Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete SCHURTER 2030.0249 is determined by strict equivalence across the following electrical and mechanical parameters:

• Current Rating: 750mA (exact match required)
• Voltage Rating: 125VAC and 125VDC (both ratings must be met)
• Mounting Type: Through Hole (physical installation compatibility)
• Fuse Type: Board Mount (form factor requirement)
• Response Time: Fast Blow (circuit protection characteristic)
• Breaking Capacity: 100A at rated voltage (fault handling capability)
• Operating Temperature Range: -25°C to 85°C (environmental specification)
• Physical Dimensions: 0.252" Dia x 0.346" (6.40mm x 8.80mm) (PCB footprint compatibility)
• Melting I²t: 0.02 (thermal energy rating)

The SCHURTER 0034.4249 meets all these criteria and is classified as a direct substitute.

Frequently Asked Questions (FAQ)

Q: Can the SCHURTER 0034.4249 be used as a direct replacement for the 2030.0249 in existing designs?

A: Yes. The 0034.4249 meets all electrical and mechanical parameters of the 2030.0249, including current rating (750mA), voltage ratings (125VAC/125VDC), mounting type (through hole), response time (fast blow), breaking capacity (100A), and physical dimensions (0.252" Dia x 0.346"). Both components are cURus approved and ROHS3 compliant.

Q: Are there any differences in package configuration between these parts?

A: The 2030.0249 specifies Radial, Can, Vertical packaging, while the 0034.4249 specifies Radial, Can packaging. Both configurations are compatible for through-hole board mount applications. The physical dimensions remain identical at 0.252" Dia x 0.346" (6.40mm x 8.80mm).

Q: What is the significance of the "Cartridge Style Excluded" notation on the 0034.4249?

A: This notation clarifies that the 0034.4249 is a board mount fuse excluding cartridge-style configurations. The part maintains the same radial, can form factor as the 2030.0249, ensuring mechanical and electrical compatibility.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the 2030.0249 and 0034.4249 carry cURus approval, are ROHS3 compliant, and maintain REACH unaffected status. Both are classified under ECCN EAR99 and HTSUS 8536.10.0040.

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

A: The melting I²t value of 0.02 represents the thermal energy required to melt the fuse element. Both parts share this identical value, ensuring equivalent thermal protection characteristics and circuit behavior under fault conditions.

Q: Is the 0034.4249 available for immediate procurement?

A: The 0034.4249 is listed as active product status with 998 pieces in current inventory stock, available in bulk packaging. The 2030.0249 is obsolete with 1024 pieces in stock.
