Is there a pin-compatible replacement for PDMCAT16128-103ML?

PDMCAT16128-502ML shares the same package and pin count, but its inductance is significantly lower (5mH vs 10mH). This is a critical electrical difference and must be evaluated for your specific EMI filtering needs before use.

What risks should I check before replacing PDMCAT16128-103ML?

Key risks include package dimension mismatches requiring board changes, and differences in inductance which will alter EMI filtering performance. Always verify the candidate's datasheet for all parameters, including saturation current and impedance vs. frequency curves.

AI replacement insight

Package riskhigh

One candidate has a different footprint, requiring a board redesign.

Electrical riskmedium

One candidate has 50% lower inductance, impacting EMI filtering.

Can it be replaced directly?

No direct drop-in replacement was found. Alternatives require either a PCB redesign or accepting a significant reduction in inductance.

Best replacement path

For functional equivalence, use PDMCAT18107-103ML and redesign the PCB. For physical compatibility, use PDMCAT16128-502ML but test its reduced filtering.

Main risk

The primary risk is a trade-off between mechanical incompatibility (requiring a board spin) and a significant electrical downgrade (reduced inductance).

Recommended alternatives

Functional alternate with same inductance and current but different package dimensions, requiring board redesign.
