FN15792_RONDA-REC-90-B Equivalent & Substitute Parts

Part Overview

The FN15792_RONDA-REC-90-B is a lens with integrated mount manufactured by Ledil, part of the Rhonda series. This component features a clear acrylic construction with a 90° elliptical/oval optical pattern and twist lock mounting mechanism, designed for single LED applications with a 69.9mm diameter round flat-top lens profile. The product is currently obsolete, necessitating identification of functionally equivalent alternatives for ongoing applications and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FN15792_RONDA-REC-90-B is determined by the following critical parameters:

Primary Compatibility Criteria:

• Manufacturer: Ledil (same manufacturer ensures design compatibility within Rhonda series)
• Lens Size: 69.9mm Dia (physical form factor requirement)
• Lens Style: Round with Flat Top (optical geometry)
• Material: Acrylic (optical and thermal properties)
• Color: Clear (light transmission characteristics)
• Number of LEDs: 1 (single LED application)
• RoHS Status: ROHS3 Compliant (regulatory requirement)
• REACH Status: REACH Unaffected (regulatory requirement)

Secondary Variation Parameters:

• Viewing Angle: 90° (primary specification; substitutes may vary within optical performance envelope)
• Optical Pattern: Elliptical/Oval (primary specification; substitutes may vary)
• Mounting Type: Twist Lock (primary specification; substitutes may use alternative mounting)

The substitute part F15788_RONDA-REC-90 shares the core physical and material specifications but differs in viewing angle (80° vs. 90°), optical pattern (Wide vs. Elliptical/Oval), and mounting type (Socket vs. Twist Lock). These differences represent functional variations within the Rhonda lens family rather than direct equivalents.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Obsolete Part Mitigation):

The FN15792_RONDA-REC-90-B is obsolete. The F15788_RONDA-REC-90 is the active equivalent within the Ledil Rhonda/Ronda lens family. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for new designs and production continuity.

Functional Differences Requiring Design Consideration:

The substitute part F15788_RONDA-REC-90 introduces three functional variations:

• Viewing angle reduced from 90° to 80°
• Optical pattern changed from elliptical/oval to wide distribution
• Mounting mechanism changed from twist lock to socket interface

These variations necessitate mechanical redesign of the mounting interface and optical performance re-evaluation in the target application. The substitute is suitable only where the 80° viewing angle and wide optical pattern are compatible with system requirements.

Compliance Status:

Both parts satisfy ROHS3 and REACH regulatory frameworks, enabling use in regulated markets without additional compliance documentation.

Frequently Asked Questions (FAQ)

Q: Can F15788_RONDA-REC-90 be used as a direct drop-in replacement for FN15792_RONDA-REC-90-B?

A: No. While both parts share identical lens size (69.9mm Dia), material (acrylic), and color (clear), the mounting type differs (socket vs. twist lock). Mechanical redesign of the mounting interface is required. Additionally, the viewing angle (80° vs. 90°) and optical pattern (wide vs. elliptical/oval) differ, requiring optical performance re-evaluation.

Q: Why is the main part FN15792_RONDA-REC-90-B marked as obsolete?

A: Product obsolescence is determined by the manufacturer. The active substitute F15788_RONDA-REC-90 represents the current production equivalent within the Ledil Rhonda lens family.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both FN15792_RONDA-REC-90-B and F15788_RONDA-REC-90 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component use.

Q: What is the primary difference in optical performance between these parts?

A: The main part provides a 90° elliptical/oval optical pattern, while the substitute provides an 80° wide optical pattern. These represent different light distribution characteristics and are not optically equivalent.

Q: Does the packaging differ between these parts?

A: Yes. FN15792_RONDA-REC-90-B packaging is listed as "-" (unspecified), while F15788_RONDA-REC-90 is packaged in trays. Confirm packaging requirements for your supply chain and assembly process.

Q: Can I use the substitute part in a new design?

A: Yes, provided your application requirements are compatible with the 80° viewing angle, wide optical pattern, and socket mounting type. The part is active and available from Ledil.
