Crystals Procurement Notes

Verify the specific load capacitance requirement against your circuit design, as the 402F5001XIJR specifies 8pF. Confirm that the 60 Ohm ESR limit aligns with your oscillator circuit's drive level constraints. Ensure the 4-SMD footprint matches your board layout. Check for any specific reflow soldering profile requirements provided in the official datasheet to maintain component integrity during assembly.

Crystals Selection Notes

Select this component when a 50 MHz reference with tight ±10 ppm accuracy is required. Consider the 8pF load capacitance compatibility with your oscillator circuit. Evaluate the 4-SMD package size against available board space. Compare the 60 Ohm ESR against other options if lower impedance is needed for specific drive levels. Verify temperature stability meets application demands.

Crystals Part Context

This part belongs to the CTS 402F series of surface-mount crystals. It is distinct from variants like the 402F50022IJR which offers ±20 ppm tolerance and 9pF load capacitance. The 402F5001XIJR specifically targets applications requiring tighter frequency accuracy than standard ±20 ppm parts. It shares the same physical footprint but differs in electrical specifications compared to other members of the family.

Crystals Replacement Considerations

Direct substitutes include the 402F5001XIKT, which shares identical electrical parameters but may differ in packaging suffix or reel configuration. Cross-reference the 402F5001XIAR if alternative leaded or tape-and-reel options are needed. Always verify pinout and mechanical dimensions before substitution.
