Is there a pin-compatible replacement for OVZ121M1ATR-0606?

OVK121M1ATR-0606 has identical package dimensions (6.3mm x 5.9mm) and is very likely pin-compatible. However, it is always best practice to verify the land pattern from the datasheet before substitution.

What risks should I check before replacing OVZ121M1ATR-0606?

Before replacing, verify that the alternative's ESR and ripple current ratings are acceptable for your application. Also, confirm the physical dimensions, especially height and land pattern, are compatible with your board layout.

OVZ121M1ATR-0606 Alternatives, Datasheet & Cross Reference | lelon

The Lelon OVZ121M1ATR-0606 is a 120µF 10V aluminum polymer capacitor in a 6.3x5.9mm SMD package. Several strong alternatives are available, including options from Lelon and Panasonic, but require review of key electrical parameters like ESR and ripple current.

AI replacement insight

Electrical risklow

Candidates have similar or better ratings, but minor differences in ESR/ripple exist.

Package risklow

Candidates have nearly identical package dimensions, but land pattern verification is always recommended.

Sourcing risklow

Alternatives are from major manufacturers, but stock levels should be checked.

Can it be replaced directly?

No drop-in replacement has been fully verified. OVK121M1ATR-0606 is the most likely candidate for a direct replacement, but its slightly different ESR and ripple current ratings should be reviewed.

Best replacement path

For a minimal change, consider OVK121M1ATR-0606 from the same manufacturer. For a performance upgrade, 20SVPF120M from Panasonic offers higher voltage and ripple current ratings.

Main risk

The primary risks are minor electrical parameter differences (ESR, ripple current) and ensuring the physical land pattern of any alternative matches your PCB layout.

Recommended alternatives

Strong alternative from the same manufacturer with identical core specs and package size.
