LED GRN/YLW DIFFUSED 0606 SMD 7018X5/7 Equivalent & Substitute Parts

Part Overview

The Visual Communications Company (VCC) 7018X5/7 is a surface mount LED indicator featuring independent green and yellow light emission in a compact 0606 (1616 Metric) package. This component provides discrete dual-color indication with diffused lens optics, delivering 6.8mcd green and 16mcd yellow output at specified test currents.

The 7018X5/7 is classified as obsolete. Locating equivalent substitute components is necessary to support ongoing production requirements, maintenance operations, and design continuity where this part number is specified in active applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 7018X5/7 is determined by the following critical parameters:

Mechanical Compatibility:

• Package type: 0606 (1616 Metric) surface mount
• Physical dimensions: 1.60mm L x 1.50mm W, 0.70mm maximum height
• Mounting type: Surface mount configuration

Electrical Compatibility:

• Dual-color independent configuration (green and yellow)
• Forward voltage range: Green 2.1V nominal, Yellow 1.75V nominal
• Test current: 20mA for both colors
• Wavelength specifications: Green 560nm peak, Yellow 580nm peak

Optical Characteristics:

• Lens style: Rectangle with flat top
• Lens size: 1.10mm x 1.50mm
• Viewing angle: 110° minimum

Regulatory & Environmental:

• RoHS3 compliance required
• MSL rating consideration for storage and handling

The Lumex Opto/Components Inc. SML-LX0606YGC-TR meets the mechanical package requirements and electrical configuration criteria, with allowable variations in forward voltage, luminous intensity, and lens transparency characteristics.

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility:

The Lumex Opto/Components Inc. SML-LX0606YGC-TR is a functional substitute for the obsolete VCC 7018X5/7 based on identical mechanical package specifications, matching surface mount configuration, and compatible electrical test parameters.

Compliance Status:

Both components maintain ROHS3 compliance, satisfying regulatory requirements for lead-free and restricted substance standards. The substitute part is currently in active production status, ensuring ongoing availability and supply chain continuity.

Parameter Variations:

The substitute exhibits the following deviations from the original specification:

• Forward voltage increases of +0.1V (green) and +0.35V (yellow) fall within typical LED manufacturing tolerances and require circuit validation for current-limiting resistor adjustment
• Luminous intensity differs by +3.2mcd (green) and -6mcd (yellow), affecting brightness perception in indication applications
• Viewing angle expands to 120° from 110°, providing broader visibility
• Lens transparency changes from diffused to clear, altering light distribution and appearance
• Moisture sensitivity level increases from MSL 1 to MSL 3, requiring enhanced storage and handling protocols with 168-hour maximum floor life

Application Considerations:

Selection of the SML-LX0606YGC-TR requires validation that circuit design accommodates the higher forward voltage specifications and that the clear lens optical characteristics align with intended indication visibility requirements. Storage conditions must comply with MSL 3 moisture sensitivity limits.

Frequently Asked Questions (FAQ)

Q: Can the SML-LX0606YGC-TR directly replace the 7018X5/7 without circuit modification?

A: Direct mechanical substitution is possible due to identical package dimensions and mounting type. However, the forward voltage increase of +0.1V (green) and +0.35V (yellow) may require adjustment of current-limiting resistor values to maintain specified test current at 20mA. Circuit validation is necessary.

Q: What is the primary difference between the diffused lens of the 7018X5/7 and the clear lens of the SML-LX0606YGC-TR?

A: The 7018X5/7 features a diffused lens that scatters light output across a wider area with reduced peak intensity. The SML-LX0606YGC-TR clear lens provides more directional light transmission. This affects visual appearance and brightness perception in the application. The substitute's 120° viewing angle compared to the original 110° partially compensates for this difference.

Q: Are both components RoHS compliant?

A: Yes, both the 7018X5/7 and SML-LX0606YGC-TR are ROHS3 compliant, meeting lead-free and restricted substance requirements.

Q: What does the MSL 3 rating on the substitute part mean for handling?

A: MSL 3 indicates a maximum floor life of 168 hours (7 days) at 30°C and 60% relative humidity after the component is removed from its moisture barrier bag. The original 7018X5/7 with MSL 1 has unlimited floor life. The substitute requires more stringent storage and handling protocols to prevent moisture absorption that could affect solderability and reliability.

Q: How do the luminous intensity ratings compare?

A: The 7018X5/7 delivers 6.8mcd green and 16mcd yellow. The SML-LX0606YGC-TR delivers 10mcd green and 10mcd yellow. The green output increases by 3.2mcd, while yellow output decreases by 6mcd. These differences affect brightness perception and may require optical design consideration in indication applications.

Q: Is the SML-LX0606YGC-TR currently available?

A: Yes, the SML-LX0606YGC-TR is classified as active product status with current manufacturing availability, unlike the obsolete 7018X5/7.

Q: What is the wavelength difference between the two parts?

A: The 7018X5/7 operates at 560nm (green) and 580nm (yellow) peak wavelengths. The SML-LX0606YGC-TR operates at 565nm (green) and 585nm (yellow), representing +5nm shifts in both colors. These variations fall within standard LED color specification ranges and are not visually distinguishable in typical indication applications.
