Procurement Notes

Verify the specific suffix MEEY-T against the manufacturer's current datasheet to confirm pinout and loading capacitance specifications. Ensure the ordering part number matches the required frequency tolerance and package type exactly. Cross-reference the revision history for any updates to electrical characteristics or recommended soldering profiles before finalizing procurement.

Selection Notes

Select this component when a 26MHz reference is required in a minimal footprint form factor. Consider the 7pF load capacitance compatibility with the host circuit's input capacitance. Evaluate the ±10ppm stability requirement against system jitter budgets. Confirm that the 1.6x1.2mm package fits within the available board area constraints.

Part Context

This oscillator belongs to QST's line of miniature crystal units, targeting modern electronics where size reduction is critical. It serves as a replacement for larger through-hole or standard SMD crystals in applications demanding stable clock generation without significant board space consumption.

Replacement Considerations

Direct substitutes must match the 26.000MHz frequency, 1.6x1.2mm package, and 7pF load capacitance. Verify equivalent stability ratings from other manufacturers offering similar footprints. Ensure interface compatibility and thermal characteristics align with the original design specifications.
