Is there a pin-compatible replacement for OVK121M1ATR-0606?

Lelon's OVZ121M1ATR-0606 shares the same package and key electricals, but has a lower endurance rating (2000h vs 5000h). Panasonic's 20SVPF120M is also a likely fit but requires footprint verification.

What risks should I check before replacing OVK121M1ATR-0606?

Key risks include differences in endurance rating (lifetime), ESR, and ripple current handling. Also, confirm the substitute's physical dimensions and solder pad layout match your PCB design.

AI replacement insight

Electrical riskmedium

Endurance rating may be lower on some alternatives.

Package risklow

Candidates have identical or near-identical packages, but footprint verification is advised.

Can it be replaced directly?

No perfect drop-in replacement was found. The closest options require trade-offs: Lelon's OVZ121M1ATR-0606 has lower endurance, and Panasonic's 20SVPF120M requires footprint verification.

Best replacement path

Panasonic 20SVPF120M offers an upgrade in voltage with matching endurance. Lelon OVZ121M1ATR-0606 is a form-fit match but a downgrade in endurance.

Main risk

The primary risk is component lifetime, as some alternatives have significantly lower endurance ratings. Physical package fit is a secondary risk.

Recommended alternatives

Form-fit and electrical match from the same manufacturer, but with a significantly lower endurance rating.
