Telecom Procurement Notes

This component is officially classified as obsolete by the manufacturer and is no longer in active production. Availability is limited to existing stock or surplus channels. Engineers must verify end-of-life status before finalizing designs. Alternative solutions should be evaluated immediately to ensure long-term supply chain stability and project continuity.

Telecom Selection Notes

Designers should consider the obsolete status when selecting this part for new products. The integration of the switching regulator simplifies power architecture but requires careful thermal management. Verify that the 100V absolute maximum rating aligns with the target network environment. Check for pin-compatible alternatives if future production volume is required.
