Crystals Procurement Notes

Verify the specific suffix and manufacturer part number against official datasheets to confirm electrical parameters and package dimensions. Ensure compatibility with reflow soldering profiles and check for RoHS compliance status prior to integration into production designs.

Crystals Selection Notes

Select this component when a 27 MHz reference is required with moderate stability. Consider the 12 pF load capacitance requirement for circuit design matching. Evaluate thermal constraints against the specified -20°C to +70°C operational window.

Crystals Part Context

This part belongs to the 7M series of surface-mount crystals from TXC Corporation. It serves as a direct replacement for older through-hole or larger SMD variants where space savings are critical. The series offers standardized footprints for automated pick-and-place manufacturing.

Crystals Replacement Considerations

The 7S-27.000MAAE-T is listed as obsolete with the 7M-27.000MAAE-T identified as a similar substitute. Verify pinout and electrical equivalence before swapping.
