Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure compatibility with required voltage levels and output types. Confirm that the package style matches the target PCB footprint requirements. Check for any recent updates to the datasheet regarding environmental compliance or pin configuration changes before finalizing procurement.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a specific 75.075 MHz frequency. Ensure the application supports LVCMOS logic levels and can accommodate the small 2.0x1.6 mm footprint. Consider the standby feature if power efficiency during idle states is a critical design parameter for the target system.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which focuses on miniature oscillators. The series typically offers various frequencies and voltage options within a standardized small outline package. It is positioned as a solution for space-constrained electronic designs requiring reliable clock signals.

Replacement Considerations

Direct substitutes may include other 1.8V LVCMOS oscillators at 75.075 MHz in a 4-SMD no-lead package. Verify electrical parameters and pinout compatibility before substitution.
