Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCHURTER 2030.0018 is determined by strict equivalence across the following critical parameters:

• Current Rating: 710mA (exact match required)
• Voltage Rating: 125VAC / 125VDC (exact match required)
• Mounting Type: Through Hole (exact match required)
• Fuse Type: Board Mount (exact match required)
• Response Time: Fast Blow (exact match required)
• Breaking Capacity: 100A at rated voltage (exact match required)
• Melting I²t: 0.045 (exact match required)
• Physical Dimensions: 0.252" Dia x 0.346" (exact match required)
• Approval Agency: cURus certification (exact match required)
• Operating Temperature: -25°C to 85°C (exact match required)

The SCHURTER 0034.4218 meets all substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The SCHURTER 0034.4218 is the direct equivalent substitute for the obsolete SCHURTER 2030.0018. Both components are manufactured by SCHURTER Inc. and maintain identical electrical and mechanical specifications across all critical parameters.

Selection of the 0034.4218 is supported by:

• Exact electrical equivalence: 710mA current rating, 125VAC/125VDC voltage rating, 100A breaking capacity, and 0.045 melting I²t
• Identical mechanical compatibility: Through-hole mounting, radial can package, and 0.252" Dia x 0.346" dimensions
• Matching thermal performance: -25°C to 85°C operating temperature range
• Equivalent regulatory compliance: cURus approval, ROHS3 compliance, REACH unaffected status, and EAR99 export classification
• Active product status: The 0034.4218 is currently in active production, ensuring long-term availability and supply chain continuity

The 0034.4218 operates within the MSF 125 series, representing an evolution of the MSU 125 series platform while maintaining full backward compatibility through identical performance parameters.

Frequently Asked Questions (FAQ)

Q: Can the SCHURTER 0034.4218 be used as a direct replacement for the 2030.0018 in existing designs?

A: Yes. The 0034.4218 meets all electrical and mechanical specifications of the 2030.0018, including current rating, voltage rating, breaking capacity, response time, mounting type, and physical dimensions. Both components carry cURus approval and ROHS3 compliance.

Q: What is the difference between the MSU 125 and MSF 125 series?

A: The MSU 125 series (2030.0018) is obsolete. The MSF 125 series (0034.4218) represents the active product line. Both series maintain identical electrical and mechanical performance for the 710mA 125VAC/125VDC rating.

Q: Are there any package or mounting differences between these parts?

A: Both components use radial, can-style through-hole mounting with identical dimensions of 0.252" Dia x 0.346". The 0034.4218 specifically excludes cartridge-style variants, but maintains full compatibility with the original 2030.0018 package specification.

Q: What certifications apply to the substitute part?

A: The 0034.4218 carries cURus approval, ROHS3 compliance, REACH unaffected status, and EAR99 export classification, matching the regulatory profile of the original 2030.0018.

Q: Is the 0034.4218 currently available?

A: Yes. The 0034.4218 is an active product with current manufacturing status, ensuring availability for new designs and replacement applications.
