Description / 0603 SMD Cool / Clear White - Ultra Bright LED

The 0603 Cool White SMD LED (1.6 × 0.8mm, metric 1608) is the most widely used SMD indicator size in both hobbyist and production PCB work — small enough for tight layouts, large enough to hand-solder reliably with flux and a fine-tip iron.

Package0603 (1608 metric) — SMD surface mount
Forward Voltage3.0-3.2v
Brightness550mcd
Viewing Angle120 Degrees
LensDiffused
Drive Current20mA typical

Hand-solderable with a fine-tip iron and flux paste. Easier than 0402, still small enough for tight decoder and PCB layouts.

Common uses:

  • Gaming console repair — Xbox 360/One, PS3/PS4, Wii, and Game Boy indicator LED replacement (iFixit community)
  • Guitar pedal builds — Boss 2017+ models and modern stompbox PCBs use 0603 indicator LEDs (Freestompboxes, PedalPCB)
  • Mechanical keyboard backlight repair — per-key indicator LEDs on custom PCBs (r/MechanicalKeyboards, Geekhack)
  • N scale and HO scale DCC decoder lighting — headlights, interior lights, and function outputs
  • Custom PCB indicators for ESP32/RP2040 projects, breakout boards, and open-source hardware designs

*Use 15V instead of 12V for vehicle/alternator sources to account for charging voltage (13.8–14.4V).

DC power recommended: LEDs are designed for DC. Running on AC will cause flickering and reduce lifespan. If you're using a low-voltage AC source — such as a model railroad transformer output or DCC track voltage — convert it to DC first with a bridge rectifier.
