SCHURTER 0034.4222 Equivalent & Substitute Parts

Part Overview

The SCHURTER 0034.4222 is a board mount fuse rated for 1.25 A at 125 V AC/DC with fast blow response characteristics. This through-hole radial cartridge-style fuse is designed for circuit protection in electronic assemblies requiring reliable overcurrent interruption. The part maintains active product status with full cURus approval and ROHS3 compliance, ensuring continued availability and regulatory alignment for new designs and production environments.

Substitute parts are identified when component availability becomes constrained, supply chain disruptions occur, or inventory optimization is required while maintaining identical electrical and mechanical performance specifications.

• Current Rating: 1.25 A
• Voltage Rating (AC/DC): 125 V
• Response Time: Fast Blow
• Mounting Type: Through Hole
• Fuse Type: Board Mount (Cartridge Style Excluded)
• Package / Case: Radial, Can
• Breaking Capacity @ Rated Voltage: 100 A
• Melting I²t: 0.12
• Operating Temperature Range: -25°C ~ 85°C
• Physical Dimensions: 0.252" Dia x 0.346" H (6.40mm x 8.80mm)
• Regulatory Compliance: cURus approval, ROHS3 Compliant, REACH Unaffected

Only parts meeting all specified parameters are classified as direct equivalents. No parameter deviation is permitted for substitution eligibility.
