Crystals Procurement Notes

This component is officially listed as obsolete and no longer manufactured by TXC Corporation. Procurement must rely on verified substitute part numbers or remaining stock from authorized distributors. Verify that any alternative components match the required electrical parameters and mechanical footprint before integration into production lines.

Crystals Selection Notes

Engineers should evaluate the 9C series characteristics, including its low ESR design which supports reliable oscillation across the specified temperature range. When selecting replacements, ensure the substitute maintains the 18 pF load capacitance and ±10 ppm stability to guarantee compatibility with existing MCU or SOC clock inputs without requiring circuit redesign.

Crystals Part Context

The 9C series represents TXC Corporation's line of high-accuracy quartz crystals designed for cost-effective mass production in consumer electronics. This specific model belongs to the HC-49/US form factor family, widely adopted in industrial and commercial applications due to its standardized dimensions and proven reliability in high-volume manufacturing environments.

Crystals Replacement Considerations

Available substitutes include similar components such as the ABL-50.000MHZ##. Verify that replacement parts match the 50 MHz frequency, 18 pF load capacitance, and HC-49/US package dimensions to ensure functional equivalence.
