VLMC3101-GS18 Equivalent & Substitute Parts

Part Overview

The VLMC3101-GS18 is a green 569nm LED indication component manufactured by Vishay Semiconductor Opto Division, configured as a 2-SMD, J-Lead surface mount device. This part operates at 1.9V forward voltage with a 2mA test current and delivers 1.6mcd luminous intensity through a clear round lens with flat top design. The VLMC3101-GS18 is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing production and design continuity. Substitute parts must maintain identical electrical characteristics, optical properties, and mechanical form factors to ensure direct interchangeability without circuit redesign.

Substitute Part Grouping Explanation

Substitution eligibility for the VLMC3101-GS18 is determined by strict equivalence across the following critical parameters:

  • Wavelength - Dominant: 569nm
  • Wavelength - Peak: 565nm
  • Voltage - Forward (Vf) (Typ): 1.9V
  • Current - Test: 2mA
  • Millicandela Rating: 1.6mcd
  • Viewing Angle: 120°
  • Lens Style: Round with Flat Top
  • Lens Size: 2.40mm Dia
  • Package / Case: 2-SMD, J-Lead
  • Size / Dimension: 3.00mm L x 2.80mm W
  • Height (Max): 1.85mm
  • Mounting Type: Surface Mount

All three substitute parts—VLMC3100-GS08, VLMC3100-GS18, and VLMC3101-GS08—meet these criteria. The primary distinction between the main part and substitutes is product status and packaging configuration. The VLMC3101-GS18 is supplied in bulk packaging, while all substitutes are available in Tape & Reel (TR) configuration. The VLMC3100 series represents the active production equivalent to the obsolete VLMC3101 series, with identical electrical and optical specifications.

Engineering Selection Recommendations

All three substitute parts are direct functional equivalents to the VLMC3101-GS18 based on identical electrical, optical, and mechanical specifications. Selection between substitutes should be based on the following factors:

Product Status: VLMC3100-GS08 and VLMC3100-GS18 are active production parts, ensuring long-term availability and supply chain stability. VLMC3101-GS08 is also active but represents the same obsolete series as the main part. For new designs and ongoing production, VLMC3100 series parts are preferred.

Packaging Configuration: The main part is supplied in bulk packaging. All substitutes are available in Tape & Reel (TR) configuration, which is standard for automated assembly processes. Packaging selection depends on production volume and assembly equipment compatibility.

Compliance: All parts maintain ROHS3 compliance, REACH Unaffected status, and identical moisture sensitivity levels, ensuring regulatory and environmental compatibility across all options.

Inventory Availability: VLMC3100-GS08 offers the highest inventory level at 21,652 pieces, followed by VLMC3100-GS18 at 13,604 pieces and VLMC3101-GS08 at 16,220 pieces.

Frequently Asked Questions (FAQ)

Q: Can VLMC3100-GS08, VLMC3100-GS18, and VLMC3101-GS08 be used interchangeably with VLMC3101-GS18?

A: Yes. All three parts are parametric equivalents with identical electrical characteristics (1.9V forward voltage, 2mA test current), optical properties (569nm dominant wavelength, 1.6mcd intensity, 120° viewing angle), and mechanical form factors (2-SMD J-Lead package, 3.00mm x 2.80mm x 1.85mm maximum height). Direct substitution requires no circuit modifications.

Q: What is the difference between VLMC3100 and VLMC3101 series parts?

A: The VLMC3100 series represents the active production line, while VLMC3101 is obsolete. Both series share identical electrical and optical specifications. The VLMC3100 series is recommended for new designs and ongoing production to ensure supply continuity.

Q: Does packaging format affect electrical or optical performance?

A: No. Bulk and Tape & Reel (TR) packaging formats contain identical components with identical performance characteristics. Packaging selection is determined by production volume, assembly equipment, and supply chain requirements, not by component performance.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. VLMC3101-GS18 and all three substitute parts are ROHS3 compliant with REACH Unaffected status, ensuring regulatory compatibility across all options.

Q: What is the moisture sensitivity level for these parts?

A: All parts, including the main part and substitutes, have a Moisture Sensitivity Level (MSL) of 2A with a 4-week floor life rating. Identical handling and storage requirements apply across all options.
