Crystals Procurement Notes

Verify that the ordered part number matches DF18CC1-6.144MHZ-T exactly, including the suffix indicating tape and reel packaging. Confirm manufacturer origin is MMD Monitor/Quartztek. Ensure compliance with RoHS3 standards and check for any specific handling requirements related to the surface mount package during assembly processes.

Crystals Selection Notes

Select this component when a 6.144 MHz fundamental frequency is required with strict ±15ppm tolerance. The 18pF load capacitance must match the circuit design requirements. Consider the 90 Ohm ESR value for drive level sensitivity. The wide temperature range supports industrial applications requiring reliability between -40°C and 85°C.

Crystals Part Context

This crystal belongs to the D Series from MMD, designed for general-purpose timing applications. It utilizes a quartz resonator element housed in a standardized SMD package compatible with automated pick-and-place equipment. The product line emphasizes consistency in electrical parameters and mechanical dimensions for board layout standardization.

Crystals Replacement Considerations

Ecliptek part E1SJA18-16.9344M TR is listed as a similar substitute, though it differs in frequency. Verify exact parameter matching for frequency, load capacitance, and ESR before substituting other manufacturers' components.
