Procurement Notes

Verify the specific package variant and tolerance grade against the official datasheet before procurement. Confirm that the application circuit matches the specified load capacitance of 18 pF to ensure accurate frequency performance. Check for any recent part number revisions or lifecycle notices from the manufacturer to avoid obsolescence risks during production.

Selection Notes

Select this component when a 27 MHz fundamental frequency is required in a compact surface-mount form factor. Ensure the PCB layout accommodates the 5.00 mm x 3.20 mm footprint and the 1.00 mm height constraint. Verify that the driving circuit can support the 100 Ohm ESR and 1 mW drive level specifications without overdriving the crystal.

Part Context

This crystal is part of the CFPX-104 series from IQD Frequency Products, designed for general-purpose timing applications. It serves as a standard frequency reference in embedded systems where space constraints necessitate surface-mount technology. The component provides reliable oscillation for digital logic and communication interfaces requiring stable clock signals.

Replacement Considerations

Substitutes must match the 27 MHz frequency, 18 pF load capacitance, and 5.00 x 3.20 mm SMD package. Verify ESR and drive level compatibility to maintain circuit stability.
