Overview
VLMW41S1T2-MKNL-08 from Vishay Semiconductors is a white surface-mount LED using InGaN/sapphire die with TAG phosphor conversion, delivering 275 mcd typical luminous intensity at 10 mA, ±60° viewing angle, and chromaticity coordinates (x=0.33, y=0.33) for consistent color rendering in indicator and automotive lighting applications.
For engineers reviewing the VLMW41S1T2-MKNL-08 datasheet, VLMW41S1T2-MKNL-08 pinout, VLMW41S1T2-MKNL-08 application, or VLMW41S1T2-MKNL-08 equivalent, this device supports reflow, vapor-phase, and wave soldering per J-STD-020 and CECC 00802, meets AEC-Q101 qualification, and provides ESD withstand up to 2 kV per JESD22-A114-B.
Technical Context
This PLCC-2 packaged LED uses blue-emitting InGaN die coupled with TAG phosphor to generate white light via partial wavelength conversion; its thermal resistance junction-to-ambient is 360 K/W when mounted on a PCB pad >16 mm², enabling operation from −40 °C to +100 °C ambient.
The device exhibits a forward voltage of 3.3 V typical at 20 mA, with temperature coefficients of −3 mV/K for VF and −0.4 %/K for luminous intensity, supporting stable optical output across industrial and automotive temperature ranges.

Equivalent & Alternatives
The following parts are listed as comparable options for similar white SMD LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VLMW41S1T2-JKKL-08 | Chromaticity (x=0.30, y=0.28) - cooler white point, ~5700 K CCT vs. 5500 K | Better suited for applications requiring higher color temperature consistency in daylight simulation | Select when tighter x/y tolerance around cooler white is required; same PLCC-2 package and drive conditions |
| OSRAM LWT67C-SC1 | PLCC-2, 280 mcd typical, (x=0.313, y=0.329), JEDEC Level 2a, AEC-Q101 qualified | Identical form factor and qualification level; minor chromaticity shift may require recalibration in color-critical systems | Use as functional alternative where Vishay supply constraints exist; verify binning match for color-sensitive assemblies |
Compared with VLMW41S1T2-MKNL-08, the JKKL variant offers a measurably cooler white point ideal for daylight-matched indicators, while the OSRAM LWT67C-SC1 provides cross-manufacturer sourcing continuity with nearly identical photometric and thermal specs.

FAQ
What is the chromaticity coordinate specification for VLMW41S1T2-MKNL-08?
The VLMW41S1T2-MKNL-08 has chromaticity coordinates of (x = 0.33, y = 0.33) per CIE 1931, measured at 10 mA forward current. This value places it within a tightly controlled white bin optimized for consistent 5500 K color temperature performance. The coordinate group MK corresponds to this specific (x,y) pair and is verified per the manufacturer's binning documentation in Document Number 82411.
Is VLMW41S1T2-MKNL-08 qualified for automotive use?
Yes, VLMW41S1T2-MKNL-08 is AEC-Q101 qualified, confirming its reliability for automotive applications including brake lights, turn signals, and interior backlighting. The qualification covers stress testing for temperature cycling, humidity, mechanical shock, and ESD, aligning with requirements for non-safety-critical but mission-relevant lighting functions.
What is the maximum allowable forward current for VLMW41S1T2-MKNL-08?
The absolute maximum DC forward current for VLMW41S1T2-MKNL-08 is 20 mA at ambient temperatures ≤80 °C. Exceeding this rating risks accelerated lumen depreciation and junction overheating, especially given its 360 K/W thermal resistance. For continuous operation, 10–15 mA is recommended to maintain long-term photometric stability.
Can VLMW41S1T2-MKNL-08 be used with standard reflow soldering processes?
Yes, VLMW41S1T2-MKNL-08 is compatible with Pb-free reflow soldering per J-STD-020, supporting peak temperatures up to 260 °C for ≤10 seconds. Its PLCC-2 package and leadframe construction are validated for JEDEC Level 2a moisture sensitivity, and the device ships in dry-packed reels with desiccant and humidity indicator cards.
What does the "-08" suffix indicate in VLMW41S1T2-MKNL-08?
The "-08" suffix in VLMW41S1T2-MKNL-08 denotes the tape-and-reel packaging option: 8 mm antistatic blister tape, 1500 pieces per reel (GS08 format). This configuration supports automated SMT placement and complies with DIN IEC 40 (CO) 564 standards for cavity depth, cover tape adhesion, and reel dimensions.
