SSL-LX2573GD-TR Equivalent & Substitute Parts

Part Overview

The SSL-LX2573GD-TR is an active green LED indication component manufactured by Lumex Opto/Components Inc., designed for through-hole mounting applications. This discrete 2.2V radial LED operates at 20mA test current and delivers 6mcd luminous intensity with a diffused lens for uniform light distribution. The component is ROHS3 compliant and REACH unaffected, making it suitable for regulated electronic assemblies. Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and compliance certifications are maintained across alternative manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SSL-LX2573GD-TR are identified based on strict equivalence across the following parameters:

Electrical Equivalence Requirements:

• Forward voltage (Vf) of 2.2V typical
• Test current of 20mA
• Green color specification
• Peak wavelength in the 565nm range (green spectrum)

Mechanical Equivalence Requirements:

• Through-hole radial mounting configuration
• Maximum height of 7.00mm
• Diffused lens transparency for uniform light distribution
• Viewing angle of 110°

Compliance Equivalence Requirements:

• ROHS3 compliance status
• REACH unaffected status
• EAR99 ECCN classification
• HTSUS code 8541.41.0000

The WP113GDT from Kingbright satisfies all critical substitution criteria and is classified as a direct equivalent for circuit and assembly applications.

Engineering Selection Recommendations

SSL-LX2573GD-TR Selection Criteria:

• Primary choice when original Lumex component is specified in design documentation
• Preferred for applications requiring the 3.00mm x 2.00mm lens form factor
• 745 pieces currently in stock for immediate availability

WP113GDT Selection Criteria:

• Direct substitute when Lumex SSL-LX2573GD-TR is unavailable or discontinued
• Suitable for applications where the 5.00mm x 2.00mm rectangular lens form factor is acceptable
• Maintains identical electrical performance: 2.2V forward voltage, 20mA test current, 110° viewing angle
• Delivers equivalent luminous intensity (5mcd vs. 6mcd) within acceptable tolerance for indication applications
• Meets all regulatory requirements: ROHS3 compliant, REACH unaffected, EAR99 classification
• 36,063 pieces in stock provide extended supply availability
• Radial through-hole package ensures PCB assembly compatibility without modification

Both components are active products with confirmed compliance certifications and are suitable for direct substitution in green LED indication circuits operating at 2.2V nominal forward voltage.

Frequently Asked Questions (FAQ)

Q: Can WP113GDT replace SSL-LX2573GD-TR in existing PCB designs?

A: Yes, WP113GDT is a direct electrical and mechanical substitute. Both components feature identical forward voltage (2.2V), test current (20mA), viewing angle (110°), and radial through-hole mounting. The primary difference is lens size: SSL-LX2573GD-TR uses a 3.00mm x 2.00mm lens, while WP113GDT uses a 5.00mm x 2.00mm rectangular lens. PCB layout must accommodate the larger lens footprint.

Q: Are there luminous intensity differences between these parts?

A: SSL-LX2573GD-TR is rated at 6mcd, while WP113GDT is rated at 5mcd. This 1mcd difference is within acceptable tolerance for standard LED indication applications and does not affect circuit functionality or compliance.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both SSL-LX2573GD-TR and WP113GDT are ROHS3 compliant, REACH unaffected, classified as EAR99, and share the same HTSUS code (8541.41.0000). They are equivalent for regulated assembly environments.

Q: What is the viewing angle specification, and does it affect substitution?

A: Both components specify 110° viewing angle, which defines the cone of light distribution from the LED. This parameter is identical across both parts and does not impact substitution compatibility.

Q: Are there packaging or moisture sensitivity differences?

A: SSL-LX2573GD-TR packaging is listed as "-" (not specified in available data). WP113GDT is supplied in bulk packaging with MSL 1 (Unlimited) moisture sensitivity level, indicating no moisture-related storage restrictions. Both are through-hole components with minimal moisture sensitivity concerns.

Q: What is the wavelength specification, and why is it important?

A: Both components specify 565nm peak wavelength, which defines the green spectrum. This parameter is critical for color matching in indication applications and is identical between the two parts.

Q: Can these parts be used interchangeably in high-volume production?

A: Yes, provided PCB layout accommodates the 5.00mm x 2.00mm lens size of WP113GDT. Circuit design, forward voltage, current limiting, and assembly processes remain unchanged. Both parts are active products with confirmed stock availability.
