cjiang (Changjiang Microelectronics Tech)
Offers higher current ratings and lower DCR in a similar footprint, but requires height clearance check.
FXL0518-1R0-M is a 1.0µH power inductor from cjiang in a 5.4x5.2mm package, rated for 7.2A. While no exact drop-in is confirmed, several functional alternatives with similar or better electrical ratings are available.
Several candidates offer superior current handling and lower DCR.
Most candidates have different package dimensions, requiring layout and clearance verification.
No direct, pin-for-pin verified replacement for FXL0518-1R0-M has been identified. The closest candidate, FXL0530-1R0-M, requires package verification.
FXL0530-1R0-M offers upgraded current ratings and lower DCR with a similar footprint, but requires checking for height clearance (3.0mm vs 1.8mm).
The primary risk is package incompatibility, specifically footprint and height differences, which could prevent a drop-in replacement.

| Feature / factor | FXL0518-1R0-M | FXL0530-1R0-M | APH0630T1R0M | FXL1040-1R0-M | Compatibility / risk |
|---|---|---|---|---|---|
| Inductance | 1.0µH | 1.0µH | 1.0µH | 1.0µH | 1.0µH — Inductance matches target.; APH0630T1R0M: Inductance matches target.; FXL1040-1R0-M: Inductance matches target. |
| Package | 5.4x5.2mm | 5.4x4.75mm | 7.0x6.6mm | 11.5mm x 10mm | 5.4x4.75mm / 7.0x6.6mm / 11.5mm x 10mm — Footprint is very similar but height is greater (3.0mm vs 1.8mm).; APH0630T1R0M: Larger package, not a drop-in replacement.; FXL1040-1R0-M: Significantly larger package, not a drop-in replacement. |
| Current | 7.2A | 8.5A | 10.73A | 19.0A | 8.5A / 10.73A / 19.0A — Higher rated current (Irms).; APH0630T1R0M: Higher rated current (Irms).; FXL1040-1R0-M: Higher rated current (Irms). |
| Saturation Current A | 9.0A | 11.0A | 12.45A | 28.0A | 11.0A / 12.45A / 28.0A — Higher saturation current (Isat).; APH0630T1R0M: Higher saturation current (Isat).; FXL1040-1R0-M: Higher saturation current (Isat). |
| Dcr Ohm | 17mΩ | 14mΩ | 7.4mΩ | 0.65mΩ | 14mΩ / 7.4mΩ / 0.65mΩ — Lower DCR improves efficiency.; APH0630T1R0M: Lower DCR improves efficiency.; FXL1040-1R0-M: Significantly lower DCR improves efficiency. |
FXL0530-1R0-M is a strong candidate, offering higher current ratings (8.5A Irms, 11A Isat) and lower DCR (14mΩ). However, its height is 3.0mm, taller than the original's 1.8mm, which must be verified in your application.
