Crystals Procurement Notes

This specific part number is listed as obsolete and is no longer actively manufactured by TXC Corporation. Procurement should focus on verified substitute components or alternative part numbers within the same series that maintain identical electrical specifications and physical dimensions. Verify current availability through authorized distributors before finalizing design implementations.

Crystals Selection Notes

Select this component only if the application requires a 25 MHz fundamental crystal with 12 pF load capacitance and ±30 ppm tolerance. Due to its obsolete status, engineers must evaluate replacement options carefully. Ensure the substitute part matches the 2.5x2.0 mm footprint and 80 Ohm ESR requirements to maintain circuit stability without redesigning the PCB layout.

Crystals Part Context

The 7S series represents TXC Corporation's line of SMD glass-sealed crystals. These components are engineered for high reliability in environmental performance and are commonly used in compact electronic devices. The 7S-25.000MAAE-T specifically utilizes a parallel resonant fundamental mode, distinguishing it from series resonant variants or oscillator modules within the broader product catalog.

Crystals Replacement Considerations

Public confirmed substitutes include 7M-25.000MAAE-T and 7S-25.000MAHE-T. Both alternatives offer similar electrical characteristics and form factors. Verify that the selected substitute maintains the 12 pF load capacitance and 2.5x2.0 mm package dimensions to ensure compatibility with existing designs.
