A strong upgrade with higher current ratings and a nearly identical 4.4x4.2mm footprint.
APH0420T2R2M is a 2.2µH power inductor in a compact 4.4x4.2mm SMD package, designed for DC/DC converters. This page reviews potential alternatives, focusing on electrical performance and package compatibility.
Most alternatives have different footprints or heights, requiring layout or clearance verification.
All suggested alternatives offer superior or equal current and DCR ratings.
No verified direct drop-in replacement exists. XR0420-2R2M is a strong candidate but requires verification of its slightly greater height (2.0mm vs 1.8mm).
XR0420-2R2M offers upgraded current ratings in a nearly identical package, making it the strongest candidate.
The primary risk is mechanical incompatibility due to differences in package footprint or height.

| Feature / factor | APH0420T2R2M | XR0420-2R2M | FXL0518-2R2-M | FEXL0430A-2R2M | Compatibility / risk |
|---|---|---|---|---|---|
| Inductance | 2.2µH | 2.2µH | 2.2µH | 2.2µH | 2.2µH — Inductance matches.; FXL0518-2R2-M: Inductance matches.; FEXL0430A-2R2M: Inductance matches. |
| Current | 4.15A | 5.0A | 6.5A | 7.0A | 5.0A / 6.5A / 7.0A — Higher saturation current.; FXL0518-2R2-M: Higher saturation current.; FEXL0430A-2R2M: Higher saturation current. |
| Dcr | 58mΩ | 58mΩ | 35mΩ | 22.6mΩ | 58mΩ / 35mΩ / 22.6mΩ — DC resistance matches.; FXL0518-2R2-M: Lower DCR improves efficiency.; FEXL0430A-2R2M: Lower DCR improves efficiency. |
| Package | 4.4x4.2x1.8mm | 4.4x4.2x2.0mm | 5.4x5.2mm | 4.1x4.1x2.8mm | 4.4x4.2x2.0mm / 5.4x5.2mm / 4.1x4.1x2.8mm — Footprint matches, but slightly taller.; FXL0518-2R2-M: Larger footprint.; FEXL0430A-2R2M: Smaller footprint but significantly taller. |
XR0420-2R2M is the best alternative, offering higher current ratings (5A Isat) in a nearly identical package. However, its slightly greater height (2.0mm vs 1.8mm) requires mechanical verification.
