SSL-LX5093SRD/F Equivalent & Substitute Parts

Part Overview

The SSL-LX5093SRD/F 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 1.7V forward voltage with a 600mcd brightness rating and 60° viewing angle. The component is ROHS3 compliant and maintains active product status with 997 units in current inventory.

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. Substitution becomes necessary due to component availability fluctuations, supply chain constraints, or design optimization requirements.

Substitute Part Grouping Explanation

Substitute parts are classified into two categories based on parametric alignment with SSL-LX5093SRD/F:

Parametric Equivalent: SSL-LX5093SID shares the same base product number (SSL-LX5093), identical mechanical form factor (T-1 3/4, 5mm, radial through-hole), and equivalent electrical operating characteristics (forward voltage 2V, test current 20mA, viewing angle 60°). This part maintains functional interchangeability with minor brightness variance (700mcd vs. 600mcd) and wavelength shift (636nm vs. 660nm).

Similar Substitutes: Parts from Dialight (521 series), Broadcom (HLMP series), and other manufacturers are classified as similar when they share core parameters: red color, diffused lens, T-1 3/4 or 5mm form factor, through-hole radial mounting, and ROHS3 compliance. These parts exhibit variations in forward voltage (1.8V–2V), brightness (2mcd–70mcd), and wavelength (623nm–645nm), requiring circuit-level evaluation for specific applications.

Critical Parameters for Substitution:

Lens size and form factor (T-1 3/4 / 5mm)
Mounting type (through-hole radial)
Forward voltage range (1.7V–2V acceptable)
Test current (10mA–20mA)
Viewing angle (50°–65°)
Wavelength range (623nm–660nm)
RoHS3 compliance

Engineering Selection Recommendations

Primary Substitute - Parametric Equivalent: SSL-LX5093SID is the direct parametric equivalent, sharing identical base product designation and mechanical compatibility. Forward voltage increases from 1.7V to 2V, requiring circuit resistor recalculation for constant-current applications. Brightness increases to 700mcd with wavelength shift to 636nm. This part is suitable for direct replacement in designs tolerating ±0.3V forward voltage variation and brightness increase.

Secondary Substitutes - Similar Classification: HLMP-D101 (Broadcom) provides the closest brightness match (70mcd vs. 600mcd) among similar parts, with forward voltage 1.8V and 20mA test current matching the main part's electrical profile. Height increases to 9.19mm; verify PCB clearance before substitution.

5219672F (Dialight 521 series) operates at 2V forward voltage with 20mA test current and 60° viewing angle, providing moderate brightness (60mcd) with 635nm wavelength. Height reduces to 8.21mm, offering potential space optimization.

HLMP-3351-D0000 and HLMP-3351-D0002 (Broadcom) operate at reduced current (10mA) with significantly lower brightness (2.1mcd), suitable only for low-intensity indicator applications. Forward voltage 1.9V and compact height (6.35mm) enable space-constrained designs.

Compliance Verification: All listed substitutes maintain ROHS3 compliance, MSL Level 1 (unlimited moisture sensitivity), and REACH unaffected status, matching the main part's regulatory profile. Product status remains active for all candidates, ensuring long-term availability.

Frequently Asked Questions (FAQ)

Q: Can SSL-LX5093SID directly replace SSL-LX5093SRD/F without circuit modification?

A: SSL-LX5093SID shares identical mechanical form factor and base product number. Forward voltage increases from 1.7V to 2V; series resistor values must be recalculated to maintain constant current at 20mA. Brightness increases to 700mcd. Direct physical substitution is possible; electrical circuit adjustment is required.

Q: What is the brightness difference between the main part and substitute options?

A: SSL-LX5093SRD/F operates at 600mcd. SSL-LX5093SID provides 700mcd (17% increase). Dialight 5219672F delivers 60mcd (90% reduction). Broadcom HLMP-D101 provides 70mcd (88% reduction). Broadcom HLMP-3351 series operates at 2.1–5.4mcd (99% reduction). Select based on application brightness requirements.

Q: Are all substitute parts compatible with through-hole PCB mounting?

A: All listed substitutes feature through-hole radial mounting. Verify PCB hole spacing and lead diameter compatibility. Height variations range from 6.35mm (HLMP-3351 series) to 9.57mm (5219320F); confirm clearance above PCB surface.

Q: What wavelength options are available among substitutes?

A: Main part operates at 660nm peak wavelength. Substitutes range from 623nm (Dialight 5219672F dominant) to 645nm (Broadcom HLMP-D101 peak). All wavelengths fall within red spectrum; verify color perception requirements for human-visible indicator applications.

Q: Which substitute offers the closest electrical match to SSL-LX5093SRD/F?

A: SSL-LX5093SID (Lumex) provides closest match with identical 20mA test current and 60° viewing angle. Forward voltage increases 0.3V (1.7V to 2V). Broadcom HLMP-D101 offers alternative with 1.8V forward voltage and 20mA current, with higher brightness (70mcd) and extended viewing angle (65°).

Q: Are packaging format differences significant for substitution?

A: SSL-LX5093SRD/F ships in standard radial packaging. SSL-LX5093SID uses bulk packaging. Broadcom HLMP-3351-D0002 uses cut tape (CT). Dialight 521 series uses bulk. Packaging affects handling and reel compatibility; electrical and mechanical performance remain unchanged.

Q: Can lower-brightness substitutes (HLMP-3351 series) be used in high-visibility applications?

A: HLMP-3351 series operates at 2.1–5.4mcd, representing 99% brightness reduction from 600mcd main part. These parts are suitable only for low-intensity indicator applications where reduced visibility is acceptable. High-visibility applications require HLMP-D101 (70mcd) or SSL-LX5093SID (700mcd).
