Crystals Procurement Notes

This component is officially obsolete and no longer manufactured by TXC Corporation. Procurement must focus on identifying verified parametric equivalents or authorized substitute part numbers from other manufacturers. Direct sourcing from the original manufacturer is not possible due to discontinuation status.

Crystals Selection Notes

Designers should verify that alternative components match the critical parameters of 18.432 MHz frequency, 12 pF load capacitance, and ±30 ppm stability. Ensure the replacement package matches the 2-SMD footprint and that the operating temperature range meets the specific application requirements of -20°C to +70°C.

Crystals Part Context

The 7A series represents TXC Corporation's line of high-accuracy surface-mount crystals. This specific model belongs to the broader category of MHz crystals used for stable clock generation in electronic systems. The 7A designation indicates a specific package style and performance tier within the manufacturer's historical product portfolio.

Crystals Replacement Considerations

Public confirmed substitutes include 435F18425CET from CTS-Frequency Controls. Designers should evaluate these alternatives for pin compatibility and electrical parameter alignment.
