What are the key features of TST-109-01-L-D?
- 18-position dual-row shrouded header at 2.54 mm pitch with polarized housing prevents mismating on crowded boards
- Gold (10 µin) over nickel mating contact finish ensures low contact resistance and corrosion resistance over thousands of cycles
- Square-pin contact style with tin-over-nickel PCB termination compatible with standard wave-solder and through-hole assembly
What is TST-109-01-L-D used for?
TST-109-01-L-D is widely used on development boards, evaluation kits, and test jigs where 18-pin dual-row headers at 2.54 mm pitch connect ribbon cables or jumper wires to target circuitry. The gold-plated mating contacts ensure low-loss signal paths for GPIO, SPI, and UART debug interfaces accessed frequently during firmware development. The shrouded polarized housing prevents incorrect cable orientation in field-test and production functional test applications.

Frequently Asked Questions
What pitch and contact finish does TST-109-01-L-D use for reliable signal connections?
TST-109-01-L-D uses 2.54 mm (0.100 inch) pitch with gold (10 µin) over nickel mating contacts, providing low contact resistance and robust corrosion protection across the 18-position dual-row header for repeated mating cycles in debug and test applications.
How does the shrouded housing of TST-109-01-L-D prevent cable mismating on populated development boards?
The shrouded and keyed housing on TST-109-01-L-D mechanically polarizes the 18-position 2.54 mm pitch header so ribbon cables and IDC connectors can only be inserted in the correct orientation, preventing reverse-connection damage to GPIO and SPI interfaces during firmware development.
What are the body dimensions of TST-109-01-L-D and how do they suit standard PCB layouts?
TST-109-01-L-D has a body length of 1.2 inches (approximately 30.5 mm) and body breadth of 0.365 inches, aligning with standard 2.54 mm grid PCB footprints used in development boards, evaluation kits, and 18-pin dual-row IDC cable assemblies.
Which assembly process is TST-109-01-L-D designed for and what termination finish does it use?
TST-109-01-L-D is designed for through-hole wave-solder or hand-solder assembly, with tin (Sn) over nickel (Ni) barrier PCB termination pins that wet reliably with standard Sn-Ag-Cu lead-free solder pastes in production SMT and mixed-assembly manufacturing lines.
