Crystals Procurement Notes

This component is officially discontinued and no longer manufactured by TXC Corporation. Procurement must focus on identifying verified substitute parts or alternative manufacturers offering equivalent electrical specifications. Verify that replacement components match the required 12 MHz frequency, 16 pF load capacitance, and 40 Ohm ESR to ensure circuit compatibility. Check RoHS compliance status of substitutes against project requirements.

Crystals Selection Notes

Selection should prioritize direct replacements matching the 5x3.2mm footprint and 12MHz fundamental frequency. Ensure the substitute maintains the ±10 ppm stability and -20°C to +70°C operating range. Verify pinout and soldering pad dimensions to prevent mechanical interference. Evaluate frequency tolerance requirements carefully, as tighter tolerances may require different series components.

Crystals Part Context

The 7B12000013 belongs to the TXC 7B series of surface-mount crystals. This series is characterized by its compact 5x3.2mm package size, suitable for space-constrained designs. The 7B series typically offers standard frequency stability options for general electronic applications requiring reliable timing references.

Crystals Replacement Considerations

Available substitutes include similar crystals from other manufacturers. Verify exact parameter matching for frequency, load capacitance, and physical dimensions before implementation.
