VLMY3001-GS18 Equivalent & Substitute Parts

Part Overview

The VLMY3001-GS18 is a yellow 588nm LED indication component manufactured by Vishay Semiconductor Opto Division in a 2-SMD, J-Lead surface mount package. This part is classified as obsolete, making identification of equivalent and substitute components necessary for ongoing design support and production continuity. The component operates at 1.8V forward voltage with a 2mA test current and delivers 13mcd luminous intensity through a clear round lens with 120° viewing angle.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the VLMY3001-GS18 are identified based on strict parametric alignment within the following criteria:

Primary Substitution Criteria (Parametric Equivalent):

• Color: Yellow
• Wavelength - Dominant: 588nm
• Voltage - Forward (Vf): 1.8V
• Current - Test: 2mA
• Lens Style: Round with Flat Top
• Lens Size: 2.40mm Dia
• Viewing Angle: 120°
• Package / Case: 2-SMD, J-Lead
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant

The parametric equivalent VLMY30J2M1-GS08 maintains all critical electrical and mechanical parameters with only minor variations in millicandela rating (14mcd vs. 13mcd) and product status (Active vs. Obsolete). This part is suitable for direct substitution in applications where the VLMY3001-GS18 is specified.

Secondary Substitution Category (Manufacturer Recommended): The VSEW1154LDS-E-3D4N4-TR represents a manufacturer-recommended alternative from Stanley Electric Co. This part differs significantly in color (White), forward voltage (3.4V), test current (30mA), and millicandela rating (2300mcd). This substitution is applicable only when circuit design accommodates the different electrical characteristics and visual output requirements.

Parameter Comparison

Engineering Selection Recommendations

For Direct Substitution (Parametric Equivalent): The VLMY30J2M1-GS08 is the appropriate choice for applications requiring functional equivalence to the VLMY3001-GS18. This part maintains identical electrical specifications (1.8V, 2mA) and mechanical form factor while offering active product status and improved availability. Both parts are ROHS3 compliant with identical MSL ratings, ensuring compatibility in existing designs without circuit modification.

For Alternative Applications (Manufacturer Recommended): The VSEW1154LDS-E-3D4N4-TR should be selected only when circuit design can accommodate significantly different operating parameters: 3.4V forward voltage, 30mA test current, and substantially higher luminous intensity (2300mcd). This part is suitable for applications where increased brightness is beneficial and power supply design permits the higher voltage and current requirements. The different MSL rating (3 vs. 2A) requires consideration in moisture-sensitive manufacturing environments.

Frequently Asked Questions (FAQ)

Q: Can VLMY30J2M1-GS08 be used as a direct replacement for VLMY3001-GS18? A: Yes. The VLMY30J2M1-GS08 maintains identical electrical parameters (1.8V forward voltage, 2mA test current), mechanical dimensions, and package configuration. The only differences are product status (Active vs. Obsolete) and a minor increase in millicandela rating (14mcd vs. 13mcd), which does not affect circuit compatibility.

Q: What are the key differences between the parametric equivalent and manufacturer-recommended substitute? A: The parametric equivalent (VLMY30J2M1-GS08) maintains the same color, voltage, and current specifications as the original part. The manufacturer-recommended substitute (VSEW1154LDS-E-3D4N4-TR) is a different color (White), operates at higher voltage (3.4V), requires higher current (30mA), and delivers significantly higher brightness (2300mcd). Circuit redesign is necessary for the manufacturer-recommended option.

Q: Are there packaging differences between these parts? A: The VLMY3001-GS18 and VLMY30J2M1-GS08 use identical 2-SMD, J-Lead packaging. The VSEW1154LDS-E-3D4N4-TR uses 2-PLCC packaging with slightly larger dimensions (3.20mm L vs. 3.00mm L) and greater height (2.10mm vs. 1.85mm), requiring PCB layout verification before substitution.

Q: Do all parts meet the same compliance standards? A: All three parts are ROHS3 compliant and REACH unaffected. The VLMY3001-GS18 and VLMY30J2M1-GS08 share identical MSL ratings (2A, 4 Weeks). The VSEW1154LDS-E-3D4N4-TR has a different MSL rating (3, 168 Hours), which may affect storage and handling procedures in moisture-sensitive manufacturing environments.

Q: Which substitute should be selected for new designs? A: For new designs requiring yellow LED indication at 1.8V with 2mA operation, the VLMY30J2M1-GS08 is the appropriate selection due to its active product status and parametric equivalence. This ensures long-term availability and design continuity.
