Crystals Procurement Notes

Verify the specific ordering suffix and package variant against the official datasheet before procurement. Confirm that the required load capacitance matches the target circuit design parameters. Ensure the operating temperature range meets the environmental specifications of the end application. Check current availability status as supply levels may fluctuate due to production cycles.

Crystals Selection Notes

Select this component when a 18.432 MHz frequency is required with tight ±10 ppm stability. The 10 pF load capacitance must align with the oscillator circuit design. Consider the 3.2 mm x 2.5 mm size constraint for PCB real estate. Evaluate the -20°C to +70°C range against operational conditions. Compare ESR and power dissipation limits with driver capabilities.

Crystals Part Context

This part belongs to the 7M series of crystals from TXC Corporation. The series focuses on small-sized, high-reliability surface-mount components. These devices are engineered for mass production environments requiring consistent performance. The 7M series typically offers various frequency options within standardized package dimensions.

Crystals Replacement Considerations

Direct substitutes include other 18.432 MHz crystals with identical 10 pF load capacitance and ±10 ppm tolerance. Verify mechanical compatibility with the 3.2 mm x 2.5 mm footprint and 0.7 mm height limit. Ensure electrical parameters such as ESR and drive level match the original design requirements.
