9C-16.000MAAJ-T

Crystals Overview

The TXC Corporation 9C-16.000MAAJ-T is a fundamental-mode quartz crystal designed for surface-mount applications in the HC-49/US package. It operates at a nominal frequency of 16 MHz with a load capacitance of 18 pF and an equivalent series resistance (ESR) of 30 Ohms. The component provides a frequency tolerance and stability of ±30 ppm across its operating temperature range of -20°C to +70°C. Physical dimensions are approximately 11.40 mm in length, 4.80 mm in width, and 4.10 mm in maximum height. It utilizes a base harmonic mode and is RoHS3 compliant.

• High mass production capability supports large-scale deployment.

Crystals Applications

• Microcontroller clock sources
• Communication interface timing
• General-purpose digital circuitry

Crystals Procurement Notes

This component is officially listed as obsolete and no longer manufactured by TXC Corporation. Verification of current availability should focus on authorized distributors or third-party stockholders rather than direct factory orders. Buyers must confirm the authenticity and storage history of existing inventory units due to the end-of-life status. Cross-referencing alternative part numbers from the same manufacturer is recommended to ensure long-term supply chain stability for ongoing projects.

Crystals Selection Notes

Engineers selecting this part should note its specific 18 pF load capacitance requirement, which must match the oscillator circuit design. The ±30 ppm frequency tolerance defines its suitability for standard timing applications where high precision is not critical. The limited operating temperature range of -20°C to +70°C restricts use in harsh environmental conditions. Due to its obsolete status, replacement strategies should prioritize functionally equivalent crystals with compatible package dimensions and electrical parameters.

Crystals Part Context

The 9C series represents TXC Corporation's line of fundamental-mode quartz crystals housed in the widely adopted HC-49/US form factor. This series is known for balancing performance with cost-effectiveness for consumer electronics. The 9C-16.000MAAJ-T specifically targets the common 16 MHz frequency point used in many legacy and modern microcontroller systems. Its design emphasizes reliability through established manufacturing processes, although it has reached its end-of-life phase.

Crystals Replacement Considerations

Available substitutes include other 16 MHz HC-49S/SMD crystals with similar 18 pF load capacitance and ±30 ppm tolerance. Specific equivalent part numbers are not confirmed in the provided source data; users should consult distributor cross-reference tools for verified alternatives.
