Obsolete material management hinges on "prevention first": mitigate risks through early warnings/redundant designs. In case of obsolescence, resolve supply issues rapidly via alternative component evaluation, inventory transfer, and supply chain collaboration. Long-term, diversify supply chains and advance technology to eliminate single-component dependence and enhance risk resistance.

Regularly engage core suppliers to monitor component lifecycles: active, upcoming EOL, EOL notice.
Monitor component end-of-life (EOL) status in real time via supplier portals, industry databases, or third-party platforms.
Substitute Part Screening: Filter by capacitance, tolerance, voltage rating; verify ESR, package fit, certifications.
Emergency Procurement: Pool internal stock, source last-time buys via distributor spots or supplier talks.
Quality: Alternative materials must pass reliability testing and small-batch trial production.
Compliance: Verify RoHS and other certifications for third-party procurement.
Cost: Pre-budget for EOL price hikes; lock prices via bulk buys.
