Key Parameters

Substitute Part Grouping Explanation

Substitution of the FN15971_RONDA-WAS-C is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Manufacturer: Ledil (same manufacturer ensures design compatibility within Ronda series)
• Series: Ronda (maintains mechanical and optical interface standards)
• Mounting Type: Socket (ensures physical installation compatibility)
• Material: Acrylic (maintains optical and thermal properties)
• Number of LEDs: 1 (single LED application requirement)
• Color: Clear (optical transmission requirement)

Allowable Variation Parameters:

• Lens Style: May differ (Round with Flat Top vs. Round Irregular Top)
• Lens Size: May differ (53.9mm Dia vs. 69.9mm Dia)
• Lens Transparency: May differ (Diffused vs. unspecified)
• Optical Pattern: May differ (Asymmetrical vs. Wide)

The substitute part F15156_RONDA-WAS qualifies as an equivalent alternative based on shared mandatory parameters while accommodating optical pattern and lens geometry variations appropriate for different application requirements.

Engineering Selection Recommendations

Primary Substitute: F15156_RONDA-WAS

The F15156_RONDA-WAS is the manufacturer-recommended substitute for the obsolete FN15971_RONDA-WAS-C. Selection of this alternative is supported by the following engineering criteria:

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity in applications subject to environmental directives.

Product Status: The substitute part maintains active production status with confirmed inventory availability (1030 Pcs), providing supply chain reliability for ongoing procurement requirements.

Series Compatibility: Both components belong to the Ledil Ronda series, ensuring mechanical interface compatibility with existing socket-based mounting infrastructure.

Material and Mounting Consistency: Acrylic material composition and socket mounting type are preserved, maintaining thermal and mechanical performance characteristics.

Optical Pattern Differentiation: The F15156_RONDA-WAS features a wide optical pattern compared to the asymmetrical pattern of the main part. This difference reflects distinct light distribution characteristics suitable for applications requiring broader viewing angles or different beam geometry.

Dimensional Variation: The substitute part features a larger lens diameter (69.9mm vs. 53.9mm). This dimensional change must be evaluated against specific application space constraints and optical performance requirements.

Frequently Asked Questions (FAQ)

Q: Can F15156_RONDA-WAS be used as a direct replacement for FN15971_RONDA-WAS-C?

A: F15156_RONDA-WAS is the manufacturer-recommended substitute. Both parts share the same manufacturer, series, material, and mounting type. However, the substitute features different lens geometry (Round Irregular Top vs. Round with Flat Top), larger diameter (69.9mm vs. 53.9mm), and different optical pattern (Wide vs. Asymmetrical). Compatibility depends on whether the application can accommodate these dimensional and optical differences.

Q: What is the primary difference between the optical patterns?

A: The FN15971_RONDA-WAS-C features an asymmetrical optical pattern, while the F15156_RONDA-WAS features a wide optical pattern. These differences affect light distribution characteristics and viewing angle performance. Selection between these patterns depends on specific application requirements for beam geometry and light distribution.

Q: Are there packaging differences between these parts?

A: The main part (FN15971_RONDA-WAS-C) is packaged in unspecified format with 825 Pcs available. The substitute part (F15156_RONDA-WAS) is packaged in Tray format with 1030 Pcs available. Packaging format may affect handling, storage, and integration into assembly processes.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both FN15971_RONDA-WAS-C and F15156_RONDA-WAS are ROHS3 compliant and REACH unaffected. Both carry EAR99 ECCN classification. Regulatory compliance is maintained across the substitution.

Q: What is the significance of the lens size difference?

A: The substitute part features a 69.9mm diameter lens compared to the 53.9mm diameter of the main part. This 16mm increase in diameter represents a significant dimensional change that may affect mechanical fit within existing optical assemblies, heat dissipation characteristics, and overall system geometry. Application-specific mechanical design review is necessary.

Q: Why is the main part classified as obsolete?

A: The FN15971_RONDA-WAS-C is classified as obsolete, indicating discontinued production by the manufacturer. The F15156_RONDA-WAS maintains active production status, ensuring long-term supply availability and continued manufacturer support for new designs and ongoing applications.
