Crystals Procurement Notes

Verify that the specific order matches the E1SEA18-24.000M TR designation to ensure correct load capacitance and frequency tolerance. Confirm RoHS compliance status if required by project specifications. Check datasheet for storage temperature limits and handling precautions related to the SMD package type before assembly.

Crystals Selection Notes

Select this component when a 24 MHz surface mount crystal with 18 pF load capacitance is required. Ensure the application environment stays within the -20°C to +70°C operating range to maintain ±50 ppm stability. Consider the HC-49/UP Short footprint compatibility with PCB layout constraints.

Crystals Part Context

This part belongs to the Ecliptek E1S series of quartz crystal resonators. The series offers various frequencies and packages optimized for surface mount technology. The E1SEA18 variant specifically denotes the 18 pF load capacitance configuration within the HC-49/UP Short form factor.

Crystals Replacement Considerations

Direct substitutes must match the 24 MHz frequency, 18 pF load capacitance, and HC-49/UP Short package dimensions. Verify equivalent aging rates and stability specifications across the required temperature range before substitution.
