What are the key features of TST-109-01-T-D?
- 18-position dual-row shrouded header at 0.100 inch pitch provides 18 protected contacts in a compact 1.2 inch x 0.365 inch body, preventing contact damage during cable assembly and field service
- 200 microinch tin (Sn) over nickel (Ni) mating finish on square pin contacts ensures low and stable contact resistance through hundreds of mating cycles in cost-sensitive board-to-board applications
- Integral polarized shroud aligns and guides mating socket connectors across all 18 positions, eliminating mis-insertion and reverse-polarity errors in 0.100 inch pitch cable-to-board interfaces
What is TST-109-01-T-D used for?
The TST-109-01-T-D is suited for through-hole board-to-board and ribbon cable-to-board interconnect in industrial automation equipment, embedded control systems, and consumer electronics where a compact 18-position shrouded header at 0.100 inch pitch is required. Its protective shroud and polarization features make it well adapted to panel-mount and DIN-rail applications where cables are connected and disconnected regularly by field technicians. The 200 microinch tin mating finish provides durable electrical contact in cost-optimized production designs requiring reliable performance over many mating cycles.

Frequently Asked Questions
How does the 200 microinch tin mating finish on the TST-109-01-T-D compare to a gold mating finish for typical cable-to-board applications?
A 200 microinch tin (Sn) over nickel mating finish on the TST-109-01-T-D provides robust contact performance for applications with fewer than 100 to 200 mating cycles, which covers most cable-to-board and board-to-board interconnects in industrial and consumer equipment. Gold finishes are preferred for thousands of mating cycles, but the 200 microinch tin offers a more cost-effective choice when the 18-position header is mated infrequently, such as during initial system assembly or occasional field maintenance.
What physical space does the TST-109-01-T-D occupy on a PCB, and how does its shroud affect component clearance planning?
The TST-109-01-T-D has a body length of 1.2 inch, depth of 0.365 inch, and breadth of 0.365 inch, requiring a rectangular keep-out zone of approximately 30.5 mm x 9.3 mm on the PCB for the connector body alone. The shroud adds height above the board, so designers must ensure at least 8 mm to 10 mm of vertical clearance above the mated connector to allow the ribbon cable or mating socket to exit without straining the contacts in the 18-position 0.100 inch pitch header.
For which embedded systems applications is the TST-109-01-T-D a more practical choice than a 0.050 inch pitch 18-position header?
The TST-109-01-T-D at 0.100 inch pitch is preferred in embedded systems where standard IDC ribbon cables are used, since 0.100 inch pitch is the native pitch for 28 AWG and 26 AWG flat ribbon cables and their corresponding IDC sockets. This eliminates the need for adapter cables or custom wiring harnesses. In PLCs, motion controllers, and HMI panels where 18-signal I/O wiring is common, the 0.100 inch pitch shrouded header ensures broad compatibility with off-the-shelf cable assemblies.
