Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VLMG3102-GS18 is determined by strict equivalence across the following critical parameters:

• Color: Green
• Wavelength - Dominant: 569nm
• Wavelength - Peak: 565nm
• Voltage - Forward (Vf) (Typ): 2.2V
• Current - Test: 10mA
• Lens Style: Round with Flat Top
• Lens Size: 2.40mm Dia
• Viewing Angle: 120°
• Package / Case: 2-SMD, J-Lead
• Size / Dimension: 3.00mm L x 2.80mm W
• Height (Max): 1.85mm
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 2A (4 Weeks)

The following parts meet these substitution criteria and are classified as parametric equivalents:

• VLMG3102-GS08
• VLMG3100-GS08
• VLMG3100-GS18

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts—VLMG3102-GS08, VLMG3100-GS08, and VLMG3100-GS18—are classified as active products with full ROHS3 compliance and identical moisture sensitivity ratings. The primary distinction between VLMG3102-GS08 and the VLMG3100 series lies in millicandela rating: VLMG3102-GS08 maintains 14.6mcd matching the main part, while VLMG3100-GS08 and VLMG3100-GS18 provide 16mcd output. All substitute parts are supplied in Tape & Reel packaging, offering improved supply chain availability compared to the obsolete main part.

Frequently Asked Questions (FAQ)

Q: Can VLMG3100-GS08 and VLMG3100-GS18 be used as direct replacements for VLMG3102-GS18?

A: Yes. Both parts maintain identical electrical characteristics (2.2V forward voltage, 10mA test current, 569nm dominant wavelength) and mechanical specifications (2-SMD J-Lead package, 3.00mm x 2.80mm x 1.85mm dimensions, 120° viewing angle). The VLMG3100 series provides increased luminous intensity at 16mcd versus 14.6mcd, which does not preclude substitution in applications where the original specification is met or exceeded.

Q: What is the difference between VLMG3102-GS08 and VLMG3102-GS18?

A: Both parts share identical electrical and mechanical parameters. The suffix designation (-GS08 versus -GS18) indicates packaging configuration. VLMG3102-GS18 was supplied in non-specified packaging and is now obsolete. VLMG3102-GS08 is an active equivalent supplied in Tape & Reel packaging.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts—VLMG3102-GS08, VLMG3100-GS08, and VLMG3100-GS18—are ROHS3 compliant with identical moisture sensitivity levels (2A, 4 Weeks).

Q: Does the increased millicandela rating of VLMG3100 series parts affect compatibility?

A: No. The VLMG3100 series provides 16mcd versus the original 14.6mcd. This represents increased luminous intensity within the same optical and electrical envelope, maintaining full compatibility with existing PCB layouts and electrical circuits.

Q: What packaging options are available for substitute parts?

A: All substitute parts are supplied in Tape & Reel (TR) packaging, which is standard for surface mount LED components and compatible with automated assembly processes.
