Crystals Procurement Notes

Verify the specific suffix 'CDR' against the manufacturer's official datasheet to confirm the exact operating temperature range and packaging configuration. Cross-reference the part number with current distributor listings to ensure availability status, as supply conditions may vary. Confirm that the 18 pF load capacitance matches the target circuit design requirements before finalizing procurement decisions.

Crystals Selection Notes

Select this component when a 27.12 MHz reference signal is required within a -20°C to +70°C operational environment. Ensure the application circuit provides the specified 18 pF load capacitance to achieve the stated ±30 ppm frequency accuracy. Verify that the 100 Ohm ESR aligns with the oscillator circuit's drive level constraints and that the 4-SMD form factor fits the available PCB real estate.

Crystals Part Context

This part belongs to the CTS 402 Series of thin-film quartz crystals. The series offers various frequencies in small SMD packages. The 402F27133CDR specifically targets applications needing 27.12 MHz stability in consumer or industrial electronics where moderate temperature performance and compact size are prioritized over high-precision automotive or wide-temperature specifications.

Crystals Replacement Considerations

Direct substitutes include 402F27011CDR, 402F27012IDR, 402F27022IDR, and 402F27033CDT from CTS-Frequency Controls. These alternatives share similar package dimensions and series characteristics but may differ in frequency, tolerance, or temperature range. Verify electrical parameters match the original design requirements before substitution.
