Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct specifications. Confirm that the requested variant matches the required load capacitance and frequency tolerance. Check for any recent product change notices or design revisions that may affect compatibility. Ensure the procurement channel provides valid traceability documentation. Validate that the component meets RoHS compliance requirements for your manufacturing process.

Crystals Selection Notes

Select this component when a 20 MHz fundamental frequency with tight ±10 ppm stability is required. Ensure the circuit design accommodates a 10 pF load capacitance and 60 Ohm ESR. Verify that the 4-SMD footprint fits within the available board space constraints. Consider the operating temperature range limits for the intended application environment. Compare against alternative crystals if different load capacitances are necessary for the oscillator circuit.

Crystals Part Context

This component belongs to the CTS Frequency Controls crystal family, specifically designed for surface-mount technology. It serves as a passive frequency-determining element in electronic circuits. Unlike active oscillators, it requires an external oscillator circuit to generate a signal. The 403 series typically offers robust performance for general-purpose timing applications.

Crystals Replacement Considerations

Public confirmed substitute part numbers include 405C11A20M00000 and 403C35D20M00000. Verify electrical parameters such as load capacitance and ESR before substitution. Ensure mechanical dimensions and pin configurations are compatible with the existing footprint.
