AISHI
Physically compatible with identical key electricals, but has a significantly shorter operational lifetime.
The AISHI EHS2GM470K20OT is a 47µF 400V radial aluminum electrolytic capacitor with a 5000-hour lifetime. When seeking alternatives, it's crucial to match capacitance, voltage, and physical dimensions (13x20mm), while also verifying lifetime for your application.
Many alternatives have different physical dimensions, requiring layout changes.
Lifetime is a common downgrade risk; ripple current and ESR must also be verified.
47uF/400V is a common value, but high-endurance versions are less common.
No direct, fully equivalent replacement was found. AISHI EWH2GM470K20OT is physically identical but has a shorter lifetime, while EHF2GM470L20OT is electrically superior but physically larger.
Prioritize AISHI's EHF series if board space allows for a wider 16mm diameter, as it matches the endurance. If size is fixed, accept a lifetime downgrade with the EWH series.
The primary risk is finding a part that matches both the 13x20mm package and the 5000-hour high-endurance rating.

The AISHI EHF2GM470L20OT offers identical electrical specs and a comparable lifetime, but is physically wider (16mm vs 13mm). For a size-compatible option, EWH2GM470K20OT fits but has a shorter lifetime (2000h vs 5000h). Always verify board space and lifetime requirements.
