For engineers reviewing the VLMK31Q1R2-GS08 datasheet, VLMK31Q1R2-GS08 pinout, VLMK31Q1R2-GS08 application, or VLMK31Q1R2-GS08 equivalent, key selection criteria include luminous intensity binning (Q1R2 group), AEC-Q101 qualification, JEDEC level 2a preconditioning, 2 kV ESD rating, and compatibility with IR reflow per J-STD-020.
Technical Context
This device uses AlInGaP-on-GaAs semiconductor technology to achieve high-brightness red emission with narrow spectral peak (643 nm) and stable chromaticity across temperature. Its PLCC-2 thermoplastic package features a white reflector cavity and clear epoxy lens, enabling efficient light extraction and precise angular control.
The VLMK31Q1R2-GS08 operates within -40 °C to +100 °C ambient range, supports 30 mA DC forward current, and exhibits 400 K/W thermal resistance when mounted on ≥16 mm² PCB pad - making it suitable for space-constrained, thermally demanding automotive and industrial indicator designs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar red SMD LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VLMK31R1S1-GS08 | Higher luminous intensity bin (112–224 mcd) with same 630 nm dominant wavelength and PLCC-2 package | Better suited for applications requiring higher visibility at distance or under ambient light | Select when brightness consistency across wider intensity range is acceptable and higher output is needed |
| OSRAM LST676-Q1R2 | Direct cross-reference per Vishay's official crossing table; identical luminous intensity binning and optical specs | Same automotive and industrial use cases; differs in tape/reel labeling and traceability format | Choose for multi-source procurement strategy where OSRAM supply chain integration is preferred |
Compared with VLMK31Q1R2-GS08, the VLMK31R1S1-GS08 offers higher brightness but less tight binning control, while OSRAM LST676-Q1R2 provides identical photometric performance with alternate logistics and compliance documentation - both require no PCB layout changes.

This binning ensures consistent brightness across reels, with IVmax/IVmin ≤ 1.6 within each packaging unit. The value reflects measurement at 25 ms pulse width and ±11 % accuracy.
Is the VLMK31Q1R2-GS08 qualified for automotive applications?
Yes, the VLMK31Q1R2-GS08 is AEC-Q101 qualified, meaning it has passed stress tests for temperature cycling, humidity, mechanical shock, and ESD required for automotive electronic components. It operates from -40 °C to +100 °C and is commonly used in dashboard backlighting and switch illumination per Vishay's stated applications.
What is the package type and mounting compatibility of the VLMK31Q1R2-GS08?
The VLMK31Q1R2-GS08 uses a PLCC-2 surface-mount package with 2 terminals (anode and cathode), measuring 3.5 mm × 2.8 mm × 1.75 mm. It is compatible with automatic placement equipment and supports IR reflow, vapor-phase, and wave soldering per CECC 00802 and J-STD-020 - including peak temperatures up to 260 °C.
Does the VLMK31Q1R2-GS08 have ESD protection, and what is its rating?
The VLMK31Q1R2-GS08 has an ESD-withstand voltage of up to 2 kV according to JESD22-A114-B (HBM). This rating allows safe handling during standard SMT assembly processes without requiring additional ESD mitigation beyond standard antistatic protocols - confirmed in Vishay's Rev. 2.0 datasheet.
What is the dominant and peak wavelength of the VLMK31Q1R2-GS08?
The VLMK31Q1R2-GS08 has a dominant wavelength of 630 nm and a peak wavelength of 643 nm, both measured at 20 mA forward current. The dominant wavelength defines the perceived red hue under photopic vision, while the peak wavelength indicates the spectral emission maximum - critical for color-matching in multi-LED assemblies.
