Crystals Procurement Notes

Verify the specific suffix designation to ensure correct load capacitance matching, as variations exist within the IL3X family. Confirm RoHS compliance status prior to integration. Note that availability may be limited due to potential end-of-life status; validate current production status with authorized distributors before finalizing procurement plans.

Crystals Selection Notes

Select this component when a 7 pF load capacitance aligns with the host circuit's oscillator requirements. Compare against alternatives like the IL3X-HX5F6 if a 6 pF load is necessary. Ensure the 65 kOhm ESR is compatible with the microcontroller or RTC input impedance. Verify package dimensions fit the designated footprint on the printed circuit board.

Crystals Part Context

This part belongs to the ILSI IL3X series of surface-mount crystals. It shares the same physical form factor and base frequency with variants such as the IL3X-HX5F6 and IL3X2-HX5F7, differing primarily in load capacitance specifications. The series is widely used in consumer and industrial electronics requiring precise timekeeping.

Crystals Replacement Considerations

Public sources indicate the IL3X-HX5F7-32.768KHZ may be discontinued. Potential substitutes include the IL3X-HX5F6-32.768KHZ or IL3X2-HX5F9-32.768KHZ, though these feature different load capacitances (6 pF and 9 pF respectively). Direct replacement requires verification of circuit compatibility with the altered load capacitance values.
