Applications
The TSW-212-19-G-Q is used in test and measurement equipment, development boards, and prototyping systems where reliable 24-position vertical through-hole connections are needed on a 5.08 mm pitch grid. Its gold-plated contacts ensure low-resistance mating cycles suitable for board-to-board signal routing in laboratory instruments and industrial control panel wiring. The vertical THT mounting provides robust mechanical retention for applications subject to vibration or repeated mating cycles.

Frequently Asked Questions
What is the contact pitch of TSW-212-19-G-Q and which mating connectors are compatible with it?
The TSW-212-19-G-Q uses a 5.08 mm (0.2-inch) pitch, which is compatible with SAMTEC's TSW and SSW series socket connectors on the same pitch. This standard pitch is widely used in wirewrap tooling, development boards, and instrumentation backplane connections, enabling easy sourcing of compatible mating halves from multiple connector manufacturers.
How does gold-over-nickel contact finish on TSW-212-19-G-Q improve connector reliability over plated alternatives?
Gold-over-nickel plating provides superior corrosion resistance and stable contact resistance over thousands of mating cycles, typically maintaining contact resistance below 20 mΩ. The nickel barrier prevents gold diffusion into the copper base contact while the gold surface prevents oxidation, making the TSW-212-19-G-Q reliable in humid or mildly corrosive laboratory and industrial environments where tin-plated connectors would degrade faster.
For a 24-way prototype bus, how does TSW-212-19-G-Q's 5.08 mm pitch affect PCB layout versus tighter-pitch alternatives?
At 5.08 mm pitch, a 24-way single-row TSW-212-19-G-Q spans approximately 58 mm (23 × 5.08 mm) on the PCB, which is significantly larger than 2.54 mm pitch equivalents spanning 58 mm for 24 pins would. The wider 5.08 mm pitch simplifies through-hole drilling and soldering for prototyping applications but limits use in space-constrained production designs where 2.54 mm or 2 mm pitch connectors are standard.
