TSW-125-09-F-S-RA

Headers, Male Pins Overview

Samtec TSW-125-09-F-S-RA is a single-row, right-angle PCB header strip featuring a 2.54 mm (0.1 in) pitch and 25 positions. Constructed with phosphor bronze contacts plated with gold over nickel for the mating interface and tin over nickel for termination, it utilizes a black polybutylene terephthalate insulator rated UL 94 V-0. Designed for through-hole mounting, this male pin header supports board-to-board and cable applications within an operating temperature range of -55°C to +125°C.

Headers, Male Pins Feature Summary

• Right-angle configuration facilitates compact vertical interconnections on printed circuit boards.
• Gold-plated phosphor bronze contacts ensure reliable signal transmission and corrosion resistance.
• Standard .100 inch pitch allows compatibility with widely available mating socket strips.

Headers, Male Pins Applications

• Board-to-board interconnections
• Cable-to-board connections
• General electronic equipment prototyping

Headers, Male Pins Procurement Notes

Verify that the specific suffix 'F' confirms tin-plated solder tails rather than gold, as plating variations exist within the series. Confirm right-angle orientation matches the design layout requirements. Ensure the 25-position count aligns with the target circuit density. Cross-reference the UL 94 V-0 flammability rating against project safety standards. Validate the phosphor bronze contact material suitability for the intended current load.

Headers, Male Pins Selection Notes

Select this component when a low-profile, right-angle connection is required for standard 2.54 mm spacing. The tin-plated termination option offers cost efficiency compared to fully gold-plated variants while maintaining adequate solderability. Consider the single-row format for simpler routing needs where double-row density is unnecessary. Verify that the straight or right-angle form factor fits the mechanical constraints of the assembly enclosure.

Headers, Male Pins Part Context

The TSW series represents Samtec's classic line of PCB header strips, known for standardized dimensions and broad availability. This specific model belongs to the single-row subset, offering a straightforward solution for basic connectivity tasks. It complements other Samtec products like HTSW and ESQ by providing a reliable, industry-standard interface option for mass production and general engineering applications.

Headers, Male Pins Replacement Considerations

Compatible substitutes include Samtec TSW-125-09-G-S-RA for gold-plated termination or TSW-125-09-L-S-RA for lead-free wave soldering compatibility. Generic equivalents from other manufacturers must match the 2.54 mm pitch, 25-position count, and right-angle geometry precisely to ensure mechanical fit and electrical continuity.
