Crystals Procurement Notes

Verify the exact load capacitance requirements against the target oscillator circuit design before procurement. Confirm that the integrated resistor values align with the drive level specifications of the host system. Ensure the HC-49/U footprint matches the PCB layout constraints. Cross-reference the full part number to confirm the specific tolerance and temperature coefficient grades available from authorized distributors.

Crystals Selection Notes

Select this component when a stable 200 kHz reference is required in a standard through-hole format. Consider the integrated resistor feature if board space for external components is limited or if simplified assembly processes are prioritized. Evaluate the operating temperature range against the environmental conditions of the final application to ensure long-term frequency stability.

Crystals Part Context

This part belongs to the CTS 402 series of crystal units, which are widely used in general-purpose timing applications. The series offers various frequency options and package styles. The 402F200XXCKT specifically addresses low-frequency timing needs where fundamental mode operation provides better stability than overtone modes at this frequency range.

Crystals Replacement Considerations

Direct replacements must match the 200 kHz frequency, HC-49/U package, and integrated resistor configuration. Verify equivalent parts from other manufacturers offer identical electrical characteristics and mechanical dimensions to ensure compatibility with existing tooling and PCB layouts.
