Crystals Procurement Notes

Verify current availability status as the part may be discontinued or limited. Confirm exact package dimensions and soldering profiles against the official datasheet before integration. Ensure compatibility with existing PCB footprint and reflow processes. Check for RoHS compliance documentation if required by specific regional regulations. Validate substitute parts only if officially recognized equivalents are available.

Crystals Selection Notes

Select this component when a precise 19.2 MHz reference with tight ±10 ppm tolerance is required. The 12 pF load capacitance must match the oscillator circuit design. Consider the 4-SMD form factor for space-constrained applications. Verify that the 120 Ohm ESR aligns with the host oscillator's drive level requirements. Ensure the -40°C to +85°C range meets environmental conditions.

Crystals Part Context

This crystal belongs to the CTS 402 series of surface-mount frequency control components. The series offers various frequencies and packages optimized for consumer and industrial electronics. The 402F1921XILT specifically targets applications needing stable timing in small footprints. It complements other crystals in the lineup with similar electrical characteristics but different frequencies or tolerances.

Crystals Replacement Considerations

Direct substitutes include 402F1921XILR and 402F1921XIKT from CTS-Frequency Controls. These alternatives share identical electrical specifications and package dimensions. Verify pinout and mounting compatibility before substitution. Parameter-equivalent options may exist but require careful validation of load capacitance and ESR values.
