Crystals Procurement Notes

Verify the complete part number against manufacturer documentation to ensure correct suffixes for tolerance, packaging, and lead finish. Confirm that the specific variant matches the required load capacitance and ESR specifications for the target circuit design. Cross-reference the datasheet revision date to ensure compliance with current RoHS and REACH directives. Validate supplier authorization to guarantee genuine components.

Crystals Selection Notes

Select this component when a low-profile, fundamental frequency crystal is required for 27MHz applications. Ensure the host circuit provides the specified 18pF load capacitance to maintain accuracy within ±20ppm. Consider the 2.5x2.0mm footprint for board space optimization. Verify thermal requirements against the -40°C to +85°C operational range. Check ESR limits against oscillator circuit drive level constraints.

Crystals Part Context

This model belongs to TXC's general-purpose surface-mount crystal oscillator lineup designed for cost-sensitive consumer and industrial applications. The 7V series emphasizes miniaturization while maintaining standard electrical characteristics. It serves as a timing reference where moderate stability suffices. The product line supports high-volume manufacturing through standardized surface-mount packaging.

Crystals Replacement Considerations

Direct substitutes include other 27MHz fundamental SMD crystals with identical 2.5x2.0mm footprints and 18pF load capacitance. Verify pinout compatibility and ESR ranges before substitution. Alternative packages require mechanical redesign. Ensure frequency stability and temperature coefficients match application requirements.
