5UYC-2K

Part Overview

The 5UYC-2K is a yellow LED indicator light manufactured by Bivar Inc., designed for through-hole mounting applications. This part is classified as obsolete, necessitating identification of suitable alternatives from the active product portfolio to ensure continued design support and component availability.

Key Parameters

Substitute Part Grouping Explanation

The 5YD has been identified as a substitute for the obsolete 5UYC-2K based on the following shared electrical and mechanical parameters:

Common Attributes:

• Identical manufacturer (Bivar Inc.)
• Same color specification (Yellow)
• Same lens size (5mm, T-1 3/4)
• Same mounting type (Through Hole)
• Identical peak wavelength (590nm)
• Identical package type (Radial)
• Same moisture sensitivity level (MSL 1 - Unlimited)

Allowed Substitution Parameters: The 5YD operates at slightly higher forward voltage (2V vs. 1.9V) and lower test current (20mA vs. 30mA). The diffused lens transparency and reduced millicandela rating (25mcd vs. 2000mcd) represent significant operational differences but do not preclude use as a substitute where the application tolerates these lower brightness characteristics and diffused light distribution.

Parameter Comparison

Engineering Selection Recommendations

The 5YD is an active product offering from Bivar Inc. and provides design continuity for applications requiring through-hole mounted, yellow-emitting LEDs in the T-1 3/4 form factor. Both parts maintain identical moisture sensitivity levels and identical compliance certifications (EAR99, HTSUS 8541.41.0000).

Selection of the 5YD as a substitute requires verification that the application can accommodate the operational differences: lower brightness output (25mcd vs. 2000mcd), diffused lens characteristics, marginally higher forward voltage (0.1V increase), and reduced test current (10mA decrease). The wider viewing angle (45° vs. 30°) of the 5YD may be advantageous for applications requiring broader light distribution.

Frequently Asked Questions (FAQ)

Q: Can the 5YD be used as a direct replacement for the 5UYC-2K?

A: Electrical compatibility is confirmed by shared wavelength (590nm), identical forward voltage tolerance, and compatible current ratings. Mechanical compatibility is verified by identical lens size (5mm T-1 3/4), radial package configuration, and through-hole mounting. However, the significant reduction in millicandela rating (2000mcd to 25mcd) and change from clear to diffused lens transparency require functional validation that the application tolerates these brightness characteristics.

Q: What are the key differences between these parts?

A: The primary differences are lens transparency (clear vs. diffused), brightness output (2000mcd vs. 25mcd), and viewing angle (30° vs. 45°). Forward voltage differs by 0.1V (1.9V to 2V), and test current differs by 10mA (30mA to 20mA). The 5YD is active, whereas the 5UYC-2K is obsolete.

Q: Are there packaging considerations for substitution?

A: Both parts use radial package configuration with T-1 3/4 lens size and compatible height specifications (8.80mm vs. 8.50mm maximum). Packaging is identical from a through-hole mounting perspective.

Q: What compliance certifications apply to both parts?

A: Both the 5UYC-2K and 5YD carry identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications. Moisture sensitivity level (MSL 1 - Unlimited) is identical. The 5YD carries RoHS3 compliance status.
