SSL-LX5093IID Equivalent & Substitute Parts

Part Overview

The SSL-LX5093IID is a red diffused LED indicator manufactured by Lumex Opto/Components Inc., designed for through-hole mounting applications. This T-1 3/4 (5mm) radial LED operates at 2V forward voltage with a 20mA test current and delivers 20 millicandela of luminous intensity. The component is classified as Active product status with ROHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts are identified based on matching electrical characteristics, mechanical form factor, and optical properties. Alternative components serve applications where the original part is unavailable, where packaging formats differ, or where inventory constraints require sourcing from alternative manufacturers while maintaining functional equivalence.

Substitute Part Grouping Explanation

Substitute parts are grouped into two categories based on electrical and mechanical compatibility with the SSL-LX5093IID:

Category A - Direct Electrical Equivalents (2V Forward Voltage, 20mA Test Current)

Parts in this category match the primary electrical operating parameters of the SSL-LX5093IID. These components operate at identical forward voltage (2V) and test current (20mA), ensuring circuit-level compatibility without modification to current-limiting resistor values or power supply specifications. Substitutes in this group include:

5219672F (Dialight 521 Series) - 60mcd, 60° viewing angle, 623nm dominant wavelength
HLMP-D101 (Broadcom Limited) - 70mcd, 65° viewing angle, 637nm dominant wavelength

Category B - Reduced Electrical Parameters (Lower Vf and/or Lower Current)

Parts in this category operate at reduced forward voltage (1.8V to 1.9V) or reduced test current (2mA to 10mA). These components require circuit redesign to maintain equivalent brightness or may operate at reduced luminous intensity compared to the original specification. Substitutes in this group include:

5219240F (Dialight 521 Series) - 6.3mcd, 10mA test current, T-1 3/4 form factor

Engineering Selection Recommendations

Direct Substitution (No Circuit Modification Required)

The 5219672F (Dialight 521 Series) and HLMP-D101 (Broadcom Limited) are electrically equivalent to the SSL-LX5093IID at the 2V forward voltage and 20mA test current operating point. Both parts maintain red color, diffused lens transparency, and through-hole radial mounting. The 5219672F operates at identical electrical parameters with higher luminous intensity (60mcd versus 20mcd). The HLMP-D101 operates at 1.8V forward voltage with 20mA test current, delivering 70mcd luminous intensity. Both parts carry ROHS3 compliance and unlimited moisture sensitivity rating, matching the regulatory status of the original component.

Conditional Substitution (Circuit Redesign Required)

The HLMP-3301-F00DD, HLMP-3351, HLMP-3351-D0000, and HLMP-3351-D0002 (Broadcom Limited) operate at 1.9V forward voltage with 10mA test current. These parts require modification to current-limiting resistor values to maintain equivalent circuit operation. The reduced test current (10mA versus 20mA) results in lower luminous intensity output. All four parts maintain T-1 3/4 form factor, red color, diffused lens transparency, and ROHS3 compliance.

Form Factor Alternatives

The 5219320F (Dialight 521 Series) operates at 1.8V forward voltage with 2mA test current in a 5mm radial package. This part requires significant circuit redesign and delivers substantially reduced luminous intensity (2mcd). The HLMP-3301-F00B2 and HLMP-3600-D00B2 (Broadcom Limited) feature right-angle mounting configurations, suitable for applications requiring board-edge or perpendicular LED placement. The HLMP-3600-D00B2 operates at 5V voltage rating, requiring dedicated circuit design.

All substitute parts maintain ROHS3 compliance and unlimited moisture sensitivity rating, ensuring regulatory equivalence with the original SSL-LX5093IID component.

Frequently Asked Questions (FAQ)

Q: Can the 5219672F directly replace the SSL-LX5093IID without circuit modification?

A: The 5219672F operates at identical electrical parameters (2V forward voltage, 20mA test current) and maintains through-hole radial mounting. However, the 5219672F uses a 5mm radial package designation while the SSL-LX5093IID specifies T-1 3/4 form factor. Physical verification of PCB mounting hole compatibility is required. The 5219672F delivers 60mcd luminous intensity compared to 20mcd for the SSL-LX5093IID, resulting in increased brightness.

Q: What is the difference between the HLMP-3351, HLMP-3351-D0000, and HLMP-3351-D0002?

A: All three parts share identical electrical specifications (1.9V forward voltage, 10mA test current), mechanical form factor (T-1 3/4), and mounting type (through-hole radial). The primary difference is luminous intensity: HLMP-3351 delivers 5.4mcd while HLMP-3351-D0000 and HLMP-3351-D0002 deliver 2.1mcd. The HLMP-3351-D0002 is supplied in cut tape packaging while HLMP-3351-D0000 is supplied in bulk packaging. Both variants are listed as substitute parts in the original SSL-LX5093IID documentation.

Q: Why do some substitute parts require circuit redesign?

A: Substitute parts with reduced forward voltage (1.8V to 1.9V versus 2V) or reduced test current (10mA or 2mA versus 20mA) operate at different electrical operating points. Current-limiting resistor values must be recalculated to maintain proper LED operation and prevent excessive current draw or insufficient brightness. Circuit redesign ensures the substitute part operates within its specified electrical ratings.

Q: Are all substitute parts ROHS3 compliant?

A: All substitute parts listed carry ROHS3 compliance certification, matching the regulatory status of the SSL-LX5093IID. All parts also maintain unlimited moisture sensitivity rating (MSL 1), ensuring equivalent environmental handling requirements.

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

A: The T-1 3/4 designation specifies a 5mm diameter lens with a domed top profile. This form factor determines mechanical fit in standard 5mm LED mounting holes on printed circuit boards. Substitute parts using alternative form factors (such as 5mm radial or right-angle configurations) may require PCB redesign or mechanical adaptation for proper installation.

Q: Can the HLMP-3600-D00B2 substitute for the SSL-LX5093IID?

A: The HLMP-3600-D00B2 operates at 5V voltage rating, significantly different from the SSL-LX5093IID 2V specification. This part requires dedicated circuit design with appropriate voltage regulation or current-limiting components. The right-angle mounting configuration differs from the radial configuration of the original part. The HLMP-3600-D00B2 is suitable only for applications where 5V operation and right-angle mounting are acceptable design modifications.

Q: What viewing angle differences exist among substitute parts?

A: The SSL-LX5093IID specifies 60° viewing angle. Substitute parts vary between 50° and 65° viewing angles. A narrower viewing angle (50°) concentrates light output in a tighter cone, while a wider viewing angle (65°) distributes light across a broader area. Selection depends on application requirements for LED visibility from specific viewing positions.

Q: How does wavelength variation affect substitution?

A: The SSL-LX5093IID specifies 635nm peak wavelength, classified as standard red. Substitute parts maintain peak wavelengths between 635nm and 645nm, all within the red spectrum classification. Dominant wavelengths range from 623nm to 637nm. These variations produce visually similar red color output suitable for indicator applications. Wavelength differences become significant only in applications requiring precise color matching or spectral analysis.
