LTL-4223-R2 Equivalent & Substitute Parts

Part Overview

The LTL-4223-R2 is a red diffused through-hole LED manufactured by Lite-On Inc., designed for indication applications with a dominant wavelength of 623nm and peak wavelength of 635nm. This component is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing design support and procurement continuity. The 5mm round domed lens configuration with 29mcd brightness rating and 36° viewing angle defines its application scope in standard LED indication circuits.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LTL-4223-R2 is determined by the following critical parameters:

• Color and Wavelength: Red spectrum (dominant 623nm, peak 635nm) for visual indication compatibility
• Lens Configuration: 5mm diffused round domed lens for optical consistency and form factor
• Mounting Type: Through-hole radial package for PCB compatibility
• Physical Dimensions: Maximum height of 8.60mm for mechanical fit
• Optical Characteristics: Viewing angle and brightness rating (29mcd) for application visibility requirements
• Environmental Rating: MSL 1 (Unlimited) for standard storage and handling conditions

The SSL-LX5093ID-12V qualifies as a substitute based on matching color, lens type, lens size, mounting configuration, height, and environmental specifications. Differences in forward voltage (12V vs. unspecified for main part), millicandela rating (20mcd vs. 29mcd), and viewing angle (60° vs. 36°) represent functional variations that must be evaluated within specific circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

The SSL-LX5093ID-12V is an active production substitute for the obsolete LTL-4223-R2. Both components share identical export classification (EAR99) and tariff codes (8541.41.0000), confirming regulatory equivalence. The SSL-LX5093ID-12V carries RoHS3 compliance and REACH unaffected status, meeting modern environmental standards.

Selection of the SSL-LX5093ID-12V requires circuit-level evaluation of the following differences:

• Forward Voltage: The substitute specifies 12V operation, whereas the main part forward voltage is not provided. Circuit design must accommodate this voltage requirement.
• Brightness: The substitute provides 20mcd versus 29mcd for the original, representing a 31% reduction in luminous intensity.
• Viewing Angle: The substitute offers 60° versus 36°, providing wider light distribution.

Both components maintain identical physical dimensions (8.60mm maximum height) and mounting configuration, ensuring mechanical interchangeability in through-hole applications.

Frequently Asked Questions (FAQ)

Q: Can the SSL-LX5093ID-12V directly replace the LTL-4223-R2 in existing designs?

A: Mechanical and optical form factors are compatible. However, the 12V forward voltage specification of the substitute requires verification against the original circuit design. If the original circuit was designed for a different forward voltage, current-limiting resistor values must be recalculated.

Q: What is the significance of the 9mcd brightness difference?

A: The SSL-LX5093ID-12V provides 20mcd compared to the original 29mcd. This 31% reduction in luminous intensity may affect visibility in high-ambient-light applications. Circuit design must confirm that 20mcd brightness meets application requirements.

Q: How do the viewing angles differ functionally?

A: The SSL-LX5093ID-12V offers a 60° viewing angle versus 36° for the original. The wider angle provides visibility across a broader range of observer positions, which may be advantageous or disadvantageous depending on the intended application geometry.

Q: Are both components RoHS compliant?

A: The SSL-LX5093ID-12V is explicitly RoHS3 compliant. The LTL-4223-R2 RoHS status is not specified in the provided data.

Q: What packaging options are available?

A: The LTL-4223-R2 is available in standard packaging. The SSL-LX5093ID-12V is supplied in bulk packaging (T-1 3/4 supplier device package).

Q: Are there inventory considerations for procurement?

A: The LTL-4223-R2 has 927 pieces in stock as new original inventory. The SSL-LX5093ID-12V has 1744 pieces available, providing greater procurement flexibility for active production designs.
