For example, a designer starts the design with an SRU1048, a 10mm footprint with a 4.8mm tall component. If a subsequent design change is required to lower the component’s height, the designer can switch to the SRU1028 with the same footprint and 2.8mm height without re-spinning the board. For other upgrade requirements, such as a higher current rating, SRU1063 is a 6.3mm tall component can be selected. Again, the footprint stays unchanged.
