Key Parameters

Substitute Part Grouping Explanation

Substitution of the LTL-4223-R1 is determined by the following critical parameters:

• Color and Wavelength: Red indication LEDs with peak wavelength at 635nm
• Lens Configuration: 5mm diffused round domed lens for standard indication applications
• Mounting Type: Through-hole radial package for PCB insertion
• Optical Performance: Millicandela rating and viewing angle suitable for indication purposes
• Physical Dimensions: Maximum height of 8.60mm for standard PCB clearance
• Compliance: EAR99 classification and MSL 1 rating maintained across substitutes

The SSL-LX5093ID-5V qualifies as a direct substitute based on matching lens size, diffused transparency, round domed style, through-hole mounting, radial package, physical height, and red wavelength specification.

Engineering Selection Recommendations

The SSL-LX5093ID-5V is the qualified substitute for the obsolete LTL-4223-R1. Selection is based on:

• Product Status: The SSL-LX5093ID-5V maintains active production status, ensuring long-term availability and supply chain continuity.
• Compliance Alignment: Both parts maintain identical ECCN classification (EAR99) and MSL rating (1 - Unlimited), preserving regulatory and environmental compliance requirements.
• RoHS3 Compliance: The SSL-LX5093ID-5V is RoHS3 compliant, meeting current environmental standards for electronic components.
• Physical and Optical Compatibility: Matching lens size, style, height, and wavelength specification ensure direct PCB-level compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the SSL-LX5093ID-5V directly replace the LTL-4223-R1 in existing designs?

A: Yes. Both parts share identical lens size (5mm), style (round domed), transparency (diffused), mounting type (through-hole radial), maximum height (8.60mm), and peak wavelength (635nm). No PCB layout changes are required.

Q: What are the differences in optical performance between these parts?

A: The SSL-LX5093ID-5V operates at 20mcd with a 60° viewing angle, compared to the LTL-4223-R1 at 29mcd with a 36° viewing angle. The substitute provides wider light distribution with slightly lower intensity. Applications requiring the original 29mcd specification should evaluate whether the 20mcd output meets functional requirements.

Q: Does the SSL-LX5093ID-5V require different forward voltage handling?

A: The SSL-LX5093ID-5V is specified at 5V forward voltage, whereas the LTL-4223-R1 does not provide a typical forward voltage specification. Circuit designs must accommodate the 5V specification of the substitute part.

Q: Are there packaging differences between these parts?

A: The LTL-4223-R1 is supplied in standard packaging, while the SSL-LX5093ID-5V is supplied in bulk packaging. Both maintain identical MSL 1 (Unlimited) moisture sensitivity ratings.

Q: What compliance certifications apply to the SSL-LX5093ID-5V?

A: The SSL-LX5093ID-5V is RoHS3 compliant and REACH unaffected. Both parts maintain EAR99 export classification and MSL 1 rating.
