Best Alternatives to X321532768KGD2SI
X321532768KGD2SI is a 32.768kHz 12.5pF SMD3215 crystal. Closest candidates match frequency and load, but pinout and datasheets still need review.
AI replacement insight
Electrical riskmedium
CL, ESR, and shunt capacitance affect oscillation margin.
Package riskmedium
3215 suffix and land pattern need confirmation.
Firmware risklow
Passive crystal normally needs no firmware change.
Sourcing riskmedium
Lifecycle data is incomplete for several candidates.
Can it be replaced directly?
Direct replacement for X321532768KGD2SI should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
Start with XKXGI-SUA-32.768K, then verify pinout, footprint, shunt capacitance, and datasheet limits.
Main risk
Load capacitance or footprint differences can shift RTC accuracy or affect assembly.
