Crystals Procurement Notes

Verify the specific datasheet version from Suntsu Electronics to confirm exact mechanical dimensions and soldering profiles. Ensure compatibility with reflow soldering processes defined in the manufacturer's guidelines. Cross-reference the part number suffix to confirm the 25 MHz frequency variant. Check for RoHS compliance status if required by project specifications. Confirm availability through authorized distributors as stock levels fluctuate.

Crystals Selection Notes

Select this component when a 25 MHz reference is required for space-constrained designs. The 18 pF load capacitance must match the oscillator circuit requirements. Consider the ±20 ppm stability for applications not requiring high precision. The 40 Ohm ESR should be compatible with the driving circuit's impedance. Evaluate the -20°C to +70°C range against environmental conditions.

Crystals Part Context

This crystal belongs to the SXT32418 series from Suntsu Electronics, which offers various frequencies in a standardized 4-SMD no-lead package. The series provides options for different load capacitances and stability grades. Similar parts include variants with different frequency codes such as 24.000 MHz or 48.000 MHz. The DD27 suffix typically indicates specific packaging or tape-and-reel configurations within the product line.

Crystals Replacement Considerations

Direct substitutes may include other 25 MHz crystals with identical 18 pF load capacitance and 4-SMD no-lead footprint. Verify that alternative components meet the same ±20 ppm stability and 40 Ohm ESR specifications. Ensure the replacement part supports the same operating temperature range. Check mechanical compatibility with existing PCB land patterns.
