Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SSL-LX5093XSYC are identified based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Color: Yellow
• Mounting Type: Through Hole
• Package Type: Radial
• Lens Size: 5mm form factor
• Voltage - Forward (Vf): 2.0V to 2.1V range
• Current - Test: 20mA
• Wavelength - Peak: 588nm to 592nm range
• RoHS3 Compliance
• REACH Unaffected status

Secondary Consideration Parameters:

• Millicandela Rating (brightness)
• Viewing Angle
• Lens Transparency (Clear or Diffused)
• Lens Style (Domed or Flat Top)
• Height dimensions

Substitutes are grouped by their alignment with these parameters. Parts meeting primary criteria are considered direct functional equivalents, while variations in secondary parameters indicate application-specific suitability.

Parameter Comparison

Engineering Selection Recommendations

SSL-LX5093XSYC (Lumex Opto/Components Inc.) - Primary Reference

This part is the baseline specification. All substitute parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory compatibility across all options.

151051YS04000 (Würth Elektronik) - Diffused Lens Variant

This substitute features a diffused lens transparency and reduced millicandela rating (450mcd vs. 2500mcd). The diffused lens provides wider light distribution (40° viewing angle) compared to the clear lens of the main part. Forward voltage is 2.0V, within acceptable tolerance. Height is 8.95mm, marginally higher than the main part. This part is suitable for applications requiring broader light distribution with lower intensity requirements.

OVLLY8C7 (TT Electronics/Optek Technology) - Wide Viewing Angle Variant

This substitute maintains clear lens transparency and operates at 2.0V forward voltage. The millicandela rating is 980mcd, lower than the main part. The viewing angle is significantly wider at 100° compared to 10°. Height is 6.80mm, notably lower than the main part. This part is suitable for applications requiring wide-angle light distribution in space-constrained mounting environments.

WP1503YC (Kingbright) - Lowest Brightness Variant

This substitute matches the main part in forward voltage (2.1V), lens size (5mm T-1 3/4), and height (8.60mm). Lens transparency is clear. The millicandela rating is significantly lower at 50mcd. Viewing angle is 30°. This part is suitable for applications requiring minimal brightness with standard form factor compatibility.

All substitute parts are active products with full regulatory compliance. Selection should be based on specific application requirements for brightness, viewing angle, and physical dimensions.

Frequently Asked Questions (FAQ)

Q: Can the 151051YS04000 (Würth) directly replace the SSL-LX5093XSYC in all applications?

A: The 151051YS04000 is electrically compatible (2.0V forward voltage, 20mA test current, 590nm wavelength range). However, the diffused lens and reduced brightness (450mcd vs. 2500mcd) make it suitable only for applications where lower intensity and wider light distribution (40° vs. 10°) are acceptable. Physical dimensions are also slightly different (8.95mm height vs. 8.60mm).

Q: What is the key difference between the OVLLY8C7 and the main SSL-LX5093XSYC part?

A: The OVLLY8C7 provides a significantly wider viewing angle (100° vs. 10°) and lower brightness (980mcd vs. 2500mcd). It is also 1.8mm shorter (6.80mm vs. 8.60mm). These characteristics make it suitable for applications requiring broad light distribution in compact spaces, but not for applications requiring high-intensity narrow-beam indication.

Q: Is the WP1503YC (Kingbright) suitable as a direct replacement?

A: The WP1503YC matches the SSL-LX5093XSYC in forward voltage (2.1V), lens size (5mm T-1 3/4), and height (8.60mm). However, the brightness is substantially lower (50mcd vs. 2500mcd). This part is suitable only for applications where minimal brightness is required and the narrow 10° viewing angle is not critical.

Q: Do all substitute parts meet the same regulatory requirements?

A: Yes. All substitute parts listed are ROHS3 compliant and REACH Unaffected, matching the regulatory status of the SSL-LX5093XSYC.

Q: What is the primary criterion for selecting among these substitutes?

A: The primary selection criterion is the required brightness (millicandela rating) and viewing angle for the specific application. The SSL-LX5093XSYC provides the highest brightness (2500mcd) with the narrowest viewing angle (10°). The OVLLY8C7 provides the widest viewing angle (100°) with moderate brightness (980mcd). The 151051YS04000 provides moderate brightness (450mcd) with moderate viewing angle (40°). The WP1503YC provides minimal brightness (50mcd) with moderate viewing angle (30°).

Q: Are there any height restrictions that would eliminate certain substitutes?

A: Yes. If the application has strict height constraints, the OVLLY8C7 at 6.80mm maximum height is the most compact option. The SSL-LX5093XSYC, WP1503YC, and 151051YS04000 are all within 8.60mm to 8.95mm, suitable for standard through-hole mounting applications with typical clearance requirements.

Q: Can forward voltage differences affect circuit design?

A: The forward voltage range across all parts is 2.0V to 2.1V, a 0.1V difference. This narrow range is typically accommodated by standard LED current-limiting resistor calculations and does not require circuit redesign for most applications.
