Engineering Selection Recommendations

Primary Component: SSL-LX5093SYC/G

The SSL-LX5093SYC/G maintains active product status with full ROHS3 compliance and REACH unaffected designation. This component is suitable for new designs and ongoing production applications requiring yellow LED indication with 16500mcd brightness output.

Substitute Component: OVLGY0C9B9

The OVLGY0C9B9 from TT Electronics/Optek Technology is qualified as a direct substitute based on:

• Identical mechanical form factor (5mm T-1 3/4 through-hole radial package)
• Equivalent electrical operation within specified tolerance (2.0V forward voltage vs. 2.1V)
• Compliant regulatory status (ROHS3, REACH unaffected, EAR99 classification)
• Yellow spectrum wavelength compatibility (589nm vs. 595nm)
• Acceptable brightness variation (14000mcd vs. 16500mcd) for indication applications
• Identical moisture sensitivity rating and environmental classification

Selection between these components should be based on:

1. Availability: OVLGY0C9B9 shows higher inventory (79595 pcs) compared to SSL-LX5093SYC/G (800 pcs)
2. Brightness Requirements: SSL-LX5093SYC/G provides higher luminous intensity; OVLGY0C9B9 suitable for standard indication applications
3. Viewing Angle: SSL-LX5093SYC/G offers wider 12° angle; OVLGY0C9B9 provides narrower 8° angle
4. Forward Voltage: OVLGY0C9B9 operates at 0.1V lower forward voltage, reducing power consumption by approximately 5%

Both components maintain identical compliance certifications and environmental ratings, ensuring interchangeability in applications where the specified parameter variations are acceptable.

Frequently Asked Questions (FAQ)

Q: Can OVLGY0C9B9 be used as a direct replacement for SSL-LX5093SYC/G in existing designs?

A: Yes. Both components share identical mechanical form factors (5mm T-1 3/4 through-hole radial), electrical test current (20mA), and regulatory compliance (ROHS3, REACH unaffected). The 0.1V forward voltage difference and 2500mcd brightness variation fall within acceptable ranges for yellow LED indication applications.

Q: What is the impact of the 4° viewing angle difference between these components?

A: The SSL-LX5093SYC/G provides a 12° viewing angle while OVLGY0C9B9 provides 8°. This difference affects light distribution characteristics. The narrower angle of OVLGY0C9B9 concentrates light output in a smaller cone, potentially increasing perceived brightness in the central viewing direction while reducing visibility at wider angles. Application-specific viewing requirements should determine which component is appropriate.

Q: Are there wavelength compatibility concerns between 595nm and 589nm?

A: No. Both wavelengths fall within the yellow spectrum range and are visually indistinguishable to the human eye. The 6nm difference represents normal manufacturing variation within yellow LED specifications and does not affect functional performance in indication applications.

Q: How does the 2500mcd brightness difference affect circuit design?

A: The SSL-LX5093SYC/G (16500mcd) provides approximately 18% higher luminous intensity than OVLGY0C9B9 (14000mcd). For standard indication applications, both brightness levels are sufficient. Applications requiring maximum visibility or operation in high ambient light conditions should specify the higher brightness SSL-LX5093SYC/G. Existing circuit designs do not require modification when substituting between these components at the standard 20mA test current.

Q: Do packaging differences affect PCB layout or assembly?

A: No. Both components use identical radial through-hole packages with 5mm lens diameter and T-1 3/4 form factor. PCB footprints, lead spacing, and mounting hole requirements are identical. The 0.7mm height difference (9.60mm vs. 8.90mm) is negligible for standard through-hole assembly and does not affect clearance or mechanical compatibility.

Q: What is the significance of the 0.1V forward voltage difference?

A: The OVLGY0C9B9 operates at 2.0V typical forward voltage compared to 2.1V for SSL-LX5093SYC/G. This 0.1V difference results in approximately 5% lower power consumption at 20mA test current. For current-limiting resistor calculations, this variation is within standard engineering tolerance and does not require circuit redesign. Existing resistor values remain valid for both components.

Q: Are both components suitable for new product designs?

A: Yes. Both components maintain active product status with full regulatory compliance. SSL-LX5093SYC/G is the primary specification; OVLGY0C9B9 is qualified as an equivalent substitute. Design selection should be based on availability, brightness requirements, and viewing angle specifications rather than regulatory or compliance considerations, as both meet identical standards.
