Is there a pin-compatible replacement for GR1E221M0611?

Yes, the CapXon KF221M035F115A is a pin-compatible upgrade with identical physical dimensions and lead spacing. The DMBJ JBLH2221M035D090RLM is also pin-compatible with a smaller height.

What risks should I check before replacing GR1E221M0611?

Before replacing, check three main risks: 1) Physical Size: Ensure the candidate's diameter and height fit your PCB layout. 2) Impedance (ESR): A higher value can cause instability or overheating. 3) Voltage Rating: Never use a lower voltage rating; equal rating carries some risk.

AI replacement insight

Package riskmedium

Several alternatives are physically larger and require board layout verification.

Electrical riskmedium

Using a part with higher impedance or no voltage margin is a significant performance and reliability risk.

Sourcing risklow

Multiple manufacturers produce suitable low-impedance 220µF capacitors.

Can it be replaced directly?

Yes, several direct replacements exist. The CapXon KF221M035F115A is a strong candidate, offering upgraded voltage and impedance in the same package size.

Best replacement path

Upgrade to a part with a higher voltage rating (e.g., 35V) and lower impedance, such as the CapXon KF221M035F115A, which matches the physical size.

Main risk

The primary risks are selecting a replacement with a larger physical size that won't fit the PCB, or choosing a part with higher impedance (ESR) which can degrade circuit performance.

Recommended alternatives

A 220µF 35V capacitor with lower impedance and the same physical size, representing a strong upgrade path.
