Needs validationhigh risk
A functional alternative with the same 40MHz frequency and package, but requires review due to a different load capacitance.
Best Alternatives to TXM40M0004252HBCEO00T
TXM40M0004252HBCEO00T is a 40MHz crystal in a 2.5x2.0mm package. Finding a direct drop-in replacement requires careful matching of load capacitance and frequency stability.
AI replacement insight
Electrical riskhigh
Load capacitance mismatch requires circuit validation.
Package risklow
Package dimensions are consistent across candidates.
Firmware risklow
Not applicable for a passive crystal.
Can it be replaced directly?
Direct replacement for TXM40M0004252HBCEO00T should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
Consider parametric alternatives like TZ1181EAAA32, but be prepared to validate and potentially adjust the oscillator circuit due to differing load capacitance.
Main risk
The primary risk is mismatch in load capacitance, which can cause frequency deviation or failure to oscillate.
