Crystals Procurement Notes

Verify the specific suffix 'J' against the manufacturer's current datasheet to confirm packaging and availability status, as suffixes may indicate variations in reel quantity or handling. Ensure the design-in process accounts for the specified load capacitance of 9pF to maintain frequency accuracy within the stated tolerance limits during final product integration.

Crystals Selection Notes

Select this component when a 19.2 MHz fundamental crystal is required for space-constrained designs utilizing the 2.00mm x 1.60mm footprint. Consider the ±10ppm initial tolerance and ±15ppm total stability requirements relative to system timing budgets. Evaluate the -20°C to +70°C operating range against the intended environmental conditions of the end application.

Crystals Part Context

This part belongs to the CTS 402 Series, a line of general-purpose MHz crystals. The series offers various frequencies and package options tailored for consumer electronics and industrial control systems. The 402F19211CJT specifically addresses the common need for precise timing in digital systems requiring a 19.2 MHz reference clock.

Crystals Replacement Considerations

Direct substitutes within the same series include variants with different load capacitances or tolerances, such as 402F19211CAR or 402F19211CLR.
