MV8191

LED Indication - Discrete Overview

The MV8191 is a single-color red LED manufactured by onsemi, designed for through-hole mounting in the T-1 3/4 (5 mm) package. It features a diffused dome lens shape with a 45-degree viewing angle and emits light at a wavelength of 660 nm. The component operates with a forward current of 20 mA and a forward voltage of 1.7 V. Packaged in bulk quantities, this discrete indicator LED is currently classified as obsolete and no longer in active production.

LED Indication - Discrete Feature Summary

• Single-color red emission with diffused dome lens design
• Through-hole mounting capability in standard T-1 3/4 package
• Optimized for visual indication applications

LED Indication - Discrete Applications

• Visual status indicators in electronic equipment
• Panel mount signaling devices
• General-purpose illumination in control panels

LED Indication - Discrete Procurement Notes

This component is officially listed as obsolete and no longer manufactured by onsemi. Procurement is restricted to existing stock or secondary market sources. Verify authenticity and condition carefully when sourcing from third-party distributors, as availability is not guaranteed through official channels.

LED Indication - Discrete Selection Notes

Engineers should consider this part only for legacy system maintenance or repair projects requiring exact form-factor compatibility. Due to its obsolete status, new designs must evaluate alternative components that match the required electrical parameters and mechanical dimensions to ensure long-term supply chain stability.

LED Indication - Discrete Part Context

The MV8191 belongs to the discrete LED category within onsemi's historical product portfolio. It serves as a specific variant for red light indication, distinct from multi-color or high-power LED families. Its classification reflects a standard through-hole technology component used in traditional circuit board assembly processes.

LED Indication - Discrete Replacement Considerations

Similar substitutes include parts like 151051RS11000 from Würth Elektronik. Evaluate these alternatives based on matching package size, forward voltage, and luminous intensity requirements to ensure functional equivalence in existing designs.
