Allocation
Definition
Allocation is a supply condition in which demand for a component exceeds the manufacturer's ability to supply it, so the manufacturer rations available stock across its customers. During allocation, lead times extend, prices rise, and orders may be only partially filled.
Why it matters
Allocation differs from obsolescence: the part is still made, but there is not enough of it right now. It is usually temporary, though it can persist for many months during broad shortages. Sourcing through allocation means looking beyond authorized distributors, whose stock is the first to run dry, to the broker and surplus channels where scattered inventory remains. Qualifying a cross-reference or second source is a strong defense.

- Cross-Reference (Alternate Part): a way around a single allocated part.

Frequently Asked Questions
What does allocation mean for electronic components?+
Allocation is a condition where demand for a part exceeds the manufacturer's supply, so the manufacturer rations available stock across customers. Lead times stretch, prices rise, and buyers may not get their full order. Unlike obsolescence, allocation is usually temporary, but it can last many months.
How do I source a part that is on allocation?+
Options include buying available stock through brokers and surplus dealers, qualifying a cross-reference or second source, and placing orders early to hold a place in the queue. Broad supplier coverage helps, because inventory during allocation is scattered across many channels rather than sitting with authorized distributors.
