Crystals Procurement Notes

Verify the specific manufacturer datasheet to confirm the exact ESR value, as some sources cite 90 kOhms while others indicate variations around 65-70 kOhms for similar series variants. Ensure the load capacitance requirement matches the circuit design. Confirm RoHS compliance status directly with the supplier documentation before finalizing procurement orders.

Crystals Selection Notes

Select this component when a standard 32.768 kHz reference is required for timekeeping functions. The 12.5 pF load capacitance must align with the oscillator circuit's input capacitance. The 3.2 x 1.5 mm footprint is appropriate for space-constrained PCB layouts. Consider the ±20 ppm tolerance sufficient for general RTC applications where high precision is not critical.

Crystals Part Context

This part belongs to the IL3X series of thin-profile quartz crystals from ILSI. These components are engineered specifically for real-time clock applications in digital watches and portable gadgets. The series emphasizes miniaturization and low current draw, making them suitable for modern handheld devices requiring reliable timebase generation.

Crystals Replacement Considerations

Direct substitutes include other 32.768 kHz SMD crystals with identical 3.2 x 1.5 mm footprints and 12.5 pF load capacitance. Verify that alternative parts maintain comparable ESR specifications to ensure oscillator startup reliability. Cross-reference pin configurations and mounting styles to guarantee mechanical compatibility.
