Crystals Procurement Notes

This component is officially classified as obsolete and no longer in active production by the manufacturer. Procurement should focus on verifying the authenticity of remaining stock from authorized distributors or secondary market suppliers. Buyers must confirm that inventory represents genuine units rather than refurbished items, as availability is limited and subject to depletion without restocking. Validate all incoming parts against original datasheet specifications before integration into designs.

Crystals Selection Notes

Engineers replacing this part must account for its discontinued status when finalizing long-term product designs. Selection criteria should prioritize components with identical electrical parameters, specifically the 24.576 MHz frequency, 20 pF load capacitance, and compatible package dimensions. Verify that alternative sources offer new old stock or qualified equivalents that meet the required thermal and stability specifications for the target application environment.

Crystals Part Context

The 9C series represents a line of standard quartz crystal resonators produced by TXC Corporation, widely utilized in general-purpose electronic devices requiring reliable frequency control. This specific model belongs to the HC-49/SMD variant family, bridging traditional through-hole performance with modern surface-mount convenience. The 9C designation indicates specific internal construction and electrode configurations optimized for the 24.576 MHz band within the broader portfolio of timing solutions.

Crystals Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include QT49S-24.000MBBK-T from QST. Designers should verify pin compatibility and electrical equivalence before substitution. No other direct replacements are explicitly documented in available public records.
