VLMY3100-GS18 Yellow LED 2-PLCC SMD Equivalent & Substitute Parts

Part Overview

The VLMY3100-GS18 is a yellow 588nm LED indication component manufactured by Vishay Semiconductor Opto Division in a 2-SMD, J-Lead package configuration. This part is classified as obsolete, which necessitates identification of active equivalent alternatives for ongoing production and procurement requirements. The component delivers 10mcd luminous intensity with a 120° viewing angle and operates at a typical forward voltage of 2.1V at 10mA test current. Substitute parts must maintain functional equivalence across optical, electrical, and mechanical parameters while meeting current product availability and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VLMY3100-GS18 is determined by strict equivalence across the following critical parameters:

Optical Parameters: Color (Yellow), dominant wavelength (588nm), peak wavelength (585nm), and millicandela rating (10mcd) must remain constant. These parameters define the LED's spectral output and luminous intensity characteristics.

Electrical Parameters: Forward voltage (Vf) and test current establish the component's operating point. Substitutes must operate within the same electrical class to ensure circuit compatibility without redesign.

Mechanical Parameters: Package type (2-SMD, J-Lead), lens style (Round with Flat Top), lens size (2.40mm diameter), physical dimensions (3.00 × 2.80mm), and maximum height (1.85mm) must be identical to ensure PCB footprint and assembly compatibility.

Environmental & Compliance Parameters: RoHS3 compliance, MSL rating (2A, 4 Weeks), and REACH status must be maintained.

The identified substitutes maintain full equivalence across all specified parameters while differing only in product status (active vs. obsolete) and packaging format (Tape & Reel vs. standard packaging).

Parameter Comparison

Engineering Selection Recommendations

VLMY3100-GS08 is the direct functional equivalent to VLMY3100-GS18. Both components share identical electrical characteristics (2.1V forward voltage at 10mA test current), optical specifications, and mechanical dimensions. The primary distinction is product status: VLMY3100-GS18 is obsolete while VLMY3100-GS08 is active. VLMY3100-GS08 is supplied in Tape & Reel packaging format, which is standard for high-volume production environments. This part is recommended for new designs and ongoing production requiring the 2.1V forward voltage specification.

VLMY30J2L1-GS08 is a parametric equivalent with identical optical and mechanical characteristics but operates at a lower forward voltage (1.8V at 2mA test current). This part is active and available in Tape & Reel format. Selection of VLMY30J2L1-GS08 requires circuit redesign to accommodate the reduced forward voltage and test current specifications. This part is suitable only when circuit topology permits operation at 1.8V forward voltage.

Both substitute parts maintain full RoHS3 compliance, REACH unaffected status, and identical MSL ratings (2A, 4 Weeks), ensuring compliance with current environmental and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can VLMY30J2L1-GS08 be used as a direct drop-in replacement for VLMY3100-GS18?

A: VLMY30J2L1-GS08 is not a direct drop-in replacement. While it maintains identical optical output (588nm dominant wavelength, 10mcd), lens geometry, and package dimensions, it operates at 1.8V forward voltage compared to 2.1V for the VLMY3100-GS18. Circuit redesign is required to accommodate the lower forward voltage specification.

Q: Is VLMY3100-GS08 a direct replacement for VLMY3100-GS18?

A: Yes. VLMY3100-GS08 is functionally equivalent across all electrical, optical, and mechanical parameters. The only differences are product status (active vs. obsolete) and packaging format (Tape & Reel vs. standard). No circuit modifications are required.

Q: What is the significance of the packaging format difference (standard vs. Tape & Reel)?

A: Tape & Reel packaging is the industry standard for automated surface mount assembly and high-volume production. Standard packaging may indicate manual handling or lower-volume distribution. Both formats contain identical components; the difference is in delivery and handling method.

Q: Are all three parts RoHS3 compliant?

A: Yes. VLMY3100-GS18, VLMY30J2L1-GS08, and VLMY3100-GS08 are all ROHS3 compliant and REACH unaffected, meeting current environmental regulatory requirements.

Q: What does the MSL rating 2A (4 Weeks) mean for component handling?

A: MSL 2A indicates Moisture Sensitivity Level 2, with a floor life of 4 weeks at 30°C and 60% relative humidity. Components must be stored in dry conditions and used within the specified timeframe after opening moisture barrier packaging.

Q: Can I use VLMY30J2L1-GS08 in a circuit designed for VLMY3100-GS18 without modifications?

A: No. The 0.3V forward voltage difference (2.1V vs. 1.8V) and different test current (10mA vs. 2mA) require circuit redesign. Current-limiting resistor values and power supply considerations must be recalculated for the lower voltage specification.
