Crystals Procurement Notes

This component is officially listed as End-of-Life (EOL) and has been discontinued by the manufacturer. Procurement should focus on identifying valid substitute part numbers from the same product family or alternative manufacturers. Verify that any replacement maintains identical electrical parameters, such as frequency, load capacitance, and ESR, to ensure circuit compatibility. Check current availability status through authorized distributors before finalizing selection.

Crystals Selection Notes

Select this component only if the specific 5.00mm x 3.20mm footprint and 18pF load capacitance are required by the design. Due to its discontinued status, engineers must evaluate alternative packages or frequencies if supply chain continuity is critical. Ensure the application environment stays within the -20°C to +70°C operating range. Confirm that the target PCB layout supports the 4-SMD no-lead termination style for proper soldering and reliability.

Crystals Part Context

The 7B series represents TXC Corporation's line of general-purpose SMD crystals. This specific model belongs to a family known for balancing performance with cost-effectiveness in consumer electronics. The 7B designation indicates a standard size and performance tier within the broader quartz crystal portfolio, typically targeting high-volume applications where moderate stability suffices.

Crystals Replacement Considerations

Publicly confirmed similar substitutes include 7M-19.200MAAJ-T and 7V-19.200MAAJ-T from TXC Corporation. These alternatives share the same frequency and basic specifications but may differ in physical dimensions or manufacturing processes. Verify mechanical fit and electrical equivalence before substitution.
