SSL-LX30S54GD Green LED T-1 Through Hole Equivalent & Substitute Parts

Part Overview

The SSL-LX30S54GD is an active green LED indication component manufactured by Lumex Opto/Components Inc. This discrete 3mm T-1 through-hole LED operates at 2.2V forward voltage with a 20mA test current and delivers 20 millicandela brightness with a 60° viewing angle. The component features a diffused green lens with a round domed top and is housed in a radial package configuration. Current inventory status shows 966 pieces in stock as new original components.

Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part specifications, enabling direct replacement in circuit designs without functional degradation.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SSL-LX30S54GD are identified based on strict alignment of the following critical parameters:

Electrical Parameters:

• Forward voltage (Vf): 2.2V
• Test current: 20mA
• Millicandela rating: 20mcd

Mechanical Parameters:

• Lens size: 3mm, T-1
• Lens color: Green
• Lens transparency: Diffused
• Mounting type: Through hole
• Package configuration: Radial

Compliance Parameters:

• RoHS3 compliance
• REACH unaffected status
• Moisture sensitivity level: 1 (Unlimited)

Substitute parts are grouped into two categories: parametric equivalents from the same manufacturer and direct manufacturer alternatives. Parametric equivalents maintain identical electrical specifications and core mechanical dimensions. Direct manufacturer alternatives from different suppliers meet the same functional requirements within specified tolerances.

Parameter Comparison

Engineering Selection Recommendations

SSL-LX3044PGD (Parametric Equivalent - Lumex Opto/Components Inc.)

This substitute maintains identical electrical specifications and core mechanical dimensions as the SSL-LX30S54GD. Both components are manufactured by Lumex Opto/Components Inc., ensuring consistent design philosophy and quality standards. The SSL-LX3044PGD operates at the same 2.2V forward voltage and 20mA test current with identical 20mcd brightness output. The maximum height differential of 0.40mm (4.60mm versus 5.00mm) falls within standard PCB layout tolerances for through-hole components. Peak wavelength differs by 10nm (555nm versus 565nm), remaining within the green spectrum range. Both components carry ROHS3 compliance and unlimited moisture sensitivity rating. Significantly higher inventory availability (114655 pieces) supports supply chain continuity.

WP3A8GD (Direct Alternative - Kingbright)

This substitute from Kingbright meets all critical electrical parameters: 2.2V forward voltage, 20mA test current, and 20mcd brightness output. The component shares identical 3mm T-1 through-hole radial package configuration and diffused green lens specification. Physical dimensions align with the main part (5.00mm maximum height). Peak wavelength matches at 565nm. The viewing angle specification differs at 50° compared to 60°, representing a narrower field of view. ROHS3 compliance and unlimited moisture sensitivity rating match the main part. Inventory availability of 29255 pieces provides alternative sourcing.

All substitute parts maintain active product status and full regulatory compliance with ROHS3 and REACH requirements.

Frequently Asked Questions (FAQ)

Q: Can SSL-LX3044PGD replace SSL-LX30S54GD in all applications?

A: SSL-LX3044PGD is a parametric equivalent with identical electrical specifications (2.2V, 20mA, 20mcd). The 0.40mm height difference and 10nm wavelength variation fall within standard component tolerances for green LED indication circuits. Both components are manufactured by Lumex and carry identical compliance certifications.

Q: What is the difference in viewing angle between the main part and WP3A8GD?

A: The SSL-LX30S54GD specifies a 60° viewing angle, while WP3A8GD specifies 50°. This represents a narrower field of view with the Kingbright component. Applications requiring wide-angle visibility should account for this specification difference.

Q: Are all substitute parts through-hole mounted?

A: Yes. The SSL-LX30S54GD, SSL-LX3044PGD, and WP3A8GD all feature through-hole radial mounting in T-1 package configuration, enabling direct PCB footprint compatibility.

Q: Do all parts meet RoHS3 compliance?

A: Yes. The main part SSL-LX30S54GD and both substitute parts (SSL-LX3044PGD and WP3A8GD) are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Q: What is the wavelength specification difference between substitutes?

A: SSL-LX30S54GD and WP3A8GD both specify 565nm peak wavelength. SSL-LX3044PGD specifies 555nm peak wavelength. Both wavelengths fall within the green spectrum and are suitable for standard green LED indication applications.

Q: Which substitute offers the best inventory availability?

A: SSL-LX3044PGD provides the highest inventory availability at 114655 pieces, compared to 29255 pieces for WP3A8GD and 966 pieces for the main part SSL-LX30S54GD.

Q: Can WP3A8GD be used as a direct drop-in replacement?

A: WP3A8GD meets all critical electrical and mechanical specifications for direct replacement. The 50° viewing angle specification should be evaluated against application requirements. All compliance certifications align with the main part.
