Product details
Overview
VLMW41R1T1-5K8L-08 from Vishay Semiconductors is a white surface-mount LED using InGaN/TAG-on-sapphire technology, delivering 112–355 mcd luminous intensity at 10 mA, with forward voltage 3.3–4.2 V at 20 mA and ±60° viewing angle. It serves as a compact, AEC-Q101-qualified indicator light in automotive interior/exterior systems.
For engineers reviewing the VLMW41R1T1-5K8L-08 datasheet, VLMW41R1T1-5K8L-08 pinout, VLMW41R1T1-5K8L-08 application, or VLMW41R1T1-5K8L-08 equivalent, key selection criteria include luminous intensity binning (R-group), CIE 1931 chromaticity coordinates (x=0.33, y=0.33), PLCC-2 package compatibility with reflow soldering, and thermal resistance of 360 K/W.
Technical Context
This device employs blue-emitting InGaN die coupled with TAG phosphor in epoxy to generate white light via partial wavelength conversion. Its PLCC-2 package features a white thermoplastic body with integrated reflector and lead frame construction.
Designed for stable operation across –40 °C to +100 °C ambient temperature, it supports JEDEC level 2a preconditioning, withstands 2 kV ESD (HBM), and meets AEC-Q101 for automotive reliability. The 360 K/W junction-to-ambient thermal resistance assumes mounting on PCB pads >16 mm².
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar white SMD LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VLMW41S1T1-5K8L-08 | Higher luminous intensity bin (S-group: 180–224 mcd min) with identical package, VF, and chromaticity | Better suited for applications requiring higher visibility at same drive current | Select when brightness margin is critical and board space/layout remains unchanged |
| OSRAM LWT67C-8L | Same PLCC-2 package, 5500 K CCT, ±60° viewing angle, but rated for 30 mA IF and 100 °C Tj | Higher current capability supports brighter output but requires updated thermal layout | Choose for higher-output designs where thermal management can be enhanced |
Compared with VLMW41R1T1-5K8L-08, the S1 variant offers +60% minimum luminous intensity in the same footprint and drive conditions, while the OSRAM LWT67C-8L enables +50% current headroom at the cost of tighter thermal design constraints.

FAQ
What is the luminous intensity range of the VLMW41R1T1-5K8L-08?
The VLMW41R1T1-5K8L-08 has a luminous intensity range of 112–355 mcd at 10 mA, corresponding to the R-group binning (112–140 mcd minimum). This value is measured using a 25 ms current pulse and carries ±11% measurement accuracy per Vishay specification document 81370.
Is the VLMW41R1T1-5K8L-08 suitable for automotive applications?
Yes, the VLMW41R1T1-5K8L-08 is AEC-Q101 qualified and rated for operating temperatures from –40 °C to +100 °C, making it suitable for automotive brake lights, turn signals, side markers, and interior backlighting where reliability under thermal and vibration stress is required.
What does the "5K8L" suffix indicate in VLMW41R1T1-5K8L-08?
The "5K8L" suffix identifies the chromaticity bin: "8L" denotes the CIE 1931 coordinate group with x = 0.33 and y = 0.33, while "5K" refers to an earlier binning subset within the same white point family. Vishay uses this coding to guarantee consistent color matching across production reels.
Can the VLMW41R1T1-5K8L-08 be soldered using standard reflow profiles?
Yes, the VLMW41R1T1-5K8L-08 is compatible with Pb-free reflow soldering per J-STD-020, supporting peak temperatures up to 260 °C for ≤10 seconds. It also supports vapor-phase and wave soldering per CECC 00802, with JEDEC level 2a preconditioning applied.
What is the thermal resistance of the VLMW41R1T1-5K8L-08?
The VLMW41R1T1-5K8L-08 has a thermal resistance of 360 K/W (junction-to-ambient), measured with the device mounted on a PCB pad area exceeding 16 mm². This value directly impacts maximum allowable DC forward current (20 mA) and sustained brightness stability at elevated ambient temperatures.
