Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FN15966_RONDA-WWW-C is determined by the following critical parameters:

Primary Compatibility Criteria:

• Manufacturer: Ledil (same manufacturer ensures design consistency)
• Series: Ronda (maintains mechanical and optical compatibility within the product line)
• Mounting Type: Socket (ensures physical compatibility with existing LED sources)
• Material: Acrylic (maintains optical and thermal properties)
• Number of LEDs: 1 (single LED application requirement)
• Lens Style: Round with Flat Top (preserves form factor and integration)
• Color: Clear (maintains optical transparency characteristics)
• Optical Pattern: Wide (ensures similar light distribution profile)

Regulatory Compliance:

• RoHS3 Compliant status required for environmental and regulatory alignment

The substitute part F15157_RONDA-WWW meets these core criteria while offering an active product status, ensuring long-term availability and supply chain stability.

Parameter Comparison

Engineering Selection Recommendations

For Direct Substitution:

The F15157_RONDA-WWW is the manufacturer-recommended substitute for the FN15966_RONDA-WWW-C. Both components share the same manufacturer (Ledil), series designation (Ronda), mounting architecture (socket), and material composition (acrylic). Both maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment.

Key Differences Requiring Evaluation:

The substitute part differs in the following specifications:

1. Lens Size: The substitute features a 69.9mm diameter compared to the original 53.9mm diameter. This larger optical aperture affects the physical envelope and may require mechanical integration review.

2. Viewing Angle: The substitute provides a fixed 90° viewing angle, whereas the original offered selectable angles of 79°, 85°, or 91°. The 90° specification falls within the original range and is suitable for applications requiring wide-angle light distribution.

3. Product Status: The substitute is active, ensuring ongoing availability, technical support, and supply chain continuity compared to the obsolete status of the original part.

4. Type Classification: The substitute is classified as a lens component, while the original is a lens with holder assembly. Integration requirements with existing LED mounting solutions must be assessed.

Compliance Basis:

Both parts maintain equivalent environmental certifications (ROHS3 Compliant, REACH Unaffected) and share the same ECCN classification (EAR99), supporting regulatory and export compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can F15157_RONDA-WWW directly replace FN15966_RONDA-WWW-C in existing assemblies?

A: F15157_RONDA-WWW is the manufacturer-recommended substitute. However, the larger lens diameter (69.9mm vs. 53.9mm) and the absence of a holder assembly in the substitute require mechanical integration assessment. The 90° viewing angle is compatible with the original part's angle range.

Q: What is the significance of the product status change from Obsolete to Active?

A: The substitute's active status ensures long-term component availability, ongoing manufacturing support, and supply chain stability. The original part's obsolete classification indicates it is no longer in production and may face availability constraints.

Q: Are there compliance differences between the two parts?

A: Both parts maintain identical compliance certifications: ROHS3 Compliant, REACH Unaffected, and EAR99 ECCN classification. No regulatory barriers exist for substitution from a compliance perspective.

Q: How does the viewing angle difference affect optical performance?

A: The original part offered 79°, 85°, or 91° viewing angles. The substitute provides a fixed 90° angle, which falls within the original specification range. Applications requiring angles outside this specification would require alternative evaluation.

Q: What packaging considerations apply to the substitute part?

A: The substitute is supplied in tray packaging, whereas the original part packaging is not specified. Procurement and handling procedures should account for the tray format to ensure component protection and inventory management.

Q: Does the lens size increase impact thermal or optical characteristics?

A: The larger 69.9mm diameter provides a larger optical aperture compared to the 53.9mm original. Both components use acrylic material and maintain the same wide optical pattern. Specific thermal or optical performance impacts depend on the LED source specifications and application requirements.
