Crystals Procurement Notes

Verify the specific suffix IVR against official datasheets to confirm the exact load capacitance and packaging configuration, as variations exist within the 402W series. Ensure compatibility with the target circuit's load capacitance requirements before integration. Cross-reference manufacturer documentation for current lifecycle status and RoHS compliance details to meet regulatory standards.

Crystals Selection Notes

Select this component when a 38.4 MHz fundamental frequency is required with tight initial tolerance. The 7 pF load capacitance dictates specific PCB trace and IC pin configurations. Consider the 50 Ohm ESR for drive level limitations and the operating temperature range suitability for the intended environment compared to commercial grade alternatives.

Crystals Part Context

This part belongs to the 402W series of sub-miniature surface-mount crystals from CTS-Frequency Controls. The series utilizes hermetic ceramic packages to provide robust performance across industrial temperature ranges. These components are engineered for high-frequency applications requiring minimal size and reliable long-term frequency stability.

Crystals Replacement Considerations

Direct substitutes include the 402WF38412ITR, which shares identical electrical parameters but differs in packaging quantity or reel specifications. Verify that any alternative maintains the 7 pF load capacitance and 38.4 MHz frequency to ensure circuit compatibility without redesign.
