Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FN15552_RONDA-W is determined by the following critical parameters:

Mechanical Compatibility:

• Lens size (69.9mm diameter)
• Lens style (round with flat top)
• Mounting interface (screw or twist lock)
• Material composition (acrylic)

Optical Characteristics:

• Single LED application
• Clear color specification
• Viewing angle range and optical pattern

Regulatory & Environmental:

• ROHS3 compliance
• REACH unaffected status
• MSL rating compatibility

The identified substitute part F15443_RONDA-W shares the same manufacturer (Ledil), series (Ronda), lens size (69.9mm), lens style (round with flat top), material (acrylic), and regulatory compliance profile. However, this substitute exhibits a narrower viewing angle (45° versus 54°/57°) and medium optical pattern (versus wide), with socket mounting rather than screw/twist lock configuration.

Parameter Comparison

Engineering Selection Recommendations

Primary Consideration: Product Status

The FN15552_RONDA-W is classified as obsolete. The F15443_RONDA-W is an active product from the same manufacturer and series, ensuring continued availability and supply chain stability.

Mechanical Interface Compatibility

The substitute part utilizes socket mounting rather than screw/twist lock mounting. Design integration requires mechanical interface modification or adapter solutions to accommodate this change.

Optical Performance Variance

The substitute part provides a 45° viewing angle with medium optical pattern characteristics, compared to the main part's 54°/57° wide viewing angle. Applications requiring the specific wide-angle optical distribution of the original part will experience altered light distribution with this substitute.

Regulatory Compliance

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent component substitution.

Inventory & Availability

The F15443_RONDA-W maintains active inventory status (923 pcs in stock) with tray packaging, supporting production and procurement continuity.

Frequently Asked Questions (FAQ)

Q: Can F15443_RONDA-W directly replace FN15552_RONDA-W without design modification?

A: No. The substitute part differs in mounting type (socket versus screw/twist lock) and optical characteristics (45° medium versus 54°/57° wide). Mechanical interface redesign is required.

Q: What is the primary reason for seeking a substitute for FN15552_RONDA-W?

A: The FN15552_RONDA-W is classified as obsolete. The F15443_RONDA-W is an active product from Ledil's Ronda series, ensuring long-term availability and supply chain support.

Q: Are both parts compatible with the same LED manufacturers?

A: Both parts are designed for single LED applications. The main part specifies compatibility with Bridgelux, Cree, Lumileds, Nichia, Philips, and Tridonic. The substitute part does not specify related manufacturers in the provided data.

Q: What is the impact of the viewing angle difference between these parts?

A: The main part provides 54°/57° wide viewing angle distribution. The substitute provides 45° viewing angle with medium optical pattern. Applications requiring wide-angle light distribution will experience narrower beam characteristics with the substitute.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, meeting equivalent regulatory requirements for component substitution.

Q: What packaging differences exist between these parts?

A: The main part packaging is specified as dash (-). The substitute part is supplied in tray packaging, which may affect procurement, handling, and assembly processes.

Q: Is the acrylic material composition identical between both parts?

A: Yes. Both parts utilize acrylic as the lens material, maintaining equivalent optical and environmental properties.
