Key Parameters

Substitute Part Grouping Explanation

Substitution of the 7040.3180 is constrained by the following critical parameters:

Mandatory Matching Parameters:

• Current Rating: 8 A (exact match required)
• Package / Case: 5mm x 20mm (physical form factor compatibility with existing holders)
• Response Time: Slow Blow (functional behavior for transient protection)
• Mounting Type: Requires Holder (installation method compatibility)

Voltage Consideration: The main part operates at 125VAC. Substitute parts must maintain voltage ratings sufficient for the application circuit. Higher voltage-rated substitutes are acceptable when the application voltage does not exceed the substitute's rating.

Material Consideration: The main part uses glass construction. Ceramic alternatives with identical electrical ratings and form factors are functionally equivalent for the same application circuits, provided the ceramic material meets the same approval standards.

Parameter Comparison

Engineering Selection Recommendations

The SCHURTER 0001.2513 is a direct functional substitute for the 7040.3180 based on the following criteria:

Electrical Compatibility: Both parts share identical 8A current ratings and slow-blow response characteristics. The 0001.2513 provides higher voltage ratings (250VAC / 150VDC) compared to the main part (125VAC), making it suitable for applications operating at or below 125VAC. The increased breaking capacity (1kA AC vs. 50A) provides enhanced fault protection capability.

Physical Compatibility: Both parts maintain the 5mm x 20mm form factor, ensuring compatibility with existing fuse holder installations without mechanical modification.

Regulatory & Compliance Status: The 0001.2513 holds active product status with cURus and VDE certifications, compared to the obsolete 7040.3180 with UR certification. Both are ROHS3 compliant and REACH unaffected. The substitute's broader certification scope supports long-term supply chain continuity.

Material Difference: The substitute uses ceramic construction versus the main part's glass construction. Ceramic fuses provide superior thermal stability and wider operating temperature range (-55°C ~ 125°C vs. -40°C ~ 70°C), beneficial for applications in variable environmental conditions.

Thermal Characteristics: The lower melting I²t value of the 0001.2513 (268 vs. 1400) indicates faster thermal response. This difference must be evaluated against specific circuit protection requirements to ensure nuisance trip prevention in the target application.

Frequently Asked Questions (FAQ)

Q: Can the 0001.2513 directly replace the 7040.3180 in my circuit?

A: Yes, for applications operating at 125VAC or below. Both parts have identical 8A current ratings, slow-blow response times, and 5mm x 20mm form factors. The substitute's higher voltage rating (250VAC) does not prevent operation in lower-voltage circuits. Verify that your fuse holder is compatible with both glass and ceramic cartridge types if switching materials.

Q: What is the difference between glass and ceramic fuses?

A: Glass fuses (7040.3180) and ceramic fuses (0001.2513) both provide overcurrent protection with identical electrical ratings in this case. Ceramic construction offers wider operating temperature range and superior thermal stability. Both materials are suitable for standard industrial and commercial applications.

Q: Why does the 0001.2513 have a lower melting I²t value?

A: The melting I²t (268 vs. 1400) reflects the thermal mass and response speed of each fuse element. The 0001.2513's lower value indicates faster thermal response to overcurrent conditions. For applications with high inrush currents or transient surges, verify that the substitute's thermal characteristics do not cause nuisance trips in your specific circuit.

Q: Are both parts RoHS compliant?

A: Yes. Both the 7040.3180 and 0001.2513 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What certifications does each part hold?

A: The 7040.3180 holds UR certification. The 0001.2513 holds cURus and VDE certifications. The substitute's broader certification scope supports compliance in markets requiring VDE or cURus approval.

Q: Can I use the 0001.2513 in DC circuits?

A: The 0001.2513 is rated for 150VDC, making it suitable for DC applications at or below this voltage. The main part (7040.3180) does not specify a DC rating. Verify your circuit's DC voltage requirements before selection.
