L090.653 Equivalent & Substitute Parts

Part Overview

The L090.653 is a 200 mA AC DC fuse cartridge manufactured by SCHURTER Inc. in a 5mm x 20mm glass form factor. This component is classified as obsolete and requires a holder for installation. Due to its obsolete product status, equivalent substitute parts are necessary to maintain system functionality and ensure continued availability for repair, maintenance, and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the L090.653 is based on the following critical parameters that must remain consistent:

• Current Rating: 200 mA (exact match required)
• Fuse Type: Cartridge, Glass (form factor compatibility)
• Package / Case: 5mm x 20mm (physical and holder compatibility)
• Response Time: Slow Blow (circuit protection characteristic)
• Mounting Type: Requires Holder (installation method)

The substitute part 0034.5036 satisfies all these core parameters while offering the advantage of active product status and enhanced electrical specifications including voltage rating and breaking capacity documentation.

Parameter Comparison

Engineering Selection Recommendations

The 0034.5036 serves as the direct substitute for the obsolete L090.653. Both components share identical current ratings, response characteristics, and physical form factors required for holder compatibility.

The 0034.5036 provides additional engineering advantages:

• Active Product Status: Ensures long-term availability and supply chain continuity
• Regulatory Compliance: Certified to cURus standards with ROHS3 compliance and REACH unaffected status
• Specified Electrical Parameters: Includes documented voltage rating (250 V AC), breaking capacity (35A), and thermal characteristics (-40°C ~ 85°C operating range)
• Defined Performance Metrics: Melting I²t value of 1.73 provides quantified thermal response data

The minor dimensional variation (0.205" Dia vs. 0.197" Dia and 5.20mm vs. 5.00mm) remains within standard holder tolerances for 5mm x 20mm cartridge fuses and does not affect functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 0034.5036 directly replace the L090.653 in existing applications?

A: Yes. Both components are 200 mA slow-blow glass cartridge fuses in 5mm x 20mm form factor requiring identical holders. The substitute maintains all critical electrical and mechanical parameters necessary for direct substitution.

Q: What is the significance of the voltage rating on the 0034.5036?

A: The 0034.5036 is rated for 250 V AC, which establishes the maximum voltage at which the fuse will operate within its specified breaking capacity of 35A. This parameter is documented on the substitute but not provided for the obsolete L090.653.

Q: Are there dimensional compatibility concerns between the two parts?

A: The 0034.5036 has a slightly larger diameter (0.205" vs. 0.197") and length dimension (5.20mm vs. 5.00mm). These variations fall within standard manufacturing tolerances for 5mm x 20mm cartridge fuses and are compatible with standard fuse holders designed for this form factor.

Q: What regulatory certifications apply to the substitute part?

A: The 0034.5036 holds cURus approval, is ROHS3 compliant, and is REACH unaffected. These certifications ensure compliance with North American and European regulatory requirements for electrical safety and environmental standards.

Q: Why is the L090.653 listed as obsolete?

A: The L090.653 is classified as obsolete, indicating it is no longer in active production. The 0034.5036 from the same manufacturer provides equivalent functionality with active product status and enhanced documentation of electrical specifications.
