NX3215SA-32.768K-STD-MUA-8 is a 32.768 kHz NDK tuning-fork crystal with 12.5 pF load. Alternatives need CL, ESR, footprint, and startup checks.

AI replacement insight

Electrical riskmedium

CL and ESR affect oscillator startup and accuracy.

Package riskmedium

2-SMD class is not enough to prove footprint.

Firmware risklow

Passive crystal usually has no firmware impact.

Sourcing risklow

Kept NDK candidates are Active.

Can it be replaced directly?

Direct replacement for NX3215SA-32.768K-STD-MUA-8 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

Start with same NX3215SA series options, but review load capacitance changes.

Main risk

Load capacitance mismatch can shift RTC accuracy or startup margin.
