Crystals Procurement Notes

Verify the specific suffix codes against the official TXC datasheet to confirm exact electrical parameters such as load capacitance and frequency tolerance. Ensure that the ordering quantity aligns with the manufacturer's standard factory pack quantities to avoid partial reel issues. Confirm compliance requirements including RoHS status and moisture sensitivity levels prior to procurement integration.

Crystals Selection Notes

Select this component when a 25 MHz reference with ±20 ppm stability is required within a 3.2 x 2.5 mm footprint. Consider the 18 pF load capacitance requirement for oscillator circuit design compatibility. Evaluate the -40°C to +85°C temperature range against environmental conditions. Compare ESR specifications with target oscillator IC capabilities to ensure proper startup and sustained oscillation.

Crystals Part Context

This part belongs to the TXC 7M series of ultra-small SMD crystals. The series is characterized by thin profiles and low series resistance, targeting space-constrained portable electronics. It complements other variants in the lineup that offer different frequencies, tolerances, or temperature ranges while maintaining consistent physical dimensions for standardized PCB footprints.

Crystals Replacement Considerations

Direct substitutes must match the 25 MHz frequency, 18 pF load capacitance, 3.2x2.5mm package, and ±20 ppm tolerance. Verify equivalent ESR and temperature range specifications. Cross-reference with other manufacturers offering pin-compatible SMD crystals with identical electrical performance metrics.
