Crystals Procurement Notes

Verify the specific suffix and revision level against the manufacturer's current datasheet to ensure compatibility with design requirements. Confirm RoHS compliance status and lead-free specifications prior to integration. Check for any recent product discontinuance notifications or lifecycle changes that may affect long-term availability and supply chain stability.

Crystals Selection Notes

Select this component when a 20 MHz reference with 8 pF load capacitance is required for space-constrained designs. Ensure the application circuit matches the specified 50 Ohm ESR and 100 uW drive level limits. Validate that the -20°C to +70°C operating range meets the environmental conditions of the target system.

Crystals Part Context

This part belongs to the 7A series of surface mount crystals from TXC Corporation. These components are designed for general-purpose timing applications where standard size and performance are sufficient. The series offers various frequency options within the same physical footprint to simplify inventory management.

Crystals Replacement Considerations

Direct substitutes include other 20 MHz SMD crystals with identical 8 pF load capacitance and 5x3.2mm dimensions. Verify pinout compatibility and electrical parameters such as ESR and frequency stability before swapping.
