Crystals Procurement Notes

This component is officially classified as obsolete by the manufacturer and is no longer in active production. Procurement should focus on identifying verified replacement part numbers or alternative components that meet identical electrical specifications. Verify compatibility with existing PCB footprints and circuit designs before sourcing substitutes.

Crystals Selection Notes

Select this component only if the specific 25 MHz frequency, 10 pF load capacitance, and ±10 ppm stability align with the design requirements. Due to its obsolete status, engineers must prioritize cross-referencing pin-compatible alternatives or redesigning the timing circuit to accommodate available modern equivalents from the same or other manufacturers.

Crystals Part Context

The 7B series represents a line of high-accuracy quartz crystals from TXC Corporation. This specific model utilizes a standard SMD footprint common in many legacy electronic designs.
