Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required load capacitance and tolerance specifications. Confirm that the package dimensions match the target footprint design. Request official documentation to validate frequency stability parameters under intended thermal conditions before finalizing procurement decisions.

Crystals Selection Notes

Select this component when a 20 MHz timing source is required with strict frequency accuracy constraints. Ensure the host circuit provides the necessary 8 pF load capacitance to maintain specified performance. Evaluate the 200 Ohm ESR against the oscillator circuit's drive level requirements to prevent overdriving the crystal element during operation.

Crystals Part Context

This part belongs to the SCTF SMD crystal family designed for general-purpose timing applications. It shares common packaging standards with other frequencies in the series, allowing for potential supply chain flexibility if frequency adjustments are permissible. The model designation indicates specific electrical characteristics unique to the 20 MHz variant within the broader product line.

Crystals Replacement Considerations

Direct substitutes must match the 20 MHz frequency, 8 pF load capacitance, and 4-SMD package. Verify equivalent ESR and stability ratings from alternative manufacturers to ensure circuit compatibility without redesign.
