Littelfuse 0315.600MXP Equivalent & Substitute Parts

Part Overview

The Littelfuse 0315.600MXP is a 600 mA, 250 V AC/DC slow-blow glass cartridge fuse with 3AB/3AG package configuration. This through-hole component is designed for circuit protection in applications requiring moderate current ratings and slow-blow response characteristics. The part maintains active product status with full compliance to CE, CSA, and UL approval agencies. Substitute parts are identified when identical electrical and mechanical parameters are required for design flexibility, inventory management, or supply chain continuity.
