NLA (No Longer Available) in Spare Parts Data

NLA is distinct from “discontinued” (production has stopped, but existing stock may still be available) and “out of stock” (a temporary condition that will be replenished). NLA is permanent and source-level: the part is gone from the supply chain.

When NLA applies

What the catalog should show

For an NLA part with a successor: resolve to the successor via the supersession chain and show the replacement clearly. The customer should not have to discover on their own that the part they need is NLA.

For an NLA part without a successor: show “no longer available — no replacement available” rather than “out of stock” (which implies the part will return). If aftermarket equivalents exist, those can be shown as alternatives with appropriate confidence labeling.

Where Claro fits

Claro tracks NLA as a lifecycle status on the product identity record, distinct from discontinued and out-of-stock. When a part reaches NLA, Claro checks for supersession chains and cross-references to surface any available alternatives — with the evidence and confidence behind each.

FAQ

What does NLA mean in spare parts? +

NLA (no longer available) means a part cannot be sourced from the manufacturer or any known supply channel. It is the final stage of the lifecycle: the part has been discontinued, existing stock is exhausted, and no replenishment is possible from the original source.

How is NLA different from discontinued? +

Discontinued means the manufacturer has stopped production. NLA means the part is also no longer available from any channel — the manufacturer, distributors, or remaining inventory. A part can be discontinued but still available from remaining stock. NLA is the point at which remaining stock is also gone.
