Frequently Asked Questions
How does the 5.08mm pitch of the TSW-212-17-G-Q compare to 2.54mm pitch headers for signal routing density?
The TSW-212-17-G-Q uses a 5.08mm (0.2 inch) pitch — double that of standard 2.54mm headers — which allocates more PCB spacing between contacts for higher current-carrying capacity per pin and easier hand-soldering in prototyping. The 24-way dual-row layout still provides sufficient conductor count for most embedded control and instrumentation signal buses.
What contact plating does the TSW-212-17-G-Q use and how does it affect connector longevity?
The TSW-212-17-G-Q uses gold-over-nickel plating on both the mating face and the PCB termination, providing corrosion resistance and low, stable contact resistance over the rated insertion cycle life. Gold plating is particularly beneficial in test and measurement fixtures where connectors are mated and unmated hundreds of times, maintaining signal integrity across all 24 positions.
For which development or test environments is the TSW-212-17-G-Q vertical header best suited?
The TSW-212-17-G-Q is best suited for development boards, break-out modules, and bench-level test fixtures where a 24-position dual-row header at 5.08mm pitch provides accessible, high-reliability connections for logic analyzers, power rails, and control signal buses. Its through-hole vertical design offers mechanical strength needed when mating and unmating development cables repeatedly during debugging sessions.
Does the TSW-212-17-G-Q body length affect its compatibility with standard PCB layouts for 24-way headers?
The TSW-212-17-G-Q body measures 2.3 inches (approximately 58.4mm) long and 0.3 inches wide, which corresponds to a standard dual-row 12-position-per-row 5.08mm pitch footprint. Engineers can use standard EDA footprint libraries for 24-way dual-row 5.08mm headers, and the vertical orientation keeps the mating direction perpendicular to the board, simplifying cable routing above the PCB.
