Equivalent & Substitute Parts for 3YC5V-S

Part Overview

The 3YC5V-S is a yellow LED indication component manufactured by Bivar Inc., designed for through-hole mounting applications requiring 5V discrete radial configuration. This part operates at 40 millicandela with a clear lens and 30° viewing angle. The product is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design requirements and procurement needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3YC5V-S is determined by the following critical parameters:

Primary Compatibility Criteria:

• Color: Yellow
• Lens Size: 3mm, T-1
• Voltage - Forward (Vf): 5V
• Mounting Type: Through Hole
• Package Configuration: Radial
• Wavelength - Peak: 590nm (±tolerance)

Secondary Compatibility Criteria:

• Millicandela Rating: Functional equivalence within application-dependent brightness requirements
• Current - Test: Operating current within circuit design parameters
• Viewing Angle: Application-specific visibility requirements
• Lens Transparency: Clear or diffused based on optical design intent

The WP710A10YD5V from Kingbright satisfies all primary compatibility criteria and maintains functional equivalence across secondary parameters within acceptable engineering tolerances for yellow LED indication applications.

Engineering Selection Recommendations

The WP710A10YD5V is the designated substitute for the obsolete 3YC5V-S based on the following engineering criteria:

Product Status Alignment: The WP710A10YD5V maintains active product status with Kingbright, ensuring ongoing availability and supply chain continuity for new designs and production requirements.

Compliance and Certifications: Both components share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications. The WP710A10YD5V carries RoHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement.

Functional Equivalence: Core electrical parameters align across forward voltage (5V), wavelength peak (590nm), and through-hole radial mounting configuration. The substitute maintains the same lens size (3mm, T-1) and lens style (round with domed top).

Parameter Variations: The WP710A10YD5V exhibits increased test current (13mA versus 8mA) and reduced millicandela rating (15mcd versus 40mcd). The lens transparency differs (diffused versus clear), and viewing angle is wider (40° versus 30°). These variations require circuit-level evaluation to confirm compatibility with specific application brightness and optical requirements.

Frequently Asked Questions (FAQ)

Q: Can the WP710A10YD5V directly replace the 3YC5V-S without circuit modification?

A: Direct mechanical and electrical substitution is possible due to matching forward voltage (5V), lens size (3mm, T-1), and radial through-hole mounting. However, the increased test current (13mA versus 8mA) and reduced brightness (15mcd versus 40mcd) require verification that the application circuit and optical design accommodate these parameter differences.

Q: What is the significance of the lens transparency difference (clear versus diffused)?

A: The 3YC5V-S features a clear lens, producing a focused light output. The WP710A10YD5V uses a diffused lens, which scatters light over a wider area. This affects perceived brightness and viewing angle characteristics. Application requirements determine which lens type is appropriate.

Q: Are there compliance or supply chain advantages to using the WP710A10YD5V?

A: The WP710A10YD5V carries active product status with 15,982 pieces in stock inventory, compared to the obsolete 3YC5V-S. The substitute meets RoHS3 and REACH compliance standards, supporting modern procurement and regulatory requirements.

Q: How do the viewing angle differences affect application suitability?

A: The 3YC5V-S provides a 30° viewing angle, while the WP710A10YD5V offers 40°. The wider viewing angle of the substitute may be advantageous for applications requiring broader visibility but may not be suitable for applications requiring narrow, focused light output.

Q: What packaging considerations apply to this substitution?

A: Both components use identical T-1 (3mm) through-hole radial packaging. The WP710A10YD5V is supplied in bulk packaging, while the 3YC5V-S was supplied with standard packaging. PCB footprint and mounting procedures remain unchanged.
