CL-196HR-CD

Overview

The CL-196HR-CD is a single-color red light-emitting diode manufactured by Citizen. It utilizes an ultra-small package with dimensions of 1.60 mm in length, 0.80 mm in width, and a height of 0.60 mm. The device features a non-diffused lens and operates within a temperature range of -25 °C to +80 °C. Key electrical parameters include a maximum forward current of 20 mA and a peak wavelength of 700 nm. The nominal luminous intensity is specified at 1.3 mcd. This component is designed for surface mount installation and is compatible with the CL-191 series.

Feature Summary

• Ultra-small chip LED design with reduced thickness compared to previous generations
• Single-color emission configuration optimized for compact applications
• Compatible form factor with the CL-191 series for design flexibility

Applications

• Indicator lights in portable electronic devices
• Status indication in compact instrumentation
• Backlighting or signaling in space-constrained consumer electronics

Procurement Notes

Verify the specific suffix 'HR' against official documentation to confirm high-reliability or radiation-hardened specifications if applicable, as standard datasheets may list general series characteristics. Ensure the ordering code matches the exact lens type and binning requirements for your application. Cross-reference the manufacturer's latest revision notes to confirm compliance with current environmental directives and material declarations before finalizing procurement.

Selection Notes

Select this component when board space is limited due to its 0.60 mm height profile. Consider the 700 nm peak wavelength for visibility requirements in red signaling applications. Verify thermal management capabilities given the 80 °C maximum operating temperature limit. Ensure the driving circuit supports the 20 mA maximum forward current rating without exceeding power dissipation limits defined in the absolute maximum ratings.

Part Context

This part belongs to the CL-196 series of ultra-small chip LEDs from Citizen. The series is characterized by its reduced thickness relative to the CL-190 model, offering a compact solution for modern electronics. The CL-196 series maintains compatibility with the CL-191 series footprint, facilitating easier design transitions or replacements in existing layouts while providing enhanced miniaturization benefits.

Replacement Considerations

The CL-196R-T is documented as compatible with the CL-191 series, similar to the CL-196HR-CD. Verify dimensional and electrical equivalence between these variants before substitution. Check for any differences in lens type or reliability ratings that might affect performance in specific environments.
