Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the 5YC5.523F is determined by alignment across the following critical parameter categories:

Optical Parameters: Color (yellow), lens transparency (clear), and peak wavelength (590nm) must match exactly to ensure proper indication function and visual consistency in circuit applications.

Mechanical Parameters: Lens size (5mm T-1 3/4), mounting type (through hole), and maximum height (8.60mm) must be identical to ensure physical compatibility with existing PCB layouts and mechanical assemblies.

Electrical Parameters: Forward voltage (Vf) and test current must fall within acceptable operating ranges. The 5YC5.523F operates at 2.2V typical with 20mA test current. Substitute components with forward voltage within ±0.2V and identical test current specifications maintain circuit compatibility without requiring design modifications.

Brightness and Viewing Angle: While millicandela rating and viewing angle may vary within functional tolerance, components with comparable or superior brightness ratings and similar viewing angles preserve the intended indication performance.

The substitute part WP7113SYCK/J3 from Kingbright meets all critical substitution criteria across these parameter groups.

Parameter Comparison

Engineering Selection Recommendations

The WP7113SYCK/J3 from Kingbright is a direct functional substitute for the obsolete 5YC5.523F from Bivar Inc. based on the following engineering criteria:

Product Status Alignment: The 5YC5.523F is classified as obsolete, creating supply chain risk. The WP7113SYCK/J3 is active production, ensuring long-term availability and procurement stability.

Compliance and Certifications: The WP7113SYCK/J3 carries ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement. Both components share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications.

Electrical Compatibility: Forward voltage variance of 0.2V (2.2V vs. 2V) falls within standard circuit tolerance for LED indication applications. Test current specification is identical at 20mA, ensuring equivalent power consumption and brightness performance.

Mechanical and Optical Compatibility: All critical mechanical parameters (lens size, mounting type, height) and optical parameters (color, wavelength, lens transparency) are identical. The substitute component integrates directly into existing PCB designs without layout modifications.

Performance Enhancement: The WP7113SYCK/J3 provides 6000mcd brightness compared to 5500mcd in the original component, delivering improved indication visibility while maintaining all other functional specifications.

Frequently Asked Questions (FAQ)

Q: Can the WP7113SYCK/J3 be used as a direct replacement for the 5YC5.523F without circuit modifications?

A: Yes. The WP7113SYCK/J3 is electrically and mechanically compatible with the 5YC5.523F. Forward voltage variance of 0.2V is within standard tolerance for LED indication circuits. No design changes are required for direct substitution in through-hole applications.

Q: What is the significance of the 0.2V forward voltage difference between these components?

A: The 5YC5.523F operates at 2.2V typical while the WP7113SYCK/J3 operates at 2V typical. This 0.2V variance is negligible in standard LED indication circuits and does not require current-limiting resistor recalculation or circuit redesign.

Q: Does the higher millicandela rating of the WP7113SYCK/J3 (6000mcd vs. 5500mcd) affect circuit compatibility?

A: No. Higher brightness is a performance enhancement that does not compromise compatibility. The substitute component will provide improved indication visibility while consuming identical test current (20mA) and maintaining all other electrical specifications.

Q: Are there any compliance or regulatory differences between these components?

A: The WP7113SYCK/J3 carries ROHS3 compliance and REACH unaffected status, meeting current regulatory standards. Both components share identical ECCN and HTSUS classifications. The substitute meets modern procurement compliance requirements.

Q: What is the packaging difference between these components?

A: The 5YC5.523F is supplied in standard packaging, while the WP7113SYCK/J3 is supplied in bulk packaging. Both components use identical radial package configuration and 5mm T-1 3/4 form factor, ensuring mechanical compatibility regardless of packaging format.

Q: Why is the viewing angle slightly different (23° vs. 20°)?

A: The viewing angle variance reflects minor optical design differences between manufacturers while maintaining functional equivalence. Both angles fall within standard ranges for general indication applications. The 20° viewing angle of the substitute is typical for T-1 3/4 LED designs and does not impact circuit performance.
