Lifecycle sourcing context
Use this lifecycle status page to review non-active electronic components before purchase approval, BOM maintenance, repair demand, or redesign planning. Buyers can screen NRND parts, last time buy components, EOL electronic parts, obsolete ICs, discontinued semiconductors, connectors, memory, and passive components from one focused catalog view.
A non-active lifecycle status does not always mean a component is impossible to source. It does mean procurement should check manufacturer notices, available quantity, lead time, traceability, approved vendor rules, and whether a replacement or cross-reference path is needed before production release.
For replacement research, open the Cross-reference Center from any lifecycle review workflow. For urgent buys, submit an RFQ with the manufacturer part number, target quantity, date code requirements, packaging needs, and any engineering approval constraints.
It usually means the part is NRND, last time buy, end-of-life, obsolete, or discontinued. Buyers should verify manufacturer notices, stock, replacement options, and internal approval rules before sourcing.
Yes. Submit an RFQ with the exact MPN, manufacturer, quantity, and quality requirements so the sourcing team can check availability, traceability, and suitable procurement channels.
Use this page to discover products by lifecycle status. Use the Cross-reference Center when you already have a source part and want to review replacement, equivalent, or alternative component candidates.
