Crystals Procurement Notes

Verify the specific suffix CAT against the official CTS datasheet to confirm the exact load capacitance and terminal configuration, as suffixes define critical electrical parameters. Ensure compatibility with the target circuit's load capacitance requirements. Check for obsolescence status, as this part may be discontinued or replaced by newer series variants. Confirm RoHS compliance documentation is available for regulatory adherence. Validate that the 4-SMD no-lead footprint matches the PCB design constraints.

Crystals Selection Notes

Select this component when a compact surface-mount crystal with high stability is required for 19.2 MHz applications. The 4-SMD no-lead form factor offers space efficiency compared to through-hole alternatives. Consider the 120 Ohm ESR and 8pF load capacitance to ensure proper oscillator circuit design. Evaluate thermal performance within the -20°C to +70°C range for the intended environment. Compare against other 402 series variants if different frequencies or tolerances are needed.

Crystals Part Context

This part belongs to the CTS 402 Series, which comprises miniature surface-mount crystals. The series is characterized by small footprints and leadless designs to facilitate high-density PCB mounting. These components are widely used in consumer electronics and industrial equipment requiring reliable timing sources. The 402 series typically offers various frequency options and packaging styles to meet diverse design requirements.

Crystals Replacement Considerations

Direct substitutes include 402F19211CAR and 402F19211CLR from CTS-Frequency Controls. Verify that alternative parts match the 19.2 MHz frequency, ±10ppm tolerance, and 8pF load capacitance. Ensure the replacement maintains the 4-SMD no-lead package dimensions for mechanical compatibility. Check for any changes in ESR or temperature stability specifications.
