Substitute Part Grouping Explanation

Substitution eligibility for the SCHURTER 3410.0021.03 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part 3410.0021.02 qualifies as a direct equivalent based on the following criteria:

  • Identical current rating: 200 mA
  • Identical voltage ratings: 125 V AC and 125 V DC
  • Identical response time classification: Fast Blow
  • Identical mounting type: Surface Mount
  • Identical package configuration: 2-SMD, Square End Block
  • Identical breaking capacity: 50 A AC, 300 A DC
  • Identical melting I²t value: 0.0008
  • Identical DC cold resistance: 1.02 Ohms
  • Identical operating temperature range: -55°C to 150°C
  • Identical physical dimensions: 0.126" L × 0.061" W × 0.061" H
  • Identical approval agency certification: cURus
  • Identical RoHS compliance status: ROHS3 Compliant
  • Same manufacturer: SCHURTER Inc.
  • Same series designation: MGA

Both parts are Active product status with full regulatory compliance. The substitute differs only in packaging revision level (revision .02 versus .03), which does not affect electrical performance or mechanical compatibility.
