ROQANG
Functionally similar with a higher voltage rating, but is physically much larger and requires board space verification.
Finding a substitute for the ROQANG GR1C221M0607, a 220µF 16V through-hole capacitor, requires careful review of package size and mounting type. While several parts offer similar electrical specs, physical compatibility is the main challenge.
All candidates are either physically larger or use a different mounting technology (SMD vs. THT).
All candidates match or exceed the target's key electrical ratings (capacitance, voltage).
No, there are no direct drop-in replacements for GR1C221M0607 among the candidates reviewed. All options have significant physical differences in size or mounting type.
For existing boards, verify if the larger through-hole part KM1H221M1013 can fit. For new designs, any of the SMD candidates like VZH221M1VTR-0810L offer upgraded voltage and AEC-Q200 qualification.
Physical incompatibility. The primary risk is that no candidate will fit an existing PCB layout designed for the target part without modification.

There is no single 'best' alternative. For existing boards, KM1H221M1013 is a functional option if the larger size (10x13mm) is acceptable. For new designs, SMD parts like VZH221M1VTR-0810L are excellent functional alternatives with upgraded voltage and automotive qualification.
