Offers higher current and lower resistance in a larger, non-compatible package.
Finding a substitute for the DMBJ PNLS6045-680M 68UH power inductor involves balancing electrical performance and physical compatibility. While several alternatives offer superior current handling and lower resistance, they are not drop-in replacements due to different package sizes, requiring careful design consideration.
All reviewed alternatives have different, larger packages, requiring a new PCB layout.
Candidates offer superior current handling and lower DCR, but circuit interaction should be verified.
Direct replacement for PNLS6045-680M 68UH should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
For new designs or board revisions, consider electrically superior parts like SMMS1350-680M. For existing boards, no drop-in replacement was found.
Package mismatch is the primary risk, preventing drop-in replacement and requiring a PCB redesign.

| Feature / factor | PNLS6045-680M 68UH | SMDRH104R-680MT | SMMS1050-680M | SMMS1350-680M | Compatibility / risk |
|---|---|---|---|---|---|
| Package | 6045 (6.0x6.0mm) | 10.3x10.3mm | 1050 (~10x10mm) | 1350 (13.8x12.6mm) | 10.3x10.3mm / 1050 (~10x10mm) / 1350 (13.8x12.6mm) — Candidate is larger and not footprint compatible.; SMMS1050-680M: Candidate is larger and not footprint compatible.; SMMS1350-680M: Candidate is significantly larger and not footprint compatible. |
| Inductance | 68µH | 68µH | 68µH | 68µH | 68µH — Inductance matches the target value.; SMMS1050-680M: Inductance matches the target value.; SMMS1350-680M: Inductance matches the target value. |
| Saturation Current | 1.6A | 2.08A | 3.0A | 4.5A | 2.08A / 3.0A / 4.5A — Higher saturation current provides more margin.; SMMS1050-680M: Higher saturation current provides more design margin.; SMMS1350-680M: Higher saturation current provides more design margin. |
| Dcr | 330mΩ | 213mΩ | 190mΩ | 135mΩ | 213mΩ / 190mΩ / 135mΩ — Lower DCR improves efficiency.; SMMS1050-680M: Lower DCR improves efficiency.; SMMS1350-680M: Lower DCR improves efficiency by reducing copper losses. |
Verified drop-in options for PNLS6045-680M 68UH 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.
