Crystals Procurement Notes

Verify that the specific part number matches the required frequency, tolerance, and package dimensions. Confirm that the operating temperature range meets the environmental requirements of the target application. Ensure compatibility with the intended load capacitance and drive level specifications before integration.

Crystals Selection Notes

Select this component when a fundamental mode crystal with a 16 MHz nominal frequency is required. Consider the ±30 ppm tolerance and ±100 ppm stability limits against system timing accuracy needs. Verify that the 40 Ohm ESR and 20 pF load capacitance align with the oscillator circuit design parameters.

Crystals Part Context

This component belongs to the HC-49/USX series of quartz crystals from ECS Inc. International. These standard through-hole packages are widely used in general-purpose electronic circuits requiring stable frequency references. The series offers various frequency options and tolerance levels to suit different digital and analog applications.

Crystals Replacement Considerations

Substitute only with components explicitly confirmed as electrically equivalent by the manufacturer or authorized distributors. Verify identical frequency, tolerance, stability, load capacitance, ESR, and physical dimensions. Do not assume interchangeability based on package similarity alone.
