AISHI
Strong functional match with identical electricals and lifetime, but in a smaller package.
Find alternatives for the AISHI EHF2GM470L20OT, a 47µF 400V long-life aluminum electrolytic capacitor. Key considerations for replacement include lifetime, ripple current, and physical dimensions (16mm x 20mm).
Most alternatives have different physical dimensions (diameter or length).
Many alternatives have significantly lower lifetime ratings, which is a critical electrical parameter.
No, a direct drop-in replacement is not confirmed. All reviewed candidates have physical or performance differences that require engineering review.
The AISHI EHS2GM470K20OT is the most promising path, matching key electricals and lifetime. The main task is to verify the smaller package fits the PCB layout.
The primary risk is a mismatch in component lifetime, as the target part is a long-life capacitor. A secondary risk is the physical package size.

| Feature / factor | EHF2GM470L20OT | EHS2GM470K20OT | ERH2WM470L25OT | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Capacitance | 47µF | 47µF | - | 47µF — Identical capacitance. | |
| Voltage | 400V | 400V | 450V | 400V / 450V — Identical voltage rating.; ERH2WM470L25OT: Higher voltage rating provides more margin. | |
| Package | Radial, 16mm x 20mm | Radial, 13mm x 20mm | Radial, 16mm x 25mm | Radial, 13mm x 20mm / Radial, 16mm x 25mm — Smaller diameter, may require layout check.; ERH2WM470L25OT: Longer body may not fit vertically. | |
| Lifetime | 5000-8000h @ 105°C | 5000h @ 105°C | 3000h @ 105°C | 5000h @ 105°C / 3000h @ 105°C — Matches lower end of target's range.; ERH2WM470L25OT: Significant downgrade in endurance. |
AISHI's EHS2GM470K20OT is a strong candidate, offering identical electrical specs and lifetime in a smaller package. However, verification of lead spacing and board layout is essential before use.
