Can Category 5 RJ45 connectors be used with Category 6 cables?

2025-08-01

Many friends mentioned that it can be used, and some friends said it cannot be used. For this reason, I also experimented and found that it is indeed possible to use Category 6 cables to insert Category 5 crystal plugs, and it can be used. However, it is more difficult to insert Category 6 cables with sufficient wire diameter into the crystal plug, and some may still not be able to be inserted.

 

 

A key evaluation criterion for network cable performance is stability, not whether it's immediately operational.

The copper core of Category 6 network cable is between 0.56mm and 0.58mm. The copper core of Category 5e network cable is 0.46mm-0.51mm. The copper core of Category 5 network cable is approximately 0.45mm.

There are quite a few differences in the cable cores. If you use a Category 5 connector with a Category 6 cable, you must press it very tightly. If you press too hard, the metal plate inside the connector will collapse. After long-term use, it may cause poor contact and affect the transmission distance. It is also easy to crack. If you don't notice it at the time, the transmission may be intermittent later, which is easy to cause failure. 

 

Will using a Category 6 cable with a Category 5 connector increase speed? Besides whether it can be used, there's also the issue of speed. Using a Category 6a cable with a Category 5 connector will reduce network speed and signal quality. Category 6a cables are designed for high-speed transmission and superior signal transmission. Using low-quality Category 5 connectors will limit the cable's performance, resulting in reduced network speed, increased latency, and poor signal quality.

This configuration is definitely not suitable for dedicated network transmission and is only adequate for limited-route surveillance.

Therefore, this is not a long-term solution and is likely to cause unexpected disconnections and other problems, making it difficult to identify the cause.

 

For optimal performance, use matching connectors with the Category 6a cable.
