Crystals Procurement Notes

This component is listed as obsolete or end-of-life by the manufacturer. Verification of current availability requires direct consultation with authorized distributors or secondary market suppliers. Procurement planning should account for potential supply chain limitations associated with discontinued part numbers. Alternative sourcing strategies may be necessary to maintain production continuity.

Crystals Selection Notes

Engineers selecting this component must verify compatibility with circuit requirements for parallel resonance mode and 20 pF load capacitance. The ±50 ppm frequency tolerance should be assessed against system jitter and phase noise specifications. Due to the through-hole package type, PCB layout constraints regarding hole size and mechanical stress relief must be considered during the design phase.
