IN-S128DAT5R5B

LED Indication - Discrete Overview

The IN-S128DAT5R5B is a dual-chip bi-color surface-mount LED manufactured by Inolux, housed in a 1210 (3.2mm x 2.7mm) package with a rectangular lens featuring a dome style. It integrates red and blue emitters in a common anode configuration. The device operates at a forward current of 5mA for both colors, with typical forward voltages of 2.2V to 2.6V for the red segment and 3.2V to 3.6V for the blue segment. Peak wavelengths are specified at 625nm for red and 470nm for blue. Luminous intensity ratings are 56mcd for red and 72mcd for blue. The component offers a wide viewing angle of 130 degrees and is designed for right-angle surface mounting.

LED Indication - Discrete Feature Summary

• Dual-emitter construction combining red and blue light sources within a single compact SMD footprint
• Common anode electrical topology simplifying circuit design for bi-color indication applications
• Rectangular lens geometry with a dome profile providing a standardized 130-degree viewing angle

LED Indication - Discrete Applications

• Status indication on industrial control panels and automation equipment
• Bi-color signaling for electronic devices requiring distinct visual alerts
• Front panel indicators for consumer electronics and instrumentation

LED Indication - Discrete Procurement Notes

Verify the specific voltage binning requirements against your circuit design, as forward voltage ranges vary between the red and blue segments. Confirm that the 1210 package dimensions align with your PCB footprint constraints. Ensure compatibility with standard reflow soldering profiles suitable for moisture sensitivity level 3 components. Cross-reference the common anode pinout with your schematic to prevent polarity errors during assembly.

LED Indication - Discrete Selection Notes

Select this component when a compact bi-color indicator is required for space-constrained designs. The 1210 form factor provides a balance between visibility and board real estate. Consider the specific luminous intensity requirements, noting the difference between red and blue output levels. Verify that the operating temperature range meets the environmental conditions of the intended application.

LED Indication - Discrete Part Context

This part belongs to Inolux's IN-S121 series of bi-color LEDs, which are engineered for high-reliability surface-mount applications. The series utilizes advanced semiconductor materials to achieve stable color performance. Similar parts in the lineup may offer different lens shapes or mounting orientations, but share comparable electrical characteristics and packaging standards for consistent manufacturing processes.

LED Indication - Discrete Replacement Considerations

Direct substitutes include other 1210 bi-color LEDs with matching common anode configurations and similar forward voltage specifications. Verify mechanical compatibility by comparing the 3.2mm x 2.7mm outline and height limits. Electrical equivalence requires checking peak wavelength and luminous intensity tolerances to ensure consistent visual output in the final assembly.
