VAOL-5LGE2 Equivalent & Substitute Parts

Part Overview

The VAOL-5LGE2 is a green diffused through-hole LED manufactured by Visual Communications Company (VCC), designed for indication applications with a dominant wavelength of 570nm. This component features a 4.80mm round domed lens, 2V forward voltage, and 150mcd brightness rating at 20mA test current. The part is classified as obsolete, necessitating identification of active equivalent components for new designs and ongoing production requirements. Substitute parts must maintain functional compatibility across electrical characteristics, mechanical form factor, and mounting specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VAOL-5LGE2 is determined by the following mandatory parameters:

Electrical Compatibility:

• Color must be green for indication function equivalence
• Dominant wavelength must fall within the green spectrum (570-575nm range acceptable for visual indication)
• Forward voltage (Vf) must be compatible with existing circuit design (2V nominal, with tolerance for 2.1V acceptable in most applications)
• Test current must be 20mA to maintain standardized operating conditions

Mechanical Compatibility:

• Mounting type must be through-hole radial configuration
• Lens transparency must be diffused to match optical performance
• Lens style must be round with domed top for form factor compatibility
• Physical dimensions must not exceed original height specification for PCB clearance

Regulatory & Compliance:

• RoHS3 compliance required for environmental standards
• ECCN and HTSUS classifications must align for supply chain continuity

The LTL2R3KG from Lite-On Inc. qualifies as a substitute based on these parameters, with documented variations noted in the parameter comparison table.

Engineering Selection Recommendations

Substitution Feasibility:

The LTL2R3KG is a valid substitute for the obsolete VAOL-5LGE2 based on electrical and mechanical parameter alignment. Both components are ROHS3 compliant and share identical ECCN and HTSUS classifications, ensuring regulatory continuity.

Key Considerations:

1. Voltage Tolerance: The 0.1V increase in forward voltage (2V to 2.1V) is within acceptable circuit design margins for most indication applications. Verify that existing current-limiting resistor values accommodate this variance without exceeding maximum rated current.

2. Brightness Variance: The LTL2R3KG provides 180mcd versus the original 150mcd. This 20% brightness increase may be acceptable or beneficial for indication purposes, depending on application requirements. Verify that increased brightness does not create unintended visual effects in the end application.

3. Physical Dimensions: The substitute features a 5mm lens diameter (versus 4.80mm) and 8.70mm maximum height (versus 7.60mm). Confirm PCB layout accommodates the larger lens diameter and verify vertical clearance for the additional 1.1mm height.

4. Compliance Status: The substitute is subject to REACH regulations (versus REACH Unaffected for the original). Ensure supply chain documentation and material declarations are obtained from the manufacturer.

5. Product Status: The LTL2R3KG is in active production with significantly higher inventory availability (10,043 pcs), providing supply chain stability compared to the obsolete VAOL-5LGE2.

Frequently Asked Questions (FAQ)

Q: Can the LTL2R3KG be used as a direct drop-in replacement for the VAOL-5LGE2?

A: The LTL2R3KG is electrically compatible and functionally equivalent for indication applications. However, it is not a direct drop-in replacement due to physical dimension differences. The larger lens diameter (5mm vs 4.80mm) and increased height (8.70mm vs 7.60mm) require verification of PCB layout and mechanical clearance before implementation.

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

A: The increase from 2V to 2.1V is within typical circuit design tolerances for LED indication circuits. Most current-limiting resistor designs accommodate this variance. Verify that the existing resistor value does not cause the LED to exceed its maximum rated current (typically 30mA for this class of component).

Q: Why is the substitute brighter (180mcd vs 150mcd)?

A: The brightness difference results from manufacturing variations between manufacturers and product generations. The higher brightness of the LTL2R3KG may enhance visibility in the application or require adjustment of circuit current if dimmer operation is required.

Q: Are there any supply chain or regulatory differences?

A: The LTL2R3KG is subject to REACH regulations, requiring material compliance documentation from Lite-On Inc. Both components share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications. The substitute has superior moisture sensitivity rating (MSL 1 vs MSL 2), providing longer shelf life.

Q: What should be verified before implementing the LTL2R3KG?

A: Perform the following verification steps: (1) Confirm PCB layout accommodates 5mm lens diameter; (2) Verify vertical clearance for 8.70mm maximum height; (3) Test circuit operation with 2.1V forward voltage to ensure current-limiting resistor performance; (4) Validate that increased brightness (180mcd) meets application requirements; (5) Obtain REACH compliance documentation from supplier.

Q: Is the LTL2R3KG available in the same packaging as the VAOL-5LGE2?

A: The VAOL-5LGE2 packaging is listed as "-" (not specified), while the LTL2R3KG is supplied in Bulk packaging. Confirm packaging requirements with your procurement department and verify that bulk packaging meets your assembly process specifications.
