Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact frequency, tolerance, and temperature grade specifications. Ensure compatibility with standard reflow soldering profiles as the component is MSL Level 1 rated. Cross-reference the part number with authorized distributors to obtain current technical documentation and avoid counterfeit components.

Crystals Selection Notes

Select this component when space optimization is critical alongside industrial temperature performance. The four-pad grounding design offers superior electromagnetic interference immunity compared to two-pad alternatives. Consider the low ESR specification for easier circuit matching and improved cold-start reliability. Validate that the 25 MHz frequency aligns with the target system's clock requirements.

Crystals Part Context

This part belongs to the SXT114 series of miniature crystals from Suntsu Electronics. The series utilizes a standardized naming convention where '114' denotes the series, '8' indicates the 1.6x1.2mm package, 'F' specifies ±10 ppm tolerance, 'E' denotes ±10 ppm stability, and '38' represents the -40 to +85°C temperature range. This systematic coding allows for precise configuration without constant datasheet consultation.

Crystals Replacement Considerations

Direct substitutes within the same series include SXT1148FE38-27.000M and SXT1148FE38-40.000M for different frequencies. Other Suntsu models sharing the 1.6x1.2mm form factor may be compatible if electrical parameters match. Verify pinout and loading capacitance requirements before substituting with generic equivalents.
