VLMP31G2J2-GS18 Equivalent & Substitute Parts

Part Overview

The VLMP31G2J2-GS18 is a green 560nm LED indication component manufactured by Vishay Semiconductor Opto Division in a 2-SMD, J-Lead surface mount package. This part operates at 2.1V forward voltage with a 5mcd millicandela rating and 120° viewing angle. The product is currently obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the VLMP31G2J2-GS18 is determined by the following critical parameters: color (green), package type (2-SMD, J-Lead), forward voltage (2.1V), viewing angle (120°), and mounting type (surface mount). Parts are grouped into two categories based on substitution compatibility:

Direct Manufacturer Equivalents (Vishay): Parts maintaining identical electrical characteristics, wavelength specifications, and package configuration. These parts are interchangeable with the original component.

Parametric Equivalents (Vishay): Parts from the same manufacturer series with matching core electrical parameters and package specifications, differing only in production status or packaging format.

Cross-Manufacturer Substitutes (Everlight): Parts from alternative manufacturers that meet the same functional requirements but may differ in specific parameters such as wavelength, millicandela rating, or package dimensions. These require circuit-level evaluation.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: VLMP3102-GS08 and VLMP31H2J2-GS08 are both active Vishay products maintaining the same electrical specifications, package configuration, and compliance certifications as the obsolete VLMP31G2J2-GS18. Both parts are ROHS3 compliant with identical MSL ratings. VLMP31H2J2-GS08 provides the closest parametric match with identical millicandela rating (5mcd) and peak wavelength (565nm).

For Cross-Manufacturer Substitution: Everlight parts 67-21SUGC/S400-A4/TR8 and 67-21VGC/TR8 are active alternatives but require circuit evaluation due to parameter deviations. The 67-21SUGC/S400-A4/TR8 operates at 3.3V forward voltage with significantly higher brightness (279mcd), necessitating current-limiting resistor recalculation. The 67-21VGC/TR8 uses a different package format (1411 vs. 2-SMD, J-Lead) with reduced height (0.85mm) and diffused lens transparency, affecting optical characteristics and PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can VLMP3102-GS08 directly replace VLMP31G2J2-GS18 in existing designs?

A: Yes. Both parts share identical forward voltage (2.1V), test current (10mA), viewing angle (120°), package type (2-SMD, J-Lead), and physical dimensions. The millicandela rating difference (4.95mcd vs. 5mcd) is within normal manufacturing tolerance. Both are ROHS3 compliant with matching MSL specifications.

Q: What are the key differences between VLMP31H2J2-GS08 and VLMP3102-GS08?

A: Both are Vishay active products with identical electrical and optical specifications. The primary difference is packaging format: VLMP31H2J2-GS08 is supplied in Tape & Reel (TR), while VLMP3102-GS08 is available in Cut Tape (CT) & Digi-Reel. Selection depends on procurement and assembly requirements.

Q: Why do Everlight substitutes show different forward voltages and brightness levels?

A: Cross-manufacturer LED designs differ in semiconductor structure and phosphor composition. The 67-21SUGC/S400-A4/TR8 operates at 3.3V with 279mcd brightness, requiring circuit redesign including resistor value adjustment. The 67-21VGC/TR8 uses a different package (1411 vs. 2-SMD, J-Lead) with diffused optics, affecting both electrical performance and optical distribution.

Q: Are there PCB layout considerations when substituting with Everlight parts?

A: Yes. The 67-21VGC/TR8 uses package type 1411 (3528 Metric) with different dimensions (4.60mm L x 2.80mm W, 0.85mm height) compared to the original 2-SMD, J-Lead format (3.00mm L x 2.80mm W, 1.85mm height). PCB footprint and clearance verification is required. The 67-21SUGC/S400-A4/TR8 maintains similar dimensions but with 2.10mm maximum height versus 1.85mm for the original part.

Q: What compliance certifications apply to substitute parts?

A: Vishay parts VLMP3102-GS08 and VLMP31H2J2-GS08 maintain ROHS3 compliance and 2A MSL (4 Weeks) ratings identical to the original. Everlight parts do not specify RoHS or MSL status in the provided data; compliance verification with the supplier is required for regulated applications.
