Murata Electronics
A form-fit alternative in a 1210 package with higher current rating but wider tolerance and different shielding.
Finding a replacement for the Murata LQH32CN100K53L 10µH inductor involves balancing package compatibility with electrical parameters. While form-fit options exist, they may have different tolerance or shielding, requiring careful review.
Many functional alternatives have different footprints, requiring a PCB redesign.
Form-fit options often have wider tolerance (±20%) or are shielded, which can affect circuit performance.
10µH inductors in similar packages are widely available from multiple vendors.
No perfect drop-in replacement found. DFE322512F-100M=P2 is the closest form-fit option but has a wider tolerance and is shielded, requiring review.
For existing PCBs, evaluate DFE322512F-100M=P2, accepting the wider tolerance. For new designs, consider a functional alternate like SRP4020TA-100M for superior electricals.
The primary risk is finding a part that is both form-fit (1210 package) and function-fit (matching tolerance, shielding, and electrical ratings).

| Feature / factor | LQH32CN100K53L | DFE322512F-100M=P2 | SRP4020TA-100M | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Package | 1210 (3225 metric) | 1210 (3225 metric) | 4020 | 1210 (3225 metric) / 4020 — Form-fit compatible.; SRP4020TA-100M: Different footprint (4.0x4.0mm) requires PCB redesign. | |
| Current | 0.45 A | 1.1 A | 1.8 A | 1.1 A / 1.8 A — Higher current rating is a safe upgrade.; SRP4020TA-100M: Significantly higher current rating. | |
| Dcr | 0.39 Ω | 0.324 Ω | 0.243 Ω | 0.324 Ω / 0.243 Ω — Lower DCR reduces power loss.; SRP4020TA-100M: Lower DCR reduces power loss. | |
| Tolerance | ±10% | ±20% | - | ±20% — Wider tolerance may affect circuit precision. | |
| Shielding | No Shield | Shielded | - | Shielded — Target is unshielded; may affect EMI/cost. |
DFE322512F-100M=P2 is a strong candidate in the same 1210 package with higher current rating, but has a wider tolerance (±20%) and is shielded. For new designs, parts like SRP4020TA-100M offer better electrical performance in a different package.
