SCHURTER 0001.1035 Equivalent & Substitute Parts

Part Overview

The SCHURTER 0001.1035 is a 12.5A 250VAC fast-blow glass cartridge fuse in 3AB/3AG package format (6.35mm × 31.80mm). This component is classified as obsolete, necessitating identification of active equivalent parts for ongoing system maintenance and new designs. The fuse requires a compatible holder for installation and operates across the temperature range of -40°C to 85°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCHURTER 0001.1035 is determined by the following critical parameters:

• Current Rating: 12.5 A (must match exactly)
• Physical Dimensions: 6.35mm × 31.80mm (must match for holder compatibility)
• Response Time: Fast Blow (must match for circuit protection characteristics)
• Operating Temperature Range: -40°C ~ 85°C (must match or exceed)
• Mounting Type: Requires Holder (must be compatible with existing installation)

The substitute part SCHURTER 8020.5079 satisfies these core substitution criteria. While the substitute offers enhanced voltage ratings (500VAC / 400VDC versus 250VAC) and higher breaking capacity (1.5kA versus 1kA), these represent functional improvements that do not compromise compatibility in applications rated for the original 250VAC specification.

Parameter Comparison

Engineering Selection Recommendations

The SCHURTER 8020.5079 is the designated substitute for the obsolete SCHURTER 0001.1035. Selection is based on the following engineering criteria:

• Both components maintain identical current ratings (12.5A) and physical dimensions (6.35mm × 31.80mm), ensuring mechanical and electrical compatibility within existing holder assemblies.
• Both components exhibit fast-blow response characteristics and operate across the identical temperature range (-40°C to 85°C).
• The substitute part carries active product status, ensuring ongoing availability and supply chain continuity.
• Both components achieve ROHS3 compliance and REACH unaffected status, meeting regulatory requirements.
• The substitute part carries cURus approval certification, providing additional third-party validation.
• The enhanced voltage rating (500VAC / 400VDC) and breaking capacity (1.5kA) of the substitute part provide functional margin in applications originally specified for 250VAC operation.

Frequently Asked Questions (FAQ)

Q: Can the SCHURTER 8020.5079 be used as a direct replacement for the 0001.1035 in 250VAC applications?

A: Yes. The substitute part is rated for 500VAC, which exceeds the original 250VAC requirement. The identical current rating (12.5A), physical dimensions (6.35mm × 31.80mm), and fast-blow response time ensure functional compatibility in the original application.

Q: What is the primary difference between the original and substitute parts?

A: The original 0001.1035 uses glass construction with 250VAC rating, while the substitute 8020.5079 uses ceramic construction with 500VAC / 400VDC ratings. Both maintain the same current rating, dimensions, and response characteristics.

Q: Are both parts compatible with the same holder assembly?

A: Yes. Both components share identical physical dimensions (0.250" diameter × 1.252" length) and require the same holder type. No mechanical modifications are necessary for installation.

Q: What certifications apply to the substitute part?

A: The SCHURTER 8020.5079 carries cURus approval certification, ROHS3 compliance, and REACH unaffected status. The original part does not specify approval agency certification.

Q: Is the substitute part available in the same packaging format?

A: The substitute part is supplied in bulk packaging, whereas the original part packaging format is not specified. Verify packaging requirements with your procurement process.
