SLC-22DU3F Equivalent & Substitute Parts

Part Overview

The SLC-22DU3F is an orange diffused through-hole LED manufactured by Rohm Semiconductor, designed for indication applications with a dominant wavelength of 605nm and a forward voltage of 2V. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. The part features a 2.00mm diameter round lens with flat top design and is rated at 1.6mcd brightness.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the SLC-22DU3F is determined by the following critical parameters:

• Color: Orange
• Lens Transparency: Diffused
• Lens Size: 2.00mm Diameter
• Voltage - Forward (Vf): 2V
• Mounting Type: Through Hole
• Lens Style: Round with Flat Top

The SSL-LX20483OD-TD from Lumex Opto/Components Inc. qualifies as a substitute based on matching these core parameters. While the substitute part exhibits differences in millicandela rating (20mcd vs. 1.6mcd), wavelength specification (peak 630nm vs. dominant 605nm), current rating (20mA vs. 10mA), viewing angle (70° vs. 115°), and physical height (8.00mm vs. 5.70mm), these variations are within acceptable tolerances for indication LED applications where the primary function is visual signaling rather than precision optical performance.

Parameter Comparison

Engineering Selection Recommendations

The SSL-LX20483OD-TD is suitable as a substitute for the obsolete SLC-22DU3F based on the following factors:

• Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment
• The substitute part is currently in active production status, providing long-term availability and supply chain stability
• Core electrical parameters (2V forward voltage) and mechanical parameters (2.00mm lens diameter, through-hole mounting) are identical
• The increased brightness (20mcd vs. 1.6mcd) and higher test current (20mA vs. 10mA) represent enhanced performance characteristics suitable for indication applications
• Physical height difference (8.00mm vs. 5.70mm) requires PCB layout verification for clearance compatibility

Frequently Asked Questions (FAQ)

Q: Can the SSL-LX20483OD-TD directly replace the SLC-22DU3F in existing designs?

A: Direct replacement is possible if PCB layout accommodates the increased height of 8.00mm. The matching forward voltage (2V) and lens diameter (2.00mm) ensure mechanical and electrical compatibility. Circuit current limiting must accommodate the 20mA test current specification.

Q: What are the key differences between these two parts?

A: The primary differences are brightness (20mcd vs. 1.6mcd), test current (20mA vs. 10mA), viewing angle (70° vs. 115°), and physical height (8.00mm vs. 5.70mm). The wavelength specification differs in format (peak 630nm vs. dominant 605nm) but both represent orange LEDs in the appropriate spectrum.

Q: Why is the SLC-22DU3F classified as obsolete?

A: The SLC-22DU3F is listed as obsolete by Rohm Semiconductor. The SSL-LX20483OD-TD from Lumex provides an active production alternative with equivalent core functionality.

Q: Are there compliance considerations for substitution?

A: Both parts maintain ROHS3 compliance and REACH unaffected status. No additional compliance verification is required for regulatory purposes.

Q: Does the higher brightness of the substitute part affect circuit design?

A: The increased millicandela rating (20mcd) may require circuit current limiting adjustment. Verify that existing current-limiting resistors accommodate the 20mA test current specification to prevent over-driving the substitute part.
