Crystals Procurement Notes

Verify the specific suffix and packaging configuration against official distributor catalogs to ensure compatibility with automated assembly processes. Confirm that the requested quantity aligns with standard reel or cut-tape availability constraints. Cross-reference the manufacturer part number with the latest datasheet revisions to validate current RoHS compliance status and material composition declarations prior to final procurement authorization.

Crystals Selection Notes

Select this component when a 25 MHz reference signal is required within a strict spatial envelope defined by the 3.2 x 2.5 mm footprint. Ensure the target circuit design accommodates the specified 18 pF load capacitance to maintain accurate frequency performance. Verify that the operational environment remains within the -40°C to +85°C thermal range to guarantee the stated ±30 ppm stability metrics are achieved throughout the product lifecycle.

Crystals Part Context

This model belongs to the 7M series of surface-mount crystals from TXC Corporation. The series is characterized by its use of seam sealing techniques to enhance durability and reliability compared to standard epoxy-sealed units. These components are engineered for high-volume manufacturing environments where consistent quality and precise frequency control are critical for system synchronization.

Crystals Replacement Considerations

Direct substitutes include other 25 MHz SMD crystals with identical 3.2x2.5mm footprints and 18pF load requirements. Verify pinout compatibility and ESR specifications before implementation.
