A strong alternative with matching key electricals and package size; verify footprint.
Finding a substitute for the ROQANG CS1H331M-CRG10, a 330µF 50V SMD aluminum capacitor, involves matching key electricals and the 10x10.2mm package. Several strong candidates exist, but careful verification of the PCB footprint is essential.
Several candidates have matching SMD package dimensions but require footprint verification. Others are THT and not form-fit.
Multiple candidates match or safely exceed the target's capacitance and voltage ratings.
Alternatives are available from multiple manufacturers (KNSCHA, ROQANG, AISHI).
Direct replacement for CS1H331M-CRG10 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
RVT330UF50V167RV0080 and RVT1H331M1010 are the strongest candidates, matching key specs and package size, but require footprint verification before use.
The primary risk is mechanical incompatibility. Many functional alternatives use a different (through-hole) package, while even size-matched SMD parts require footprint verification.
