VLMR333U1AA-GS18

LED Indication - Discrete Overview

The VLMR333U1AA-GS18 is a single-color red LED from the Vishay VLMx series, designed for surface-mount applications. It features a PLCC-2 package with dimensions of 3 mm in length, 2.8 mm in width, and 1.75 mm in height. The component emits light at a peak wavelength of 625 nm with a viewing angle of 120 degrees. Key electrical parameters include a forward voltage of 2 V at a test current of 20 mA, resulting in a power rating of 130 mW. The optical intensity is specified at 750 mcd. The lens is colorless, non-diffused, and round flat, suitable for standard indication tasks.

LED Indication - Discrete Feature Summary

• Surface-mount design utilizing a compact PLCC-2 package for automated assembly integration.
• High-intensity red emission optimized for visual status indication applications.
• Non-diffused clear lens construction providing focused directional light output.

LED Indication - Discrete Applications

• Panel status indicators
• Equipment front-panel signaling
• Consumer electronics status lights

LED Indication - Discrete Procurement Notes

This component is officially listed as obsolete by the manufacturer and is no longer in active production. Verification of availability should focus on surplus distributors or secondary market sources rather than direct factory orders. Buyers must confirm the specific manufacturing date code and storage history due to potential moisture sensitivity degradation over time. Replacement strategies should prioritize equivalent new-generation components to ensure long-term supply chain stability.

LED Indication - Discrete Selection Notes

Engineers selecting this part should note its discontinued status and plan for lifecycle management. The PLCC-2 form factor requires compatible PCB footprints matching the 3 mm x 2.8 mm outline. Electrical compatibility involves verifying that circuit designs support the 2 V forward voltage drop at 20 mA. Thermal management remains within standard limits given the 130 mW power rating, but ambient operating temperatures must stay within the -40 C to +100 C range specified for reliable operation.

LED Indication - Discrete Part Context

The VLMR333U1AA-GS18 belongs to the VLMx family of surface-mount LEDs manufactured by Vishay Semiconductor Opto Division. This series is characterized by small footprint packages designed for high-density mounting on printed circuit boards. The product line typically includes various colors and intensities, with the red variant offering standard visibility for general-purpose indication.
