Crystals Procurement Notes

This component is officially listed as obsolete and no longer manufactured by the producer. Current availability is limited to existing stock or third-party distributors. Verification of authenticity and storage history is critical when sourcing from non-direct channels due to the end-of-life status. Buyers should confirm the specific revision level and packaging type before procurement to ensure compatibility with assembly processes.

Crystals Selection Notes

Select this component only if the 30 MHz frequency and ±30ppm stability meet circuit requirements. The 18pF load capacitance must match the oscillator circuit design. Consider the -20°C to 70°C operating range against environmental conditions. Due to its obsolete status, alternative sourcing strategies or redesigns may be necessary for long-term production viability.

Crystals Part Context

The 7B series represents a line of surface-mount crystals from TXC Corporation. This specific model belongs to the standard 7B family characterized by small footprint and reliable performance. It serves as a passive timing element in electronic assemblies requiring stable frequency references without active drive requirements.

Crystals Replacement Considerations

Public confirmed substitute part numbers include 7B-30.000MAAE-T and other variants within the 7B series that share identical electrical parameters and package dimensions. Verify pinout and mounting specifications when substituting.
