MTBF (Mean Time Between Failure) predictions are a powerful tool for designing reliable products. Using a reliability calculator MTBF and advanced MTBF reliability prediction software, we help you assess performance and identify potential weak points before production. With the right MTBF formula and failure rate calculation, you can validate design requirements, improve reliability, and set accurate warranty periods.

Get Precision in Every Calculation with MTBF Models

At Relteck, we use industry-standard MTBF models like MIL-HDBK-217F, Telcordia SR-332, NSWC, NPRD95, and 217 Plus to ensure accuracy and reliability in every prediction. These models cater to a wide range of industries, from military and aerospace to commercial electronics, allowing us to tailor failure rate calculations to your product’s specific environment.

Whether it’s pre-production, production, or operational MTBF, our approach evolves with your design. Starting with basic part type and count information, we refine predictions as your design progresses, incorporating thermal and stress analysis for pinpoint accuracy.

Our advanced tools also include burn-in, assembly, and field performance data, ensuring your MTBF calculations provide actionable insights at every stage of development. With Relteck, you get precision you can trust in every step of your product’s journey.

Leverage COTS Components, PiQ Factors, and the VITA Advantage

The ANSI/VITA 51.1-2008 MTBF Prediction standard offers a modern solution for evaluating product reliability, addressing gaps in the outdated MIL-HDBK-217FN2 by incorporating advancements in electronics for more realistic failure rate predictions. A key update is the tailored adjustment of PiQ factors for COTS components, moving beyond the overly conservative PiQ factor of 10 used in MIL-HDBK-217FN2. The VITA standard ensures reliability calculations align with today’s technology, enabling engineers to deliver precise and actionable results.

Plan Smarter With Mean Time Between Failures

MTBF (Mean Time Between Failures) analysis is a key tool for understanding the reliability and performance of your systems. It calculates the average time between failures, giving you valuable insights into how long your equipment is likely to last. With accurate MTBF testing and precise MTBF calculations, you can spot potential issues early and make your products more reliable. A thorough MTBF analysis helps you plan maintenance better, reduce downtime, and save on long-term costs.

The Importance of MTBF Calculations

MTBF (Mean Time Between Failures) is a critical measure for identifying and addressing weak points in your systems. It helps target improvements, boosting reliability and optimizing performance. With accurate insights, you can make smarter decisions about warranty periods, spare parts inventory, and long-term cost planning.

MTBF analysis also plays a key role in risk management, uncovering potential failure patterns and guiding better choices in product design and production. The data from an MTBF report can improve operational efficiency, reduce downtime costs, and enhance customer satisfaction by ensuring dependable, high-quality products.

How You Can Benefit From MTBF Calculations

MTBF (Mean Time Between Failures) calculations are a powerful tool for improving product reliability and performance. By analyzing potential failure points early, you can enhance your design, reduce risks, and create a product that performs consistently.

With accurate MTBF predictions, you can:

  • Build more reliable products that meet customer expectations.
  • Identify and address weak points before production begins.
  • Plan maintenance schedules to minimize downtime.
  • Optimize long-term costs with better reliability insights.

MTBF Prediction Process (Parts Stress Analysis)

MTBF prediction for parts stress analysis provides a detailed look at how components perform under real-world conditions, factoring in environmental stress, electrical loads, material quality, and temperature effects. This precise method helps identify potential weaknesses, optimize designs, and enhance overall system reliability. At Relteck, we deliver accurate MTBF predictions to ensure your products are built to last.

MTBF Prediction Process (Part Count Analysis)

Part count analysis is a straightforward method for MTBF (Mean Time Between Failures) prediction, often used in the early stages of design. It calculates system reliability by summing up the failure rates of individual components based on their type and quantity.

This approach requires minimal data, such as part categories and counts, making it ideal for preliminary evaluations before detailed designs are available. While less precise than parts stress analysis, part count analysis provides a quick estimate of system reliability and helps guide early design decisions.

Relteck uses industry-standard tools and techniques to perform accurate part counts MTBF predictions, giving you valuable insights to refine your design and improve product reliability from the start.

Product Electronics Derating Process

Relteck’s product electronics derating process is built to optimize reliability and performance by carefully analyzing detailed data, including your Bill of Materials (BOM) and electrical schematics.

Unlike generic approaches, our comprehensive evaluation considers critical factors like electrical loads, thermal stress, material quality, and mechanical durability to provide a full understanding of component performance. 

By identifying stress points early, we proactively mitigate risks, allowing for design adjustments that prevent failures before they occur. Through precise derating criteria, we ensure your product operates well within safe thresholds, enhancing both reliability and lifespan.

Understanding MTBF With Key Definitions & Insights

MTBF (Mean Time Between Failures) is a critical measure in reliability engineering, helping predict product performance and lifespan. 

Here’s how Relteck incorporates these key concepts to deliver actionable insights:

  1. MTBF (Mean Time Between Failures): Calculated in hours, MTBF estimates the reliability of a product by measuring the average time between failures. It is determined using the formula MTBF = 1/λ (failure rate).
  2. MTTF (Mean Time To Failure): Often used for non-repairable units, MTTF predicts the expected lifespan before a product fails.
  3. Failure Rate (λ): Expressed as a function of time, this rate calculates how frequently failures occur in a given period.
  4. Reliability (R): Defined as the probability that a product will perform without failure for a specific time.


Relteck
uses these metrics to deliver detailed MTBF analysis tailored to your product. This includes failure rate evaluations, reliability projections, and actionable recommendations to enhance performance and reduce risks.

Question

What is the predicted reliability for a unit that has a useful life of 5 years and an MTBF rating of 500,000 HRS?

Answer

R = 2.718 ^- (8760*5/500,000) =.916 or 91.6% of the units will still be failure free.
8.4 % will have failed.
