Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FN15978_RONDA-WAS2-B is determined by the following critical parameters:

Primary Compatibility Criteria:

• Manufacturer: Ledil (same manufacturer ensures design compatibility within the Ronda series)
• Series: Ronda (maintains mechanical and optical interface standards)
• Mounting Type: Socket (ensures physical installation compatibility)
• Material: Acrylic (maintains optical and thermal properties)
• Color: Clear (preserves light transmission characteristics)
• Number of LEDs: 1 (single LED application requirement)
• Lens Style: Round with Flat Top (maintains form factor and mounting interface)

Secondary Consideration:

• Product Status: Active status required for ongoing availability and supply chain reliability

The substitute part F15862_RONDA-WAS2 shares the core compatibility parameters with the main part, with the exception of lens size (53.9mm versus 69.9mm) and optical pattern (wide versus asymmetrical). These differences represent design trade-offs in optical distribution characteristics and physical envelope.

Parameter Comparison

Engineering Selection Recommendations

Compliance and Regulatory Status: Both the main part FN15978_RONDA-WAS2-B and substitute F15862_RONDA-WAS2 maintain ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory requirements for electronic component applications.

Supply Chain Considerations: The main part FN15978_RONDA-WAS2-B is classified as obsolete with 733 pieces in current inventory. The substitute part F15862_RONDA-WAS2 maintains active product status with 1148 pieces available, providing superior long-term supply chain reliability and availability for ongoing production requirements.

Design Integration: Both components are manufactured by Ledil within the Ronda series and utilize identical mounting type (socket) and material composition (acrylic). The primary design differences are lens diameter (69.9mm versus 53.9mm) and optical distribution pattern (asymmetrical versus wide). Component selection must account for these optical and mechanical envelope differences in the target application.

Frequently Asked Questions (FAQ)

Q: Can F15862_RONDA-WAS2 be used as a direct replacement for FN15978_RONDA-WAS2-B?

A: Both components share core compatibility parameters including manufacturer (Ledil), series (Ronda), mounting type (socket), material (acrylic), and single LED configuration. However, the substitute part differs in lens diameter (53.9mm versus 69.9mm) and optical pattern (wide versus asymmetrical). Direct substitution is possible only if the application tolerates these dimensional and optical distribution changes.

Q: What are the key differences between these two lens assemblies?

A: The primary differences are: (1) Lens size—FN15978_RONDA-WAS2-B features a 69.9mm diameter lens while F15862_RONDA-WAS2 is 53.9mm diameter; (2) Optical pattern—the main part provides asymmetrical light distribution while the substitute provides wide distribution; (3) Product status—the main part is obsolete while the substitute is active; (4) Type classification—the main part is listed as lens with holder while the substitute is listed as lens only.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both FN15978_RONDA-WAS2-B and F15862_RONDA-WAS2 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic component applications.

Q: What packaging is available for the substitute part?

A: The substitute part F15862_RONDA-WAS2 is supplied in tray packaging. Packaging information for the main part is not specified in the available documentation.

Q: Why is the main part classified as obsolete?

A: FN15978_RONDA-WAS2-B is designated as obsolete by the manufacturer. The active substitute F15862_RONDA-WAS2 is recommended for new designs and ongoing production to ensure supply chain continuity and manufacturer support.
