Crystals Procurement Notes

Verify the specific suffix 'IDR' against the manufacturer's current datasheet to confirm tape-and-reel packaging specifications and availability status. Ensure the selected variant matches the required load capacitance and ESR values for the target circuit design. Cross-reference the part number with official distributor catalogs to confirm current production status and lead times.

Crystals Selection Notes

Select this component when a 38.4 MHz fundamental frequency is required for digital logic or communication interfaces. The 18 pF load capacitance must match the oscillator circuit design parameters. Consider the 60 Ohm ESR value for drive level sensitivity. The 4-SMD package size is appropriate for space-constrained designs requiring reliable surface-mount technology integration.

Crystals Part Context

This part belongs to the 402 series of SMD crystals from CTS-Frequency Controls. The series provides various frequencies and package sizes optimized for consumer and industrial electronics. The 402 series typically utilizes standard AT-cut quartz elements for stable performance across the specified temperature range.

Crystals Replacement Considerations

Direct substitutes include other 38.4 MHz crystals with identical 18 pF load capacitance and compatible ESR values. Verify package dimensions and pin configuration compatibility before substitution. Alternative parts from different manufacturers may require impedance matching adjustments.
