Procurement Notes

Verify the specific package dimensions and electrical parameters against the official NDK datasheet prior to integration. Confirm that the 8 pF load capacitance matches the target circuit design requirements. Ensure compliance with RoHS3 regulations if required by the end product specifications. Cross-reference the manufacturer part number CS14877-55.2M to avoid substitution errors during procurement.

Selection Notes

Select this component when a 55.2 MHz clock source with ±10 ppm stability is required in a compact 1.6x1.2 mm footprint. The 50 Ohm ESR and 8 pF load capacitance must align with the oscillator circuit design. Consider the -40°C to +85°C operating temperature range for environmental suitability. This part is appropriate for applications prioritizing size reduction without compromising frequency accuracy.

Part Context

This crystal belongs to the NX1612SA series from NDK, designed for high-density surface mount applications. The series offers various frequency options within a standardized small outline package. The CS14877-55.2M specifically addresses the need for stable timing in modern portable and industrial devices where board space is limited. It represents a standard solution for fundamental mode quartz resonators in the SMD category.

Replacement Considerations

Direct substitutes include other 55.2 MHz crystals with identical 8 pF load capacitance, ±10 ppm tolerance, and 1.6x1.2 mm package dimensions. Verify ESR compatibility, as values may vary between manufacturers. Ensure the replacement part supports the same operating temperature range and mounting style. Consult the official NDK documentation for approved alternative part numbers within the same series.
