Crystals Procurement Notes

Verify the specific ordering suffix to ensure the correct package variant and termination finish match the design requirements. Confirm that the ±20ppm frequency tolerance aligns with the system's phase noise and jitter specifications. Check the manufacturer's standard lead time, which may vary based on production schedules. Ensure the selected quantity matches the available tape and reel packaging standards to avoid handling discrepancies during assembly.

Crystals Selection Notes

Select this component when a 10 MHz reference is required in a compact surface-mount form factor. The HC-49/US-SM package offers a balance between electrical performance and board space efficiency. Consider the ±20ppm stability limit against the oscillator circuit's total allowable error budget. Verify compatibility with the target PCB layout dimensions, specifically the 5.00mm x 3.20mm footprint and 1.43mm height constraint.

Crystals Part Context

This part belongs to the CTS 435 Series of surface-mount crystals, engineered for general-purpose timing applications. It serves as a direct replacement for through-hole HC-49/U crystals where space constraints necessitate a surface-mount solution. The series provides consistent electrical characteristics across various frequencies, supporting designs in consumer electronics, industrial controls, and telecommunications infrastructure.

Crystals Replacement Considerations

Direct substitutes include the TS192F33CET for different frequency requirements or the 435F28622IET for alternative frequency options within the same package family. Verify pin compatibility and electrical parameters before substitution.
