Fuse & Circuit Breaker Cross Reference Tool for Replacement Parts
Okay… we recognize that we didn’t invent the fuse, nor have we been in business since 1927 like some of the more established manufacturers in the industry. What that really means is simply that those companies had a head start in the market—that’s all.
So in many cases, the fuse or circuit breaker you are trying to replace is not an OptiFuse part, but instead a product from Bussmann or Littelfuse. That’s a common situation when working with legacy equipment and existing installations.
The good news is that our fuse cross reference tool is designed to remove the guesswork from finding the correct replacement fuse.
Fuse Replacement Cross Reference Tool
We offer a robust fuse replacement cross reference tool that helps you quickly identify the correct OptiFuse equivalent. It is comprehensive, continuously expanding as new parts are added, and designed to be very easy to use.
Whether you are searching for a fuse cross reference across manufacturers such as Bussmann, Littelfuse, Mersen, Blue Sea, Egis, or Keystone, the tool is designed to simplify the process and help you quickly identify the correct OptiFuse equivalent.
How to Find a Fuse Replacement
There are two simple ways to use the OptiFuse cross reference system:
You can enter the competitor’s part number directly into the lookup field in the search bar at the top of our website. A partial part number will often return results as well.
If no results appear when using the complete part number, try searching with just the base part number instead. Many manufacturers add packaging-specific suffixes or other variations to their part numbers that are not required to identify the correct replacement. Using the base part number will often return the correct match.
This is the fastest way to find a fuse replacement cross reference when you already have an existing part number.
You can also access our Cross-Reference resources through dedicated guides organized by both industry and competitor to make selection faster and more accurate. Available guides include:
- Transportation Cross Reference Guide
- Electronics Cross Reference Guide
- Industrial Cross Reference Guide
Additional documents are also available by competitor, including cross reference guides for manufacturers such as Bussmann, Littelfuse, Mersen, Blue Sea Systems, Egis, and Keystone.
