Crystals Procurement Notes

Verify the specific suffix 'K' against official Epson documentation to confirm the exact frequency tolerance and packaging configuration. Ensure the design accounts for the 10pF load capacitance requirements of the host oscillator circuit. Cross-reference the 40 Ohm ESR with the application schematic to guarantee reliable startup conditions under all environmental conditions.

Crystals Selection Notes

Select this model when ±20 ppm stability is required across a wide -40°C to +85°C range. Choose the 10pF load capacitance variant if the host circuit matches this specification. Consider the 4-SMD package for automated surface-mount assembly processes. Verify that the 30 MHz frequency aligns with the system timing requirements before finalizing the component selection.

Crystals Part Context

This component belongs to the Epson FA-238 series of crystal units, designed for general-purpose timing applications. The series offers various frequency options and tolerance levels within a standardized small outline package. The FA-238 line is recognized for its reliability and consistency in consumer, industrial, and automotive electronics requiring precise clock signals.

Crystals Replacement Considerations

Direct substitutes must match the 30 MHz frequency, 10pF load capacitance, 40 Ohm ESR, and ±20 ppm stability. Compatible alternatives include other manufacturers' 3225-sized crystals with identical electrical parameters. Verify pin compatibility and thermal characteristics when replacing with cross-brand components.
