Crystals Procurement Notes

Verify the specific suffix configuration against the manufacturer datasheet to ensure compatibility with required load capacitance and tolerance specifications. Confirm RoHS compliance status and moisture sensitivity level prior to integration into production workflows. Cross-reference the part number with official distributor catalogs to validate current availability and lead times.

Crystals Selection Notes

Select this component when a standard 40 MHz reference is required for space-constrained designs utilizing the 3.2x2.5 mm package. Ensure the target circuit provides the specified 12 pF load capacitance to maintain accurate frequency performance. Consider the ESR value relative to the oscillator circuit drive level requirements.

Crystals Part Context

This part belongs to the 7M series of quartz crystals from TXC Corporation, which focuses on general-purpose surface-mount components. The series offers various frequency options within standardized package dimensions to facilitate design reuse across different product lines.

Crystals Replacement Considerations

Direct substitutes include other 40 MHz crystals in the 3.2x2.5 mm SMD package with matching 12 pF load capacitance and similar ESR characteristics. Verify pinout compatibility and mounting dimensions before substitution.
