A potential pin-compatible replacement with identical key specs and package size.
Finding a substitute for the FOLLON EFVH050ADA220M0654 22uF 50V capacitor involves checking for compatible package dimensions, voltage, and lifetime ratings. Several strong alternatives exist, but careful verification is key.
Several candidates have slightly different heights or significantly larger footprints, requiring layout changes.
Most candidates match key electricals. One has a shorter lifetime, which must be evaluated for the application.
Direct replacement for EFVH050ADA220M0654 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
The strongest candidate is RVT1H220M0605, which matches all key parameters and package dimensions, making it a potential pin-for-pin replacement pending datasheet verification.
The primary risk when substituting is physical incompatibility. Several functional alternatives have different package sizes or heights that require careful mechanical and PCB layout verification.

| Feature / factor | EFVH050ADA220M0654 | RVT1H220M0605 | VZH220M1HTR-0606L | VES220M1HTR-0605 | Compatibility / risk |
|---|---|---|---|---|---|
| Package | SMD, 6.3mm x 5.4mm | SMD, 6.3mm x 5.4mm | 6.3mm x 5.7mm | 6.3mm x 5.3mm | SMD, 6.3mm x 5.4mm / 6.3mm x 5.7mm / 6.3mm x 5.3mm — Package dimensions match.; VZH220M1HTR-0606L: Slightly taller (0.3mm), requires vertical clearance check.; VES220M1HTR-0605: Slightly shorter (0.1mm), which is generally acceptable. |
| Capacitance | 22uF | 22uF | 22uF | 22uF | 22uF — matched; VZH220M1HTR-0606L: matched; VES220M1HTR-0605: matched |
| Voltage | 50V | 50V | 50V | 50V | 50V — matched; VZH220M1HTR-0606L: matched; VES220M1HTR-0605: matched |
| Endurance | 2000h | 2000h @ 105°C | 2000-5000h | 1000h | 2000h @ 105°C / 2000-5000h / 1000h — Load life matches target.; VZH220M1HTR-0606L: Equal or better lifetime.; VES220M1HTR-0605: Lifetime is half of the target's 2000h. |
Verified drop-in options for EFVH050ADA220M0654 are limited in the current batch. Review candidates marked Strong match or Datasheet verified, and validate package, pinout, and electrical limits before committing a BOM change.
