Crystals Procurement Notes

Verify the specific suffix codes against the manufacturer's official datasheet to ensure correct frequency, tolerance, and packaging specifications. Confirm that the requested variant matches the required load capacitance and ESR values for your circuit design. Check current availability status as components may be subject to discontinuation or supply chain fluctuations. Ensure compliance with RoHS3 and REACH regulations if required by your manufacturing standards.

Crystals Selection Notes

Select this component when a 19.2 MHz reference with tight ±10 ppm stability is required in a small form factor. Consider the 18 pF load capacitance requirement for oscillator circuit compatibility. Evaluate the 120 Ohm ESR against the oscillator driver strength specifications. The -20°C to +70°C operating range suits general commercial applications but may require higher grade parts for industrial environments.

Crystals Part Context

This part belongs to the CTS 402 series of surface-mount crystals, which are widely used in portable and space-constrained electronic devices. The series offers various frequencies and package sizes to support diverse timing needs. The 402F19211CDT specifically targets applications requiring stable clock generation in compact designs, such as mobile phones, wearables, and IoT modules.

Crystals Replacement Considerations

Direct substitutes must match the 19.2 MHz frequency, ±10 ppm tolerance, 18 pF load capacitance, and 4-SMD (2x1.6mm) package. Verify ESR compatibility (approx. 120 Ohms) and operating temperature range (-20°C to +70°C). Cross-reference with other manufacturers' SMD crystal offerings ensuring identical pinout and electrical characteristics for drop-in replacement.
