Crystals Procurement Notes

Verify the specific suffix 'CKT' against the manufacturer's official datasheet to confirm the tape and reel packaging configuration and exact electrical tolerances. Ensure the design-in process accounts for the specified load capacitance of 8pF to maintain frequency accuracy within the ±15ppm limit. Check current availability status as distribution channels may list discontinued or backorder statuses that differ from immediate stock availability.

Crystals Selection Notes

Select this component when a 20 MHz fundamental crystal with ±15ppm stability is required for space-constrained designs. The 4-SMD package size suits high-density PCB layouts. Verify that the application circuit provides the necessary 8pF load capacitance to match the crystal's specification. Confirm that the operating temperature range of -20°C to +70°C aligns with the environmental conditions of the target system.

Crystals Part Context

This part belongs to the CTS 402 Series of surface-mount crystals. The series offers various frequency options and package sizes tailored for consumer and industrial electronics. The 402F20033CKT specifically utilizes the standard 4-SMD footprint common in modern SMT manufacturing lines, ensuring compatibility with existing pick-and-place equipment used for similar components in the same product family.

Crystals Replacement Considerations

The 402F200XXCKT is listed as a related variant in distributor databases but lacks explicit functional equivalence confirmation. Direct substitution requires verifying identical frequency, load capacitance, ESR, and package dimensions against the original design specifications. Cross-referencing with the manufacturer's official replacement guide is necessary to ensure performance parity.
