Genuine or Equivalent: How to Choose Without Overpaying

The question “genuine or equivalent” has no universal answer. It depends on what is fitted to the machine, how expensive downtime is and whether you have time to wait. Here is how to decide without emotion — with numbers and criteria.

First, the terminology

In the market, “equivalent” means three quite different things, and they must not be confused:

• An equivalent of the same size from another manufacturer — a part in its own right, with its own characteristics.
• A compatible equivalent — a part designed specifically as a replacement for a particular component.
• A remanufactured original (reman) — factory-rebuilt with a warranty, at a price below new.

The first two carry different levels of risk. A remanufactured original is often closer to new in service life than a “compatible equivalent” is.

When a genuine part is not up for debate

There are situations where saving money works against you.

Situation	Why
Machine under warranty	Fitting a non-genuine part almost always voids the warranty
Safety-critical component	Brake valves, steering, load holding
Proportional hydraulics	A deviation in the characteristic changes the behaviour of the whole system
Complex component with settings	Compensators and servo valves — the setup often matters more than the hardware

When an equivalent is justified

• Consumables and wear parts — seals, filters, hoses.
• Simple components — check valves, adapters, fittings, basic directional valves.
• Older machines where the genuine part is out of production.
• Seasonal work, where downtime costs more than the risk.
• A second spare on hand — fit the equivalent and keep the genuine part in reserve.

How to check an equivalent before buying

Five questions worth asking a supplier. If you do not get clear answers, do not take the risk.

1. Who makes it? Not “China”, but the specific factory or brand.
2. Is there a datasheet or specification? With real parameters, not marketing language.
3. What are the tolerances on mounting dimensions? Especially for cartridge valves and cavities.
4. What warranty applies? And what exactly does it cover — the part itself or the consequences?
5. Has this equivalent been fitted to this type of machine before? Experience counts for more than promises.

The economics: an honest calculation

The price difference between a genuine part and an equivalent is usually 20–60%. But the decision cannot be based on the part price alone.

Work it out like this:

• Cost of downtime — what the machine earns per day.
• Lead time — a genuine part is often 8–20 weeks away, while an equivalent may be in stock.
• Service life — if the equivalent lasts half as long, the saving disappears.
• Cost of a second repair — labour, logistics, lost time.

If a machine sits idle while it earns a hypothetical 30,000 a day, two weeks of waiting for a genuine part already costs hundreds of thousands. Against that, the price difference on the part stops being the main argument.

Our position

We are an independent supplier and are not an authorised distributor for any of the brands. That means we are not obliged to sell you only genuine parts — and we will not pass an equivalent off as genuine.

How we work:

• We offer both options when both are available.
• We show the difference in price, lead time and service life.
• We do not substitute an equivalent for a genuine part without your agreement.
• If an equivalent looks doubtful, we say so plainly, even if it means losing the deal.

The bottom line

Genuine and equivalent are not “good” and “bad”; they are two different tools. You buy genuine when predictability matters. You buy an equivalent when lead time and budget matter, and the risk is understood and acceptable.

The right approach is not to choose “forever” but to decide for the specific job: which machine, which component, what downtime costs and how long you are prepared to wait.
