Crystals Procurement Notes

This component is officially classified as obsolete and is no longer manufactured by TXC Corporation. Procurement should focus on verified substitute part numbers or alternative series components that meet the required electrical specifications. Verify availability through authorized distributors and confirm end-of-life status before finalizing design implementations to ensure supply chain continuity.

Crystals Selection Notes

Designers requiring a 48 MHz crystal should evaluate replacement options within the same manufacturer portfolio. Consider the 7V series or other available SMD crystals with matching 12 pF load capacitance and similar dimensional constraints. Ensure the selected substitute maintains compatibility with the target circuit's ESR requirements and operating temperature range while adhering to current manufacturing standards.
