Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete SCHURTER 2030.0255 is based on strict electrical and mechanical parameter matching:

Critical Matching Parameters:

• Current Rating: 2.5A
• Voltage Rating: 125 VAC / 125 VDC
• Response Time: Fast Blow
• Mounting Type: Through Hole
• Fuse Type: Board Mount
• Package Configuration: Radial, Can
• Physical Dimensions: 0.252" Dia x 0.346" (6.40mm x 8.80mm)
• Breaking Capacity: 100A
• Melting I²t: 0.6
• Operating Temperature: -25°C ~ 85°C
• Regulatory Compliance: cURus approval, ROHS3 Compliant, REACH Unaffected

The SCHURTER 0034.4255 meets all critical electrical and mechanical parameters, differing only in series designation (MSF 125 vs. MSU 125) and product status (Active vs. Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The SCHURTER 0034.4255 is the direct functional equivalent for the obsolete 2030.0255.

Frequently Asked Questions (FAQ)

Q: Can the SCHURTER 0034.4255 be used as a direct replacement for the 2030.0255?

A: Yes. Both parts share identical current ratings (2.5A), voltage ratings (125 VAC/125 VDC), response time (Fast Blow), breaking capacity (100A), melting I²t (0.6), operating temperature range (-25°C ~ 85°C), physical dimensions (0.252" Dia x 0.346"), and regulatory certifications (cURus, ROHS3, REACH Unaffected). The substitute part is functionally equivalent for all electrical and mechanical applications.

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

A: The main part belongs to the MSU 125 series (obsolete), while the substitute belongs to the MSF 125 series (active). Both series share identical electrical specifications and physical form factors. The series designation change reflects SCHURTER's product line evolution, with MSF 125 representing the current production equivalent.

Q: Are there any packaging differences between these parts?

A: The main part is specified with packaging as "-" (undefined), while the substitute is supplied in Bulk packaging. Both maintain identical through-hole radial mounting configuration and physical dimensions suitable for PCB assembly.

Q: Do both parts meet current regulatory compliance?

A: Yes. Both the 2030.0255 and 0034.4255 are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards for electronic component procurement.

Q: What is the breaking capacity specification?

A: Both parts have a breaking capacity of 100A at rated voltage (125 VAC/125 VDC), indicating the maximum fault current the fuse can safely interrupt without component failure or hazard.
