Crystals Procurement Notes

Verify the specific suffix 'CJR' against the manufacturer's current datasheet to confirm packaging and material specifications. Check official distributor channels for availability status, as this part may be discontinued or subject to limited supply. Ensure the receiving facility handles the 4-SMD components according to MSL Level 1 guidelines to prevent moisture-related damage during storage and reflow soldering processes.

Crystals Selection Notes

Select this component when a 19.2 MHz fundamental frequency is required with ±10 ppm stability. The 9 pF load capacitance must match the oscillator circuit design. Consider the 120 Ohm ESR limit for driver strength requirements. The -20°C to +70°C operating range suits general industrial environments. Verify that the 2.00mm x 1.60mm footprint fits the PCB layout constraints.

Crystals Part Context

This crystal belongs to the CTS 402 Series, which utilizes a standard 2.0mm x 1.6mm seam-welded package. The series offers various frequencies from 16 MHz upwards, providing a consistent form factor for space-constrained surface-mount designs. The 402 series is widely used in consumer and industrial electronics requiring reliable fundamental mode timing.

Crystals Replacement Considerations

Direct substitutes include 402F19211CAR and 402F19211CLT from CTS-Frequency Controls. These alternatives share identical electrical parameters and mechanical dimensions. Verify package compatibility and ensure the replacement maintains the same load capacitance and ESR values for circuit integrity.
