Crystals Procurement Notes

Verify the specific suffix code against official manufacturer documentation to confirm exact electrical tolerances and packaging configurations. Ensure that the selected variant matches the required load capacitance and frequency stability parameters for the target application design. Cross-reference the datasheet revision history to validate current production status and compliance certifications before finalizing procurement orders.

Crystals Selection Notes

Select this component when a compact 3225 footprint is required for space-constrained printed circuit board layouts. Consider the ±10 ppm tolerance requirement relative to system timing accuracy needs. Evaluate the 12 pF load capacitance compatibility with the host oscillator circuit design. Confirm that the standard industrial temperature range meets the environmental operating conditions of the end product.

Crystals Part Context

This part belongs to the E3X series of surface-mount crystal resonators from Eaton Electronics. The series offers various frequency options and package sizes to support diverse electronic design requirements. The E3X250121YA2 specifically addresses applications needing a reliable 25 MHz reference signal in a standardized small outline package format suitable for high-volume manufacturing environments.

Crystals Replacement Considerations

Direct substitutes include other 25 MHz, 12 pF, ±10 ppm crystal resonators in the 3225 package from manufacturers such as Epson or Murata. Verify pinout compatibility and equivalent electrical parameters before substitution. Alternative Eaton variants within the same series may offer different tolerance grades or temperature ranges.
