Is there a pin-compatible replacement for VLS6045EX-100M?

Based on this review, no pin-compatible (same 6.0x6.0mm footprint and pinout) replacement was identified. All evaluated candidates have different physical dimensions and require board layout modifications.

What risks should I check before replacing VLS6045EX-100M?

The primary risk is the mechanical fit; verify the candidate's package dimensions and land pattern against your PCB layout. Also, check for increased DC Resistance (DCR), which can reduce efficiency and increase heat.

VLS6045EX-100M Alternatives, Datasheet & Cross Reference | TDK Electronics AG

The TDK VLS6045EX-100M is a 10µH shielded power inductor in a 6.0x6.0mm package. Finding a direct drop-in replacement is challenging as most alternatives with similar or better electrical performance come in larger packages.

AI replacement insight

Package riskhigh

All candidates have larger footprints, requiring board redesign.

Electrical riskmedium

Some candidates have significantly higher DCR, impacting efficiency.

Sourcing risklow

Target and most candidates are listed as Active.

Can it be replaced directly?

No direct, drop-in replacement was found. All candidates require a PCB layout change due to package size differences.

Best replacement path

Board redesign for a larger footprint part like SXN SMMS0650-100M, which offers upgraded current ratings.

Main risk

Package mismatch is the primary risk, preventing a direct drop-in replacement.

Recommended alternatives

A functional alternative with superior electrical performance but in a much larger package.
