Crystals Procurement Notes

Verify current availability status as supply may be limited or subject to discontinuation notices. Confirm that the specific ordering suffix matches the required tape and reel packaging format. Ensure the selected variant aligns with the specified HC-49/US footprint and thermal requirements for the target application environment.

Crystals Selection Notes

Select this component when a 7.3728 MHz reference is required for serial communication standards such as RS-232 or Ethernet. The 18 pF load capacitance must match the external circuit design to achieve the specified ±50 ppm tolerance. Consider the -20°C to +70°C operating range against environmental conditions to ensure frequency stability meets system requirements.

Crystals Part Context

This part belongs to Ecliptek's line of programmable and fixed-frequency crystal devices. The manufacturer specializes in providing quick-turn solutions for clock generation needs. The E1SBA series represents standard crystal resonators designed for cost-effective integration into consumer and industrial electronics requiring precise timing references.

Crystals Replacement Considerations

Direct substitutes include other 7.3728 MHz crystals with identical 18 pF load capacitance and HC-49/US form factor. Verify that alternative components meet the same ±50 ppm tolerance and 120 Ohm ESR specifications to maintain circuit performance without modification.
