Crystals Procurement Notes

Verify the current manufacturing status before procurement as this specific part number may be obsolete or discontinued. Confirm that the 12 pF load capacitance matches the host circuit design requirements. Ensure the ±30 ppm frequency tolerance meets the system's synchronization needs. Check for valid replacement part numbers if availability is restricted in your region.

Crystals Selection Notes

Select this component when a small form factor is required for SMD assembly. The 12 MHz frequency supports standard serial baud rates and basic clocking needs. Consider the 100 Ohm ESR value for oscillator circuit compatibility. The -20°C to +70°C range suits general consumer electronics rather than harsh industrial environments.

Crystals Part Context

This component belongs to the TXC 7B series of缝焊 (seam-welded) surface-mount crystals. The series targets miniaturized electronic devices requiring stable timing references. The 7B designation indicates a specific package size and performance tier within the manufacturer's portfolio for consumer-grade applications.

Crystals Replacement Considerations

Public confirmed substitute part numbers include 7V-12.000MAAE-T and 7M-12.000MAAE-T from TXC Corporation. Other similar alternatives include FA-238V 12.0000MB-W3 from EPSON.
