Procurement Notes
This component has reached its End-of-Life status and is discontinued by the manufacturer. Sourcing new units is not possible through official channels. Engineers must verify availability only in existing surplus stock markets. Procurement should focus on identifying verified second-source alternatives that match the original electrical and mechanical specifications to ensure long-term supply chain stability.
Selection Notes
Selection requires careful evaluation of the obsolete status. Designers must assess if the specific 30-position, 2-row, SMT bottom-entry form factor is critical. If replacement is necessary, prioritize connectors with identical pin counts, pitch, and mounting style. Verify that any substitute maintains the same current rating and voltage withstand capabilities to ensure system reliability without redesigning the footprint.
