Crystals Procurement Notes

Verify the specific model suffix against official manufacturer documentation to confirm frequency tolerance and package variations. Ensure compatibility with existing PCB footprint dimensions, specifically the 3.00mm x 8.00mm cylindrical form factor. Confirm that the 40 kOhm ESR aligns with the oscillator circuit requirements. Check for RoHS3 compliance status if environmental regulations are mandatory for the target assembly.

Crystals Selection Notes

Select this component when a standard 32.768 kHz reference with ±10 ppm accuracy is required for through-hole designs. The 12.5 pF load capacitance must match the oscillator circuit's capacitive requirements. Consider the 40 kOhm ESR limit for circuit stability. The radial cylindrical package dictates specific drilling and spacing constraints on the printed circuit board layout compared to surface-mount alternatives.

Crystals Part Context

This part belongs to the HKC crystal oscillator family, specifically designed for low-frequency timing applications. It serves as a fundamental resonator for generating stable clock signals in digital systems. The product line emphasizes standard industrial specifications for cost-effective timekeeping solutions in mass-produced electronic devices.

Crystals Replacement Considerations

Substitutes must maintain the 32.768 kHz frequency, 12.5 pF load capacitance, and 40 kOhm maximum ESR. Verify identical cylindrical radial package dimensions (3.00mm x 8.00mm) for mechanical fit. Ensure the replacement component supports the same -20°C to 70°C operating temperature range and fundamental mode operation.
