Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCHURTER 3404.2468.11 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Current Rating: 1.6 A (exact match required)
• Response Time: Fast Blow (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Fuse Type: Board Mount (Cartridge Style Excluded) (exact match required)
• Package / Case: 2-SMD, Square End Block configuration (exact match required)

Allowable Variation Parameters:

• Voltage Rating - AC: Equal to or greater than 250 V
• Voltage Rating - DC: Equal to or greater than 125 V
• Operating Temperature Range: Equal to or greater than -40°C ~ 85°C
• Breaking Capacity: Equal to or greater than specified values
• Physical Dimensions: Minor variations acceptable within SMD standard tolerances
• Approval Agency: Alternative recognized certifications acceptable

Parameter Comparison

Engineering Selection Recommendations

The Eaton TR-1245UMFF1-6-R is a valid substitute for the SCHURTER 3404.2468.11 based on the following engineering criteria:

Electrical Compatibility: Both parts share identical current ratings (1.6 A) and fast blow response characteristics. The Eaton substitute provides higher voltage ratings (350 V AC / 250 V DC versus 250 V AC / 125 V DC), making it suitable for applications requiring the original part's specifications or higher voltage environments.

Mechanical Compatibility: Both parts are surface mount, board mount fuses in 2-SMD square end block configurations. Physical dimension variations (11.30 mm x 4.20 mm x 4.00 mm versus 12.00 mm x 4.50 mm x 4.50 mm) are within acceptable SMD tolerances and do not preclude PCB layout compatibility for standard footprint designs.

Regulatory Compliance: The SCHURTER part carries cURus and VDE certifications. The Eaton substitute carries UL certification. Both certifications are recognized for circuit protection applications. Selection between these parts may depend on specific regional or customer certification requirements.

Thermal Performance: The Eaton substitute operates across a wider temperature range (-40°C ~ 125°C versus -40°C ~ 85°C), providing additional thermal margin for applications with elevated ambient conditions.

Product Status: Both parts are active in production with confirmed inventory availability, ensuring supply chain reliability.

Frequently Asked Questions (FAQ)

Q: Can the Eaton TR-1245UMFF1-6-R be used as a direct replacement for the SCHURTER 3404.2468.11?

A: Yes, the Eaton part is electrically and mechanically compatible. Both parts have identical current ratings (1.6 A) and fast blow response times. The Eaton substitute exceeds the voltage and thermal specifications of the original part. Physical dimensions vary slightly but remain within standard SMD tolerances.

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

A: The primary differences are voltage ratings (Eaton provides 350 V AC / 250 V DC versus SCHURTER's 250 V AC / 125 V DC), operating temperature range (Eaton: -40°C ~ 125°C versus SCHURTER: -40°C ~ 85°C), physical dimensions (Eaton: 12.00 mm x 4.50 mm x 4.50 mm versus SCHURTER: 11.30 mm x 4.20 mm x 4.00 mm), and approval certifications (Eaton: UL versus SCHURTER: cURus, VDE).

Q: Will the slightly larger Eaton fuse fit on my PCB designed for the SCHURTER part?

A: PCB compatibility depends on your specific footprint design and available board space. The dimension increase (approximately 0.7 mm in length and width) may require footprint adjustment. Consult your PCB layout documentation and design guidelines for SMD component spacing.

Q: Which certification should I choose for my application?

A: Selection depends on your regional requirements and customer specifications. The SCHURTER part carries cURus and VDE certifications, suitable for North American and European markets. The Eaton part carries UL certification, recognized in North American applications. Verify your application's certification requirements before final selection.
