Appliance parts terminology without the guesswork

A correct-looking part can still be electrically or mechanically wrong for the appliance.

TermMeaningCaution
OEMOriginal-equipment manufacturer part or manufacturer-authorised replacement.Still confirm exact model/part number and any supersession.
AftermarketThird-party replacement intended to perform a similar function.Quality, approvals, fit and warranty implications can vary.
Superseded partA newer part number replaces an older one in the manufacturer parts system.Use documented supersession—not visual similarity.
AssemblySeveral components sold as one service unit.A small failed sub-part may not be separately supplied.
Revision / suffixVariant identifier within a model/part family.Can change connector, firmware, rating or physical fit.
Universal partMarketed for broad compatibility.“Universal” does not remove electrical, mechanical or certification requirements.

How to confirm a part responsibly

  • Use the complete model number and any service/product code.
  • Prefer manufacturer parts diagrams or authorised parts databases.
  • Check documented superseded part numbers.
  • Match electrical ratings, connectors, dimensions and approvals—not just appearance.
  • For safety-critical parts, use manufacturer-approved service information.
Do not buy from the error code alone: An error code can describe a system fault without proving which part failed.
