Is there a pin-compatible replacement for 3A222J114CL011?

KNSCHA 2J222J114CL005 is pin-compatible (5mm pitch) but has a lower voltage rating (630V vs 1000V), making it a high-risk downgrade. It is not a direct replacement.

What risks should I check before replacing 3A222J114CL011?

Key risks include: 1) Voltage Rating: Ensure the replacement meets or exceeds 1000V. 2) Package: Verify the lead pitch matches the 5mm PCB layout. 3) Dielectric: Different materials can affect performance.

AI replacement insight

Electrical riskhigh

Using a part with a lower voltage rating (e.g., 630V) can lead to component failure.

Package riskhigh

Alternatives with different lead pitches (e.g., 15mm) require PCB redesign.

Can it be replaced directly?

There are no direct, pin-compatible replacements for 3A222J114CL011 with the same or better voltage rating in the provided candidates. All options have significant differences.

Best replacement path

No direct drop-in replacement was found. The closest options involve either a voltage downgrade or a different package requiring board modification.

Main risk

The primary risks are using a part with an insufficient voltage rating or a part that does not physically fit the PCB layout.

Recommended alternatives

Form-fit match with identical capacitance, but a lower voltage rating of 630V.
