EPSON
Needs validationmedium risk
Strong functional alternative with better ESR, but requires a different PCB layout (3.2x1.5mm vs 2.05x1.2mm).
Best Alternatives to X1A0000610006
The EPSON X1A0000610006 is a 32.768 kHz crystal in a compact 2.05x1.2mm SMD package for real-time clocks. Finding a direct replacement requires matching the 7pF load capacitance and package footprint.
AI replacement insight
Package riskhigh
Many alternatives use a different package, requiring a board spin.
Electrical riskmedium
Load capacitance and ESR differences require circuit validation to ensure frequency accuracy and startup.
Can it be replaced directly?
No direct drop-in replacement with identical key parameters was found. Alternatives require either circuit modification for different electricals or a PCB layout change for a different package.
Best replacement path
For new designs, use EPSON X1A0001410006 for better ESR, but note the larger package. For existing boards, evaluate EPSON X1A0000610002 but verify circuit compatibility.
Main risk
The primary risk is mismatch in load capacitance and package footprint, which can cause frequency errors or prevent assembly.
