Crystals Procurement Notes

Verify the specific suffix variant required, as the XX placeholder indicates variable load capacitance or tolerance options within the 402 series. Confirm current availability status directly with authorized distributors, as supply chain fluctuations may affect stock levels. Ensure the selected variant matches the target circuit's load capacitance requirements precisely to maintain frequency accuracy. Cross-reference the manufacturer datasheet for any recent product change notifications regarding pinout or material composition updates.

Crystals Selection Notes

Select this component when a 19.2 MHz reference is needed in a compact surface-mount form factor. The 8 pF load capacitance suits circuits designed with matching external capacitors to achieve resonance. Consider the ±15 ppm tolerance for applications requiring moderate frequency precision. Evaluate the 120 Ohm ESR against the oscillator circuit's drive level limitations to prevent over-driving the crystal. Ensure the operating temperature range aligns with the environmental conditions of the final assembly.

Crystals Part Context

This part belongs to the CTS 402 series of miniature crystals, designed for space-constrained electronic designs. The series provides various frequency codes and load capacitance options to accommodate different oscillator topologies. The 402F192XXCKT specifically addresses the demand for stable 19.2 MHz references in portable and industrial devices where small footprint and reliable performance are critical.

Crystals Replacement Considerations

Substitutes must match the 19.2 MHz frequency, 8 pF load capacitance, and 4-SMD no-lead package dimensions. Verify that alternative components offer comparable ESR and frequency stability specifications. Check for compatibility with existing PCB land patterns and reflow soldering profiles. Ensure the replacement maintains RoHS3 compliance if required by the design specification.
