Frequently Asked Questions
What contact finish does HTSW-108-26-G-T use and why does it matter for mating reliability?
The HTSW-108-26-G-T uses gold (Au) plating over a nickel (Ni) barrier on its 24 male contacts. Gold provides excellent corrosion resistance and low contact resistance across hundreds of mating cycles, while the nickel barrier prevents gold diffusion into the base metal. This finish is ideal for signal connectors in industrial and instrumentation systems where contact reliability must be maintained over the product's operating life.
What are the physical dimensions of the HTSW-108-26-G-T header for PCB footprint planning?
The HTSW-108-26-G-T body measures 0.8 inch in length, 0.298 inch in breadth, and 0.1 inch in depth, housing 24 positions at 2.54 mm pitch in a single row. These dimensions allow designers to plan the PCB keepout and via pattern accurately, and the 0.1 inch row depth is consistent with standard through-hole header footprints used in industrial and development board designs.
How does HTSW-108-26-G-T compare to surface mount alternatives for prototype and low-volume production?
The through-hole vertical mounting of HTSW-108-26-G-T provides stronger mechanical retention than surface mount headers, making it preferable in connectors that will be mated and de-mated frequently or subjected to mechanical stress from cable pull. For 24-position interfaces at 2.54 mm pitch in development boards, test fixtures, or low-volume industrial products, through-hole mounting also simplifies manual soldering compared to small-pitch SMT alternatives.
What is the expected lifecycle availability for HTSW-108-26-G-T in long-running product designs?
The HTSW-108-26-G-T has a YTEOL (years to end of life) of 9.1 years, providing confidence in continued supply for designs intended for extended production or service periods. For industrial controllers and embedded systems expected to remain in production for 5 or more years, this YTEOL offers sufficient headroom, though procurement teams should monitor distributor stock and plan last-time-buy orders as the product approaches its end-of-life horizon.
