Crystals Procurement Notes

This component is officially listed as discontinued by the manufacturer. Verification of availability should be conducted through authorized distributors who may hold remaining stock or offer alternative sourcing channels. Users must confirm the end-of-life status and ensure that any available units are genuine and stored according to specified environmental conditions prior to integration into new designs.

Crystals Selection Notes

Engineers selecting this part should consider its discontinuation status when planning long-term production runs. The HC-49S form factor requires specific footprint compatibility on printed circuit boards. Designers must verify that the 20 pF load capacitance matches their oscillator circuit requirements and that the ±50 ppm stability meets the system's timing accuracy constraints under the specified operating temperature range.

Crystals Part Context

The 9C-54.000MBBK-T belongs to the 9C series of quartz crystals manufactured by TXC Corporation. This series is characterized by surface-mount packaging options that maintain the dimensional benefits of traditional through-hole crystals while enabling automated assembly processes. The 54 MHz frequency is commonly utilized in digital logic and communication protocols requiring precise timing references.

Crystals Replacement Considerations

As this part is discontinued, direct substitutes from the same manufacturer family with identical electrical parameters and pinout compatibility should be evaluated. Cross-referencing with other HC-49S surface mount crystals offering similar frequency, load capacitance, and stability specifications is recommended to ensure functional equivalence in existing designs.
