Crystals Procurement Notes

Verify the specific suffix against official Murata documentation to confirm exact electrical tolerances and packaging specifications. Ensure compatibility with standard lead-free reflow soldering profiles. Confirm that the selected variant meets the required thermal stability and aging rate specifications for the target application environment.

Crystals Selection Notes

Select this component when a 38.4 MHz reference is required for industrial applications within the 2016 footprint. Consider the 6 pF load capacitance for PCB layout calculations, accounting for stray capacitance. Verify that the driving level remains below 300 μW to prevent frequency drift or long-term degradation during operation.

Crystals Part Context

This part belongs to the XRCGB series of thin-type crystal units designed for general-purpose microcontrollers. The series provides a balance of small physical dimensions and robust performance suitable for non-safety-critical industrial electronics. It serves as a common timing source for communication interfaces requiring precise frequency references.

Crystals Replacement Considerations

Direct substitutes include XRCGB38M400F1S1JR0 and XRCGB38M400F1S2JR0. These variants share the same frequency and package but may differ in load capacitance values or specific operating temperature ranges. Cross-reference datasheets to ensure electrical parameter alignment before substitution.
