Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLMG3100-GS08 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Color: Green
• Mounting Type: Surface Mount
• Viewing Angle: 120°
• Lens Style: Round with Flat Top
• Lens Size: 2.40mm Dia
• Voltage - Forward (Vf) (Typ): 2.2V
• Current - Test: 10mA

Secondary Considerations:

• Package form factor and footprint compatibility
• Wavelength range (dominant and peak)
• Brightness rating (millicandela)
• Physical dimensions and height constraints
• Compliance certifications (RoHS, REACH)

The VLMG3100-GS08 from Vishay maintains identical electrical and optical specifications while offering active product status and improved brightness (16mcd vs 9mcd). The 67-11/GHC-AT2V1/2T from Everlight Electronics represents an alternative package form (1411/3528 Metric) with significantly different physical dimensions and substantially higher brightness (630mcd), requiring design verification for footprint and optical intensity compatibility.

Parameter Comparison

Engineering Selection Recommendations

VLMG3100-GS08 (Preferred Substitute): This part is the direct equivalent to the TLMG3100-GS08. Both components share identical electrical characteristics (2.2V forward voltage, 10mA test current), optical properties (569nm dominant wavelength, 120° viewing angle), and package form factor (2-SMD, J-Lead). The VLMG3100-GS08 offers active product status, ensuring long-term availability and supply chain stability. Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings. The increased brightness (16mcd vs 9mcd) represents a performance enhancement suitable for most applications. This substitute requires no design modifications and provides direct footprint compatibility.

67-11/GHC-AT2V1/2T (Alternative Substitute): This Everlight component provides an alternative green LED in a different package form (1411/3528 Metric). The part maintains green color, 120° viewing angle, and 2.40mm lens diameter. However, significant differences exist: the wavelength shifts to 527nm (dominant), the brightness increases substantially to 630mcd, and the physical dimensions differ (4.60mm L vs 3.00mm L, 0.80mm height vs 1.75mm height). Forward voltage and test current specifications are not provided. This substitute requires PCB layout verification for footprint compatibility and circuit design review for brightness and wavelength implications. Selection is appropriate only when the alternative package form and enhanced brightness align with application requirements.

Frequently Asked Questions (FAQ)

Q: Can VLMG3100-GS08 directly replace TLMG3100-GS08 without PCB modifications?

A: Yes. The VLMG3100-GS08 maintains identical package form factor (2-SMD, J-Lead), footprint dimensions (3.00mm L x 2.80mm W), and electrical specifications (2.2V forward voltage, 10mA test current). Direct substitution on existing PCBs is supported without layout changes.

Q: What are the key differences between VLMG3100-GS08 and 67-11/GHC-AT2V1/2T?

A: The VLMG3100-GS08 uses the 2-SMD, J-Lead package with 1.75mm maximum height, while the 67-11/GHC-AT2V1/2T uses the 1411 (3528 Metric) package with 0.80mm maximum height. The Everlight part has significantly higher brightness (630mcd vs 16mcd) and a different wavelength (527nm vs 569nm). PCB footprint compatibility must be verified before selection.

Q: Are all substitute parts RoHS3 compliant?

A: The VLMG3100-GS08 is confirmed ROHS3 compliant with identical MSL rating (2A, 4 Weeks) to the original part. RoHS compliance status for the 67-11/GHC-AT2V1/2T is not specified in the provided data.

Q: How does the brightness difference affect circuit design?

A: The VLMG3100-GS08 provides 16mcd compared to the original 9mcd, representing a 78% increase. This enhancement typically requires no circuit modifications for indicator applications. The 67-11/GHC-AT2V1/2T at 630mcd represents a 70-fold increase, potentially requiring current-limiting resistor adjustment or optical diffusion considerations depending on application requirements.

Q: What is the wavelength significance for green LED substitution?

A: The TLMG3100-GS08 and VLMG3100-GS08 both operate at 569nm dominant wavelength (yellow-green spectrum). The 67-11/GHC-AT2V1/2T operates at 527nm (pure green spectrum). Wavelength selection affects color perception and compatibility with optical filters or color-matched indicator panels. Application-specific color matching requirements determine wavelength suitability.

Q: Is the VLMG3100-GS08 available in the same packaging format?

A: Yes. The VLMG3100-GS08 is supplied in Tape & Reel (TR) format, standard for production environments. The original TLMG3100-GS08 packaging format is not specified in the provided data. Both parts use identical 2-PLCC supplier device packaging.
