I'm super confused about some of the PCBs when it comes to film box caps vs MLCCs. The guides almost never specify the capacitor types, so I'm assuming if there's a box icon on the PCB it means I should use a box film cap unless the guide says MLCC (some, like Hydra, do). Thing is, for example on the Stockade, it has a box for 47p on the PCB -- but my Mouser searching skills must be terrible, because I can't find a box cap in 47p that's 2.5mm wide and 5mm lead spacing, which is the size of the icon on the PCB. All of the 47p film box caps appear to be 4.5 mm wide. While I can probably jam it in there sideways, I ideally want everything to fit perfectly.
Anyone care to enlighten me on what I'm doing wrong? Should I be using MLCC for the "p" cap values? Is there some unknown rule I should be following about when to use MLCC vs film caps, if the guide doesn't say, and the PCBs all seem to use the "box cap" icon?
