LED Circuit Board Indicator 5513508 Equivalent & Substitute Parts

Part Overview

The Dialight 5513508 is a 3mm through-hole LED circuit board indicator featuring dual-color capability with green and red light output. This component is classified as obsolete, necessitating identification of active equivalent parts for ongoing design requirements and production continuity. The bicolor configuration with clear lens and right-angle mounting provides standard circuit board indicator functionality for applications requiring dual-state visual indication.

Key Parameters

Substitute Part Grouping Explanation

The Kingbright WP42WUM/EGW qualifies as a functional equivalent to the Dialight 5513508 based on the following critical parameters:

Mechanical Compatibility:

• Identical lens size: 3mm, T-1
• Identical lens style: Round with Domed Top
• Identical mounting type: Through Hole, Right Angle
• Identical color configuration: Green, Red dual-color

Electrical Compatibility:

• Voltage ratings within acceptable tolerance: 2.2V Green vs. 2.1V Green (0.1V variance); 2V Red matches exactly
• Current ratings compatible with standard circuit design: 25mA Green, 30mA Red vs. 20mA single rating
• Wavelength peaks within visible spectrum tolerance: 565nm Green vs. 560nm Green; 627nm Red vs. 630nm Red

Regulatory & Compliance Alignment:

• Identical MSL rating: 1 (Unlimited)
• Identical REACH status: REACH Unaffected
• Identical ECCN classification: EAR99
• Identical HTSUS code: 8541.41.0000

Key Difference - Lens Characteristic: The substitute features a diffused lens with white coating versus the clear lens of the original. This represents the primary functional distinction and must be evaluated against application requirements for light diffusion and intensity distribution.

Parameter Comparison

Engineering Selection Recommendations

The Kingbright WP42WUM/EGW is an active product with ROHS3 compliance, providing supply continuity for the obsolete Dialight 5513508. Both components share identical mechanical form factors, mounting configurations, and regulatory classifications.

The substitute exhibits higher luminous intensity (12mcd green, 8mcd red versus 4mcd for the original) and operates at marginally higher voltage for the green element (2.2V versus 2.1V). The diffused lens characteristic alters light distribution compared to the clear lens original, resulting in a narrower viewing angle (100° versus 116°).

Selection of the WP42WUM/EGW requires confirmation that the increased brightness and diffused light output are compatible with the target application's optical and electrical design parameters.

Frequently Asked Questions (FAQ)

Q: Can the Kingbright WP42WUM/EGW be used as a direct drop-in replacement for the Dialight 5513508?

A: Mechanical and electrical compatibility exists for through-hole circuit board mounting. The primary consideration is the lens characteristic change from clear to diffused, which affects light distribution and intensity perception. Circuit design must accommodate the higher current ratings (25mA green, 30mA red) and the 0.1V increase in green voltage.

Q: What is the impact of the diffused lens versus clear lens?

A: The diffused lens with white coating provides broader light scattering but reduces peak intensity in the direct viewing direction. The viewing angle decreases from 116° to 100°. Applications requiring focused light output or specific intensity profiles must evaluate this change.

Q: Are there packaging differences between these components?

A: The Dialight 5513508 packaging is specified as "-" (not detailed). The Kingbright WP42WUM/EGW is supplied in bulk packaging. Procurement and handling procedures may differ accordingly.

Q: Do both components meet the same regulatory requirements?

A: Both components share identical REACH status (REACH Unaffected), ECCN classification (EAR99), and HTSUS codes (8541.41.0000). The Kingbright component includes ROHS3 compliance certification, which is not specified for the obsolete Dialight part.

Q: What are the wavelength differences?

A: Green wavelength differs by 5nm (565nm versus 560nm). Red wavelength differs by 3nm (627nm versus 630nm). Both variations remain within standard visible spectrum tolerances for dual-color indicator applications.

Q: How do the current ratings affect circuit design?

A: The Dialight 5513508 operates at a uniform 20mA. The Kingbright WP42WUM/EGW requires 25mA for green and 30mA for red operation. Current-limiting resistor values must be recalculated based on the supply voltage and these higher current specifications.
