Needs validationhigh risk
Nichicon 100uF 35V SMD capacitor for redesign-level substitution.
Best Alternatives to 03EC0673
03EC0673 is a radial 100uF 35V aluminum electrolytic capacitor. The candidates found are SMD functional alternatives, not drop-in replacements.
AI replacement insight
Electrical riskmedium
capacitance and voltage mostly align; ESR/ripple are missing
Package riskhigh
all kept options are SMD, while target is radial
Firmware risklow
passive capacitor; no firmware impact expected
Sourcing risklow
kept candidates are active and catalog matched
Can it be replaced directly?
No pin-compatible replacement is confirmed from the provided candidates.
Best replacement path
Use a radial 100uF 35V part with 6x7mm body and 2.5mm lead spacing if a direct fit is required.
Main risk
The main risk is radial-to-SMD package mismatch.
