Substitute Part Grouping Explanation

Substitute parts for the Dialight 5530128 are qualified based on strict electrical and mechanical parameter matching within the 553 series product family. The following parameters determine substitution eligibility:

Critical Matching Parameters:

• Dual-level configuration (2 High)
• Identical color combination: Blue (x 1), Green (x 1)
• Matching wavelength specifications: 428nm (Blue), 563nm (Green)
• Equivalent luminous intensity: 13.15mcd (Blue), 16mcd (Green)
• Identical voltage ratings: 4.6V (Blue), 2.1V (Green)
• Matching mechanical form factor: 3mm T-1 lens, round domed top
• Through-hole right-angle mounting configuration
• Equivalent environmental compliance: MSL 1, REACH Unaffected, EAR99

The substitute parts 5530128F and 5530182F maintain full electrical and mechanical compatibility with the original 5530128 specification.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts 5530128F and 5530182F are qualified direct replacements for the obsolete 5530128. Selection between these active alternatives should be based on the following factors:

Product Status: The 5530128 is classified as obsolete. Both 5530128F and 5530182F maintain active product status, ensuring long-term availability and supply chain continuity.

Compliance Certifications: Both substitute parts carry ROHS3 compliance certification, providing enhanced environmental regulatory alignment compared to the original part specification. Both maintain REACH Unaffected status and EAR99 export classification consistent with the main part.

Electrical and Mechanical Compatibility: All three part numbers maintain identical electrical specifications (voltage ratings, wavelength, luminous intensity) and mechanical form factors (3mm T-1 through-hole right-angle configuration). Direct circuit board substitution is supported without design modification.

Packaging Consideration: Both substitute parts are supplied in bulk packaging, which may differ from original packaging specifications for the 5530128.

Frequently Asked Questions (FAQ)

Q: Can 5530128F and 5530182F be used interchangeably with 5530128?

A: Yes. Both substitute parts maintain identical electrical specifications (voltage ratings, wavelength, luminous intensity) and mechanical form factors (3mm T-1 through-hole right-angle mounting). Direct circuit board substitution is supported without design modification.

Q: What is the primary reason for substitution?

A: The 5530128 is classified as obsolete. The substitute parts 5530128F and 5530182F are active products, ensuring continued availability and supply chain support.

Q: Are there differences in environmental compliance between the main part and substitutes?
