The minimum cable type for 10BASE-T is Category 3 (Cat 3) twisted pair cable. This standard supports data rates of up to 10 Mbps and a maximum distance of 100 meters. While Cat 3 is the minimum requirement, higher category cables like Cat 5 or Cat 5e can also be used for better performance and future-proofing.
Rj 45 refers to the ends of the cable. The type of end it has. The cable itself is cat 5.
The modern Ethernet cable is a Category 5 UTP cable, with an RJ 45 connector.
