Procurement Notes

Verify that the specific part number matches the required frequency, package dimensions, and electrical specifications before ordering. Confirm compatibility with the target circuit's voltage levels and load requirements. Ensure that the supplier provides authentic components from authorized channels to guarantee performance reliability and adherence to the manufacturer's quality standards.

Selection Notes

Select this component when a 24 MHz clock source is required in a small form factor. Consider the ±50 ppm stability requirement against system timing tolerances. Verify that the 3.3V supply voltage aligns with the design power budget. Ensure the CMOS output interface is compatible with the receiving logic inputs of the target application.

Part Context

This oscillator belongs to the QTM325 series, which features a standardized 3.2mm x 2.5mm footprint. The series offers various frequencies and stability options. The MBE suffix typically denotes specific electrical characteristics such as voltage and output type. This model represents a common choice for general-purpose timing needs in consumer and industrial electronics.

Replacement Considerations

Direct substitutes must match the 24 MHz frequency, 3.2x2.5mm package, 3.3V operation, and CMOS output. Verify pinout compatibility and thermal characteristics. Cross-reference with other manufacturers offering equivalent specifications in the same package style to ensure functional interchangeability.
