Crystals Procurement Notes

Verify that the specific suffix ABNT corresponds to the 30 pF load capacitance variant, as other suffixes like ABJT indicate different capacitance values. Confirm RoHS compliance status and moisture sensitivity level requirements before finalizing procurement orders to ensure compatibility with assembly processes.

Crystals Selection Notes

Select this component when a 14.31818 MHz frequency with 30 pF load capacitance is required for surface-mount designs. Ensure the circuit design accommodates the specified ±30 ppm tolerance and the -10°C to +60°C operating temperature range. Compare against alternative suffixes if different capacitance or temperature ratings are needed.

Crystals Part Context

This part belongs to the HCM49 series of crystals from Citizen FineDevice. The series offers various frequency and capacitance options within the standardized HC-49/US SMD package. The ABNT suffix specifically denotes the 30 pF load capacitance configuration, distinguishing it from other variants in the same physical footprint family.

Crystals Replacement Considerations

Direct substitutes include parts with identical electrical parameters and package dimensions. Verify equivalent load capacitance and frequency tolerance when selecting alternatives from other manufacturers to maintain circuit timing integrity.
