SSL-LX3059GYW Equivalent & Substitute Parts

Part Overview

The SSL-LX3059GYW is a dual-color LED indicator manufactured by Lumex Opto/Components Inc., featuring integrated green and yellow light-emitting elements in a single 3mm through-hole package. This common cathode configuration provides green and yellow indication capability with diffused lens optics. The component is classified as Active product status with full RoHS3 compliance and REACH unaffected designation. Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and regulatory compliance can be maintained across alternative manufacturers while preserving the core functional requirements of dual-color LED indication in T-1 form factor applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SSL-LX3059GYW are qualified based on the following substitution criteria:

Electrical Compatibility Parameters:

• Dual-color green and yellow LED configuration
• Common cathode circuit topology
• Forward voltage range: Green 2.2V ±0.1V, Yellow 2.0-2.1V
• Test current specification: 20mA for both colors
• Viewing angle: 60° minimum

Mechanical Compatibility Parameters:

• Through-hole mounting type
• 3-lead radial package configuration
• 3mm lens diameter (T-1 form factor)
• Diffused lens transparency
• Maximum height within 7.83mm

Regulatory & Compliance Parameters:

• RoHS3 Compliant status
• REACH Unaffected designation
• Active product status

The substitute parts WP115VGYW and WP115WGYW from Kingbright meet all electrical and mechanical compatibility requirements while maintaining full regulatory compliance. Both alternatives operate within the specified voltage and current parameters, utilize identical package geometry, and provide equivalent through-hole mounting characteristics.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criteria:

Both WP115VGYW and WP115WGYW qualify as direct substitutes for SSL-LX3059GYW based on maintained electrical compatibility and mechanical interchangeability. Selection between alternatives depends on luminous intensity requirements:

WP115VGYW Selection: This substitute provides 30mcd green and 24mcd yellow output, representing a 5x increase in green luminous intensity and 4x increase in yellow intensity compared to the SSL-LX3059GYW. This configuration suits applications requiring enhanced visibility or greater viewing distance performance while maintaining identical forward voltage characteristics and 20mA test current specification.

WP115WGYW Selection: This substitute provides 40mcd green and 20mcd yellow output, delivering maximum green luminous intensity at 6.7x the original specification. Yellow output at 20mcd represents 3.3x the original rating. This configuration addresses applications with the highest visibility requirements for green indication while maintaining balanced yellow performance.

Regulatory Compliance: All three components maintain Active product status, ROHS3 compliance, and REACH unaffected designation. No compliance barriers exist for substitution in regulated applications.

Mechanical Compatibility: All parts utilize identical through-hole mounting, 3-lead radial package configuration, and 3mm T-1 lens form factor. Height variation (7.03mm original vs. 7.83mm substitutes) represents 0.8mm maximum difference and does not impact standard PCB layout or enclosure clearance in typical applications.

Frequently Asked Questions (FAQ)

Q: Can WP115VGYW and WP115WGYW be used interchangeably with SSL-LX3059GYW in existing circuit designs?

A: Yes. Both Kingbright substitutes maintain identical forward voltage specifications (2.2V green, 2.1V yellow) and test current (20mA). The common cathode configuration and 3-lead radial package provide direct pin-for-pin compatibility. Circuit designs do not require modification for electrical substitution.

Q: What is the primary difference between WP115VGYW and WP115WGYW?

A: The primary difference is luminous intensity. WP115VGYW provides 30mcd green and 24mcd yellow. WP115WGYW provides 40mcd green and 20mcd yellow. Both maintain identical electrical parameters and mechanical form factor. Selection depends on whether green or balanced intensity is prioritized for the application.

Q: Does the 0.8mm height difference between SSL-LX3059GYW (7.03mm) and the Kingbright substitutes (7.83mm) create compatibility issues?

A: No. The 0.8mm height variation falls within standard PCB layout tolerances and does not impact through-hole mounting, enclosure clearance, or viewing angle performance in typical indicator applications. Both substitute parts maintain the same 60° viewing angle and diffused lens characteristics.

Q: Are forward voltage differences between SSL-LX3059GYW (2.0V yellow) and substitutes (2.1V yellow) significant?

A: No. The 0.1V difference in yellow forward voltage is within standard LED manufacturing tolerance and does not require circuit redesign. Current-limiting resistor calculations remain valid across all three parts when using standard design margins.

Q: What inventory considerations apply to these substitutes?

A: SSL-LX3059GYW maintains 1156 pieces in stock. WP115VGYW provides 3091 pieces in stock. WP115WGYW provides 29999 pieces in stock. Kingbright substitutes offer significantly higher availability for applications requiring volume procurement or extended supply chain security.

Q: Do all three parts maintain identical compliance certifications?

A: Yes. SSL-LX3059GYW, WP115VGYW, and WP115WGYW all carry ROHS3 Compliant status and REACH Unaffected designation. No compliance barriers exist for substitution in regulated markets or applications requiring environmental compliance documentation.
