Crystals Procurement Notes

Verify the current lifecycle status as this specific part number may be obsolete or discontinued. Confirm availability through authorized distributors or check for direct manufacturer updates regarding production status. Ensure that any substitute components maintain identical electrical parameters and physical dimensions to guarantee compatibility with existing circuit designs and PCB layouts.

Crystals Selection Notes

Select this component for applications requiring a compact 5.0 x 3.2 mm footprint. It is suitable for consumer electronics where space constraints are critical. The ±30 ppm stability meets standard requirements for general-purpose timing. Consider alternative models if higher precision or extended industrial temperature ranges are necessary for the specific application environment.

Crystals Part Context

This crystal belongs to the TXC 7B series, which specializes in small-volume surface-mount units. The series is engineered for high-frequency pullability and low ESR. These characteristics make the 7B series particularly effective for minimizing electromagnetic interference in dense electronic assemblies while maintaining reliable oscillation performance.

Crystals Replacement Considerations

Public confirmed substitutes include the 7M-27.000MAAJ-T and the 9C-27.000MAAJ-T. Verify package compatibility when switching between these options.
