Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FN15381_RONDA-WWW is determined by the following critical parameters:

Primary Compatibility Criteria:

• Manufacturer: Ledil (same manufacturer ensures design compatibility within Ronda series)
• Series: Ronda (maintains mechanical and optical design consistency)
• Type: Lens (functional category match)
• Color: Clear (optical transmission requirement)
• Number of LEDs: 1 (single LED application)
• Material: Acrylic (material specification)
• Optical Pattern: Wide (beam distribution characteristic)
• RoHS Status: ROHS3 Compliant (regulatory requirement)

Secondary Compatibility Parameters:

• Lens Size: Physical diameter accommodation in housing
• Lens Style: Mechanical form factor (domed vs. flat top)
• Mounting Type: Mechanical attachment method (twist lock vs. socket)
• Viewing Angle: Optical performance range

The substitute part F15157_RONDA-WWW shares the same manufacturer, series, type, color, LED count, material, optical pattern, and RoHS compliance status. Differences exist in lens style, lens size, mounting type, and viewing angle, which represent design trade-offs for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The FN15381_RONDA-WWW is classified as obsolete. The F15157_RONDA-WWW is classified as active product status, indicating ongoing manufacturer support, availability, and compliance maintenance.

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying current environmental and hazardous substance regulations applicable to electronic component procurement.

Design Integration: Selection between these parts depends on mechanical housing design and optical performance requirements. The main part features a twist lock mounting mechanism with a 49.9mm diameter domed lens and 72° to 85° viewing angle. The substitute part features socket mounting with a 69.9mm diameter flat-top lens and 90° viewing angle. Housing modifications may be required to accommodate the larger diameter and different mounting interface of the substitute part.

Availability: Current inventory indicates 690 pieces of the substitute part F15157_RONDA-WWW available in active status, compared to 947 pieces of the obsolete main part. For new designs or long-term production planning, the active substitute part provides supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can F15157_RONDA-WWW directly replace FN15381_RONDA-WWW in existing assemblies?

A: Direct mechanical replacement is not possible without housing modification. The substitute part has a larger diameter (69.9mm vs. 49.9mm), different mounting type (socket vs. twist lock), and different lens style (flat top vs. domed top). Housing redesign is required for integration.

Q: What are the optical differences between these two lenses?

A: The main part provides a 72° to 85° viewing angle with diffused transparency and domed top geometry. The substitute part provides a 90° viewing angle with flat top geometry. The wider 90° angle of the substitute part results in broader light distribution.

Q: Are both parts suitable for the same LED manufacturers?

A: The main part is specified for use with Bridgelux, Cree, Lumileds, Nichia, Philips, Samsung, Seoul, and Tridonic LEDs. The substitute part does not specify related manufacturers in the provided data. LED compatibility should be evaluated based on optical and mechanical requirements of the specific application.

Q: What is the packaging difference?

A: The main part packaging is listed as dash (standard). The substitute part is packaged in trays, which may affect handling, storage, and assembly line integration procedures.

Q: Why is the main part obsolete?

A: Product obsolescence is determined by the manufacturer. The active status of the substitute part within the same Ronda series indicates that Ledil has transitioned product lines. For new designs, the active substitute part should be considered for supply chain reliability.

Q: Are there compliance differences between the two parts?

A: Both parts maintain identical RoHS3 compliance and REACH unaffected status. No compliance differentiation exists between the two parts.
