Select this component when a low-voltage 1.8V operation is required for timing applications. The LVCMOS output is suitable for direct interfacing with digital logic families. Consider the ±50ppm stability for applications not requiring high-precision oscillation. The enable/disable feature allows for dynamic power saving in battery-operated devices. Verify thermal performance within the specified -40°C to +85°C range for your environment.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options. The 'OE' suffix typically denotes specific packaging or tape/reel configuration, though verification is needed. Mercury Electronics specializes in quartz crystals and oscillators, providing timing solutions for industrial and consumer markets.

Oscillators Replacement Considerations

Direct substitutes may include other 1.8V LVCMOS oscillators in 4-SMD packages from manufacturers like Epson, IDT, or SiTime. Ensure replacement parts match the 4.296 MHz frequency, ±50ppm stability, and physical dimensions. Verify pinout compatibility and enable/disable logic levels. Check if alternative brands offer similar thermal and electrical specifications.
