Oscillators Procurement Notes

Verify the specific suffix codes against official datasheets to ensure correct frequency tolerance and temperature range specifications. Confirm RoHS compliance status and lead-free material declarations prior to ordering. Cross-reference the manufacturer part number with authorized distributor catalogs to avoid counterfeit components. Ensure packaging quantities match production requirements without relying on speculative stock levels.

Oscillators Selection Notes

Select this component when a stable 12 MHz reference is required in compact surface-mount designs. Consider the CMOS output compatibility with downstream logic families. Evaluate the -30°C to +85°C operating range against environmental constraints. Compare power consumption metrics if battery life is a critical design factor. Verify pinout compatibility with existing footprint layouts.

Oscillators Part Context

This model belongs to the MQF574T33 series of TCXOs from Mercury United Electronics. The series offers various frequency options while maintaining consistent physical dimensions and electrical characteristics. It serves as a precision timing solution for applications demanding higher stability than standard crystal oscillators but with lower cost than oven-controlled variants.

Oscillators Replacement Considerations

Direct substitutes include other MQF574T33 variants with different frequencies or temperature ranges, such as MQF574T33-11.0592-1.0/-40+85 or MQF574T33-24.5535-2.5/-30+85, provided frequency differences are acceptable. Ensure replacement parts maintain the same 4-SMD package and CMOS output type for mechanical and electrical compatibility.
