Is there a pin-compatible replacement for 100PX47MEFC8X11.5?

No pin-to-pin replacement is confirmed. While some radial parts are functionally similar, critical dimensions like lead spacing and case size must be verified against your board layout before ordering.

What risks should I check before replacing 100PX47MEFC8X11.5?

The main risk is mechanical fit. Check the case diameter, height, and lead spacing of any alternative to ensure it fits your PCB without physical or electrical interference.

AI replacement insight

Package riskmedium

Alternatives have different dimensions (height/diameter) that must be checked.

Electrical risklow

Candidates with matching key electricals (47µF, 100V) are available.

Can it be replaced directly?

No verified direct drop-in replacement has been identified. The best candidates require verification of physical fit, particularly case dimensions and lead spacing.

Best replacement path

The closest match is KM476M100F12RR0VH2FP0, which has the same diameter but is slightly taller. Other options may require PCB layout changes.

Main risk

The primary risk is mechanical incompatibility. Alternatives have different physical dimensions which may not fit the original PCB layout.

Recommended alternatives

Strong functional alternative with identical electricals and diameter, but slightly taller. Requires physical fit verification.
