Crystals Procurement Notes

Verify the exact manufacturer designation as listings may reference TXC Corporation or FTS interchangeably due to historical acquisitions or rebranding. Confirm the part status is obsolete if sourcing from primary distributors. Ensure the HC-49S package dimensions match your PCB footprint requirements. Cross-reference the 18 pF load capacitance with your circuit design specifications to guarantee accurate frequency operation. Check for RoHS compliance documentation if required for your manufacturing standards.

Crystals Selection Notes

Select this component when a stable 4.9152 MHz reference is required with moderate precision needs. The HC-49S package offers a balance between size and mechanical robustness for through-hole assembly. Consider the ±30 ppm tolerance against your system's frequency budget. Evaluate the 18 pF load capacitance requirement against your circuit's stray capacitance to avoid frequency deviation. Compare against other crystals in the 9B series if different frequencies or tolerances are needed.

Crystals Part Context

This crystal belongs to the 9B series of MHz crystals produced by FTS. The series includes various frequencies such as 4.096 MHz, 48.000 MHz, and 54.000 MHz, all sharing similar electrical characteristics and packaging. The 9B-4.9152MAAJ-B specifically targets applications requiring this unique frequency point. The series is known for its resistance-welded construction, which distinguishes it from soldered alternatives in terms of long-term reliability.

Crystals Replacement Considerations

Direct substitutes include other 4.9152 MHz crystals in the HC-49S package with matching 18 pF load capacitance and ±30 ppm tolerance. Verify that any replacement maintains the same resistance-welded construction method. Check if alternative manufacturers offer equivalent parts under different naming conventions. Ensure the replacement part is available if the original is marked obsolete.
