SSL-LX5093YC Yellow LED T-1 3/4 Through Hole Equivalent & Substitute Parts

Part Overview

The SSL-LX5093YC is an active yellow LED indication component manufactured by Lumex Opto/Components Inc., designed for through-hole mounting applications. This discrete 2.1V radial LED operates at 20mA test current and delivers 40mcd luminous intensity with a 30° viewing angle. The component features a clear colorless lens with round domed top in a standard 5mm T-1 3/4 package format.

Substitute parts become necessary when the primary component experiences extended lead times, inventory constraints, or when design flexibility permits selection from qualified alternatives meeting equivalent electrical and mechanical specifications. All substitute parts listed maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSL-LX5093YC is determined by strict alignment across the following critical parameters:

Primary Substitution Criteria:

• Color: Yellow
• Mounting Type: Through Hole
• Package Configuration: Radial
• Lens Size: 5mm T-1 3/4 form factor
• Voltage - Forward (Vf): 2.0V to 2.1V range
• Current - Test: 20mA
• Lens Transparency: Clear (colorless lens)
• Lens Style: Round with Domed Top
• RoHS Status: ROHS3 Compliant

Secondary Compatibility Parameters:

• Millicandela Rating: 40mcd to 50mcd (narrow brightness tolerance)
• Viewing Angle: 30° (narrow angle specification)
• Wavelength - Peak: 585nm to 590nm (yellow spectrum range)
• Height (Max): 8.60mm to 8.95mm (mechanical fit tolerance)

Parts meeting all primary criteria and falling within secondary parameter ranges qualify as direct substitutes. Parts with deviations in lens transparency, lens style, or viewing angle characteristics fall outside direct substitution scope.

Parameter Comparison

Engineering Selection Recommendations

WP1503YC (Kingbright) - Primary Substitute

The WP1503YC qualifies as the primary substitute for SSL-LX5093YC. Both components share identical forward voltage (2.1V), matching millicandela rating (50mcd vs 40mcd—within tolerance), identical viewing angle (30°), and equivalent mechanical form factor (5mm T-1 3/4, 8.60mm height). Lens configuration, transparency, and style are identical. Both maintain ROHS3 compliance and active product status. This substitute presents zero design modification requirements.

OVLLY8C7 (TT Electronics/Optek Technology) - Conditional Substitute

The OVLLY8C7 presents significant deviations from the primary specification. While maintaining yellow color, clear lens, and through-hole radial package, this component features a flat-top lens style (versus domed top), substantially higher millicandela rating (980mcd versus 40mcd), and significantly wider viewing angle (100° versus 30°). Forward voltage matches at 2V. Height is reduced to 6.80mm. This substitute is suitable only for applications where increased brightness and wider light distribution are acceptable or beneficial. Optical performance characteristics differ materially.

151051YS04000 (Würth Elektronik) - Not Recommended

The 151051YS04000 deviates from primary substitution criteria through diffused lens transparency (versus clear), yellow lens color (versus colorless), and substantially elevated millicandela rating (450mcd versus 40mcd). Viewing angle is 40° versus 30°. Lens size is 4.90mm diameter versus 5mm. These deviations result in materially different optical output characteristics and are not suitable for direct substitution in applications requiring clear lens and narrow viewing angle specifications.

Frequently Asked Questions (FAQ)

Q: Can WP1503YC replace SSL-LX5093YC in all applications?

A: Yes. The WP1503YC maintains electrical equivalence (2.1V forward voltage, 20mA test current), mechanical compatibility (5mm T-1 3/4 through-hole radial package, 8.60mm height), and optical similarity (40mcd to 50mcd brightness, 30° viewing angle, clear domed lens). Both components are ROHS3 compliant and active status. No circuit modifications are required.

Q: Why is OVLLY8C7 listed if it has 980mcd versus 40mcd?

A: OVLLY8C7 is listed as a substitute option for applications where increased brightness and wider light distribution (100° viewing angle) are acceptable design parameters. The component maintains yellow color, clear lens, through-hole mounting, and 2V forward voltage. However, the substantially higher millicandela rating and flat-top lens style represent material optical differences. Selection requires confirmation that the application can accommodate these performance characteristics.

Q: Is 151051YS04000 compatible with SSL-LX5093YC?

A: 151051YS04000 is not recommended as a direct substitute. The diffused lens transparency, yellow lens color, and 450mcd brightness rating create optical output characteristics fundamentally different from the clear-lens, 40mcd specification. The 4.90mm lens diameter also deviates from the 5mm standard. This component is suitable only for applications with different optical requirements.

Q: What is the significance of lens transparency (clear vs. diffused)?

A: Lens transparency directly affects light distribution and perceived brightness. Clear lenses concentrate light output in a narrow beam with high intensity in the viewing angle. Diffused lenses scatter light across a wider area with lower peak intensity. Applications requiring focused indication in a specific direction require clear lenses. Applications requiring broad ambient visibility benefit from diffused lenses. SSL-LX5093YC specifies clear transparency with 30° viewing angle.

Q: Can I use OVLLY8C7 if my circuit is designed for 40mcd brightness?

A: OVLLY8C7 delivers 980mcd—approximately 24.5 times higher brightness. This will produce excessive light output and may cause visual discomfort or circuit malfunction if brightness-limiting resistors are not recalculated. Additionally, the 100° viewing angle versus 30° creates different light distribution. Circuit redesign is required if OVLLY8C7 is selected.

Q: Are all substitute parts available in equivalent packaging quantities?

A: Packaging format (bulk) is consistent across all parts. Inventory availability varies: SSL-LX5093YC (1,002 pcs), 151051YS04000 (2,066 pcs), OVLLY8C7 (9,819 pcs), WP1503YC (20,690 pcs). Verify current inventory status with supplier before finalizing procurement decisions.

Q: Do all parts meet the same regulatory compliance standards?

A: Yes. All listed components maintain ROHS3 compliance, REACH unaffected status, and EAR99 ECCN classification. Moisture sensitivity level is 1 (Unlimited) for all parts. Regulatory continuity is maintained across all substitutes.
