AI replacement insight
Electrical risklow
Select a capacitor with 47µF capacitance, ±20% tolerance, and a voltage rating of 80V or higher.
Package riskmedium
Must match radial package with 8mm diameter and ~3.5mm lead spacing. Height is less critical but should be checked.
Sourcing risklow
This is a common capacitor value with many alternative manufacturers.
Can it be replaced directly?
Yes, direct pin-compatible replacements for the LKMC1101K470MF are available. Options like the Rubycon 100PX47MEFC8X11.5 match the physical dimensions and provide an equal or better voltage rating.
Best replacement path
The best replacement path is selecting a pin-compatible radial capacitor with a voltage rating of 80V or higher, such as the Rubycon 100PX47MEFC8X11.5, which offers an identical footprint and an upgraded voltage rating.
Main risk
The main risk when substituting is physical incompatibility. Ensure the replacement capacitor's diameter and lead spacing match the original to fit the PCB layout. Also verify vertical clearance.
