Key Features
- Dual independent yellow LED elements in a single radial package, reducing component count in multi-indicator designs
- 6.3 mcd nominal luminous intensity ensuring clear visibility in indoor industrial panel environments
- 20mA maximum forward current compatible with standard TTL and CMOS GPIO drive levels with current-limiting resistors
- Radial through-hole mounting enabling secure installation in front-panel PCBs and indicator housings
- RoHS compliant (JESD-609 e1) for lead-free industrial and commercial equipment manufacturing
Applications
Dialight 553-0133F is suited for dual-channel status indication on industrial control panels, relay modules, and programmable logic controllers where two independent yellow LED indicators are required in a compact single-package solution. Its radial through-hole package provides mechanical robustness for front-panel PCB installations subject to vibration in factory automation environments. Test and measurement instruments, telecommunications equipment, and power distribution units also use this LED array for alarm and activity indication where yellow signifies caution or standby states.

Frequently Asked Questions
How are the two LED elements in Dialight 553-0133F configured, and can they be driven independently?
Dialight 553-0133F uses a separate 2-element configuration, meaning each yellow LED has its own anode and cathode pins and can be driven independently by separate GPIO or driver outputs. This allows one element to indicate a fault condition while the other shows normal operation simultaneously, supporting dual-state status displays without additional components. Maximum forward current for each element is 20mA.
What luminous intensity does Dialight 553-0133F provide, and is it bright enough for well-lit industrial panel environments?
Dialight 553-0133F has a nominal luminous intensity of 6.3 mcd at rated forward current. This level is adequate for indoor industrial control panels and equipment bays with typical ambient illumination below 1000 lux, where yellow indicator LEDs at 6 mcd to 10 mcd are clearly visible to operators at distances of 0.5m to 1m. For brighter outdoor or high-ambient environments, a higher-intensity LED array would be required.
What resistor value is needed to drive Dialight 553-0133F from a 5V logic output at 10mA per element?
Assuming a typical yellow LED forward voltage of approximately 2.1V, the current-limiting resistor for each element when driven from a 5V supply at 10mA is calculated as (5V - 2.1V) / 10mA = 290 ohms. A standard 270 ohm or 300 ohm resistor would set the current close to 10mA, well within the 20mA maximum forward current rating and providing adequate brightness for panel indicator use.
