Crystals Procurement Notes

Verify that the specific ordering suffix matches the required load capacitance, as variants exist with different electrical specifications. Confirm RoHS compliance status through official documentation prior to integration. Ensure the selected variant aligns with the target application's thermal requirements and physical layout constraints. Cross-reference datasheet parameters against design specifications to prevent mismatched impedance or frequency accuracy issues during production.

Crystals Selection Notes

Select this component when a small form factor is critical for the PCB layout. Consider the 1.2 pF load capacitance default if the host circuitry matches this value; otherwise, verify alternative suffixes for different capacitance needs. Evaluate the ±20 ppm tolerance against system timing requirements. Ensure the -40°C to +85°C range covers the operational environment. Compare ESR values against oscillator drive level limits to ensure reliable startup.

Crystals Part Context

This part belongs to the VMK3 family of tuning fork crystals from Microchip Technology. These components are engineered for low-power, high-reliability timing solutions. The series offers various package options and electrical configurations to support diverse embedded applications. The VMK3-9005 variant specifically targets ultra-compact designs where board space is limited while maintaining industry-standard frequency accuracy.

Crystals Replacement Considerations

Direct substitutes include other Microchip VMK3 series parts with matching frequency and package dimensions but potentially different load capacitances. Verify equivalent electrical parameters such as frequency tolerance and aging rate before substitution. Ensure any replacement maintains the same CDFP-2 footprint and pin configuration to avoid PCB redesign.
