Part Overview

The SSL-LX3054HD is a red diffused T-1 through-hole LED manufactured by Lumex Opto/Components Inc., designed for red LED indication applications with discrete 2V radial configuration. This part is classified as obsolete, which necessitates identification of equivalent and substitute components for ongoing design requirements and production continuity. The SSL-LX3054HD features a 3mcd millicandela rating, 700nm peak wavelength, and 60° viewing angle in a standard 3mm T-1 package format.

Substitute Part Grouping Explanation

Substitution of the SSL-LX3054HD is determined by the following critical parameters: color (red), lens transparency (diffused), lens size (3mm T-1), mounting type (through hole), package type (radial), forward voltage range (1.7V to 2.1V), test current (10mA to 20mA), and compliance certifications (ROHS3, REACH Unaffected). Substitute parts are grouped into two categories:

Category 1: Manufacturer Recommended Substitute The SSL-LX3054ID from Lumex Opto/Components Inc. is the direct manufacturer-recommended replacement. This part maintains identical mechanical and electrical compatibility while offering improved brightness (40mcd versus 3mcd) and different wavelength characteristics (635nm versus 700nm).

Category 2: Similar Manufacturer Substitutes Alternative parts from Everlight Electronics Co Ltd, Bivar Inc., Visual Communications Company (VCC), and Broadcom Limited meet the core substitution criteria of red diffused 3mm T-1 through-hole configuration. These parts vary in forward voltage (1.7V to 5V), millicandela rating (1.8mcd to 400mcd), viewing angle (30° to 60°), and wavelength characteristics (625nm to 700nm). Selection depends on specific circuit requirements for brightness, voltage compatibility, and viewing angle specifications.

Engineering Selection Recommendations

Primary Recommendation: SSL-LX3054ID The SSL-LX3054ID is the manufacturer-recommended direct substitute for the obsolete SSL-LX3054HD. Both parts are manufactured by Lumex Opto/Components Inc. and share identical mechanical dimensions (5.25mm height), lens size (3mm T-1), forward voltage (2V), test current (20mA), viewing angle (60°), and mounting configuration (through-hole radial). The SSL-LX3054ID is currently in active production status with 28,630 units in stock. Both parts maintain ROHS3 compliance and MSL 1 rating. The primary difference is increased brightness (40mcd versus 3mcd) and wavelength shift (635nm versus 700nm). This part is suitable for direct replacement in existing designs.

Secondary Recommendations for Specific Requirements

For applications requiring lower forward voltage (1.7V) with maintained brightness (40mcd), the Bivar 3SRD-F or 3SRD-S parts are suitable. The 3SRD-S variant offers a reduced height of 4.50mm compared to the standard 5.30mm, accommodating space-constrained designs. Both maintain ROHS3 compliance and MSL 1 rating.

For applications requiring higher brightness (400mcd), the Everlight 1254-10SURD/S530-A3 provides significantly increased luminous intensity with 2V forward voltage and 20mA test current. This part is supplied in Tape & Reel packaging and maintains the 3mm T-1 form factor. Note that this part has a narrower viewing angle (30° versus 60°).

For applications with 5V supply voltage requirements, the Broadcom HLMP-1600 or HLMP-1600-D00A1 are suitable. The HLMP-1600-D00A1 variant includes right-angle mounting configuration for circuit board indicator applications. Both parts operate at 10mA test current and maintain 60° viewing angle with ROHS3 compliance.

Parts with "Not For New Designs" status (VCC 4300F1LC) should not be selected for new product development.

Frequently Asked Questions (FAQ)

Q: Can the SSL-LX3054ID directly replace the SSL-LX3054HD without circuit modification?

A: Yes. The SSL-LX3054ID maintains identical forward voltage (2V), test current (20mA), mechanical dimensions (5.25mm height), lens size (3mm T-1), and mounting type (through-hole radial). The primary difference is increased brightness (40mcd versus 3mcd), which does not require circuit modification. Both parts are ROHS3 compliant with MSL 1 rating.

Q: What are the key differences between the Bivar 3SRD-F and 3SRD-S variants?

A: Both parts share identical electrical specifications: 1.7V forward voltage, 20mA test current, 40mcd brightness, and 645nm wavelength. The primary difference is physical height: 3SRD-F is 5.30mm maximum height, while 3SRD-S is 4.50mm maximum height. The 3SRD-S also has a slightly wider viewing angle (40° versus 35°). Selection depends on available PCB space.

Q: Why does the Everlight 1254-10SURD/S530-A3 have a narrower viewing angle (30°) compared to the SSL-LX3054HD (60°)?

A: The Everlight part is designed for applications requiring higher brightness concentration (400mcd versus 3mcd). The narrower 30° viewing angle is a characteristic of higher-brightness LED designs that concentrate light output in a more focused beam pattern. This part is suitable only for applications where the narrower viewing angle is acceptable.

Q: Can I use the Broadcom HLMP-1600 in a 2V circuit designed for the SSL-LX3054HD?

A: No. The HLMP-1600 requires 5V forward voltage, which is incompatible with 2V circuits. Circuit redesign would be required to accommodate the higher voltage requirement. The HLMP-1600 is suitable only for applications with 5V supply availability.

Q: What is the significance of the "Not For New Designs" status on the VCC 4300F1LC?

A: Parts designated "Not For New Designs" are in declining production and should not be selected for new product development. These parts are available for legacy system support only. For new designs, select from parts with "Active" product status.

Q: Are all substitute parts ROHS3 compliant?

A: All recommended substitute parts listed with specified compliance status are ROHS3 compliant. The Everlight 1254-10SURD/S530-A3 does not specify RoHS status in the provided data and should be verified with the manufacturer before selection for RoHS-regulated applications.

Q: What packaging options are available for the substitute parts?

A: The SSL-LX3054ID is supplied in Bulk packaging. The Everlight 1254-10SURD/S530-A3 is supplied in Tape & Reel (TR) format. Bivar parts (3HD-F, 3RD-F, 3SRD-F, 3SRD-S) are supplied in Bulk packaging. Broadcom parts (HLMP-1301-G00FG, HLMP-1600, HLMP-1600-D00A1) are supplied in Bulk packaging. VCC 4300F1LC is supplied in Bulk packaging. Packaging selection affects procurement and assembly processes.

Q: How do wavelength differences (700nm versus 635nm) affect visual appearance?

A: The SSL-LX3054HD operates at 700nm (deep red), while most substitute parts operate at 625nm to 645nm (standard red). The 700nm wavelength produces a darker, more orange-tinted red appearance compared to the brighter, more pure red of 635nm parts. Selection depends on visual appearance requirements for the application.
