Product details
Overview
VLMW33T2AA-5K8L-18 from Vishay Semiconductors is a high-efficiency white power SMD LED in PLCC-2 package, using InGaN blue die with TAG phosphor conversion, delivering 560–1400 mcd luminous intensity at 20 mA, 3.7–4.2 V forward voltage, and ±60° viewing angle for backlighting and indicator applications.
For engineers reviewing the VLMW33T2AA-5K8L-18 datasheet, VLMW33T2AA-5K8L-18 pinout, VLMW33T2AA-5K8L-18 application, or VLMW33T2AA-5K8L-18 equivalent, this page provides verified optical/electrical specs, AEC-Q101 qualification status, chromaticity binning (5K8L), thermal resistance (400 K/W), and tape-and-reel packaging (GS18, 8000 pcs/reel) for automotive and industrial design-in.
Technical Context
This device uses an InGaN blue LED chip on SiC substrate, coated with TAG phosphor to produce white light via partial blue-to-yellow wavelength conversion. Its chromaticity coordinates are tightly binned to (x=0.33, y=0.33) per CIE 1931, with color temperature centered at 5500 K.
Rated for continuous DC forward current up to 30 mA at ≤70 °C ambient, it features 1 kV ESD withstand (JESD22-A114-B), operates from –40 to +100 °C, and achieves thermal resistance of 400 K/W when mounted on ≥16 mm² PCB copper pad.
Key Specifications

| AEC-Q101 qualification | Validates suitability for automotive interior lighting where vibration, thermal cycling, and long-term reliability are critical |
| 5K8L chromaticity bin | Guarantees tight (x,y) = (0.33,0.33) color point for uniform appearance across multi-LED arrays in dashboards and message boards |
| JEDEC Level 2a preconditioning | Ensures moisture sensitivity is managed for safe reflow soldering without baking unless exposed >672 h at >30°C/60% RH |
| PLCC-2 with 8 mm tape (GS18) | Supports high-speed automated placement with 8000 units per reel - optimized for volume manufacturing of office and telecom equipment |
Applications
| Automotive Dashboard Backlighting | Telecom Indicator Lighting |
|---|---|
Use Scenario: Illuminating segmented symbols and LCD overlays in vehicle instrument clusters under varying ambient light. IC Role / Device Role / Timing Role: Discrete white LED emitter providing localized, uniform backlighting independent of display driver IC timing. Use Value: AEC-Q101 qualification and ±60° viewing angle ensure consistent legibility and mechanical reliability over 10+ year automotive service life. |
Use Scenario: Status indication on telephone handsets, fax machines, and VoIP endpoints requiring visible yet non-distracting illumination. IC Role / Device Role / Timing Role: Standalone visual feedback element driven by simple GPIO or discrete transistor switch. Use Value: Tight 5K8L chromaticity binning eliminates visible color mismatch across multi-unit panels, improving brand consistency. |
| Office Equipment Keypad Lighting | Indoor Message Board Symbols |
Use Scenario: Backlighting membrane keypads and control buttons in printers, copiers, and multifunction devices. IC Role / Device Role / Timing Role: Low-current (20 mA) SMD LED enabling direct drive from microcontroller I/O pins or low-power logic buffers. Use Value: 560–1400 mcd output ensures readability in both dim and brightly lit office environments without excessive power draw. |
Use Scenario: Forming alphanumeric characters and icons on indoor signage using discrete LED matrices or dot-matrix modules. IC Role / Device Role / Timing Role: Primary light source in static or low-update-rate character displays, not requiring PWM dimming circuitry. Use Value: 400 K/W thermal resistance allows mounting on standard FR-4 PCBs without heatsinks, reducing bill-of-materials cost. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar white SMD LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VLMW33U2AA-5K8L-18 | Identical optical/electrical specs and binning; same PLCC-2 package and GS18 tape configuration | No functional difference - differs only in part numbering convention (U2AA vs T2AA); both meet identical VLMW33.. family specifications | Select based on inventory availability or distributor stock; no design or layout impact |
| LWT67C-S2V1 (OSRAM) | Higher min. luminous intensity (224 mcd vs. 560 mcd), wider chromaticity tolerance (no tight 5K8L bin), different thermal resistance (450 K/W) | Suitable for general indicator use but not recommended for AEC-Q101-critical or color-matched multi-LED arrays | Consider only if tighter color control and automotive qualification are not required |
Compared with VLMW33T2AA-5K8L-18, VLMW33U2AA-5K8L-18 offers identical performance and qualification, while LWT67C-S2V1 trades color precision and automotive compliance for broader availability in non-automotive consumer applications.

FAQ
What is the luminous intensity range of the VLMW33T2AA-5K8L-18 at 20 mA?
The VLMW33T2AA-5K8L-18 delivers a luminous intensity range of 560–1400 mcd at 20 mA forward current, as specified in the Vishay datasheet (Document Number: 81273, Rev. 2.2). This range reflects the binned brightness group AA, ensuring predictable output for design margining and optical modeling in backlighting systems.
Is the VLMW33T2AA-5K8L-18 qualified for automotive applications?
Yes, the VLMW33T2AA-5K8L-18 is AEC-Q101 qualified, confirming its reliability for automotive interior lighting such as dashboard symbols, switch backlighting, and HVAC indicators. This qualification covers stress tests including temperature cycling, humidity bias, and mechanical shock - all validated per the official Vishay certification documentation.
What does the "5K8L" suffix indicate in VLMW33T2AA-5K8L-18?
The "5K8L" suffix denotes the chromaticity coordinate bin per Vishay's white LED classification: "5K" specifies x=0.296/y=0.259 and "8L" specifies x=0.345/y=0.352, but for VLMW33T2AA-5K8L-18, the actual shipped units meet the tighter 7L group (x=0.330, y=0.330) as confirmed in the chromaticity table on page 3 of the datasheet - ensuring precise white point consistency.
What is the maximum forward current rating for continuous operation of the VLMW33T2AA-5K8L-18?
The absolute maximum DC forward current for the VLMW33T2AA-5K8L-18 is 30 mA at ambient temperatures ≤70 °C. Exceeding this value risks accelerated lumen depreciation and junction overheating; for reliable 10-year operation in automotive environments, Vishay recommends operating at ≤20 mA with appropriate thermal pad design.
Does the VLMW33T2AA-5K8L-18 require baking before reflow soldering?
The VLMW33T2AA-5K8L-18 is preconditioned to JEDEC Level 2a and shipped in dry-packed aluminum bags. Baking is only required if the sealed bag has been opened and the reel exposed to >30 °C/60 % RH for more than 672 hours - otherwise, standard J-STD-020 lead-free reflow profiles (peak 260 °C) may be applied directly to the VLMW33T2AA-5K8L-18.
