VLMP31G2J2-GS08 Equivalent & Substitute Parts

Part Overview

The VLMP31G2J2-GS08 is a green 560nm LED indication component manufactured by Vishay Semiconductor Opto Division in the VLM.3 series. This 2-SMD, J-Lead surface mount LED features a 2.1V forward voltage, 5mcd brightness rating, and 120° viewing angle in a 2-PLCC package. The product is currently obsolete, necessitating identification of equivalent and substitute components for ongoing design requirements and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the VLMP31G2J2-GS08 is determined by the following critical parameters: color (green), package type (2-SMD, J-Lead / 2-PLCC), mounting method (surface mount), forward voltage (2.1V nominal), wavelength range (560nm dominant), viewing angle (120°), and lens transparency (clear). Substitute parts are grouped into two categories based on compatibility level:

Direct Equivalents (Parametric Match): Parts maintaining identical or near-identical electrical and mechanical specifications within the same package family, enabling direct board-level substitution without circuit redesign.

Functional Alternatives (Cross-Manufacturer): Parts from alternative manufacturers meeting the core functional requirements of green LED indication but with variations in specific parameters such as wavelength, brightness rating, or package dimensions. These require engineering evaluation for application compatibility.

Engineering Selection Recommendations

VLMP3102-GS08 (Direct Equivalent - Recommended Primary Choice)

This Vishay component is the preferred direct substitute. It maintains identical forward voltage (2.1V), package configuration (2-SMD, J-Lead / 2-PLCC), wavelength specification (560nm dominant), viewing angle (120°), and physical dimensions. The millicandela rating of 4.95mcd is functionally equivalent to the 5mcd specification. The part is in active production status with ROHS3 compliance and higher inventory availability (5606 units), ensuring supply continuity. No circuit modifications are required for substitution.

VLMP31H2J2-GS08 (Parametric Equivalent - Secondary Choice)

This Vishay component provides identical electrical and optical specifications to the main part, including 5mcd brightness and 565nm peak wavelength. It is available in Tape & Reel packaging with active product status and ROHS3 compliance. The primary distinction is packaging format (TR vs. CT/Digi-Reel), which does not affect functional performance. This part is suitable for applications requiring exact parametric matching.

67-21SUGC/S400-A4/TR8 (Functional Alternative - Conditional Use)

This Everlight component shares the 2-SMD, J-Lead package and 120° viewing angle but introduces significant parameter variations: forward voltage of 3.3V (versus 2.1V), test current of 20mA (versus 10mA), and dominant wavelength of 525nm (versus 560nm). The substantially higher brightness rating (279mcd) may cause visual intensity mismatches in indication applications. Circuit redesign is required to accommodate the higher forward voltage. Use only when the wavelength shift and increased brightness are acceptable for the application.

67-21VGC/TR8 (Functional Alternative - Limited Compatibility)

This Everlight component operates at the same 2.1V forward voltage and 120° viewing angle but differs in package type (1411 / 3528 Metric versus 2-PLCC), physical dimensions (4.60mm L x 2.80mm W, 0.85mm height), lens transparency (diffused versus clear), and wavelength (571nm dominant). The significantly lower profile (0.85mm) and diffused lens alter optical and mechanical characteristics. PCB layout modifications are required. Use only when the reduced height and diffused lens properties are compatible with the application requirements.

Frequently Asked Questions (FAQ)

Q: Can VLMP3102-GS08 be used as a direct replacement for VLMP31G2J2-GS08 without any modifications?

A: Yes. VLMP3102-GS08 is a direct equivalent with identical electrical specifications (2.1V forward voltage, 10mA test current), optical properties (560nm wavelength, 120° viewing angle), and package configuration (2-SMD, J-Lead / 2-PLCC). No circuit or layout modifications are required. The only difference is packaging format (Cut Tape & Digi-Reel versus the original format), which does not affect performance.

Q: What are the key differences between the Vishay direct equivalents and the Everlight alternatives?

A: The Vishay parts (VLMP3102-GS08 and VLMP31H2J2-GS08) maintain the original 2.1V forward voltage, 560nm wavelength, and 2-PLCC package. The Everlight alternatives introduce variations: 67-21SUGC/S400-A4/TR8 requires 3.3V and 20mA with a 525nm wavelength shift, while 67-21VGC/TR8 uses a different package type (1411) with reduced height and diffused lens. These differences necessitate application-specific evaluation.

Q: Is the 4.95mcd brightness of VLMP3102-GS08 functionally equivalent to the 5mcd of the original part?

A: Yes. The 4.95mcd specification represents a 1% variance from the 5mcd rating and is within normal manufacturing tolerance for LED indication applications. This difference is not perceptible in typical indication circuits and does not require design changes.

Q: What packaging considerations apply when selecting a substitute?

A: The Vishay direct equivalents (VLMP3102-GS08 and VLMP31H2J2-GS08) use identical 2-PLCC packages and are mechanically interchangeable. The Everlight 67-21VGC/TR8 uses a 1411 package with different dimensions (4.60mm L x 2.80mm W, 0.85mm height), requiring PCB layout verification. The 67-21SUGC/S400-A4/TR8 maintains the 2-PLCC package but with slightly different dimensions (3.10mm L x 2.70mm W, 2.10mm height), which may require clearance verification in constrained layouts.

Q: Are all substitute parts RoHS3 compliant?

A: The Vishay parts (VLMP3102-GS08 and VLMP31H2J2-GS08) are explicitly ROHS3 compliant. RoHS compliance status is not specified in the provided data for the Everlight alternatives (67-21SUGC/S400-A4/TR8 and 67-21VGC/TR8). Verify RoHS compliance requirements with the manufacturer or supplier before final selection.

Q: Can the Everlight 67-21SUGC/S400-A4/TR8 be used in a 2.1V circuit?

A: No. This part requires 3.3V forward voltage and 20mA test current, compared to the original 2.1V and 10mA specifications. Direct substitution in a 2.1V circuit will result in insufficient brightness or non-operation. Circuit redesign is required to accommodate the higher voltage and current requirements.
