Key Parameters

Substitute Part Grouping Explanation

The SCHURTER 0001.2511 qualifies as a substitute for the 7040.3160 based on the following critical parameters:

• Current Rating: Both parts are rated at 5 A, ensuring identical load protection characteristics
• Physical Form Factor: Both utilize 5mm x 20mm cartridge dimensions, enabling direct mechanical compatibility with existing holders
• Response Time: Both employ slow-blow characteristics, maintaining identical circuit protection behavior
• Mounting Configuration: Both require a holder assembly, preserving installation methodology
• RoHS Compliance: Both meet ROHS3 requirements, satisfying environmental regulatory obligations

The substitute part (0001.2511) operates at higher voltage ratings (250V AC / 150V DC) and ceramic construction, making it suitable for applications within the original part's voltage envelope while providing expanded capability for higher-voltage systems.

Parameter Comparison

Engineering Selection Recommendations

The SCHURTER 0001.2511 is the designated substitute for the obsolete 7040.3160. Selection rationale is based on:

• Product Status Alignment: The substitute is active production status, ensuring long-term availability and supply chain continuity
• Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status. The substitute carries expanded international certifications (CCC, cURus, KC, PSE/JET, VDE) versus the original part's UR approval, providing broader market acceptance
• Functional Equivalence: Identical current rating, response time, and physical dimensions ensure drop-in compatibility within existing circuit protection schemes
• Enhanced Capability: The substitute's higher voltage ratings (250V AC / 150V DC) and superior breaking capacity (1.5kA) provide margin for applications at or below the original part's 125V AC specification

Frequently Asked Questions (FAQ)

Q: Can the 0001.2511 be used as a direct replacement for the 7040.3160?

A: Yes. Both parts share identical current ratings (5A), response characteristics (slow-blow), and physical dimensions (5mm x 20mm). The substitute operates within the original part's voltage envelope and maintains compatible holder requirements.

Q: What is the primary difference between these two fuses?

A: The main differences are construction material (glass versus ceramic), voltage ratings (125V AC versus 250V AC / 150V DC), and product status (obsolete versus active). The ceramic construction of the substitute provides higher breaking capacity and broader temperature operating range.

Q: Are there any compatibility concerns when substituting?

A: No compatibility concerns exist for mechanical or electrical integration. Both fuses require identical holder assemblies and provide equivalent circuit protection at the 5A level. The substitute's higher voltage rating does not create incompatibility with 125V AC systems.

Q: What certifications does the substitute carry?

A: The 0001.2511 carries CCC, cURus, KC, PSE/JET, and VDE approvals, compared to the original part's UR approval. This expanded certification portfolio supports deployment across multiple international markets.

Q: Is the operating temperature range a consideration for substitution?

A: The substitute operates across -55°C to 125°C, compared to the original part's -40°C to 70°C range. This expanded range provides additional operational margin and does not restrict substitution in applications within the original temperature envelope.
