Murata Electronics
NFM21PC105B1C3D is a same-size Murata feedthrough cap but is electrically derated.
NFM21PC475B1A3D is a 4.7uF, 10V, 6A Murata 3-terminal EMI feedthrough capacitor. Reviewed alternates are derated and need validation.
Candidate is below 6A and 4.7uF.
Closest candidate uses 0805.
Passive part; no firmware impact.
Lifecycle data is limited.
Direct replacement for NFM21PC475B1A3D should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Use NFM21PC105B1C3D only as a derated option after FAE review.
Lower current and capacitance can change loss and EMI attenuation.
