Crystals Procurement Notes

Verify the specific load capacitance and ESR requirements against the target circuit design before procurement. Confirm that the surface-mount footprint matches the PCB silkscreen and pad layout. Ensure the operating temperature range meets the environmental specifications of the final application to guarantee long-term frequency stability.

Crystals Selection Notes

Select this component when a 6 MHz surface-mount crystal with 22 pF load capacitance is required. Compare the ESR value against the oscillator circuit's drive level limitations. Consider the physical dimensions of the HC-49/US SMD variant relative to available board space. Validate compatibility with the host device's input impedance characteristics.

Crystals Part Context

This part belongs to the 049SS2 series of surface-mount crystals from Suzhou Hangjing. The series offers various frequencies and load capacitances within the HC-49/US form factor. These components are designed for general-purpose timing applications where moderate accuracy and standard package size are sufficient. The manufacturer specializes in quartz frequency control units established in 2014.

Crystals Replacement Considerations

Direct substitutes must match the 6 MHz frequency, 22 pF load capacitance, and HC-49/US SMD package. Verify ESR compatibility with the existing oscillator circuit. Cross-reference pinout and mechanical dimensions to ensure board-level interchangeability without rework.
