Crystals Procurement Notes

Verify the exact package variant against the datasheet, as HC-49/US dimensions are standardized but lead configurations may vary slightly between manufacturers. Confirm RoHS status directly with the supplier or official documentation before integration. Ensure the load capacitance matches the circuit design requirements precisely to avoid frequency drift issues in final assembly.

Crystals Selection Notes

Select this component when a standard 25 MHz reference is required for cost-sensitive designs utilizing through-hole technology. The HC-49/US format offers widespread availability and ease of manual or automated placement. Consider thermal stability requirements carefully, as commercial grade crystals may exhibit frequency shifts outside specified ambient conditions compared to industrial variants.

Crystals Part Context

This part belongs to the broader family of fundamental quartz crystals manufactured by TXC Corporation. These components serve as essential timing references in digital electronics. The 9C series designation typically indicates specific manufacturing processes or tolerance grades within the company's portfolio, distinguishing it from higher-frequency oscillator modules or surface-mount crystal units.

Crystals Replacement Considerations

Substitutes must match the 25 MHz frequency, 20 pF load capacitance, and HC-49/US physical footprint. Verify that alternative suppliers provide comparable ESR values and frequency stability tolerances. Cross-reference pin compatibility and soldering profiles to ensure seamless integration into existing PCB layouts without redesign.
