Crystals Procurement Notes

Verify current availability status as the product lifecycle is listed as obsolete or limited supply. Confirm RoHS compliance details and specific packaging requirements such as reel or cut tape before ordering. Check for discontinuation notifications from TXC Corporation to ensure long-term project viability.

Crystals Selection Notes

Select this component when AEC-Q200 qualification is required for automotive applications. Ensure the circuit design accommodates the 10 pF load capacitance and 11.4 mm x 4.8 mm footprint. Verify that the ±30 ppm tolerance meets system timing accuracy requirements within the specified temperature range.

Crystals Part Context

This part belongs to the AT series of crystals from TXC Corporation, designed for surface-mount applications. It shares the HC-49/S form factor with other variants but differs in frequency and electrical specifications. The series targets robust timing solutions for environments requiring standardized mounting profiles.

Crystals Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete lifecycle status, direct cross-referencing requires consulting official manufacturer substitution guides or authorized distributor databases for equivalent AEC-Q200 qualified 18.432 MHz crystals.
