Procurement Notes

Verify part authenticity through authorized distributors or direct manufacturer channels. Confirm that the specific ordering suffix matches the required packaging format, as revisions may exist. Check current lifecycle status, as this component has been identified as obsolete or end-of-life in some listings. Ensure compatibility with existing PCB footprints and voltage requirements before finalizing procurement decisions.

Selection Notes

Select this oscillator when a 40 MHz reference with moderate stability is required. Consider the ±50 ppm tolerance against application needs. Verify that the 5V supply range aligns with system power rails. Evaluate the 7x5 mm footprint against available board space. Compare performance against alternative frequencies if system requirements allow flexibility in clock speed selection.

Part Context

This component belongs to the CFPS-72 series of standard oscillators produced by IQD Frequency Products. The series offers various frequency options in a consistent 7x5 mm SMD package. These devices are designed for general timing applications where reliable clock signals are essential. The LFSPXO018739 specifically provides the 40 MHz variant within this product family line.

Replacement Considerations

Check for updated part numbers from IQD Frequency Products, as previous identifiers may have changed. Verify equivalent specifications from other manufacturers if original supply is unavailable. Ensure replacement components match the 7x5 mm package dimensions and 40 MHz frequency requirement.
