DuPont and “DuPont” connectors, and how to crimp them properly
“DuPont connector” is a vernacular term which refers to a number of different types of 0.1″ pitch connector. They feature black plastic housings which retain contacts with fingers built into the housing body. All are very similar in appearance but vary significantly in quality and price.
There are various other names often attached to these, such as “TYU Connector” or “JWT Connector” (drop a comment if you know of another). These are acronyms for some of the many Chinese manufacturers, sometimes physically moulded into the product.
In some cases “DuPont connector” may refer to unrelated connector types which vaguely resemble the original design, however are significantly different in detail. Chinese reproductions of Molex SL / AMPMODU MTE and Molex CGrid III are some examples. On this page I’ll be sticking to the original series, and close look-a-likes.
Mini-PV was the first 0.1″ (2.54mm pitch) design of this type likely introduced in the 1950s by Berg Connectors which appears to have spent much of its life as a division of E. I. du Pont de Nemours and Company. Its contact measures 1.25mm square and features an elaborate bi-metallic design with a brass contact body and a beryllium alloy spring. As the heading suggests it has changed hands a few times since then.
