Blower motor run capacitor replacement
Most likely the Nichicon EEC you found on Digikey is configured as a 'DC-link' - the terminals closest to each other are internally paralled. This simplifies wiring (saves you a junction) if you are using it as a filter (between a source and a load).
Note that the EEC capacitor does not appear to be a UL-recognized component; the original All-Earth is (the backwards UR logo on the bottom-left of the silkscreened area). I recommend you ensure your replacement parts are UL-recognized for safety reasons.
