OCM (Original Component Manufacturer)
Definition
An OCM (Original Component Manufacturer) is the company that actually manufactures an individual component, such as a semiconductor, passive, or connector maker. It is distinct from the OEM, which builds the finished product, and from distributors, which resell the OCM's parts.
Why it matters
The OCM controls the part's lifecycle. It decides when a component goes NRND and then End of Life, issues the change and discontinuation notices, and grants franchise agreements to authorized distributors. Identifying the OCM is a practical first step in sourcing, because it points you to authorized supply, valid cross-references, and the source of obsolescence notices.
