Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required load capacitance and tolerance specifications. Confirm that the bulk packaging format aligns with automated assembly or manual placement processes. Check for any recent updates to the RoHS compliance status or material declarations prior to final procurement approval.

Selection Notes

Select this component when a standard 16 MHz reference is required for general-purpose digital logic or microcontroller systems. Ensure the circuit design accommodates the specified load capacitance of 20 pF to maintain accurate frequency output. Consider the HC-49/U package dimensions for PCB layout constraints and verify that the operating temperature range meets the environmental conditions of the end application.

Part Context

This crystal belongs to IQD's standard fundamental mode lineup, widely used in cost-sensitive consumer and industrial devices. The HC-49/U form factor is a legacy but reliable package type, offering good availability and established design-in history across various electronic product categories requiring stable clock signals.

Replacement Considerations

Cross-reference with other manufacturers' HC-49/U 16 MHz crystals with 20 pF load capacitance. Verify equivalent series resistance and frequency stability ratings before substitution to ensure circuit performance remains within acceptable limits.
