Crystals Procurement Notes

Verify the specific suffix I163-001 against the manufacturer's official datasheet to confirm exact electrical parameters and packaging details. Ensure compatibility with existing PCB layout constraints regarding the 4-SMD no-lead package. Cross-reference the load capacitance requirement of 4pF with the target circuit design to maintain frequency accuracy. Confirm that the operating temperature range meets the environmental specifications of the end application.

Crystals Selection Notes

Select this component when a small form factor is required alongside precise frequency stability. The 40 Ohm ESR value should be compatible with the oscillator circuit's drive level limitations. Consider the 4pF load capacitance requirement to avoid frequency pulling issues in the final assembly. The wide temperature range makes it suitable for industrial or automotive contexts where thermal stability is critical.

Crystals Part Context

This part belongs to Siward's XTL501200 series of micro-crystals. The series is characterized by its miniature size and high-frequency performance. Similar parts in the series may vary in frequency, load capacitance, and package type, but share the same general SMD no-lead construction. This specific model targets applications needing 38.4 MHz timing in constrained spaces.

Crystals Replacement Considerations

Direct substitutes must match the 38.4 MHz frequency, 4pF load capacitance, and 40 Ohm ESR. Verify that alternative manufacturers offer the same 2.0x1.6mm package dimensions. Check for equivalent temperature ratings and frequency tolerances. Ensure the replacement part is RoHS compliant if required by the assembly process.
