Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure alignment with required stability, resistance, and load capacitance parameters. Confirm that the tape and reel packaging option matches production line requirements. Cross-reference the part number with official distributor catalogs to validate authenticity and current availability status before finalizing procurement orders.

Crystals Selection Notes

Select this component when a compact surface mount footprint is required alongside high-temperature resilience up to 125°C. The 70 Ohm ESR and 18 pF load capacitance must match the oscillator circuit design constraints. Ensure the ±20 ppm tolerance meets the system's clock accuracy requirements compared to looser tolerance alternatives within the CX5 series.

Crystals Part Context

This part belongs to the Cardinal CX5 series of ceramic surface mount crystals. The series offers various package sizes and electrical configurations. The CX5Z variant specifically denotes tape and reel packaging. This model represents a standard fundamental mode crystal optimized for general-purpose digital timing applications requiring reliable performance across broad thermal conditions.

Crystals Replacement Considerations

Direct substitutes include other Cardinal CX5 series parts with matching 7.0x5.0mm dimensions and 8.0MHz frequency. Verify equivalent ESR and load capacitance values when cross-referencing with competitor brands such as Abracon or NDK to ensure circuit compatibility without redesign.
