2. How SMD LED Model Numbers Work
SMD LED model numbers are named after the package dimensions: length × width in hundredths of an inch:
-
0603 = 0.06 in × 0.03 in = 1.6mm × 0.8mm
-
0805 = 0.08 in × 0.05 in = 2.0mm × 1.25mm
-
1206 = 0.12 in × 0.06 in = 3.2mm × 1.6mm
💡 Memory tip: the first two digits are the length (in 0.01 in), the last two are the width (in 0.01 in).
3. Parameter Comparison by LED Color

4. FAQ
Q1: Is the power rating in the cross-reference table fixed?
A: No. LED power scales with drive current. A 0603 at its standard 20mA draws about 0.06W; at 10mA it drops to 0.03W. Over-driving increases power but accelerates lumen depreciation.
Q2: Which is brighter, the 5730 or the 2835?
A: At the same current, the 5730 is usually brighter than the 2835 because of its larger emitting area. However, a 2835 can reach higher brightness at higher current (e.g., 1W drive). Always compare the luminous flux (lm) figures in the datasheet.
Q3: Can a 5050 package be made in white?
A: Yes. The 5050 holds three chips: all three can be white chips (high-brightness white 5050), or one red + one green + one blue for RGB full color. A white 5050 is usually brighter than a single 2835, though its efficacy is slightly lower.
