MV5491A

LED Indication - Discrete Overview

The MV5491A is a dual-color LED circuit board indicator manufactured by Everlight. It features a T-1 3/4 (5 mm) radial package with a diffused white lens, providing a 100-degree viewing angle. The component utilizes a common bipolar terminal configuration for red and green elements. Key electrical parameters include a peak wavelength of 660 nm for red and 565 nm for green, with a nominal light intensity of 6 mcd. The forward voltage is specified at 2.3 V, and the device operates within a temperature range of -55°C to +100°C.

LED Indication - Discrete Feature Summary

• Dual-color functionality combining red and green emission in a single radial package
• Common bipolar terminal configuration for independent color control
• Diffused white lens design ensuring a wide 100-degree viewing angle

LED Indication - Discrete Applications

• Board status indication in electronic assemblies
• Power supply status monitoring
• Signal verification in industrial control panels

LED Indication - Discrete Procurement Notes

Verify the specific suffix code (e.g., MP7, MP91) as it determines packaging and reel specifications. Confirm RoHS compliance status through official documentation before integration. Check current lifecycle status as availability may be limited due to end-of-life classifications. Ensure pinout compatibility with existing PCB footprints during replacement planning.

LED Indication - Discrete Selection Notes

Select this component when a compact dual-color indicator is required for space-constrained designs. The T-1 3/4 form factor offers a balance between visibility and board real estate. Consider the common bipolar configuration if independent control of red and green states is necessary without complex multiplexing circuits.

LED Indication - Discrete Part Context

This part belongs to Everlight's line of through-hole LED indicators. It serves as a visual signaling component for various electronic devices. The T-1 3/4 size is a standard industry format for general-purpose indication applications.

LED Indication - Discrete Replacement Considerations

Direct substitutes include MV54919MP7 and MV54919MP91 from the same manufacturer family. Verify that alternative parts match the T-1 3/4 package dimensions and common bipolar pinout configuration.
