Is there a pin-compatible replacement for SLW6045S220MST?

DMBJ's PNLS6045-220M 22UH shares the same 6045 package but is not a guaranteed pin-compatible replacement. Its higher DC resistance and unverified RMS current require careful engineering review.

What risks should I check before replacing SLW6045S220MST?

Key risks are: 1) Higher DC Resistance (DCR), which increases power loss. 2) Mismatched RMS current rating (Irms), which affects thermal performance. 3) Physical package differences, which require PCB layout changes.

AI replacement insight

Electrical riskmedium

DCR mismatch and missing RMS current data on a key candidate.

Package riskhigh

Some alternatives have completely different packages requiring redesign.

Can it be replaced directly?

No verified direct drop-in replacement has been identified. PNLS6045-220M 22UH is a strong candidate but requires engineering review due to a higher DCR.

Best replacement path

For a potential drop-in, review DMBJ's PNLS6045-220M 22UH, but verify its RMS current and accept a higher DCR.

Main risk

The main risk is increased power loss and heat due to higher DC Resistance (DCR) in potential alternatives.

Recommended alternatives

Form-fit candidate with matching inductance and higher saturation current, but has higher DCR and needs RMS current verification.
