Is there a pin-compatible replacement for LQH32CN220K23L?

The Murata LQH32PN220MN0L shares the same 1210 package and pinout, making it a likely pin-compatible candidate. However, due to electrical differences like tolerance, full drop-in compatibility requires engineering review.

What risks should I check before replacing LQH32CN220K23L?

Key risks include changes in inductance tolerance, which can affect filter performance or regulator stability, and differences in Self-Resonant Frequency (SRF). Always verify the substitute's package dimensions and land pattern match your PCB layout.

AI replacement insight

Electrical riskmedium

Tolerance and SRF changes require analysis.

Package risklow

Same-package options exist, but near-matches require layout check.

Sourcing risklow

Alternatives are from major manufacturers.

Can it be replaced directly?

No direct drop-in replacement has been verified. The closest candidate, LQH32PN220MN0L, has a wider inductance tolerance (±20% vs ±10%) that requires engineering validation.

Best replacement path

The most promising path is using another Murata inductor like LQH32PN220MN0L, which offers upgraded current handling in the same package but requires accepting a wider tolerance.

Main risk

The primary risk is the wider inductance tolerance (±20%) of most alternatives, which could impact the performance of sensitive circuits like filters or DC-DC converters.

Recommended alternatives

Functional alternative in the same 1210 package with higher current rating but wider inductance tolerance.
