• General-purpose digital logic synchronization

Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to ensure correct packaging and material specifications. Confirm that the selected variant matches the required load capacitance and ESR values for the target circuit design prior to finalizing procurement orders.

Selection Notes

Select this component when a 40 MHz fundamental frequency is required in a compact surface-mount footprint. Ensure the application circuit provides the specified 6 pF load capacitance to maintain the rated frequency accuracy. Verify compatibility with the PCB layout dimensions for the 4-SMD package.

Part Context

This part belongs to NDK's line of general-purpose crystal units intended for consumer electronics and industrial equipment. It serves as a primary timekeeping element within oscillator circuits, replacing through-hole variants where space constraints necessitate surface-mount technology solutions.

Replacement Considerations

Direct substitutes require matching 40 MHz frequency, 6 pF load capacitance, and similar physical dimensions. Consult official cross-reference lists for verified alternatives from NDK or other manufacturers offering identical electrical characteristics and pin configurations.
