LED YELLOW CLEAR 1206 SMD - 7010X7 Equivalent & Substitute Parts

Part Overview

The 7010X7 is a yellow LED indication component in 1206 (3016 Metric) surface mount package manufactured by Visual Communications Company (VCC). This discrete LED operates at a forward voltage of 2.1V with a test current of 20mA and provides 12mcd luminous intensity. The product is classified as obsolete, making identification of suitable substitute components necessary for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 7010X7 is based on the following critical parameters that must align with the original component:

Primary Substitution Criteria:

• Color: Yellow
• Lens Transparency: Clear
• Package Classification: 1206 form factor
• Mounting Type: Surface Mount
• Forward Voltage Range: Compatible with 2.1V nominal operation
• Test Current: 20mA standard
• RoHS3 Compliance: Required for regulatory alignment

The SML-LX1206YC-TR from Lumex Opto/Components Inc. meets these substitution criteria. Both components share identical color, lens transparency, package family designation, and mounting methodology. The substitute part operates at 2V forward voltage (within acceptable tolerance of the 2.1V original specification) and maintains the same 20mA test current standard for yellow LEDs in this package class.

Parameter Comparison

Engineering Selection Recommendations

The SML-LX1206YC-TR qualifies as a direct substitute for the obsolete 7010X7 based on the following engineering factors:

Regulatory Compliance: Both components maintain ROHS3 compliance and carry identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, ensuring no regulatory barriers to substitution.

Electrical Compatibility: The forward voltage differential of 0.1V (2.1V vs. 2.0V) falls within standard tolerance ranges for LED circuit design. Both components operate at the industry-standard 20mA test current for this package class.

Physical Integration: The SML-LX1206YC-TR maintains 1206 package family compatibility with surface mount assembly processes. The dimensional increase (3.20mm L x 1.60mm W versus 3.00mm L x 1.50mm W) requires verification against PCB footprint design, though standard 1206 pads accommodate this variation.

Performance Enhancement: The substitute part delivers 39mcd versus the original 12mcd, representing a 225% increase in luminous intensity. The wider 130° viewing angle (versus 70°) provides improved visibility characteristics. These enhancements do not compromise circuit compatibility and may improve application performance.

Supply Continuity: The substitute part maintains active production status with 3056 units in stock, compared to the obsolete status of the original component with limited remaining inventory (996 units).

Frequently Asked Questions (FAQ)

Q: Can the SML-LX1206YC-TR directly replace the 7010X7 on existing PCBs?

A: The substitute part is compatible with standard 1206 surface mount footprints. However, the dimensional increase from 3.00mm x 1.50mm to 3.20mm x 1.60mm requires verification that the PCB pad layout accommodates the larger component. Most standard 1206 designs provide sufficient clearance for this substitution.

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

A: The difference between 2.1V and 2.0V is within typical LED manufacturing tolerances and does not require circuit redesign. Standard current-limiting resistor calculations for 20mA operation remain valid for both components.

Q: Why does the substitute part have higher millicandela rating?

A: The SML-LX1206YC-TR delivers 39mcd compared to the original 12mcd. This increased luminous intensity is a performance enhancement that does not create compatibility issues. Applications requiring the original brightness level can operate the substitute at reduced current if necessary.

Q: Are there differences in wavelength between these components?

A: The peak wavelength differs by 20nm (570nm versus 590nm). Both values fall within the yellow spectrum range. The substitute's 590nm wavelength represents a slightly more orange-toned yellow compared to the original 570nm specification. Visual perception differences depend on application context.

Q: What is the impact of the wider viewing angle?

A: The substitute provides a 130° viewing angle versus the original 70°. This wider angle improves visibility from off-axis positions and does not create compatibility concerns. Applications designed for the narrower 70° angle will function correctly with the wider angle substitute.

Q: How do moisture sensitivity levels compare?

A: The original component specifies MSL 4 (72 Hours), while the substitute specifies MSL 3 (168 Hours). The substitute's lower MSL rating indicates superior moisture resistance and reduced risk during storage and assembly processes.

Q: Is packaging format a consideration for substitution?

A: The original component uses standard packaging, while the substitute is supplied in Tape & Reel (TR) format. This difference affects procurement and assembly processes but does not impact component functionality or PCB integration.
