Key Parameters

Substitute Part Grouping Explanation

Substitution of the B090.667 is based on the following critical parameters that must remain consistent:

• Current Rating: 5 A (exact match required)
• Package Dimensions: 5mm x 20mm (physical compatibility with existing holders)
• Response Time: Slow Blow (circuit protection characteristic)
• Mounting Configuration: Requires Holder (installation method)

The primary substitute, SCHURTER 0001.2511, maintains all four critical parameters while transitioning from glass to ceramic fuse construction. This material change does not affect functional compatibility within the 5mm x 20mm holder form factor. The ceramic variant introduces additional electrical ratings (250 V AC, 150 V DC) and enhanced operational specifications including temperature range (-55°C to 125°C) and breaking capacity (1.5 kA), making it suitable for broader application requirements.

Parameter Comparison

Engineering Selection Recommendations

The SCHURTER 0001.2511 serves as the direct functional equivalent for the obsolete B090.667. Both components share identical current ratings, response characteristics, and physical form factors required for 5mm x 20mm holder compatibility.

The 0001.2511 is classified as an active product with current manufacturing status, ensuring long-term availability and supply chain continuity. This substitute incorporates ceramic construction with specified voltage ratings (250 V AC, 150 V DC), breaking capacity (1.5 kA), and an extended operating temperature range (-55°C to 125°C). The part carries multiple international approvals including CCC, cURus, KC, PSE/JET, and VDE certifications, and meets ROHS3 compliance requirements.

Selection of the 0001.2511 eliminates obsolescence risk while maintaining electrical and mechanical compatibility with existing circuit designs utilizing 5mm x 20mm fuse holders.

Frequently Asked Questions (FAQ)

Q: Can the SCHURTER 0001.2511 be used as a direct replacement for the B090.667?
