Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SCHURTER 3404.2467.11 are qualified based on the following electrical and mechanical criteria:

Mandatory Matching Parameters:

• Current Rating: 1.25 A (exact match required)
• Response Time: Fast Blow (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Package Configuration: 2-SMD, Square End Block (mechanical compatibility required)

Allowable Parameter Variations:

• Voltage Rating - AC: May exceed 250 V (higher voltage rating provides equivalent or superior performance at rated voltage)
• Voltage Rating - DC: May exceed 125 V (higher voltage rating provides equivalent or superior performance at rated voltage)
• Breaking Capacity: May differ from specified values (determined by manufacturer design)
• Operating Temperature Range: May exceed -40°C ~ 85°C (wider range acceptable)
• Approval Agency: May differ (alternative certifications acceptable if product is active)
• Physical Dimensions: Minor variations acceptable within mechanical mounting constraints

The Eaton Electronics Division TR-1245UMFF1-25-R qualifies as a substitute because it maintains the mandatory parameters (1.25 A current rating, fast blow response, surface mount configuration, 2-SMD square end block package) while providing enhanced voltage ratings (350 V AC / 250 V DC) and extended operating temperature range (-40°C ~ 125°C).

Parameter Comparison

Engineering Selection Recommendations

SCHURTER 3404.2467.11 is the primary selection when:

• Circuit design specifies 250 V AC / 125 V DC voltage ratings
• Operating temperature range does not exceed 85°C
• cURus and VDE certifications are required
• Original equipment manufacturer (OEM) specifications mandate this exact part number
• Strip packaging is required for assembly processes

Eaton TR-1245UMFF1-25-R is an acceptable substitute when:

• Circuit design operates at or below 250 V AC / 125 V DC (the substitute's higher ratings provide margin)
• Operating temperature range extends to 125°C
• UL certification satisfies regulatory requirements
• Tape & Reel packaging is compatible with assembly equipment
• Both parts are active in production with established supply chains

Both parts are active products with current manufacturing status and established inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the Eaton TR-1245UMFF1-25-R be used in place of the SCHURTER 3404.2467.11?

A: Yes, the Eaton part qualifies as a substitute. Both parts share identical current ratings (1.25 A) and response time (fast blow). The Eaton part provides higher voltage ratings (350 V AC / 250 V DC versus 250 V AC / 125 V DC), which is acceptable in circuits designed for the lower voltage specification. Both are surface mount, 2-SMD square end block configurations suitable for equivalent mechanical mounting.

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

A: The primary differences are: (1) Voltage ratings—the Eaton part exceeds the SCHURTER specification; (2) Operating temperature range—the Eaton part extends to 125°C versus 85°C for the SCHURTER; (3) Approval agencies—SCHURTER carries cURus and VDE certifications while Eaton carries UL; (4) Physical dimensions—the Eaton part is slightly larger (12.00mm x 4.50mm x 4.50mm versus 11.30mm x 4.20mm x 4.00mm); (5) Packaging format—SCHURTER is supplied in strip format while Eaton is supplied in tape & reel format.

Q: Are there any mechanical compatibility concerns with the Eaton substitute?

A: The Eaton part is slightly larger in all three dimensions. Verify that the printed circuit board layout and mechanical mounting fixtures accommodate the larger footprint (12.00mm x 4.50mm x 4.50mm). Both parts use 2-SMD square end block configurations with equivalent clip-based mounting systems.

Q: Which certifications apply to each part?

A: The SCHURTER 3404.2467.11 carries cURus and VDE approvals. The Eaton TR-1245UMFF1-25-R carries UL approval. Both certifications are recognized for circuit protection applications. Verify that your application's regulatory requirements accept the applicable certification for your selected part.

Q: Can I use the SCHURTER part in a circuit designed for the Eaton part?

A: No. The SCHURTER part has lower voltage ratings (250 V AC / 125 V DC) and a narrower operating temperature range (maximum 85°C). If the circuit design specifies the Eaton part's higher voltage or temperature ratings, the SCHURTER part does not meet those specifications.

Q: What is the difference in packaging between strip and tape & reel formats?

A: Strip packaging supplies individual parts in a loose strip format suitable for manual assembly or small-batch operations. Tape & reel packaging supplies parts wound on continuous tape on a reel, optimized for automated pick-and-place assembly equipment. Verify your assembly process compatibility before selecting based on packaging format.
