Maximum transparency
We show you, with meaningful assessments, how operating conditions and temperature affect the reliability of your product.
Reliability Analysis
How reliable is your electronic product?
With a comprehensive reliability analysis, you create the foundation for durable, reliable electronic products. In the TQ-Product-Compliance-Center, we assess the reliability of your assemblies and systems according to recognized standards – from the initial consultation through to MTBF calculation at component level. This allows you to identify risks early, optimize your design in a targeted way, and create robust evidence for approval procedures.
The most important questions at a glance
What is reliability analysis?
A reliability analysis assesses how likely it is that an electronic system or assembly will operate without failure over a defined period of time. A key metric is often the MTBF value (Mean Time Between Failures) – the average operating time between two failures.
What does MTBF stand for?
MTBF (Mean Time Between Failures) is a statistical value that describes the average operating time of systems and assemblies between two failures. It applies during the product lifespan without taking early-life or wear-out failures into account, and it refers to all products in the field.
What is the purpose of calculating MTBF?
A robust reliability analysis gives you a clear advantage at several stages in the product lifecycle:
- Spare parts management:
Plan inventory levels and replacement cycles specifically based on realistic failure probabilities. - Warranty & cost control:
MTBF values help calculate potential warranty claims at an early stage. - Approval & safety:
A robust MTBF value is often crucial for safety-related approvals, for example in the rail industry.
Reality check:
If desired, we compare calculated values with field data and thus validate your reliability analysis.
How reliability analysis works at TQ-PCC
Whether a complete MTBF analysis or independent consulting — you decide the scope you need.
We will guide you through the entire process if desired:
- Initial consultation: Together, we define a suitable calculation standard.
- MTBF calculation: We calculate reliability at the component level.
- Interpretation of the results: You receive a clear, well-supported assessment.
- Recommendations for action: Upon request, we can show specific optimization measures.

FAQs on Reliability Analysis
Which calculation standard should I choose for my reliability analysis?
This depends on your industry, the relevant approval requirements, and the type of your product. We would be happy to advise you on which standard—such as Siemens SN29500, IEC-TR-62380, or FIDES 2009—is most suitable for your application.
Can I have an existing MTBF calculation validated using field data?
Yes. Upon request, we compare calculated MTBF values with real field data to validate the results of your reliability analysis.
How does temperature affect the reliability of my product?
Higher operating temperatures generally increase the failure probability of electronic components. As part of the reliability analysis, we graphically present the MTBF trend over the relevant temperature range so that you can make well-founded design decisions.
For which industries is reliability analysis particularly relevant?
It is particularly important for industries with high safety requirements, such as the railway industry, medical technology, industrial automation, and aerospace – wherever failures can have critical consequences.
