Crystals 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 HC-49/U package dimensions match the target PCB footprint. Check for any recent updates regarding material composition or RoHS compliance status before finalizing procurement orders.

Crystals Selection Notes

Select this component when a fundamental frequency of 18.432 MHz is required with moderate stability. Ensure the application circuit can support the specified 20 pF load capacitance. Verify that the drive level does not exceed 1 mW to prevent frequency drift or damage. Consider thermal environment constraints relative to the standard operating temperature range.

Crystals Part Context

This part belongs to YIC's line of general-purpose quartz crystal units. It is designed for standard digital timing applications requiring stable frequency references. The HC-49/U package is widely used in consumer electronics and industrial control systems for its reliability and ease of automated assembly.

Crystals Replacement Considerations

Direct substitutes must match the 18.432 MHz frequency, 20 pF load capacitance, and HC-49/U package. Verify equivalent frequency tolerance and stability ratings from alternative manufacturers.
