Oscillators Procurement Notes

Verify the specific frequency tolerance and stability requirements against your application needs before procurement. Confirm that the 1.8V supply voltage aligns with your system's power architecture. Ensure the 4-SMD package footprint matches your PCB layout constraints. Check for any specific handling instructions regarding electrostatic discharge during installation.

Oscillators Selection Notes

Select this component when a low-profile surface-mount oscillator is required for 47 MHz applications. Consider the LVCMOS output compatibility with your target logic family. Evaluate the power-down feature if battery life or thermal management is critical. Verify that the operating temperature range meets your environmental specifications.

Oscillators Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series typically offers various frequency options within a standardized small outline package. These components are designed to replace through-hole crystals with more stable and easier-to-integrate active oscillator solutions in modern electronics.

Oscillators Replacement Considerations

Direct substitutes must match the 47.0016 MHz frequency, LVCMOS output, 1.8V supply, and 4-SMD package. Verify pinout compatibility and electrical characteristics such as current consumption and startup time. Cross-reference with other manufacturers' 4-pin SMD oscillators offering identical form factors and performance specs.
