Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCHURTER 3404.2471.11 is determined by the following critical parameters:

• Current Rating: Must be 3.15 A (exact match required for circuit protection integrity)
• Mounting Type: Surface Mount (SMD) configuration mandatory
• Fuse Type: Board Mount (Cartridge Style Excluded)
• Response Time: Fast Blow characteristic
• Package Configuration: 2-SMD, Square End Block format

The identified substitute part TR-1245UMFF3-15-R (Eaton - Electronics Division) meets all core electrical and mechanical compatibility criteria. This substitute maintains the 3.15 A current rating and fast-blow response while offering enhanced voltage ratings (350 V AC / 250 V DC versus 250 V AC / 125 V DC), making it suitable for applications requiring higher voltage margin. Both parts utilize surface mount technology with compatible board-mount configurations.

Parameter Comparison

Engineering Selection Recommendations

SCHURTER 3404.2471.11 is the primary selection for applications with voltage requirements of 250 V AC / 125 V DC. This part carries cURus and VDE certifications, ensuring compliance with European and North American regulatory standards. The compact form factor (11.30 mm x 4.20 mm x 4.00 mm) and integrated clip design optimize PCB space utilization. Bulk packaging supports prototyping and low-volume production environments.

Eaton TR-1245UMFF3-15-R serves as a direct substitute when higher voltage margins are required (350 V AC / 250 V DC) or when extended operating temperature range (-40°C ~ 125°C) is specified. UL certification provides alternative regulatory compliance pathway. The slightly larger footprint (12.00 mm x 4.50 mm x 4.50 mm) requires PCB layout verification. Tape & Reel packaging is optimized for automated assembly and high-volume production. Both parts maintain identical 3.15 A current rating and fast-blow response, ensuring equivalent circuit protection performance.

Frequently Asked Questions (FAQ)

Q: Can TR-1245UMFF3-15-R be used as a direct replacement for SCHURTER 3404.2471.11?

A: Yes, for applications operating at or below 250 V AC / 125 V DC. The substitute maintains the 3.15 A current rating and fast-blow response. Physical dimensions differ slightly (12.00 mm vs. 11.30 mm length), requiring PCB layout verification before implementation.

Q: What are the key differences between these two fuses?

A: The primary differences are voltage ratings (SCHURTER: 250 V AC / 125 V DC; Eaton: 350 V AC / 250 V DC), operating temperature range (SCHURTER: -40°C ~ 85°C; Eaton: -40°C ~ 125°C), approval agencies (SCHURTER: cURus/VDE; Eaton: UL), and physical dimensions. Current rating and response time are identical.

Q: Are there packaging considerations when switching between these parts?

A: Yes. SCHURTER 3404.2471.11 is supplied in Bulk packaging, while Eaton TR-1245UMFF3-15-R is supplied in Tape & Reel format. This affects procurement quantities, storage, and assembly line integration. Verify your production process compatibility before selection.

Q: Which certifications apply to each part?

A: SCHURTER 3404.2471.11 carries cURus and VDE approvals. Eaton TR-1245UMFF3-15-R carries UL approval. Select based on your regional regulatory requirements and end-product certification pathway.

Q: Can I use the SCHURTER part in an application rated for 350 V AC?

A: No. The SCHURTER 3404.2471.11 is rated for 250 V AC maximum. Using it in a 350 V AC application exceeds its voltage rating and compromises safety and reliability. Use Eaton TR-1245UMFF3-15-R for 350 V AC applications.
