Crystals Procurement Notes

Verify the manufacturer designation carefully, as this part number appears associated with both TXC Corporation and FTS in public databases. Confirm RoHS compliance status and exact package dimensions against the specific supplier's datasheet before finalizing procurement to ensure compatibility with your manufacturing requirements.

Crystals Selection Notes

Select this component when a standard 18.432 MHz reference is required for general-purpose digital logic or communication interfaces. Ensure the target application operates within the specified commercial temperature range and that the circuit design accommodates the 18 pF load capacitance for optimal frequency accuracy.

Crystals Part Context

This crystal belongs to the 7A series of surface-mount resonators, widely used in consumer electronics and industrial control applications. The 18.432 MHz frequency is a common choice for baud rate generation in serial communication protocols, offering a convenient divisor for various clock speeds.

Crystals Replacement Considerations

Public records indicate the TXC variant of this part number is obsolete. Verify direct pin-compatible substitutes from other manufacturers that match the 18.432 MHz frequency, 18 pF load capacitance, and ±30 ppm tolerance specifications.
