Crystals Procurement Notes

Verify the active lifecycle status and RoHS compliance details directly from the manufacturer before procurement. Confirm that the 2-SMD package dimensions align with the target PCB footprint. Ensure the 10 pF load capacitance matches the oscillator circuit requirements to maintain the specified ±15 ppm accuracy.

Crystals Selection Notes

Select this component when a cost-effective, standard-performance crystal is required for 25 MHz applications. The 50 Ohm ESR and 10 pF load capacitance are critical parameters for matching specific oscillator topologies. Consider the ±15 ppm tolerance against the system's frequency stability requirements.

Crystals Part Context

This part belongs to the TXC 7A series of fundamental-mode crystals. It serves as a basic timing element for digital systems requiring precise frequency references. The no-lead SMD format facilitates modern high-volume manufacturing techniques.

Crystals Replacement Considerations

Lower-cost alternatives within the same family may be available. Verify electrical equivalence regarding frequency, load capacitance, and ESR before substitution.
