Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SSL-DSP5093SOC are identified based on strict electrical and mechanical parameter compatibility within the orange LED T-1 3/4 through-hole category. The substitution logic is structured as follows:

Parametric Equivalent Classification: Parts classified as parametric equivalents match all critical electrical and mechanical specifications of the main part, including forward voltage (Vf), test current, lens size, mounting type, and package configuration. These parts are direct functional replacements with identical performance characteristics.

Similar Part Classification: Parts classified as similar maintain compatibility across the primary mechanical form factor (5mm T-1 3/4 through-hole radial package) and core functional purpose (orange LED indication). However, similar parts may exhibit variations in specific electrical parameters such as forward voltage, millicandela rating, or viewing angle. These variations remain within acceptable ranges for the LED indicator category but require engineering review for application-specific compatibility.

Key Parameters Determining Substitution:

• Lens size and style (5mm, T-1 3/4, round with domed top)
• Color (orange)
• Mounting type (through hole, radial)
• Lens transparency (clear)
• Forward voltage range (1.9V to 2V)
• Test current (20mA)
• Package configuration (radial)
• Compliance certifications (ROHS3, REACH)

Engineering Selection Recommendations

SSL-LX5093SOC (Parametric Equivalent - Recommended Primary Substitute)

The SSL-LX5093SOC is the recommended primary substitute for the obsolete SSL-DSP5093SOC. This part is manufactured by the same supplier (Lumex Opto/Components Inc.) and maintains identical electrical and mechanical specifications: 2V forward voltage, 2500mcd brightness, 30° viewing angle, 610nm peak wavelength, and 8.60mm maximum height. The SSL-LX5093SOC is classified as active product status, ensuring ongoing availability and supply chain continuity. Both parts are ROHS3 compliant and REACH unaffected, with identical moisture sensitivity ratings. The parametric equivalence of this part eliminates the need for circuit redesign or application re-qualification.

SLI-570DT3F (Similar Part - Secondary Substitute)

The SLI-570DT3F, manufactured by Rohm Semiconductor, is classified as a similar substitute. This part maintains the same mechanical form factor (5mm T-1 3/4 through-hole radial package) and core functional purpose (orange LED indication). The SLI-570DT3F exhibits the following parameter variations: forward voltage of 1.9V (compared to 2V), higher brightness of 3000mcd (compared to 2500mcd), narrower viewing angle of 20° (compared to 30°), and slightly greater maximum height of 8.85mm (compared to 8.60mm). The wavelength specification is provided as dominant wavelength of 611nm rather than peak wavelength. The SLI-570DT3F is active product status and maintains ROHS3 compliance and REACH unaffected status. Selection of this part requires verification that the application circuit can accommodate the 0.1V lower forward voltage and that the narrower 20° viewing angle meets optical requirements.

Both substitute parts maintain full compliance with environmental and regulatory standards applicable to the original component.

Frequently Asked Questions (FAQ)

Q: Can the SSL-LX5093SOC be used as a direct replacement for the SSL-DSP5093SOC without circuit modification?

A: Yes. The SSL-LX5093SOC is a parametric equivalent with identical forward voltage (2V), test current (20mA), brightness (2500mcd), viewing angle (30°), and physical dimensions (8.60mm height). No circuit redesign is required. Both parts are manufactured by Lumex Opto/Components Inc. and maintain identical compliance certifications.

Q: What are the key differences between the SSL-LX5093SOC and the SLI-570DT3F?

A: The SSL-LX5093SOC and SLI-570DT3F differ in the following parameters: forward voltage (2V vs. 1.9V), brightness (2500mcd vs. 3000mcd), viewing angle (30° vs. 20°), and maximum height (8.60mm vs. 8.85mm). The SLI-570DT3F is manufactured by Rohm Semiconductor rather than Lumex. Both parts maintain the same lens size (5mm T-1 3/4), mounting type (through hole), and compliance status (ROHS3, REACH unaffected).

Q: Is the SLI-570DT3F suitable for applications requiring a 30° viewing angle?

A: The SLI-570DT3F has a 20° viewing angle, which is narrower than the original SSL-DSP5093SOC specification of 30°. Applications requiring the full 30° viewing angle must use the SSL-LX5093SOC or verify that the narrower 20° angle is acceptable for the specific optical design.

Q: Will the 0.1V difference in forward voltage between the SSL-LX5093SOC (2V) and SLI-570DT3F (1.9V) affect circuit operation?

A: The 0.1V difference is within typical LED forward voltage tolerance ranges. However, circuit designs with tight voltage regulation or current-limiting resistor calculations should be reviewed. The SLI-570DT3F will draw slightly more current at a fixed voltage supply compared to the SSL-LX5093SOC. Verify that the application circuit can accommodate this variation.

Q: Are all three parts (SSL-DSP5093SOC, SSL-LX5093SOC, and SLI-570DT3F) mechanically compatible with the same PCB footprint?

A: Yes. All three parts use the same 5mm T-1 3/4 through-hole radial package configuration. The maximum height variations (8.60mm for SSL-DSP5093SOC and SSL-LX5093SOC, 8.85mm for SLI-570DT3F) are within standard PCB design tolerances and do not affect footprint compatibility.

Q: What is the inventory status for substitute parts?

A: The SSL-LX5093SOC has 11,146 pieces in stock (active product status). The SLI-570DT3F has 1,064 pieces in stock (active product status). The original SSL-DSP5093SOC has 1,088 pieces in stock but is classified as obsolete.

Q: Do both substitute parts maintain the same environmental compliance as the original SSL-DSP5093SOC?

A: Yes. Both the SSL-LX5093SOC and SLI-570DT3F are ROHS3 compliant and REACH unaffected, matching the compliance status of the original SSL-DSP5093SOC. Both parts have moisture sensitivity level (MSL) rating of 1 (Unlimited).
