Crystals Procurement Notes

Verify the specific ESR value against circuit requirements, as datasheets may list 50 Ohms or 90 Ohms depending on the exact revision or testing conditions. Confirm that the 18 pF load capacitance matches the host oscillator's design specifications to ensure accurate frequency performance. Check for RoHS compliance documentation if environmental regulations apply to the final assembly. Ensure the surface-mount footprint aligns with the HC-49/US dimensions provided in the mechanical drawings.

Crystals Selection Notes

Select this component when a 13 MHz fundamental frequency is required for surface-mount designs. The 18 pF load capacitance must match the system's capacitive load to maintain the specified ±15 ppm tolerance. Consider the ±30 ppm stability requirement against the application's timing precision needs. The HC-49/US package offers a balance between size and robustness for general-purpose timing applications.

Crystals Part Context

This part belongs to the MMD D Series, which provides a wide range of surface-mount crystals. The series supports frequencies from 3.2 MHz to 80 MHz with various load capacitances and stability options. MMD, supported by Abracon, focuses on flexible timing solutions for the frequency control market. The DF18CC1 variant specifically denotes the HC-49/US SMD format within this lineup.

Crystals Replacement Considerations

Direct substitutes include other 13 MHz HC-49/US SMD crystals with matching 18 pF load capacitance and similar ESR values. Verify that alternative parts meet the same ±15 ppm tolerance and ±30 ppm stability specifications. Ensure the replacement component supports the required operating temperature range of -40°C to +85°C. Cross-reference pinout and mechanical dimensions to guarantee board compatibility.
