Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required load capacitance and frequency tolerance specifications. Confirm that the 4-SMD No Lead package aligns with your PCB layout constraints and reflow soldering profiles. Cross-reference the active status with official distributor channels to avoid obsolete stock.

Crystals Selection Notes

Select this component when space-constrained designs require a 31.25 MHz reference with ±20ppm accuracy. Ensure the circuit design accommodates the 12pF load capacitance requirement. Compare ESR values against oscillator input impedance limits to guarantee reliable startup conditions in low-power applications.

Crystals Part Context

This part belongs to the 7M series of seam sealing crystals from TXC Corporation. These units are characterized as extremely small SMD-type crystal resonators engineered for applications demanding high reliability and miniaturization. The series supports various frequencies while maintaining consistent physical dimensions and electrical performance standards across the product line.

Crystals Replacement Considerations

Direct substitutes must match the 31.25 MHz frequency, ±20ppm tolerance, 12pF load capacitance, and 4-SMD No Lead package dimensions. Verify equivalent ESR ratings and operating temperature ranges before substitution.
