Procurement Notes

Verify the specific suffix 'DZY' corresponds to the required 7 pF load capacitance and 1.6x1.0 mm package dimensions during procurement. Confirm RoHS compliance status matches project requirements. Ensure the selected variant aligns with the specified -40°C to +85°C operating temperature range for the intended application environment.

Selection Notes

Select this component when a 32.768 kHz frequency is required for real-time counting or division purposes. The 7 pF load capacitance must match the oscillator circuit design specifications. Consider the 1.6x1.0 mm footprint for space-constrained PCB layouts. Verify that the ±20 ppm tolerance meets the system's timing accuracy requirements under the expected operating temperature conditions.

Part Context

This part belongs to the QT1C series of thin-film quartz crystals from QST. The series offers various load capacitances and package sizes. The KDZY suffix indicates specific electrical and mechanical parameters distinct from other variants like KBZY or KDZC. These components are commonly used as primary clocks for low-frequency digital logic interfaces.

Replacement Considerations

Direct substitutes include parts with identical 32.768 kHz frequency, 7 pF load capacitance, and 1.6x1.0 mm SMD footprint. Verify equivalent tolerance and temperature range specifications before substitution. Cross-reference manufacturer datasheets to ensure pin compatibility and mounting reliability.
