Procurement Notes

Verify the exact frequency tolerance and load capacitance requirements against your circuit design specifications before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD package footprint matches your PCB layout constraints to guarantee proper soldering and mechanical stability during assembly processes.

Selection Notes

Select this component when a stable 93.3333 MHz reference is required for LVCMOS-compatible digital circuits. Consider the low-profile 4-SMD package for space-constrained designs. Evaluate the 1.8V operating voltage against available power supplies. Verify thermal performance within the specified operating temperature range for reliable long-term operation in target environments.

Part Context

This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronic. The series typically offers various frequency options within a consistent 4-SMD form factor. These components are designed for general-purpose timing applications where moderate accuracy and low power consumption are prioritized over high-stability requirements found in TCXO or OCXO variants.

Replacement Considerations

Direct substitutes include other 93.3333 MHz LVCMOS oscillators in 4-SMD packages with 1.8V operation. Verify pinout compatibility and electrical parameters such as current consumption and startup time. Cross-reference with similar Mercury models like 18QHTF21-93.333333-PD if minor frequency precision differences are acceptable.
