Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5520833F is determined by the following critical parameters:

• Color specification: Yellow (x 2) dual-level configuration
• Wavelength consistency: 585nm peak wavelength
• Mounting interface: Through-hole, right-angle orientation
• Lens characteristics: Diffused, tinted optical properties
• Viewing angle: 50° minimum specification
• Series compatibility: Dialight 552 series platform
• Regulatory compliance: ROHS3 and REACH status alignment

The Dialight 5520233F satisfies these substitution criteria while operating within acceptable electrical parameter variations for the dual-level indicator application category.

Parameter Comparison

Engineering Selection Recommendations

The 5520233F serves as the manufacturer-designated substitute for the obsolete 5520833F. Both components maintain identical series designation, color specification, wavelength output, viewing angle, and mounting configuration within the Dialight 552 platform.

The substitute part operates at reduced electrical parameters: 2.1V versus 2.2V and 10mA versus 20mA, resulting in lower luminous intensity (6.3mcd versus 34mcd). Circuit design modifications may be required to accommodate these electrical differences.

Both parts maintain equivalent regulatory compliance status: ROHS3 certification and REACH unaffected classification. The substitute part carries active product status, ensuring long-term availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the 5520233F directly replace the 5520833F without circuit modification?

A: Mechanical and optical compatibility is maintained through identical mounting type, lens characteristics, and viewing angle. Electrical circuit verification is required due to voltage and current specification differences.

Q: What are the key differences between these parts?

A: The substitute operates at lower voltage (2.1V vs 2.2V) and current (10mA vs 20mA) ratings, resulting in reduced brightness output (6.3mcd vs 34mcd). Mounting and optical properties remain equivalent.

Q: Are both parts compliant with current regulatory requirements?

A: Both the main part and substitute maintain ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory standards.

Q: What is the significance of the lens style difference?

A: The substitute features a round domed top lens in 5mm T-1 3/4 configuration, compared to the main part's unspecified lens style. Both maintain diffused, tinted optical properties and 50° viewing angle.

Q: Why is the main part classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The 5520233F represents the active product line continuation within the same series platform.
