Crystals Procurement Notes

Verify the specific suffix codes against official Meritek documentation to confirm exact electrical tolerances and temperature ranges. Ensure the ordering part number matches the required load capacitance and frequency stability specifications for the target application. Cross-reference datasheets to validate RoHS compliance status and packaging details before procurement.

Crystals Selection Notes

Select this component when a 27 MHz reference signal is required in a compact surface mount form factor. Consider the 40-ohm series resistance and 16 pF load capacitance requirements for circuit compatibility. Evaluate the -40°C to +85°C operating range against environmental conditions. Confirm that the HC-49SMD footprint aligns with the PCB layout constraints.

Crystals Part Context

This crystal unit belongs to Meritek's SMD crystal lineup, designed for general-purpose timing applications. It replaces through-hole variants by offering similar electrical characteristics in a reduced physical volume. The HC-49SMD package provides a balance between performance and board space efficiency for modern electronic devices.

Crystals Replacement Considerations

Direct substitutes include other manufacturers' HC-49SMD crystals with identical 27 MHz frequency, 16 pF load capacitance, and compatible series resistance. Verify pinout compatibility and thermal characteristics when cross-referencing alternative brands.
