Top candidates have matching or better electrical specs.

Package risklow

Candidates share the same 6045 package footprint.

Sourcing riskmedium

Switching manufacturers may have supply chain implications.

Can it be replaced directly?

Direct replacement for SWPA6045S330MT should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

The TDK VLS6045EX-330M is the most promising replacement, offering an upgrade in current handling within the same package.

Main risk

The primary risk when substituting any inductor is ensuring the replacement's dynamic performance and EMI characteristics are acceptable in the circuit.

Recommended alternatives

Strong alternative with same 33µH inductance and 6045 package, offering improved current ratings.
