Procurement Notes

Verify the specific manufacturing status before procurement, as this part may be discontinued or subject to last-time buy restrictions. Confirm that the through-hole package dimensions match the target PCB footprint requirements. Ensure the operating temperature range meets the environmental specifications of the final application. Cross-reference the datasheet revision to confirm electrical parameters remain consistent with design intent.

Selection Notes

Select this component when a low-cost, stable timing source is required for systems operating at 640 kHz. Consider the ±0.3% frequency tolerance against the jitter requirements of the connected digital logic. Evaluate the thermal environment to ensure operation remains within the specified -20°C to +80°C range. Compare against crystal alternatives if higher precision or lower phase noise is necessary for the specific application.

Part Context

This component belongs to the ZTB series of ceramic resonators from ECS Inc., which are widely used in embedded systems. The series offers various frequency options tailored for common microcontroller clock speeds. These devices bridge the gap between expensive quartz crystals and less accurate RC oscillators, providing a balanced solution for mass-produced consumer electronics where moderate accuracy suffices.

Replacement Considerations

Check for direct pin-compatible substitutes within the same series, such as other frequencies in the ZTB line, if available. Verify equivalent ceramic resonators from other manufacturers offering identical 640 kHz specifications and through-hole packaging. Ensure any replacement maintains the same frequency stability and temperature range characteristics.
