A functional upgrade with higher current ratings and lower DCR, but in a different, larger package.
The XR0630-470M is a compact 47µH molded power inductor designed for high-current DC/DC converters. While no direct drop-in replacements are available, several functional upgrades exist for new designs.
All potential upgrades are in much larger packages, requiring a complete board redesign.
Candidates offer superior current ratings and lower DCR, reducing electrical stress.
Alternatives are from different manufacturers, requiring vendor qualification.
No direct, drop-in replacement for the XR0630-470M was found. All reviewed alternatives have different physical packages that are not compatible with the existing footprint.
Consider electrical upgrades like SDRI127-470MT or FXC1040-470M if a board redesign is feasible, as they offer significantly higher current handling and lower DCR.
The primary risk is the significant package mismatch between the target and all viable alternatives, which necessitates a new PCB layout and mechanical verification.

| Feature / factor | XR0630-470M | FXC1040-470M | FXL1350-470-M | SDRI127-470MT | Compatibility / risk |
|---|---|---|---|---|---|
| Package | 0630 (approx 6.3x6.3mm) | 11.5mm x 10.3mm | 13.45mm x 12.6mm | 12.5mm x 12.5mm | 11.5mm x 10.3mm / 13.45mm x 12.6mm / 12.5mm x 12.5mm — Candidate is significantly larger and not a drop-in replacement.; FXL1350-470-M: Candidate is significantly larger and not a drop-in replacement.; SDRI127-470MT: Candidate is significantly larger and not a drop-in replacement. |
| Inductance | 47 µH | 47 µH | 47 µH | 47 µH | 47 µH — matched; FXL1350-470-M: matched; SDRI127-470MT: matched |
| Saturation Current A | 2.0 A | 4.5 A | 5.0 A | 4.6 A | 4.5 A / 5.0 A / 4.6 A — Higher saturation current provides more margin.; FXL1350-470-M: Higher saturation current provides more margin.; SDRI127-470MT: Higher saturation current provides more margin. |
| Current A | 1.5 A | 3.0 A | 2.6 A | 2.5 A | 3.0 A / 2.6 A / 2.5 A — Higher RMS current rating.; FXL1350-470-M: Higher RMS current rating.; SDRI127-470MT: Higher RMS current rating. |
| Dcr Ohm | 0.385 Ω | 0.167 Ω | 0.13 Ω | 0.1 Ω | 0.167 Ω / 0.13 Ω / 0.1 Ω — Lower DCR improves efficiency.; FXL1350-470-M: Lower DCR improves efficiency.; SDRI127-470MT: Lower DCR improves efficiency. |
No direct drop-in replacement was found. However, parts like SDRI127-470MT and FXC1040-470M are excellent electrical upgrades with higher current ratings if your design can accommodate a larger package size.
