Industrial and marine automation systems rely heavily on the performance and reliability of their spare parts. Whether it’s a PLC module, a PCB board, a sensor, a controller, or a circuit breaker, every single component plays a critical role in ensuring smooth operations. But with the increasing availability of counterfeit parts in global markets, businesses are facing new challenges.
Fake automation parts look similar from the outside, but inside they lack the engineering, material quality, and testing standards that original manufacturers provide. These counterfeits can lead to downtime, equipment failure, safety hazards, and huge financial losses.
This guide explains how to identify original vs. fake automation spare parts so you can protect your systems, your workforce, and your investment.
Why Counterfeit Automation Parts Are a Growing Problem
The demand for spare parts in industries like marine, oil & gas, manufacturing, and power generation has been increasing. Because original OEM parts are costlier and sometimes difficult to source, fake suppliers take advantage by offering “low-cost alternatives” that look identical.
But the risks are huge:
-
Reduced lifecycle of equipment
-
Poor performance and calibration errors
-
Unexpected shutdowns
-
Safety risks to operators
-
Loss of warranty
-
High long-term cost
For mission-critical environments, using fake parts is never worth the risk.
Key Differences Between Original and Fake Automation Parts
Counterfeit components can be very convincing, but a careful inspection often reveals major differences. Here are the most reliable indicators:
Packaging Quality and Labels:
Original manufacturers maintain strict standards for packaging.
Look for:
✔ High-quality printing on labels
✔ Clear logos, barcodes & serial numbers
✔ Proper sealing and protective wraps
✔ Detailed spec sheets inside the box
Fake parts often have:
✘ Blurry logos or misprinted text
✘ Wrong font styles or color variations
✘ Missing QR codes or mismatched labels
✘ Poor-quality packaging material
Serial Numbers and Verification Codes
OEM brands like Siemens, ABB, Honeywell, Yokogawa, Mitsubishi, and Schneider Electric use unique serial IDs for traceability.
To verify:
-
Check the serial on the official manufacturer website
-
Cross-check with your supplier’s invoice
-
Look for hologram stickers or secure QR codes
Fake parts either have no serial number or use a repeated/invalid one.
Build Quality and Material Finishing
Original parts go through strict QC testing. They feel sturdy and professionally built.
Original parts have:
✔ Smooth finishing
✔ Durable casing
✔ High-quality connectors
✔ Detailed engraving or laser marking
Fake parts generally show:
✘ Rough edges or uneven finishing
✘ Loose connectors
✘ Lightweight or cheap material
✘ Inconsistent color and texture
Performance and Technical Specification Mismatch
Often, fake components fail during testing because they cannot handle rated loads, voltage, or temperature.
Signs of fake parts:
✘ Overheating
✘ Delayed response time
✘ Incorrect readings
✘ Failure under continuous load
If a part claims to support certain specifications but fails during basic testing, it’s a red flag.
How to Authenticate Automation Spare Parts Properly
To be fully sure about the originality, follow these steps:
Buy Only from Trusted Suppliers
Choose suppliers who have:
✔ A verified business identity
✔ Strong customer reviews
✔ Transparent return & warranty policies
✔ Direct sourcing from OEM distributors
Platforms like Aeliya Marine Tech promise authenticated, tested, and genuine industrial automation parts — minimizing risks.
Request Manufacturer Certificates
These may include:
-
Certificate of Origin (COO)
-
Quality Inspection Report
-
Declaration of Conformity (CE / UL)
-
OEM Warranty Statement
Fake sellers usually cannot provide these documents.
Compare With an Existing Original Part
If you already have a genuine unit:
-
Compare size, weight, and design
-
Check ports, terminals, and engraving
-
Compare internal components if possible
Even the smallest difference can reveal a counterfeit.
Use OEM Diagnostic Tools
Some brands allow you to verify original parts through:
-
QR code scanning applications
-
Firmware compatibility tests
-
Internal chip ID verification
Fake components usually fail firmware or compatibility checks.
Common Red Flags When Buying Automation Parts
Keep an eye on these danger signs:
⚠️ Very low price compared to market
⚠️ No invoice, no warranty, no documents
⚠️ Seller avoiding questions about authenticity
⚠️ Incorrect model numbers or outdated versions
⚠️ Generic packaging instead of OEM
If something feels “too good to be true,” it usually is.
What Happens If You Use Fake Spare Parts?
Counterfeit spare parts may save money upfront, but they cause heavy losses later.
Equipment Damage
Poor-quality circuits or connectors can cause short circuits, burnouts, or sensor failures.
Unplanned Downtime
A single faulty module can shut down an entire production line or vessel operation.
Safety Hazards
Fake parts may not meet safety standards, putting operators at risk.
Warranty Void
OEMs do not support warranties if unauthorized parts are used.
Increased Maintenance Costs
Cheaper parts fail faster, leading to repeated replacements and higher long-term expenses.
Tips for Ensuring Long-Term Reliability
-
Maintain a log of all spare parts purchased
-
Work with certified suppliers
-
Train your team to identify counterfeit indicators
-
Keep OEM datasheets for comparison
-
Regularly test modules before installation
-
Store parts in proper environmental conditions
Preventing counterfeit parts is easier than fixing the damage caused by them.
Why Choosing Genuine Automation Spare Parts Matters
The performance of your automation system depends on the reliability of its components.
Genuine parts offer:
✔ Longer life
✔ Accurate performance
✔ System safety
✔ Lower maintenance cost
✔ Compatibility with OEM software
✔ Guaranteed support & warranty
Investing in original parts protects your machinery and ensures smooth industrial and marine operations.
