SCHURTER 7040.3200 Equivalent & Substitute Parts

Part Overview

The SCHURTER 7040.3200 is a 12.5 A, 32 V AC/DC glass cartridge fuse in a 5mm x 20mm package format. This fuse is designed for applications requiring slow-blow response characteristics and operates across a temperature range of -40°C to 70°C. The part is classified as obsolete, necessitating identification of functionally compatible alternatives for ongoing system support and new designs. Substitute parts must maintain the same current rating, package dimensions, and mounting requirements while accommodating updated voltage specifications and material compositions.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCHURTER 7040.3200 is based on the following critical parameters that must remain constant or be exceeded:

Fixed Parameters (Must Match):

• Current Rating: 12.5 A
• Package Dimensions: 5mm x 20mm
• Mounting Type: Requires Holder
• Response Time: Slow Blow

Allowable Parameter Variations:

• Fuse Material: Glass to Ceramic (material upgrade permitted)
• Voltage Rating: 32 V AC to higher voltage ratings (upward compatibility)
• Breaking Capacity: 100 A to higher values (increased capacity acceptable)
• Operating Temperature: -40°C to 70°C to wider ranges (extended range acceptable)
• Product Status: Obsolete to Active (active status preferred for availability)

The substitute part SCHURTER 0001.2515 maintains all fixed parameters while providing enhanced voltage ratings, improved breaking capacity, extended temperature range, and active product status.

Parameter Comparison

Engineering Selection Recommendations

The SCHURTER 0001.2515 serves as a direct functional substitute for the obsolete SCHURTER 7040.3200 based on the following engineering criteria:

Current Rating Compatibility: Both parts are rated for 12.5 A, ensuring identical load-carrying capacity.

Package Compatibility: Both parts utilize the 5mm x 20mm cartridge format with holder-based mounting, enabling direct mechanical installation in existing fuse holders.

Response Characteristics: Both parts provide slow-blow response, maintaining circuit protection behavior consistent with the original design.

Voltage Capability: The substitute part operates at 250 V AC and 125 V DC, exceeding the original 32 V AC specification. This upward voltage rating ensures compatibility with the original application while providing margin for higher-voltage system implementations.

Regulatory Compliance: The substitute part carries cURus, PSE/JET, and VDE approvals, along with ROHS3 compliance and REACH unaffected status. The original part provides no specified approvals, making the substitute superior for regulated applications.

Product Availability: The substitute part maintains active product status with 4,686 units in stock, compared to the obsolete status of the original part with 933 units remaining.

Material Enhancement: The ceramic construction of the substitute part provides improved thermal stability and breaking capacity (500 A AC, 1.5 kA DC) compared to the glass construction of the original part (100 A).

Frequently Asked Questions (FAQ)

Q: Can the SCHURTER 0001.2515 be used as a direct replacement for the 7040.3200 in existing applications?

A: Yes. Both parts share identical current ratings (12.5 A), package dimensions (5mm x 20mm), response characteristics (slow blow), and mounting requirements (holder-based). The substitute part's higher voltage rating (250 V AC, 125 V DC) is compatible with applications originally designed for 32 V AC operation.

Q: What is the difference between glass and ceramic fuse construction?

A: The 7040.3200 uses glass construction, while the 0001.2515 uses ceramic construction. Ceramic fuses provide higher breaking capacity, improved thermal stability, and extended operating temperature ranges. Both materials are suitable for cartridge fuse applications in the 5mm x 20mm format.

Q: Does the substitute part fit in the same fuse holder as the original?

A: Yes. Both parts are 5mm x 20mm cartridge fuses requiring a compatible holder. The substitute part dimensions (0.205" Dia x 0.787" L) are mechanically compatible with holders designed for the original part (0.197" Dia x 0.787" L).

Q: Why does the substitute part have a lower melting I²t value (563 vs. 890)?

A: The melting I²t value reflects the thermal energy required to melt the fuse element. The lower value in the ceramic substitute part (0001.2515) indicates faster thermal response while maintaining the same 12.5 A current rating. This is a characteristic of ceramic fuse technology and does not affect compatibility in slow-blow applications.

Q: What regulatory approvals does the substitute part carry?

A: The SCHURTER 0001.2515 carries cURus, PSE/JET, and VDE approvals. It is ROHS3 compliant and REACH unaffected. The original part provides no specified approvals.

Q: Is the substitute part suitable for both AC and DC applications?

A: Yes. The substitute part is rated for 250 V AC and 125 V DC operation. The original part specification indicates 32 V AC with no DC rating specified. Applications requiring DC operation benefit from the explicit 125 V DC rating of the substitute part.

Q: What is the inventory status of each part?

A: The original SCHURTER 7040.3200 has 933 units in stock but is classified as obsolete. The substitute SCHURTER 0001.2515 has 4,686 units in stock and maintains active product status, ensuring long-term availability.
