Substitute Part Grouping Explanation

Substitution of the SCHURTER 2030.0014 is determined by strict equivalence across the following critical parameters:

• Current Rating: 315mA (exact match required)
• Voltage Rating: 125 VAC and 125 VDC (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)
• Operating Temperature Range: -25°C to 85°C (exact match required)
• Melting I²t: 0.025 (exact match required)
• Physical Dimensions: 0.252" Dia x 0.346" (exact match required)
• Regulatory Compliance: cURus approval and ROHS3 compliance (exact match required)

The SCHURTER 0034.4214 meets all substitution criteria as an active product within the MSF 125 series, providing direct functional and electrical equivalence to the obsolete 2030.0014.

Parameter Comparison

Engineering Selection Recommendations

The SCHURTER 0034.4214 is the direct equivalent for the obsolete 2030.0014. Both components are manufactured by SCHURTER Inc. and maintain identical electrical specifications, mechanical dimensions, and regulatory certifications. The 0034.4214 is currently in active production status with 880 pieces available in inventory, whereas the 2030.0014 is obsolete with limited stock (1049 pieces).

Selection of the 0034.4214 is supported by:

• Identical current rating, voltage ratings, and breaking capacity
• Matching operating temperature range and thermal characteristics (Melting I²t = 0.025)
• Identical through-hole mounting configuration and physical dimensions
• Equivalent fast-blow response time for circuit protection
• Matching cURus approval and ROHS3 compliance certifications
• Active product status ensuring long-term availability and supply chain continuity

Frequently Asked Questions (FAQ)

Q: Can the SCHURTER 0034.4214 be used as a direct replacement for the 2030.0014 in existing designs?

A: Yes. The 0034.4214 is electrically and mechanically equivalent to the 2030.0014 across all critical parameters including current rating, voltage ratings, breaking capacity, response time, and physical dimensions. Both components are cURus approved and ROHS3 compliant.

Q: What is the difference between the MSU 125 series (2030.0014) and the MSF 125 series (0034.4214)?

A: Both series are SCHURTER board mount fuse lines. The MSF 125 series (0034.4214) is the active product line, while the MSU 125 series (2030.0014) is obsolete. The electrical and mechanical specifications are identical for these specific part numbers.

Q: Are the physical dimensions identical between these two parts?

A: Yes. Both the 2030.0014 and 0034.4214 have identical dimensions of 0.252" diameter by 0.346" length (6.40mm x 8.80mm) in radial, can configuration suitable for through-hole board mounting.

Q: What is the melting I²t value, and why is it important for substitution?

A: The melting I²t value of 0.025 represents the thermal energy required to melt the fuse element. Both parts share this identical value, ensuring equivalent thermal response and protection characteristics in circuit applications.

Q: Are there any packaging differences between the main part and substitute?

A: The 2030.0014 is available in standard packaging, while the 0034.4214 is supplied in bulk packaging. This does not affect electrical or mechanical compatibility; it only impacts order quantities and handling procedures.

Q: What regulatory certifications apply to both parts?

A: Both the 2030.0014 and 0034.4214 carry cURus approval and are ROHS3 compliant. Both are classified as REACH Unaffected and carry ECCN EAR99 designation.
