Product details
Overview
VLMR31Q2T1-GS08 from Vishay Semiconductors is an orange-red AlInGaP-on-GaAs surface-mount LED in PLCC-2 package, delivering 90–355 mcd luminous intensity at 20 mA, with dominant wavelength 612–624 nm and forward voltage 1.8–2.4 V. It serves as a high-brightness indicator or backlighting source in automotive dashboards, telecom equipment, and LCD panels.
For engineers reviewing the VLMR31Q2T1-GS08 datasheet, VLMR31Q2T1-GS08 pinout, VLMR31Q2T1-GS08 application, or VLMR31Q2T1-GS08 equivalent, key selection criteria include luminous intensity binning (Q2 group), ±60° viewing angle, AEC-Q101 qualification, IR-reflow compatibility, and non-diffused lens for light-pipe coupling.
Technical Context
This device uses AlInGaP-on-GaAs epitaxial technology to achieve high radiance in the orange-red spectrum (612–624 nm). Its PLCC-2 package features a white thermoplastic body with internal reflector and clear epoxy lens, enabling efficient light extraction and thermal management up to 125 °C junction temperature.
Designed for automated SMT assembly, VLMR31Q2T1-GS08 supports JEDEC level 2a preconditioning, withstands 2 kV ESD (HBM), and operates across –40 °C to +100 °C ambient range. The non-diffused lens provides directional emission ideal for backlighting and symbol illumination where optical coupling efficiency matters.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar visible-light indicator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LA T676-Q2T1-24 | OSRAM cross-reference; identical luminous intensity bin (Q2), same dominant wavelength range (612–624 nm), PLCC-2 package | No AEC-Q101 qualification stated; not automotive-grade | Select when cost or dual-sourcing drives preference and automotive qualification is unnecessary |
| VLMR31Q2T1-GS18 | Same die and binning; differs only in tape/reel packaging (8000 pcs vs. 1500 pcs per reel) | Identical optical/electrical performance; GS18 preferred for high-volume production | Choose GS18 for volume procurement; GS08 suits prototyping or low-MOQ builds |
Compared with LA T676-Q2T1-24 and VLMR31Q2T1-GS18, the VLMR31Q2T1-GS08 offers verified AEC-Q101 compliance and smaller reel quantity-making it optimal for automotive design-in and pilot runs where qualification and flexibility matter more than bulk cost.
