Is there a pin-compatible replacement for MPP104J2J10AJ22630?

Several candidates like MPP104J2W10AJ22620 and KP104J2G1016 share the same package and 10mm lead pitch, but they are not electrically equivalent due to lower voltage ratings.

What risks should I check before replacing MPP104J2J10AJ22630?

Key risks include: 1. Voltage: Ensure the replacement's voltage rating is sufficient for your circuit. 2. Application: Do not substitute a general-purpose capacitor with a safety-rated (X2) part without analysis. 3. Temperature: Check if the operating temperature range is sufficient.

AI replacement insight

Electrical riskhigh

Most candidates have significantly lower voltage ratings.

Package risklow

Several candidates match the radial 10mm pitch package.

Sourcing riskmedium

Finding an exact 630V, 100nF, 10mm pitch film cap may require searching across more vendors.

Can it be replaced directly?

No, there are no direct pin-compatible replacements in this list that match all key electrical parameters. All options present a downgrade or functional difference.

Best replacement path

No direct drop-in replacement found. All candidates require engineering review due to lower voltage ratings or different application types.

Main risk

The primary risk is using a capacitor with a lower voltage rating (e.g., 400V or 450V) in a 630V application, which can lead to component failure.

Recommended alternatives

Same form and capacitance but has a lower voltage rating, requiring engineering review.
