Procurement Notes

Verify part availability status as DigiKey lists this item as discontinued or no longer provided. Confirm current stock levels with authorized distributors before finalizing procurement plans. Check for potential supply chain limitations or uncertain lead times associated with end-of-life components. Ensure ordering suffixes match specific packaging requirements if available from remaining inventory sources.

Selection Notes

Select this component when a 6.144 MHz fundamental frequency is required for circuit timing applications. The 30 pF load capacitance must match the oscillator circuit design specifications. Consider the HC-49/4H package dimensions for PCB layout constraints. Verify that the ±30 ppm tolerance meets the system's frequency accuracy requirements within the specified operating temperature range.
