Beginning with its first fountain pens in 1929, Pelikan has featured interchangeable nib units. Initially, nib interchangeability was not intended for the customer; rather, it was to make dealers’ lives easier by allowing them to offer a variety of nib styles without having to stock a complete pen for each style. When a customer chose a pen, the dealer would install the desired nib unit into it for the customer. We follow that same practise today, however, many users want to interchange their own nib. This page provides a reference to nib interchangeability in Souverän and Tradition models (M-series fountain pens).

Some — but not all — models’ nibs can fit into other models. This chart lays out which nibs fit which pens. Some models’ nibs will fit into the Pelikan 140 and 400-series pens from the 1950s onward as well; these nibs are so noted in the chart.
