Introducing the world's largest collection of electronic parts reliability failure rate data.

The new EPRD-2024 dataset will be available through a subscription to the Reliability Online Automated Databook System (ROADS)!

Harness the power of electronic parts component data for efficient and effective MTBFs, FMEAs, and more.

Subscribe to datasets used by engineers worldwide to meet reliability requirements for electronic and mechanical components.


Electronic Parts Reliability Data 2024 SUBSCRIBE NOW


The failure rate, mode/mechanism data you need for reliability analyses is only a subscription away.

Buy an annual subscription to EPRD-2024 and two additional datasets for $500.


You will view the data through ROADS, which is easily searchable and accessible directly in your web browser. No installation is required.


ROADS includes Quanterion Solutions’ popular databooks:

Electronic Parts Reliability Data (EPRD), including the upcoming EPRD-2024

Nonelectronic Parts Reliability Data (NPRD), including the newly updated NPRD-2023

Failure Mode / Mechanism Distributions (FMD)


Quickly find component failure rates/modes and mechanism data for your analyses using a searchable interface.


How the Data Is Used

Engineers around the world use the reliability data to:

  • Perform reliability analyses including:
    • Mean Time Between Failure (MTBF),
    • Failure Mode Effects Analysis (FMEA)
    • Failure Mode Effects and Criticality Analysis (FMECA),
    • And more.
  • Assess reliability requirement feasibility
  • Improve product and system reliability
  • Build reliability into new designs
  • Produce software for calculating reliability (ask about incorporating our data!)
  • And more!

How to Access the Data

It’s as easy as 1-2-3!

  1. Purchase a ROADS subscription. It costs $500 per user for one year.
  2. Instantly receive an email with your login details.
  3. Log in and search for the data you need.

That’s it! No installation required!

And the best part about getting started with ROADS? The steps are so easy that you don’t have to involve your IT department, and Quanterion Solutions (the ROADS developer and reliability data collector) is happy to help you if you have any questions.

You can always cancel your annual subscription anytime.

The ROADS interface has been recently updated, which means you can benefit from faster search capabilities. As a ROADS subscriber, you’ll have access to automatic feature and databook updates.*


Testimonial From a Current ROADS Subscriber

“It is easy to access online from my computer even if I am working from home. The Search has drop-downs to suggest nouns for items to help determine a good description of exactly the item I may be looking for. It also works by just starting to type a word which makes it pretty quick to find the item in a search.

“The failure modes listed for an item provide us with more confidence [when] we have considered all aspects of failure within our FMECA. Dates provided on the source help us determine if the data is relevant to our similar item, same for the Environment and quality fields.”

Gail F., Current ROADS Subscriber.
