Key Features
- 9-position right-angle through-hole male header with 2.54 mm (0.100 inch) pitch for standard PCB footprint compatibility
- Gold flash over nickel mating contacts with tin-over-nickel termination for excellent conductivity and corrosion resistance
- Phosphor bronze contact material providing superior spring retention and long insertion-cycle durability
- Right-angle PTH (pin-through-hole) mounting allows horizontal cable exits parallel to the PCB surface, saving vertical clearance
Applications
The TSW-109-25-F-S-RA is widely used in prototyping boards, development kits, and embedded systems where a compact 9-pin right-angle header is needed to connect ribbon cables, jumper wires, or daughter cards. Its 2.54 mm pitch makes it compatible with standard breadboards and IDC ribbon connectors, making it ideal for test-and-measurement equipment, industrial control panels, and consumer electronics prototypes requiring reliable board-to-board or board-to-wire signal routing.

Frequently Asked Questions
What is the pitch and pin count of the TSW-109-25-F-S-RA, and how does that affect PCB layout?
The TSW-109-25-F-S-RA features a 2.54 mm (0.100 inch) pitch with 9 pins arranged in a single row. This standard pitch keeps the body length at approximately 0.9 inch and is directly compatible with universal 0.1-inch-grid PCB footprints, breadboards, and standard IDC ribbon-cable sockets, simplifying layout and sourcing.
How does the right-angle orientation of the TSW-109-25-F-S-RA benefit space-constrained enclosure designs?
The right-angle (RA) through-hole mounting routes mating cables horizontally along the PCB surface rather than vertically away from it. This orientation reduces the total height profile of the assembly by eliminating the need for vertical cable clearance above the board, making it well-suited for enclosures with height constraints of 16 mm or less above the PCB plane.
What contact finishes are used on the TSW-109-25-F-S-RA and why does that matter for mating cycles?
Mating contacts are finished with gold flash over nickel (50 micro-inches) and termination contacts use tin over nickel. Gold flash provides low contact resistance (typically below 20 mΩ) and protection against oxidation, supporting reliable electrical performance over hundreds of insertion cycles in prototyping and light-duty industrial applications.
Which applications are best served by the TSW-109-25-F-S-RA single-row right-angle header?
This 9-position 2.54 mm single-row right-angle header is ideal for development boards, sensor breakout modules, test-and-measurement instruments, and industrial I/O expansion cards that need to route up to 9 signal or power lines horizontally off the board edge. It handles mixed-signal and low-voltage logic levels up to the rated working voltage, accommodating 3.3 V and 5 V digital bus connections.
