Crystals Procurement Notes

Verify that the specific order matches the AH-32.768KDZY-T part number to ensure correct load capacitance and tolerance specifications. Confirm that the receiving facility accepts AEC-Q200 certified components if the application does not strictly require automotive-grade qualification. Check packaging details against project requirements, as this component is typically supplied in tape and reel formats. Ensure storage conditions comply with moisture sensitivity level 1 guidelines to maintain solderability prior to assembly.

Crystals Selection Notes

Select this component when a fundamental mode crystal is required for low-power, low-frequency timing applications. The ±20 ppm tolerance suits general-purpose real-time clocks where higher precision is unnecessary. The 7 pF load capacitance must match the oscillator circuit design parameters specified by the host microcontroller or timer IC. Consider the physical dimensions of the 3.2x1.5 mm package against available board space constraints during the layout phase.

Crystals Part Context

This crystal belongs to the AH series from TXC Corporation, which focuses on small-form-factor quartz resonators. The series is engineered to meet the increasing demand for miniaturized timing solutions in modern electronics. As a fundamental mode device, it offers lower power consumption compared to overtone crystals while providing stable oscillation for standard digital logic interfaces.

Crystals Replacement Considerations

The AH-32.768KDZB-T is documented as a similar replacement option from TXC Corporation. Other manufacturers may offer functionally equivalent parts, but verification of pin compatibility, electrical parameters, and mounting footprint is required before substitution.
