Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete SCHURTER 7010.9810.53 is determined by strict equivalence across the following electrical and mechanical parameters:

• Current Rating: 1 A (exact match required)
• Voltage Rating: 125 V AC and 125 V DC (both must match)
• Fuse Type: Cartridge, Ceramic (form factor and material)
• Response Time: Fast Blow (thermal response characteristic)
• Mounting Type: Surface Mount (assembly compatibility)
• Breaking Capacity: 300 A @ rated voltage (fault protection capability)
• Melting I²t: 0.11 (thermal energy threshold)
• Operating Temperature Range: -55°C to 125°C (environmental compatibility)
• Physical Dimensions: 0.079" Dia x 0.276" L / 2.00 mm x 7.00 mm (mechanical fit)
• Approval Agency: cURus (regulatory compliance)

Substitute parts must satisfy all parameters listed above without deviation.
