Is there a pin-compatible replacement for SLO0420H100MTT?

Based on the candidates reviewed, no pin-compatible replacement with a matching 4x4mm footprint has been identified. All candidates had different package sizes, requiring a PCB redesign.

What risks should I check before replacing SLO0420H100MTT?

Key risks are package mismatch requiring PCB redesign, and reduced maximum operating temperature. Ensure the alternative's temperature range (e.g., 125°C) is sufficient for your application, as the original is rated to 150°C.

AI replacement insight

Package riskhigh

All viable candidates have a different footprint, requiring a board spin.

Electrical riskmedium

Temperature range is a common downgrade risk that requires application-specific analysis.

Can it be replaced directly?

No, a direct drop-in replacement for SLO0420H100MTT was not found. All reviewed candidates require significant engineering review and likely a PCB redesign.

Best replacement path

Search for a 10µH inductor in a 4x4mm package with current ratings ≥ 2.2A and a temperature range up to 150°C.

Main risk

The primary risks are physical incompatibility due to different package sizes and thermal risk from alternatives with a lower maximum operating temperature.

Recommended alternatives

A functional alternative with higher current ratings and lower resistance, but requires a new PCB layout and has a lower max operating temperature.
