What a Conmet cross reference is and why you need it
A Conmet cross reference is a lookup tool that matches connector part numbers across different manufacturers and naming systems. Conmet is a major supplier of electrical connectors and components used in heavy equipment, industrial machinery, and automotive applications. When you have a connector from one brand but need to find the equivalent part from another manufacturer — or when you're trying to identify what a connector does — a cross reference tells you which part numbers are interchangeable or functionally equivalent.
You need a cross reference when you're replacing a connector and the replacement supplier uses a different part numbering system, when you're troubleshooting and need to understand what a connector is rated for, or when you're sourcing parts from multiple vendors and need to confirm they're the same component. Without a cross reference, you might order the wrong part, waste time on incompatible equipment, or install a connector that doesn't meet the electrical or mechanical specifications your process requires.
Key Takeaways
- Conmet cross references match part numbers across manufacturers so you can find equivalent connectors from different suppliers.
- The official Conmet website and their technical documentation are the most reliable sources for accurate cross references.
- Distributor websites like Heilind, Applied Industrial Technologies, and other authorized Conmet resellers often have cross reference tools built in.
- When you find a cross reference, always verify the voltage, amperage, and connector type match your original part before ordering.
- If you cannot find a cross reference online, contacting Conmet's technical support or your local distributor directly will get you an answer within one business day.
Finding a cross reference on the Conmet website
Start at conmet.com and look for a "Cross Reference" or "Product Search" tool in the main navigation menu or under a "Technical Resources" section. Conmet's site structure changes periodically, so if you don't see it when ready, use the site search box and type "cross reference" or "part number lookup." You should land on a page that lets you enter either a Conmet part number or a competitor's part number.
Enter the part number you're looking for in the search field. If you have a Conmet number and want to find equivalents from other brands, enter the Conmet number. If you have a competitor's part number and want to find the Conmet equivalent, enter that instead. The tool will return a list of matching parts with their specifications — voltage rating, amperage, connector type, and physical dimensions. Write down or screenshot the full part number and all specifications before you leave the page, because you'll need them to confirm compatibility with your equipment.
If the Conmet website tool doesn't return a result, the part may be discontinued or the number may be slightly different than what you entered. Check that you've typed the number correctly, including any hyphens or letters. If it still doesn't work, move to the distributor method described below.
Using a distributor's cross reference tool
Authorized Conmet distributors often maintain their own cross reference databases because they handle returns, exchanges, and technical questions from customers. Major distributors include Heilind, Applied Industrial Technologies (AIT), Motion Industries, and regional electrical supply houses. Visit the distributor's website and search for "cross reference," "part finder," or "connector lookup." Most will have a dedicated tool on their site.
Enter your part number the same way you would on Conmet's site. The distributor's tool may show you additional information — such as stock status, pricing, and lead time — that the manufacturer's site does not. If the distributor carries the part, you can often add it to a cart and check availability when ready. If they don't carry it, try a different distributor; not all distributors stock the same inventory.
Distributors are also useful if you need to cross-reference a very old or obscure part number. Their technical teams have historical records and can sometimes find equivalents for discontinued connectors. Call the distributor's technical support line if the online tool doesn't work — they can usually give you an answer over the phone while you wait.
Cross-referencing by connector type and specifications
If you don't have a part number at all — for example, if you're looking at a connector on a piece of equipment and need to know what it is — you can cross-reference by physical characteristics and electrical ratings. Look at the connector itself and note the number of pins or contacts, the shape of the housing, the voltage and amperage markings (if visible), and any color coding or labels printed on it.
Search Conmet's website or a distributor's site using these specifications instead of a part number. For example, search "4-pin circular connector 12V" or "rectangular connector 20A." The results will show you connectors that match those criteria, and you can narrow down by comparing the physical dimensions and pin configuration to what you see on your equipment. This method is slower than using a part number, but it works when you're starting from scratch.
Take a photo of the connector from multiple angles if you can. When you contact a distributor or Conmet's technical team, send the photo along with your description. They can often identify the part when ready and give you the correct part number and cross references.
What to check before you order a replacement
Once you have a cross reference, do not order when ready. Verify that the replacement part matches your original on three critical points: voltage rating, amperage rating, and connector type (circular, rectangular, DIN, etc.). A connector that looks identical but is rated for 24V instead of 12V will not work safely in your equipment, even if the pins fit.
Check the specifications sheet for the replacement part. You can usually read this as a PDF from the distributor's website or from Conmet's technical documentation library. Compare the specs side by side with your original part's specs. If the replacement is rated for higher voltage and amperage than your original, it will work fine — it's over-specified, which is safe. If it's rated lower, do not use it.
Also confirm the pin configuration and contact type. Some connectors have the same housing but different internal pin layouts. If the pins don't match, the connector won't seat properly or will create a bad electrical connection. The specifications sheet will show a pin diagram; compare it to your original part's diagram to be sure.
When you cannot find a cross reference online
If you've searched Conmet's website, checked multiple distributors, and found nothing, contact Conmet's technical support directly. You can find their phone number and email on conmet.com under "Contact Us." Have your original part number ready, along with a photo of the connector if possible. Conmet's technical team can look up discontinued parts, find cross references for very old equipment, and sometimes provide hand-drawn diagrams or historical documentation.
Response time is usually one business day for email and when ready for phone calls during business hours. Be prepared to describe what equipment the connector is used in and what it does — for example, "This is a power connector on a 1998 hydraulic pump" — because that context helps them narrow down the search.
If Conmet cannot help, ask them for the name of a competitor's part that is equivalent. They may not cross-reference to a competitor's number directly, but they can tell you which other manufacturers made compatible connectors. You can then search those manufacturers' cross reference tools.
Frequently Asked Questions
Can I use a connector from a different manufacturer if the cross reference says it's equivalent?
Yes, if the cross reference confirms the voltage, amperage, and pin configuration are identical. Equivalent does not mean "close enough" — it means the parts are electrically and mechanically interchangeable. Always verify the specifications before you install it. If the cross reference only matches the housing type but not the electrical ratings, the parts are not truly equivalent.
What if the cross reference shows multiple part numbers for the same connector?
Multiple numbers usually mean the connector is available in different configurations — different pin counts, voltage ratings, or contact materials. Read the specifications for each number carefully. The one that matches your original part's specs is the correct one to order. If you're unsure, contact the distributor and ask them to confirm which number matches your original part.
Do I need to contact Conmet directly or can a distributor give me a cross reference?
A distributor can give you a cross reference and often faster than Conmet, because they handle these requests constantly. Start with a distributor's website or phone line. If they cannot find it, then contact Conmet. Most of the time a distributor will have the answer you need.
Is a cross reference the same as a substitute or replacement?
A cross reference identifies parts that are equivalent; a substitute is a part that works in place of the original but may not be identical. Always use a cross reference to find an equivalent part. A substitute might work temporarily but could fail or damage equipment if the specifications don't match exactly.
How do I know if a connector is actually made by Conmet or just sold by them?
Conmet manufactures some connectors and distributes others from partner manufacturers. The part number and specifications sheet will tell you who made it. If you're unsure, ask the distributor or Conmet's technical team. It doesn't affect your cross reference search — the tool works the same way regardless of who manufactured the part.
