Engineering Selection Recommendations

Primary Substitutes (Highest Compatibility):

The HLMP-3351 series from Broadcom Limited represents the most direct substitutes for the SSL-LX5093BHD. These components maintain the T-1 3/4 form factor, diffused red lens, and through-hole mounting configuration. The HLMP-3351, HLMP-3351-D0000, HLMP-3351-D0002, and HLMP-3351-F00R1 variants are all active products with ROHS3 compliance and MSL 1 rating. The primary electrical difference is the forward voltage (1.9V versus 3V) and test current (10mA versus 20mA), which requires circuit design verification. These parts are available in multiple packaging formats (Bulk, Cut Tape, Tape & Reel) with substantial inventory levels.

Secondary Substitutes (Form Factor Compatible):

The HLMP-3301 series (HLMP-3301-D0001 and HLMP-3301-F00DD) also maintains T-1 3/4 form factor compatibility with diffused red lens characteristics. These components operate at 1.9V forward voltage with 10mA test current. The HLMP-3301-F00DD variant offers the highest inventory availability (43,381 pieces) among all substitutes.

The Dialight 521 series components (5219240F, 5219320F, 5219672F) provide through-hole mounting with diffused red lenses in 5mm form factors. The 5219672F offers the closest brightness match at 60mcd with 20mA test current and 60° viewing angle, though it operates at 2V forward voltage.

Tertiary Substitute (Brightness Consideration):

The Everlight Electronics 333-2SDRD/S530-A3 provides a diffused red 5mm through-hole LED with significantly higher brightness (160mcd) and operates at 2V forward voltage with 20mA test current. This component is suitable for applications where increased luminous intensity is acceptable or required.

Product Status Compliance:

All substitute parts listed are active products with confirmed ROHS3 compliance and MSL 1 moisture sensitivity rating, ensuring regulatory compliance and long-term availability for production and replacement applications.

Frequently Asked Questions (FAQ)

Q: Why is the SSL-LX5093BHD classified as obsolete?

A: The SSL-LX5093BHD is no longer in active production by Lumex Opto/Components Inc. Substitute parts from active manufacturers (Broadcom Limited, Dialight, Everlight Electronics) provide equivalent functionality with confirmed long-term availability.

Q: Can I directly replace the SSL-LX5093BHD with an HLMP-3351 variant without circuit modification?

A: Direct replacement requires circuit design verification. The SSL-LX5093BHD operates at 3V forward voltage with 20mA test current, while HLMP-3351 variants operate at 1.9V with 10mA test current. Current-limiting resistor values must be recalculated based on the substitute part's electrical characteristics and the circuit supply voltage.

Q: What is the significance of the T-1 3/4 form factor?

A: T-1 3/4 designates a 5mm diameter lens with a specific domed top profile. This form factor is mechanically compatible with standard 5mm LED mounting holes and bezels. All listed substitutes maintain this form factor, ensuring mechanical interchangeability in existing PCB layouts and mechanical assemblies.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed carry ROHS3 compliance certification, meeting regulatory requirements for hazardous substance restrictions in electronic components.

Q: What is the difference between the various HLMP-3351 part numbers?

A: The HLMP-3351 variants differ primarily in packaging format and millicandela rating. HLMP-3351-D0000 and HLMP-3351-D0002 are rated at 2.1mcd, while HLMP-3351 and HLMP-3351-F00R1 are rated at 5.4mcd. Packaging options include Bulk, Cut Tape (CT), and Tape & Reel (TR). All variants maintain identical electrical specifications (1.9V, 10mA) and mechanical form factor.

Q: Does the SSL-LX5093BHD flashing feature have an equivalent in the substitute parts?

A: The flashing feature is specific to the SSL-LX5093BHD and is not replicated in the listed substitute parts. If flashing functionality is required, external circuit implementation (oscillator circuit with switching transistor) is necessary, or alternative flashing LED components must be sourced separately.

Q: What is the viewing angle significance for LED indicator applications?

A: Viewing angle determines the cone of light distribution from the LED. The SSL-LX5093BHD has a 60° viewing angle. Substitute parts range from 30° (narrow, directional) to 60° (wide, omnidirectional). Selection depends on the application's visibility requirements and mounting orientation.

Q: Can I use the 5219672F as a direct substitute if brightness is not a constraint?

A: The 5219672F is mechanically and electrically compatible for applications where the 60mcd brightness and 2V forward voltage are acceptable. Circuit design verification is required to confirm that the 20mA test current and 2V forward voltage operate correctly within the existing circuit topology.

Q: What packaging options are available for production applications?

A: Substitute parts are available in multiple packaging formats: Bulk (loose components), Cut Tape (CT) for semi-automated assembly, and Tape & Reel (TR) for fully automated pick-and-place equipment. Selection depends on production volume and assembly equipment capabilities.

Q: Are all substitute parts available in current inventory?

A: Yes. All substitute parts listed have confirmed inventory availability ranging from 43 pieces (HLMP-3301-F00DD minimum) to 43,381 pieces (HLMP-3301-F00DD maximum). Specific availability should be verified with component suppliers for production requirements.
