5UWC-0.8K

Part Overview

The 5UWC-0.8K is a white LED indication component manufactured by Bivar Inc., featuring a clear T-1 3/4 (5mm) through-hole package. This discrete 3.5V radial LED is classified as obsolete. Finding equivalent and substitute parts is necessary to maintain design continuity and support existing applications where this component is no longer in active production.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5UWC-0.8K must maintain compatibility across the following key parameters:

• Color and Lens Properties: White color with clear, domed-top lens for consistent visual appearance and light transmission characteristics
• Package and Mounting: T-1 3/4 (5mm) through-hole radial configuration for mechanical fit and PCB compatibility
• Electrical Parameters: Forward voltage (Vf) tolerance range of 3.5V to 3.6V and test current specifications to ensure proper circuit operation
• Optical Performance: Luminous intensity (millicandela rating) and viewing angle to meet application visibility requirements
• Reliability: MSL rating of 1 (Unlimited) for moisture sensitivity and compliance certifications

The SSL-LX5093UWC/A from Lumex Opto/Components Inc. qualifies as a substitute within these parameters while offering active product status.

Engineering Selection Recommendations

The SSL-LX5093UWC/A is a qualified substitute for the obsolete 5UWC-0.8K. Key considerations:

• Product Status: The SSL-LX5093UWC/A is active in production, providing supply continuity where the original part is obsolete.
• Compliance: ROHS3 compliance and REACH unaffected status are documented for the substitute part.
• Parameter Tolerance: Forward voltage differs by 0.1V (3.5V to 3.6V), within acceptable operating range for most applications. Test current is lower at 20mA compared to 30mA.
• Optical Performance: Millicandela rating is 60mcd lower (740mcd vs. 800mcd), while viewing angle is wider (45° vs. 25°), affecting brightness distribution characteristics.
• Physical Compatibility: Height is slightly lower (8.60mm vs. 8.80mm) with identical lens size and package type, maintaining through-hole mounting compatibility.

Frequently Asked Questions (FAQ)

Q: Can SSL-LX5093UWC/A directly replace 5UWC-0.8K in all applications? A: Direct replacement is appropriate where the 0.1V forward voltage difference and lower test current (20mA vs. 30mA) are acceptable in the circuit design. The 60mcd brightness difference and wider 45° viewing angle alter light distribution; applications sensitive to specific brightness or directional output require engineering verification.

Q: Why does the substitute have a lower millicandela rating? A: The SSL-LX5093UWC/A exhibits 740mcd output compared to the original 800mcd. This parameter difference is documented from the manufacturer specifications and represents the available substitute within the T-1 3/4 white LED category.

Q: Are there packaging differences between the two parts? A: Both parts use identical T-1 3/4 (5mm) radial through-hole packages. The substitute's maximum height of 8.60mm is 0.20mm lower than the original 8.80mm, which does not impact PCB clearance in standard through-hole designs.

Q: What compliance certifications apply to the substitute? A: The SSL-LX5093UWC/A is ROHS3 compliant and REACH unaffected. Both parts share the same EAR99 export classification and HTSUS code (8541.41.0000).

Q: How does the wider viewing angle affect circuit behavior? A: The SSL-LX5093UWC/A provides a 45° viewing angle compared to the original 25°. This results in wider light distribution with the same brightness rating, affecting the visibility pattern across different viewing positions. Application-specific requirements determine whether this characteristic change is acceptable.
