Crystals Procurement Notes

Verify the specific suffix 'IJR' against manufacturer documentation to confirm exact load capacitance and tolerance specifications, as suffixes define critical electrical parameters. Ensure compatibility with existing PCB land patterns for the 4-SMD no-lead package. Confirm moisture sensitivity level requirements for reflow soldering profiles. Check for alternative lead times if standard availability is constrained.

Crystals Selection Notes

Select this component when a 38.4 MHz fundamental crystal with tight ±10ppm tolerance is required. The 9pF load capacitance must match the oscillator circuit design. Consider the 60 Ohm ESR for drive level limitations. The 4-SMD package size dictates board space constraints. Verify temperature range suitability for the intended operational environment.

Crystals Part Context

This part belongs to the CTS 402 series of surface-mount crystals. The series offers various frequencies and packages optimized for consumer and industrial electronics. The 402F3841XIJR specifically targets applications needing high stability in a small form factor. It complements other CTS frequency control products like resonators and oscillators.

Crystals Replacement Considerations

Direct substitutes include CTS part numbers with identical electrical parameters and package dimensions, such as 402F3841XIAR or 402F3841XIKR, provided the load capacitance matches the circuit design. Cross-reference datasheets to ensure equivalent ESR and frequency stability before substitution.
