Crystals Procurement Notes

This component has been officially discontinued and is no longer in active manufacturing production. Verification of availability should focus on surplus stock or alternative sources rather than direct manufacturer orders. Buyers must confirm the specific revision status and ensure that any available units are genuine products from authorized channels before acquisition.

Crystals Selection Notes

Engineers replacing this part should consider the discontinuation status when designing new hardware. While the electrical parameters such as 13.56 MHz frequency and 18 pF load capacitance are common, the specific ESR value of 40 Ohms and the HC-49/US footprint require careful matching. Alternative components must be evaluated for thermal performance and mechanical compatibility to ensure seamless integration into existing circuit designs.

Crystals Part Context

The 9C series represents TXC Corporation's line of surface-mount quartz crystals. This specific model targets applications needing reliable frequency generation at 13.56 MHz. The HC-49/US package offers a balance between size and robustness for surface-mount technology. As a discontinued item, it remains relevant for maintenance and repair scenarios where original design specifications must be strictly maintained.

Crystals Replacement Considerations

Public confirmed substitute part numbers include ABL-13.560MHZ-B4Y-T from Abracon LLC and QT49S-13.560MAHJ-T from QST. These alternatives offer similar electrical characteristics and should be verified against the original schematic requirements before implementation.
