Frequently Asked Questions
What contact finish does the 61031021121 use and how does it affect reliability?
The Würth Elektronik 61031021121 uses gold (Au) plating over a nickel (Ni) barrier on its mating contacts. Gold plating provides a noble metal surface that resists oxidation and corrosion, ensuring stable contact resistance typically below 20 mΩ even after hundreds of mating cycles. The nickel barrier prevents gold diffusion into the copper base, maintaining the long-term integrity of the 10-position dual-row 2.54 mm pitch connector in demanding environments.
How many pieces come per reel for the 61031021121, and what assembly equipment is it compatible with?
The 61031021121 is supplied in tape-and-reel packaging with 300 pieces per reel, which is formatted to work with standard pick-and-place automated assembly machines. This reel quantity is well-suited for medium-volume production runs where manual placement of the 10-position 2.54 mm pitch dual-row SMT header would be too slow or inconsistent, and the tape format ensures accurate feeder alignment during high-speed SMT assembly.
Does the 61031021121 include a cap, and what purpose does it serve during PCB assembly?
Yes, the 61031021121 includes a protective cap on the pin header. The cap shields the gold-plated male contacts from solder flux contamination, mechanical damage, and ESD during the PCB reflow soldering process. Removing the cap after soldering reveals 10 clean, undamaged 2.54 mm pitch contacts ready for mating with a compatible female header or socket connector, reducing rework costs in automated assembly lines.
