Crystals Procurement Notes

This specific part number is officially listed as obsolete and no longer manufactured by TXC Corporation. Procurement must focus on identifying verified replacement components within the same product family or equivalent specifications from current production lines. Verify that substitute parts maintain identical package dimensions, electrical parameters, and mounting requirements to ensure seamless integration into existing designs without hardware modification.

Crystals Selection Notes

Designers should evaluate alternative models within the TXC 7A series that share the 5.0 mm x 3.2 mm footprint and 25 MHz frequency. Key selection criteria include matching the 20 pF load capacitance and ±30 ppm tolerance. Ensure the replacement maintains the glass-sealed technology if environmental robustness is critical. Confirm availability and lead times for the chosen substitute before finalizing the bill of materials.

Crystals Part Context

The 7A series represents TXC's line of high-reliability, glass-sealed surface-mount crystals. These components are engineered for applications requiring superior resistance to moisture and thermal stress compared to standard ceramic packages. The 7A-25.000MAAK-T specifically targets compact consumer electronics where size constraints and signal integrity are paramount.
