LED Indication - Discrete datasheet and documents for HLMPM301
LED Indication - Discrete Overview
The HLMPM301 is a single-color yellow LED from onsemi, designed for through-hole mounting in a T-1 3/4 (5 mm) package. It features a diffused dome lens and emits light at a wavelength of approximately 590 nm. The component operates with a forward voltage of 2.2 V and supports a maximum forward current of 30 mA. It provides a viewing angle of 135 degrees, ensuring wide visibility for indicator applications.
LED Indication - Discrete Feature Summary
- Yellow emission with diffused dome lens
- Through-hole radial mounting style
- Wide 135-degree viewing angle
LED Indication - Discrete Applications
- Panel status indicators
- Equipment power indicators
- Control board signaling
LED Indication - Discrete Procurement Notes
Verify the HLMPM301 lifecycle status as discontinued or obsolescence before procurement planning. Confirm that the specific through-hole package dimensions align with existing PCB footprints. Check for valid replacement part numbers if new production is required. Ensure supply chain sources are authorized to avoid counterfeit components.
LED Indication - Discrete Selection Notes
Select this component when a standard 5mm through-hole yellow LED is required for general indication. The 135-degree viewing angle suits applications needing broad visibility. Verify that the 2.2V forward voltage matches the circuit design constraints. Consider the discontinued status when designing long-term products.
LED Indication - Discrete Part Context
The HLMPM301 belongs to the discrete LED indication category from onsemi. It is a legacy product previously associated with Fairchild Semiconductor. The component serves as a standard indicator element in electronic assemblies where visual status feedback is necessary.
LED Indication - Discrete Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Due to the discontinued status, verify equivalent specifications with other manufacturers if replacement is necessary.
