Is there a pin-compatible replacement for LQH32CN4R7M33L?

Yes, several parts like the Murata DFE322512F-4R7M=P2 use the same 1210 package and 2-pin layout. However, always verify the land pattern and electrical parameters like DCR before production.

What risks should I check before replacing LQH32CN4R7M33L?

Key risks include differences in DC Resistance (DCR), which affects efficiency, and current saturation (Isat). Also verify the substitute's tolerance and self-resonant frequency (SRF) meet your circuit's requirements.

Finding a substitute for the Murata LQH32CN4R7M33L 4.7µH inductor involves matching its 1210 package, 650mA current rating, and 150mΩ DCR. Several alternatives exist with varying performance trade-offs.

AI replacement insight

Electrical risklow

Key electricals are similar or better on top candidates, but DCR must always be checked.

Package risklow

Several candidates match the 1210 package, but non-matching packages were rejected.

Sourcing riskmedium

Availability and pricing of alternatives should be verified with distributors.

Can it be replaced directly?

A direct, drop-in replacement is likely with DFE322512F-4R7M=P2, as it matches the 1210 package and key electricals while offering better performance.

Best replacement path

The recommended path is an upgrade to a modern power inductor like DFE322512F-4R7M=P2, which offers superior current handling in the same package.

Main risk

The main risk when substituting is an increase in DC Resistance (DCR), which can reduce power efficiency. Candidates with different package sizes are not drop-in replacements.

Recommended alternatives

An upgrade with much higher current rating and wider temperature range in the same 1210 package.
