Key Parameters

Substitute Part Grouping Explanation

Substitution for the SCHURTER 0001.1022 is determined by the following critical parameters:

• Current Rating: 630 mA (exact match required)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (physical and electrical compatibility)
• Response Time: Fast Blow (functional characteristic)
• Breaking Capacity: 1.5 kA @ Rated Voltage (fault protection capability)
• Operating Temperature Range: -40°C to 85°C (environmental compatibility)
• Mounting Type: Requires Holder (installation method)

The substitute part SCHURTER 8020.5066 meets all critical substitution criteria. While it features a ceramic construction instead of glass and supports higher voltage ratings (500 V AC/DC versus 250 V AC), these enhancements provide superior performance characteristics within the same physical package and current rating. The ceramic fuse maintains identical breaking capacity, response time classification, and temperature operating range.

Parameter Comparison

Engineering Selection Recommendations

The SCHURTER 8020.5066 is the direct substitute for the obsolete SCHURTER 0001.1022. Both components are ROHS3 compliant and REACH unaffected, meeting current environmental regulations. The substitute part carries active product status with cURus approval certification, ensuring ongoing availability and regulatory support.

The ceramic construction of the 8020.5066 provides enhanced voltage handling capability (500 V AC/DC) compared to the glass fuse (250 V AC), making it suitable for applications requiring higher voltage margins or mixed AC/DC circuit environments. The identical current rating, package dimensions, breaking capacity, and response time classification ensure direct functional compatibility within existing holder assemblies.

Frequently Asked Questions (FAQ)

Q: Can the SCHURTER 8020.5066 be used as a direct replacement for the 0001.1022?

A: Yes. Both fuses share identical current ratings (630 mA), package dimensions (3AB, 3AG, 1/4" x 1-1/4"), breaking capacity (1.5 kA), response time (fast blow), and operating temperature range (-40°C to 85°C). The substitute is physically and electrically compatible with existing 0001.1022 holder assemblies.

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

A: The main differences are material construction and voltage rating. The 0001.1022 is a glass fuse rated for 250 V AC, while the 8020.5066 is a ceramic fuse rated for 500 V AC and 500 V DC. The ceramic construction provides higher voltage capability and improved performance characteristics.

Q: Are both fuses compliant with current environmental standards?

A: Yes. Both the 0001.1022 and 8020.5066 are ROHS3 compliant and REACH unaffected. The 8020.5066 additionally carries cURus approval certification.

Q: Why is the 0001.1022 listed as obsolete?

A: The 0001.1022 is classified as obsolete, indicating it is no longer in active production. The SCHURTER 8020.5066 represents the current active alternative for this application category.

Q: Will the higher voltage rating of the 8020.5066 affect circuit operation?

A: No. The 8020.5066 is rated for higher voltage (500 V AC/DC) than the original specification (250 V AC). This provides additional safety margin and does not negatively impact circuits designed for the lower voltage rating. The fuse will operate identically at the original circuit voltage.

Q: Are the physical dimensions identical?

A: Yes. Both fuses measure 0.250" diameter x 1.252" length (6.35 mm x 31.80 mm) and use the same 3AB/3AG package format, ensuring compatibility with existing holder assemblies without modification.
