Genuine or equivalent parts: how to choose for port equipment?

OEM parts guarantee fit but can take long to arrive; equivalents are cheaper and quicker but must be chosen carefully. Here is how TTT advises customers.

Genuine or equivalent parts: how to choose for port equipment?

When a machine is down waiting for parts, the question is: wait for genuine (OEM) or use an equivalent (aftermarket) part? There is no single answer.

When to use genuine parts

  • Safety-critical items: brakes, twistlocks, hoist ropes.
  • Equipment still under the manufacturer’s warranty.
  • Electronics and controllers that need the right software.

When equivalents make sense

  • Consumables: filters, gaskets, seals, belts, standard bearings.
  • Genuine stock is out or lead time is too long compared with downtime cost.
  • Reputable equivalent brands with traceable documents.

How to choose an equivalent

  1. Matching specifications and interchangeable dimensions.
  2. A cross-reference to the OEM part number.
  3. Certificates of origin/quality or full invoices.
  4. A clear warranty policy.
