Procurement Notes

Verify the specific ordering suffix and packaging configuration directly with the manufacturer or authorized distributors before procurement. Confirm that the requested quantity aligns with available factory order requirements and current supply chain constraints. Ensure compliance with RoHS directives and verify the exact datasheet version matches the production batch specifications.

Selection Notes

Select this component when a stable 8 MHz reference is required for space-constrained designs. The CFPX-104 footprint offers a balance between electrical performance and board real estate efficiency. Consider the 150 Ohm ESR value to ensure compatibility with the oscillator circuit's drive level requirements and loading capacitance calculations.

Part Context

This part belongs to the CFPX-104 series from IQD Frequency Products, a line of high-performance quartz crystals. The series is engineered for general-purpose timing applications where reliability and precise frequency control are essential. IQD leverages extensive manufacturing experience to provide components suitable for diverse electronic environments.

Replacement Considerations

Cross-reference compatible parts based on identical 8 MHz frequency, 10 pF load capacitance, and CFPX-104 package dimensions. Verify that substitute components meet the same ±10 ppm tolerance and -40°C to +85°C operating temperature range to maintain circuit integrity.
