Procurement Notes

Verify the specific suffix codes against the manufacturer's official part numbering guide to ensure correct output type and tolerance specifications. Confirm that the required frequency stability and operating temperature range align with the target application environment before finalizing procurement orders.

Selection Notes

Select this component when a standard 40 MHz clock source is required for digital signal processing or communication interfaces. Ensure the host circuit supports CMOS input thresholds and verify that the available board space accommodates the 7.0 x 5.0 mm footprint. Consider thermal management requirements if multiple oscillators are placed in close proximity.

Part Context

This oscillator belongs to the OC series of surface-mount crystal oscillators manufactured by Taitien. The series is characterized by its use of ceramic packages and robust performance in consumer electronics and telecommunications. It serves as a fundamental timing reference for microcontrollers and data transmission modules within larger electronic assemblies.

Replacement Considerations

Direct substitutes include other 40 MHz CMOS oscillators with identical 7.0 x 5.0 mm footprints and 3.3 V operation. Verify pin compatibility and electrical parameters such as phase jitter and load capacitance before swapping components.
