SCHURTER 7010.7120.49 Board Mount Fuse Equivalent & Substitute Parts

Part Overview

The SCHURTER 7010.7120.49 is a 4A 125VAC board mount fuse with axial through-hole mounting. This component is classified as obsolete, necessitating identification of active equivalent alternatives for new designs and ongoing production requirements. The fuse features fast-blow response characteristics and is rated for 300A breaking capacity at rated voltage. Substitute parts must maintain identical electrical ratings and mechanical compatibility to ensure proper circuit protection without design modification.

Substitute Part Grouping Explanation

Substitution of the obsolete 7010.7120.49 is determined by strict equivalence across the following parameters: current rating (4A), AC voltage rating (125V), response time (fast blow), mounting configuration (through-hole axial cartridge), physical dimensions (0.093" Dia x 0.315" L), breaking capacity (300A), and melting I²t value (4). All substitute parts must maintain these electrical and mechanical specifications without deviation. The SCHURTER 172322 series provides active alternatives meeting these criteria.
