TLCY6800 Equivalent & Substitute Parts

Part Overview

The TLCY6800 is a yellow 590nm LED indication component manufactured by Vishay Semiconductor Opto Division, designed for through-hole mounting applications. This active product delivers 25000mcd at 2.1V forward voltage with an 8° viewing angle and clear lens configuration. Substitute parts are necessary when addressing supply constraints, inventory availability, or specific application requirements within compatible electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLCY6800 is determined by the following criteria:

Primary Compatibility Parameters:

• Color: Yellow (all substitutes must be yellow)
• Wavelength - Dominant: 590nm ±3nm range (588nm–593nm acceptable)
• Mounting Type: Through Hole (radial configuration)
• Voltage - Forward (Vf): 2.0V–2.1V range
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Secondary Consideration Parameters:

• Lens configuration (clear or diffused)
• Millicandela rating (brightness variation acceptable based on application)
• Viewing angle (application-dependent)
• Package dimensions (5mm form factor)

All four substitute parts meet the primary compatibility parameters and maintain active product status with full regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain ROHS3 compliance and active product status, ensuring regulatory alignment with the TLCY6800. Selection among substitutes depends on application-specific requirements:

151051YS04000 (Würth Elektronik): Operates at 2.0V forward voltage with reduced test current (20mA). Yellow diffused lens configuration provides wider 40° viewing angle. Brightness reduction to 450mcd requires circuit validation for indication-only applications.

OVLLY8C7 (TT Electronics/Optek Technology): Operates at 2.0V forward voltage with 20mA test current. Flat-top lens design with 100° viewing angle and 980mcd brightness. Compact 6.80mm height accommodates space-constrained layouts.

SSL-LX5093XYC (Lumex Opto/Components Inc.): Maintains 2.1V forward voltage matching TLCY6800 specification. Clear lens with 1300mcd brightness and 20° viewing angle. 8.60mm height compatible with standard through-hole spacing.

WP1503YC (Kingbright): Maintains 2.1V forward voltage with 20mA test current. Clear lens configuration with 30° viewing angle and 50mcd brightness. Highest inventory availability (20690 pcs) with standard 8.60mm height.

Frequently Asked Questions (FAQ)

Q: Can I use these substitute parts interchangeably with the TLCY6800?

A: Substitution is valid within the specified electrical parameters (2.0V–2.1V forward voltage, yellow color, 588nm–593nm dominant wavelength). Circuit design must accommodate differences in brightness (millicandela rating) and viewing angle. Test current reduction from 50mA to 20mA in substitutes requires circuit validation.

Q: What is the impact of different millicandela ratings?

A: The TLCY6800 delivers 25000mcd, while substitutes range from 50mcd to 1300mcd. Brightness differences affect visibility distance and application suitability. Indication-only applications tolerate lower brightness; high-visibility applications may require the original part or brightness-matched alternatives.

Q: How do lens transparency differences affect performance?

A: Clear lenses (TLCY6800, OVLLY8C7, SSL-LX5093XYC, WP1503YC) transmit full wavelength output. The diffused lens (151051YS04000) scatters light, reducing peak brightness but improving uniform visibility across wider angles (40° vs. 8°). Selection depends on application geometry and visibility requirements.

Q: Are all substitutes compatible with standard PCB through-hole spacing?

A: Yes. All parts use radial mounting with 5mm form factor and heights between 6.80mm and 9.00mm, compatible with standard 0.1-inch (2.54mm) PCB grid spacing. Verify clearance for components with 9.00mm height (TLCY6800) or 8.95mm height (151051YS04000) in compact layouts.

Q: What compliance certifications apply to all parts?

A: All parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 with HTSUS code 8541.41.0000. Moisture sensitivity level is 1 (Unlimited) for all parts, eliminating special handling requirements.
