Crystals Procurement Notes

Verify component authenticity through authorized channels. Confirm RoHS3 compliance status as indicated in official documentation. Ensure storage conditions maintain moisture sensitivity level 1 integrity prior to soldering. Cross-reference datasheet specifications against design requirements to validate electrical parameters.

Crystals Selection Notes

Select this component when a 20 MHz fundamental frequency with 9 pF load capacitance is required. Consider the ±10 ppm tolerance for precision timing needs. Evaluate the 4-SMD package size constraints against PCB layout limitations. Verify thermal operating range suitability for the target environment.

Crystals Part Context

This part belongs to the CTS 402 series of surface-mount crystals. It shares the same physical footprint and general electrical characteristics as variants like 402F200XXCKT, differing primarily in load capacitance and tolerance specifications. The series provides standardized SMD solutions for frequency control.

Crystals Replacement Considerations

Direct substitutes include 402F20012IKR and 402F20012IAR, though these differ in load capacitance (8pF and 10pF respectively). Verify circuit compatibility before substitution due to varying load capacitance values affecting oscillator stability.
