Crystals Procurement Notes

Verify the specific suffix 'AAE' against official TXC documentation to confirm the exact load capacitance and tolerance specifications. Ensure the selected variant matches the required operating temperature range and package dimensions for the target PCB layout. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status before finalizing procurement orders.

Crystals Selection Notes

Select this component when a fundamental frequency crystal is required for space-constrained designs. The 12 pF load capacitance must align with the oscillator circuit's input capacitance requirements. Consider the ±30 ppm stability limit for applications sensitive to frequency drift over the specified industrial temperature range. Verify that the 60 Ohm ESR is compatible with the host oscillator's drive level constraints.

Crystals Part Context

This part belongs to the 7M series of quartz crystals from TXC Corporation, which are characterized by their small footprint and suitability for high-density surface-mount applications. The series provides various frequency options within a standardized package outline, allowing designers to maintain consistent board layouts while adjusting timing parameters for different microcontroller or communication peripheral requirements.

Crystals Replacement Considerations

The 7M-28.63636MAHE-T is documented as a parameter-equivalent substitute by the manufacturer. Verify that the alternative part maintains identical electrical characteristics, including frequency, load capacitance, and ESR, before implementation.
