Crystals Procurement Notes

Verify the specific suffix 'E' in the part number against official datasheets to confirm the exact frequency tolerance and temperature stability specifications. Ensure that the required load capacitance matches the target circuit design to achieve accurate oscillation frequencies. Confirm RoHS compliance status through manufacturer documentation prior to integration.

Crystals Selection Notes

Select this component when a 25 MHz reference is required with high initial accuracy and moderate temperature stability. The 8 pF load capacitance requirement must align with the host system's external capacitor values. Consider the 60 Ohm ESR limit to ensure proper oscillator circuit startup and sustained operation without excessive drive level issues.

Crystals Part Context

This part belongs to the 7M series of commercial-grade quartz crystals from TXC Corporation. The series offers various frequency options and packaging styles designed for general-purpose electronic applications. The 7M series components are characterized by their reliability and consistent performance in standard consumer and industrial electronics environments.

Crystals Replacement Considerations

Direct substitutes include other 25 MHz SMD crystals with identical 3.2x2.5mm dimensions, 8pF load capacitance, and ±10ppm tolerance. Verify pinout compatibility and mounting footprint before swapping. Alternative parts from different manufacturers may require circuit adjustments due to varying ESR or drive level specifications.
