Crystals Procurement Notes

This component is officially listed as obsolete and no longer manufactured by TXC Corporation. Availability is restricted to existing stock or surplus channels. Verify end-of-life status and lead times with suppliers before procurement planning.

Crystals Selection Notes

Select this part only if the specific 31.5 MHz frequency, 18 pF load capacitance, and HC-49/US form factor are required. Due to its obsolete status, ensure that alternative sourcing options are viable and that the component meets all electrical specifications for the target application without modification.

Crystals Part Context

The 9B series represents a line of resistance welded crystal units from TXC Corporation. These components are designed for standard through-hole applications, offering reliable performance in various electronic systems requiring precise frequency generation.

Crystals Replacement Considerations

As the 9B-31.500MAAJ-B is obsolete, direct substitutes must match the 31.5 MHz frequency, 18 pF load capacitance, 80 Ohm ESR, and HC-49/US package. Consult manufacturer databases for cross-references or compatible alternatives.
