A very close functional match in a smaller 0805 package, requiring a board layout change.
Best Alternatives to CMP321609XD100MT
CMP321609XD100MT is a 10µH, 300mA power inductor in a 1206 package. While no direct drop-in replacements have been identified, several functional alternatives exist that offer upgraded performance or smaller size, provided a board redesign is feasible.
AI replacement insight
Package riskhigh
No candidates match the 1206 package, requiring mandatory PCB redesign.
Electrical riskmedium
Target's saturation current is unknown. While candidates offer higher rated current, peak current suitability must be verified by the user.
Can it be replaced directly?
No, there are no direct pin-compatible replacements for CMP321609XD100MT among the candidates reviewed. All functional alternatives have different package sizes and require a PCB layout change.
Best replacement path
For a smaller footprint with similar performance, consider SLM2012100MIT (0805). For a significant power handling upgrade, VLS6045EX-100M offers much higher current and lower DCR, but in a large 6x6mm package.
Main risk
The primary risk is the package incompatibility, which necessitates a board redesign. A secondary risk is the unknown saturation current of the original part, requiring users to verify the candidate's Isat against their application's peak current needs.
