Crystals Procurement Notes

This component is officially listed as obsolete and discontinued by the manufacturer. Procurement should focus on verifying the authenticity of remaining stock from authorized distributors or third-party suppliers. Buyers must confirm the production date and storage conditions to ensure component reliability before integration into new designs.

Crystals Selection Notes

Engineers replacing this part should prioritize components with identical electrical parameters, specifically the 14.31818 MHz frequency, 12 pF load capacitance, and 40 Ohm ESR. The physical footprint must match the 4-SMD, No Lead package dimensions to maintain PCB compatibility. Verify that substitute parts meet the same frequency stability and temperature range requirements.

Crystals Part Context

The 7B-14.31818MAAE-T belongs to the TXC crystal oscillator family, utilizing quartz resonance technology for precise timing. As an obsolete product, it represents a legacy solution previously used in consumer electronics and industrial equipment requiring stable clock sources without integrated oscillator circuitry.

Crystals Replacement Considerations

Public confirmed substitute part numbers include 7M-14.31818MAAE-T. Engineers should verify that the substitute maintains the same package outline and electrical characteristics to ensure seamless replacement in existing hardware designs.
