3YC5V-F

Part Overview

The 3YC5V-F is a yellow LED indication component manufactured by Bivar Inc., configured as a discrete 5V radial through-hole device in T-1 3mm form factor. This part is classified as obsolete, making identification of suitable substitute components essential for ongoing design support and procurement. The component functions as a standard yellow LED indicator for applications requiring 5V operation with 40mcd brightness output.

Key Parameters

Substitute Part Grouping Explanation

Substitute components for the 3YC5V-F are identified based on the following critical parameters that define functional equivalence:

Mechanical Compatibility:

• Lens size: 3mm, T-1 form factor
• Mounting type: Through hole radial configuration
• Package dimensions within acceptable tolerance for PCB layout

Electrical Compatibility:

• Voltage rating: 5V forward voltage operation
• Color: Yellow light emission
• Wavelength: Peak output at 590nm (yellow spectrum)

Performance Parameters:

• Millicandela rating within acceptable range for application requirements
• Test current specifications defining operational parameters
• Viewing angle characteristics for optical performance

The substitute part WP710A10YD5V meets these criteria with compatible electrical specifications and mechanical package designation.

Parameter Comparison

Engineering Selection Recommendations

The WP710A10YD5V (Kingbright) qualifies as a functional substitute for the obsolete 3YC5V-F based on matching electrical specifications (5V forward voltage, yellow color, 590nm peak wavelength) and identical form factor (T-1 3mm through-hole radial package).

Key considerations for substitution:

Brightness Variance: The WP710A10YD5V operates at 15mcd versus the original 40mcd rating. Design integration must account for this reduced brightness output.

Optical Characteristics: The substitute features diffused lens transparency compared to the clear lens of the original part, resulting in broader viewing angle (40° versus 20°). This impacts optical projection characteristics and intensity profile.

Dimensional Tolerance: Maximum height of the substitute is 5.90mm versus 5.30mm for the original, representing a 0.60mm increase requiring verification against PCB layout constraints.

Compliance Status: The WP710A10YD5V carries active product status with ROHS3 compliance and REACH unaffected designation, supporting continued procurement and regulatory compliance for new designs.

Frequently Asked Questions (FAQ)

Q: What makes WP710A10YD5V compatible with 3YC5V-F? A: Both components share identical voltage specifications (5V), color output (yellow), peak wavelength (590nm), and package form factor (T-1 3mm through-hole radial). Electrical and mechanical interfaces are equivalent.

Q: How does the lower millicandela rating affect substitution? A: The WP710A10YD5V operates at 15mcd compared to the original 40mcd. Design validation must confirm that reduced brightness meets application requirements. This is a parametric difference that does not prevent substitution when brightness margins exist in the original design.

Q: Does the diffused lens change optical behavior? A: The WP710A10YD5V uses a diffused lens with 40° viewing angle versus the clear lens and 20° viewing angle of the original. This broadens light distribution, affecting intensity distribution across the viewing cone and spatial illumination characteristics.

Q: Are there dimensional constraints with the substitute? A: The WP710A10YD5V has a maximum height of 5.90mm versus 5.30mm for the 3YC5V-F. PCB layout and mechanical clearance must accommodate this 0.60mm height increase.

Q: What is the significance of the active product status for WP710A10YD5V? A: Active product status indicates ongoing manufacturing and supply availability, supporting long-term procurement and design continuity compared to the obsolete 3YC5V-F.

Q: Are compliance and certifications equivalent between the parts? A: The WP710A10YD5V carries ROHS3 compliance and REACH unaffected designation. Both components share identical ECCN (EAR99) and HTSUS classification (8541.41.0000), supporting regulatory equivalence.
