Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FN15734_RONDA-S-B is determined by the following critical parameters:

Primary Compatibility Criteria:

• Manufacturer: Ledil (same manufacturer ensures design compatibility within the Rhonda series)
• Lens Size: 69.9mm Dia (mechanical fit requirement)
• Material: Acrylic (optical and thermal properties)
• Color: Clear (optical transmission characteristics)
• Number of LEDs: 1 (single LED application)
• RoHS3 Compliance and REACH Unaffected status (regulatory alignment)

Acceptable Variation Parameters:

• Viewing Angle: 24°, 25°, 27° (within narrow beam spot range)
• Optical Pattern: Spot or Medium (directional light distribution)
• Mounting Type: Twist Lock or Screw (mechanical interface variation)
• Lens Style: Round with Multiple Top or Round with Ripple Top (geometric variation)
• Product Status: Active preferred over Obsolete (supply continuity)

The substitute F15667_RONDA-S meets these criteria with minor optical pattern and mounting type variations.

Parameter Comparison

Engineering Selection Recommendations

Primary Consideration: Product Status

The FN15734_RONDA-S-B is classified as obsolete. The F15667_RONDA-S is an active product from the same manufacturer and series, ensuring continued availability and supply chain stability.

Regulatory Compliance

Both parts maintain ROHS3 compliance and REACH Unaffected status, satisfying current environmental and regulatory requirements for electronic component procurement.

Optical and Mechanical Compatibility

Both parts share identical lens diameter (69.9mm), material composition (acrylic), and color (clear). The viewing angle difference (24°/27° versus 25°) and optical pattern variation (spot versus medium) represent minor optical characteristic differences within the narrow beam category. The mounting type change from twist lock to screw requires mechanical interface evaluation in the target application.

Supply Chain Continuity

F15667_RONDA-S maintains active inventory status (822 Pcs in stock) compared to the obsolete FN15734_RONDA-S-B, supporting long-term procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can F15667_RONDA-S directly replace FN15734_RONDA-S-B in existing assemblies?

A: Direct mechanical replacement requires evaluation of the mounting interface. The main part uses twist lock mounting while the substitute uses screw mounting. The 69.9mm lens diameter and acrylic material are identical. Optical pattern changes from spot to medium and viewing angle adjustment from 24°/27° to 25° must be validated against application requirements.

Q: What are the key differences between these parts?

A: The primary differences are: (1) Product status—FN15734_RONDA-S-B is obsolete while F15667_RONDA-S is active; (2) Mounting mechanism—twist lock versus screw; (3) Optical pattern—spot versus medium; (4) Viewing angle—24°/27° versus 25°; (5) Lens style—round with multiple top versus round with ripple top.

Q: Are both parts compliant with current regulations?

A: Yes. Both FN15734_RONDA-S-B and F15667_RONDA-S are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What is the packaging difference?

A: FN15734_RONDA-S-B packaging is not specified. F15667_RONDA-S is supplied in tray packaging, which may affect handling, storage, and integration procedures.

Q: Why is the viewing angle different between these parts?

A: The main part offers dual viewing angles (24°/27°) while the substitute provides a single 25° angle. This represents a design variation within the narrow beam spot category. Application-specific optical requirements must determine acceptability.

Q: Does the optical pattern change affect performance?

A: The main part features a spot optical pattern while the substitute features a medium optical pattern. Both are directional light distribution types. The specific impact depends on the application's illumination requirements and beam profile specifications.
