3BC-R/Y

LED Indication - Discrete Overview

The Bivar Inc. 3BC-R/Y is a standard 3mm (T1) through-hole bi-color LED featuring a white diffused lens with a round domed top. It emits red light at 625nm and yellow light at 590nm, offering a 45-degree viewing angle. The component has a maximum height of 4.50mm and supports bidirectional configuration. Typical forward voltage is 2V for both colors, with a forward current of 20mA. Luminous intensity is rated at 6 mcd for red and 4 mcd for yellow. This RoHS compliant device is designed for reliable power indication in electronic assemblies.

LED Indication - Discrete Feature Summary

• Bi-color functionality providing distinct red and yellow illumination within a single 3mm package
• White diffused lens design ensuring uniform light distribution and visibility
• Bidirectional configuration capability for flexible circuit board mounting orientations

LED Indication - Discrete Applications

• Power status indication on electronic control panels
• Signal indication in industrial instrumentation
• Visual feedback components in consumer appliance interfaces

LED Indication - Discrete Procurement Notes

Verify the specific ordering suffix when sourcing this component, as variants such as the flange style (3BC-R/Y-F) exist. Confirm availability status carefully, as certain configurations like the 3BC-3-R/Y are listed as obsolete by major distributors. Ensure the selected part matches the required lead angle and package dimensions for your PCB layout constraints.

LED Indication - Discrete Selection Notes

Select this component when a compact 3mm bi-color indicator is required for space-constrained designs. Consider the bidirectional nature if assembly orientation flexibility is needed. Verify that the 20mA forward current rating aligns with your driver circuit capabilities. Check for the specific lens style and lead configuration required for your mechanical housing or panel mount application.

LED Indication - Discrete Part Context

This part belongs to Bivar's standard 3mm T1 series of discrete LED indicators. It shares the physical footprint and electrical characteristics with other variants in the family, differing primarily in color combinations and optional mechanical features like flanges. It serves as a fundamental component for visual signaling in general-purpose electronics where dual-state indication is necessary.

LED Indication - Discrete Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Note that the 3BC-3-R/Y variant is explicitly marked as obsolete. Cross-reference with other 3mm bi-color LEDs only after verifying exact pinout, luminous intensity, and voltage requirements match the original design specifications.
