Product details
Overview
VLMW33U2AA-5K8L-18 from Vishay Semiconductors is a high-efficiency white power SMD LED in PLCC-2 package, delivering 560–1400 mcd luminous intensity at 20 mA, with forward voltage 3.7–4.2 V and chromaticity coordinates (x=0.33, y=0.33) per CIE 1931, designed for automotive dashboard backlighting and industrial indicator applications.
For engineers reviewing the VLMW33U2AA-5K8L-18 datasheet, VLMW33U2AA-5K8L-18 pinout, VLMW33U2AA-5K8L-18 application, or VLMW33U2AA-5K8L-18 equivalent, this page provides verified optical, electrical, thermal, and packaging data-including AEC-Q101 qualification, ±60° viewing angle, and JEDEC level 2a moisture sensitivity-critical for automotive-grade LED selection and PCB layout validation.
Technical Context
This InGaN/TAG-on-SiC white LED uses phosphor-converted blue emission to achieve stable 5500 K correlated color temperature. Its PLCC-2 thermoplastic package integrates a reflective epoxy-phosphor cavity and lead frame optimized for thermal dissipation up to 110 °C junction temperature.
Rated for 30 mA DC forward current and 127 mW power dissipation, it features -4 mV/K forward voltage temperature coefficient and -0.5 %/K luminous intensity drift, enabling predictable performance across -40 to +100 °C operating range with RthJA = 400 K/W on ≥16 mm² PCB pad.
Key Specifications

|---|---|
| Luminous intensity | 560–1400 mcd at 20 mA - defines brightness binning for consistent visual output in multi-LED arrays |
| Forward voltage | 3.7–4.2 V at 20 mA - determines series resistor or driver voltage headroom requirements |
| Chromaticity coordinate | (x=0.33, y=0.33) per CIE 1931 - ensures tight white point control for color-critical UIs |
| Viewing angle | ±60° half-intensity - supports wide-angle illumination without secondary optics |

Equivalent & Alternatives
The following parts are listed as comparable options for similar white SMD LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LWT67C-S2V1 (OSRAM) | Lower luminous intensity (224–900 mcd), same PLCC-2 package and 5500 K CCT | Suitable for lower-brightness indicator roles; not rated for AEC-Q101 | Select when cost sensitivity outweighs automotive qualification and higher brightness bin U2AA is unnecessary |
| VLMW33S2V1-5K8L-08 (Vishay) | Same package and phosphor system but lower intensity bin (S2V1: 224–900 mcd); shipped on 1500-piece reel (GS08) | Matches VLMW33U2AA-5K8L-18 in color and thermal specs but targets cost-optimized non-automotive designs | Choose for prototyping or low-volume non-automotive use where 8000-piece GS18 reel quantity is excessive |
Compared with LWT67C-S2V1 and VLMW33S2V1-5K8L-08, VLMW33U2AA-5K8L-18 offers higher luminous intensity (U2AA bin), AEC-Q101 qualification, and 8000-piece GS18 reel packaging-making it the preferred choice for production automotive backlighting where brightness consistency, reliability, and supply continuity are critical.

FAQ
What is the maximum forward current rating for VLMW33U2AA-5K8L-18?
The absolute maximum DC forward current for VLMW33U2AA-5K8L-18 is 30 mA at ambient temperatures ≤ 70 °C. Operation above this value risks accelerated lumen depreciation and thermal runaway. For continuous operation at elevated ambient temperatures, derating per Fig. 1 in the datasheet is required-e.g., ~22 mA at 85 °C ambient. VLMW33U2AA-5K8L-18 must never exceed its 127 mW power dissipation limit.
Does VLMW33U2AA-5K8L-18 require special handling due to moisture sensitivity?
Yes, VLMW33U2AA-5K8L-18 is classified JEDEC level 2a and shipped in dry-packed aluminum bags with humidity indicator cards. After opening, it must be mounted within 672 hours at <30 °C / 60 % RH or stored at <10 % RH. If exposed beyond limits, baking at 60 °C for 96 hours (<5 % RH) is required before reflow. This protocol prevents popcorning during IR-reflow soldering per J-STD-020.
What does the "5K8L" suffix indicate in VLMW33U2AA-5K8L-18?
The "5K8L" suffix in VLMW33U2AA-5K8L-18 specifies the chromaticity bin group: "5K" denotes x=0.296/y=0.259 and "8L" denotes x=0.345/y=0.352 per the CIE 1931 chart on page 3 of the datasheet. The actual device shipped falls within the tighter 7L group (x=0.330/y=0.330), confirmed by the "-5K8L-18" designation indicating dual-bin traceability and final test verification for VLMW33U2AA-5K8L-18.
Is VLMW33U2AA-5K8L-18 compatible with lead-free reflow soldering processes?
Yes, VLMW33U2AA-5K8L-18 is fully compatible with lead-free reflow soldering per J-STD-020. Its recommended profile peaks at 245 °C (max 260 °C for ≤100 s), with ramp rates limited to 3 °C/s (up) and 6 °C/s (down). The PLCC-2 package passes JEDEC preconditioning level 2a and supports vapor-phase and wave soldering per CECC 00802-verified in Fig. 13 and Fig. 14 of the datasheet.
How is luminous intensity binned for VLMW33U2AA-5K8L-18, and what does "U2AA" mean?
VLMW33U2AA-5K8L-18 is binned to the "U2AA" luminous intensity group: "U" = 450–560 mcd (min), "2" = second sub-bin within U, "AA" = 1120–1400 mcd (max). Per the Luminous Intensity Classification table, this means each reel contains LEDs tested and sorted to deliver 560–1400 mcd at 20 mA-ensuring uniform brightness across production batches of VLMW33U2AA-5K8L-18.
