Crystals Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging configuration when ordering. Confirm that the RoHS status aligns with project environmental requirements. Ensure the supplier provides valid traceability documentation for the manufacturing batch. Cross-reference the exact part number against the manufacturer's current lifecycle status to avoid obsolete stock issues during procurement.

Crystals Selection Notes

Select this component when a standard 25 MHz clock source is required for consumer electronics. The ±30 ppm stability suits general-purpose timing applications where high precision is not critical. The HC-49/S form factor allows for direct replacement in existing designs utilizing this footprint. Consider the -20°C to +70°C operating range against the target environment's thermal profile.

Crystals Part Context

This part belongs to the 9C series of crystals from TXC Corporation, designed for cost-effective mass production. The series targets high-volume consumer markets such as PCs and set-top boxes. The 9C line emphasizes standard pinouts and widely available frequencies to simplify supply chain management for OEM manufacturers.

Crystals Replacement Considerations

Direct substitutes include other manufacturers' HC-49/S 25 MHz crystals with matching 18 pF load capacitance and ±30 ppm tolerance. Verify equivalent series resistance and operating temperature ranges before substitution.
