Equivalent & Alternatives
The following parts are listed as comparable options for similar soft orange LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VLMK333U2AB-GS08 | Orange red (611–622 nm), slightly higher min. dominant wavelength; identical package, drive, and thermal specs | Better suited for applications requiring warmer red-orange tone (e.g., brake light simulation), less ideal for soft amber signaling | Select VLMO333U2AB-GS18 when chromaticity must meet soft orange CIE coordinates; choose VLMK333U2AB-GS08 for higher-wavelength orange-red emphasis |
| LO T67F-U2AB-24-1 (OSRAM) | Same dominant wavelength range (600–611 nm), PLCC-2 package, but lower max. luminous intensity (1400 mcd vs. 1800 mcd) | Valid alternative where brightness headroom is not critical; differs in moisture sensitivity level (MSL 3 vs. level 2a) | Use LO T67F-U2AB-24-1 only if supply chain diversification is prioritized over maximum intensity margin and MSL 2a handling requirements |
Compared with VLMK333U2AB-GS08 and LO T67F-U2AB-24-1, VLMO333U2AB-GS18 offers the highest luminous intensity ceiling (1800 mcd) within its soft orange bin and the strictest moisture handling protocol (JEDEC level 2a), making it optimal for high-reliability automotive and industrial indicator designs where brightness consistency and assembly robustness are critical.

FAQ
What is the maximum continuous forward current for VLMO333U2AB-GS18?
The VLMO333U2AB-GS18 supports a maximum DC forward current of 50 mA when ambient temperature is ≤73 °C and mounted on a PCB with thermal pad area >16 mm². Exceeding this limit without adequate heat sinking risks junction temperature exceeding 125 °C and accelerated lumen depreciation. Derating is required above 73 °C per Figure 1 in the datasheet.
Is VLMO333U2AB-GS18 suitable for automotive applications?
Yes, VLMO333U2AB-GS18 is AEC-Q101 qualified and rated for operating temperatures from –40 to +100 °C, making it suitable for dashboard illumination, interior status indicators, and exterior signaling in passenger vehicles and commercial transport. Its 2 kV HBM ESD rating and JEDEC level 2a moisture sensitivity also align with automotive manufacturing requirements.
What does the "GS18" suffix mean in VLMO333U2AB-GS18?
The "GS18" suffix indicates an 8 mm antistatic blister tape packaging option containing 8000 pieces per reel - the preferred large-volume configuration. It follows DIN IEC 40 (CO) 564 standards and includes EIA JEDEC level 2a moisture-sensitive labeling. This differs from GS08 (1500 pcs/reel) and confirms dry-pack handling requirements.
How is luminous intensity binned for VLMO333U2AB-GS18?
VLMO333U2AB-GS18 is intensity-binned per packing unit with IVmax/IVmin ≤ 1.6, meaning the brightest and dimmest units on a single reel differ by no more than 60%. Each reel ships with only one intensity group (e.g., Group B: 1400–1800 mcd), ensuring consistent brightness across assemblies without post-production sorting.
Can VLMO333U2AB-GS18 be soldered using standard reflow profiles?
Yes, VLMO333U2AB-GS18 is qualified for lead-free reflow soldering per J-STD-020, with a maximum peak temperature of 260 °C for ≤100 s. The recommended profile includes ramp-up ≤3 °C/s, time above 217 °C ≤30 s, and cooling rate ≤6 °C/s. It is also compatible with vapor-phase and wave-solder processes per CECC 00802.
