Crystals Procurement Notes

Verify that the specific order matches the E1SEA18-16.000M TR designation to ensure correct 16 MHz frequency and 18 pF load capacitance. Confirm compliance with RoHS directives if required by project specifications. Check datasheet limits for drive level and storage temperature ranges against application requirements. Ensure PCB footprint aligns with HC-49/UP Short dimensions for proper soldering.

Crystals Selection Notes

Select this component when a 16 MHz surface mount crystal with 18 pF load capacitance is required. Consider the HC-49/UP Short form factor for space-constrained designs compared to standard through-hole packages. Evaluate the ±30 ppm initial tolerance and ±5 ppm annual aging against system timing accuracy needs. Verify that the 50 Ohm maximum ESR fits within the oscillator circuit design constraints.

Crystals Part Context

This part belongs to the E1S series of quartz crystal resonators from Ecliptek. The series includes various frequencies and load capacitances, such as the E1SEA18-18.600M TR and E1SEA16-16.000M TR. These components share common packaging and electrical characteristics but differ in nominal frequency and specific load capacitance values defined by the model suffix.

Crystals Replacement Considerations

Direct substitutes must match the 16 MHz frequency, 18 pF load capacitance, and HC-49/UP Short SMD package. Cross-reference with other manufacturers offering similar surface mount crystals with comparable ESR and tolerance specifications. Ensure any replacement maintains the same mechanical height and pad configuration for board compatibility.
