MT7315B-UR-A

LED Indication - Discrete Overview

The MT7315B-UR-A is a single-color visible emitter manufactured by Marktech Optoelectronics. It operates at a peak wavelength of 660nm and a dominant wavelength of 643nm, emitting red light. The component features a forward voltage of 1.9V and a power rating of 72mW. It utilizes a 5mm round radial package with a water-clear dome lens. The viewing angle is specified at 20 degrees.

LED Indication - Discrete Feature Summary

• Produces visible red light emission
• Utilizes a water-clear dome lens for optical clarity
• Designed for through-hole radial mounting

LED Indication - Discrete Applications

• General purpose indicator lighting
• Electronic status signaling
• Panel instrumentation displays

LED Indication - Discrete Procurement Notes

Verify the specific datasheet version before integration, as manufacturer documentation may contain updated electrical tolerances or mechanical dimensions. Confirm that the radial lead configuration matches the target PCB footprint requirements. Ensure the operating current does not exceed the rated limits to maintain device longevity and consistent optical output performance.

LED Indication - Discrete Selection Notes

Select this component when a standard 5mm through-hole red LED is required for visual indication applications. The 20-degree viewing angle provides a focused beam suitable for direct line-of-sight visibility. Consider the 1.9V forward voltage drop when designing the series current-limiting resistor network to ensure proper biasing within the circuit constraints.

LED Indication - Discrete Part Context

This part belongs to the T-1 (3mm) LED lamp family from Marktech Optoelectronics. While similar in function to other red emitters, it is distinguished by its specific 5mm round radial form factor and clear lens construction. It serves as a discrete component for basic electronic assembly needs requiring reliable visible light output.

LED Indication - Discrete Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing designs by matching the radial package dimensions and electrical characteristics against alternative suppliers' offerings.
