AISHI
A radial 47uF 50V candidate with matching basics but polymer and size differences.
03EC0571 is a radial 47uF 50V aluminum electrolytic capacitor. Current candidates need FAE review before substitution.
ESR, ripple and leakage need checking.
Most candidates are SMD, not radial.
Passive part; no firmware interface.
Some entries lack product URLs or ES support.
Direct replacement for 03EC0571 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Check SPZ1HM470E08O00RAXXX first if radial pitch and ESR are acceptable.
Package and capacitor technology differ across the candidates.
