Key Features
- 20-position vertical THT receptacle on 5.08 mm pitch with 1.9-inch body for high-density board-to-board signal distribution
- Gold-over-nickel contact finish on both mating and termination surfaces ensuring low contact resistance and corrosion protection across repeated mating cycles
- RoHS-compliant (Pb-free) construction meeting environmental regulations for consumer, industrial, and medical PCB assemblies
Applications
The TSW-210-20-G-Q is used in prototyping boards, development kits, and production PCBs where a 20-way vertical receptacle on 5.08 mm pitch provides reliable wire-to-board or board-to-board connections for power and signal distribution. Its gold contact finish makes it suitable for high-cycle test and measurement fixtures, daughter card interfaces, and relay control boards that demand low contact resistance over thousands of insertions. The RoHS-compliant through-hole design supports wave soldering and selective soldering processes in industrial automation and medical device assembly.

Frequently Asked Questions
What pitch and position count does the TSW-210-20-G-Q offer, and how does that affect wiring density?
The TSW-210-20-G-Q provides 20 positions on a 5.08 mm (0.200-inch) pitch, resulting in a 1.9-inch total body length. This coarser pitch compared to 2.54 mm alternatives allows easy hand-wiring with standard 22 AWG to 26 AWG hook-up wire in prototype rigs and field-serviceable control panels, while still delivering 20 signals in a single in-line receptacle.
What contact plating does the TSW-210-20-G-Q use and why does gold plating matter for connector longevity?
Both the mating and termination contacts are finished with gold over a nickel barrier layer. Gold prevents the oxide layer formation that increases contact resistance over time, ensuring the connector maintains resistance below 20 mΩ per contact across 500 or more mating cycles — a typical requirement for development board sockets, test fixtures, and removable daughter cards used in industrial automation and laboratory equipment.
Is the TSW-210-20-G-Q suitable for high-cycle test fixture applications?
Yes. The gold-over-nickel contact finish and robust through-hole termination make the TSW-210-20-G-Q a strong candidate for test fixture receptacles that undergo dozens of insertions per day. Its 20-position layout accommodates common microcontroller or FPGA I/O groupings of 8, 16, or 20 signals, and the 5.08 mm pitch accommodates standard 100-mil SIL probe pins used in in-circuit test (ICT) adapters.
Can the TSW-210-20-G-Q replace a standard 0.100-inch pitch header in a redesign targeting easier hand assembly?
The TSW-210-20-G-Q uses a 5.08 mm (0.200-inch) pitch, which is twice the spacing of standard 2.54 mm (0.100-inch) headers. While it requires more board space — approximately 1.9 inches for 20 positions — this wider pitch significantly reduces hand-soldering bridging risk and simplifies wire termination on control panels or field-wired junction boards where technician-friendly connectors are prioritized over miniaturization.
