Crystals Procurement Notes

Verify the specific suffix codes against the official datasheet to confirm exact electrical tolerances and temperature ranges. Ensure the ordering quantity matches the manufacturer's minimum packaging requirements. Confirm RoHS compliance status through the latest product documentation before integration into regulated assemblies.

Crystals Selection Notes

Select this component when a 25 MHz fundamental crystal with 20 pF load capacitance is required. Verify that the 40 Ohm series resistance aligns with the driving circuit capabilities. Ensure the operating temperature range meets the application environment specifications. Compare physical dimensions against the PCB footprint constraints during layout design.

Crystals Part Context

This part belongs to the 7B series of surface-mount crystals from TXC Corporation. The series offers various frequency options in standardized packages. The 7B25000019 specifically addresses the common 25 MHz requirement found in many embedded systems. It represents a standard solution for basic timing needs where high stability is not the primary constraint.

Crystals Replacement Considerations

Direct substitutes must match the 25 MHz frequency, 20 pF load capacitance, and 4SMD package. Check equivalent parts from other manufacturers for identical pinout and mechanical dimensions. Verify that alternative components meet the same series resistance and temperature performance criteria.
