Procurement Notes

Verify the exact part number suffix against official Mercury Electronics documentation to ensure correct output type and voltage specifications. Confirm that the OE suffix aligns with the required enable pin configuration. Cross-reference the package outline drawing to verify compatibility with PCB footprint designs before finalizing procurement orders.

Selection Notes

Select this component when a 49.5933 MHz clock signal is required with LVCMOS levels. Ensure the system power rail matches the 1.8V specification. Consider the small 2.0x1.6mm footprint for space-constrained layouts. Verify thermal performance within the -40°C to 85°C operating range for the specific application environment.

Part Context

This model belongs to the 18QHTF21 series of standard oscillators from Mercury Electronics. The series typically offers various frequency options within a standardized 4-pin SMD package. These components are engineered for general-purpose timing applications where size and power consumption are critical factors.

Replacement Considerations

Direct substitutes must match the 49.5933 MHz frequency, LVCMOS output, 1.8V supply, and 4-SMD no-lead package. Check manufacturer datasheets for equivalent parts from other suppliers offering identical electrical parameters and mechanical dimensions.
