AI replacement insight

Electrical riskmedium

Candidates have variations in voltage range, resistance, or frequency that require review.

Package risklow

All kept candidates are SMD with 2 pins, but physical dimensions should be confirmed via datasheet.

Can it be replaced directly?

No guaranteed drop-in replacement is confirmed. YS-SBZ9032C03R16 is the closest functional match but requires verifying its operating voltage range is compatible with your design.

Best replacement path

YS-SBZ9032C03R16 is the strongest candidate, matching key electricals, but its slightly narrower voltage range (2-4V vs 2.5-4.5V) needs verification.

Main risk

The primary risk is electrical incompatibility due to differences in operating voltage, coil resistance, or resonant frequency, which can affect performance or require circuit modification.

Recommended alternatives

A strong functional match with same frequency and resistance, but a slightly narrower voltage range.
