.365 inch x 0.600 inch body) physically keys and polarizes the connector, preventing a mating cable plug from being inserted in the wrong orientation or in an incorrect position among adjacent 6-pin headers. This eliminates reverse-polarity connection risk on all 6 circuits, which is especially important in power and signal mixed connectors on industrial PCBs.
Which cable assembly types mate with the TST-103-02-H-D for board-to-wire applications?
The TST-103-02-H-D mates with SAMTEC TST-series or equivalent 6-position dual-row 0.100-inch (2.54 mm) pitch female crimp socket housings, including IDC ribbon cable connectors and individual crimp-contact wire assemblies. The 2.54 mm pitch accepts AWG 26 to AWG 24 wire sizes typical of standard board-to-wire harnesses used in industrial automation, embedded systems, and low-voltage power distribution.
For a 6-circuit programming header on a microcontroller board, how does TST-103-02-H-D compare to an unshrouded header?
Unlike an unshrouded 6-pin header where any 6-pin plug can be inserted in either orientation or offset by 2 pins, the TST-103-02-H-D shroud enforces correct 6-circuit alignment and orientation at 2.54 mm pitch. In programming header scenarios with 6 pins (JTAG or ISP), this prevents reversed connections that could damage the microcontroller. The 30 micro-inch gold contacts also maintain reliable signal continuity across many repeated programming cable insertions.
