Substitute Part Grouping Explanation
Substitution of the FN15736_RONDA-WW-B is determined by the following critical parameters:
Optical Compatibility Parameters:
- Lens size: 69.9mm diameter
- Lens style: Round with flat top
- Material: Acrylic
- Color: Clear
- Number of LEDs: Single LED application
Mechanical Compatibility Parameters:
- Mounting interface type
- Physical form factor
Regulatory & Environmental Parameters:
- RoHS3 compliance
- MSL rating of 1 (Unlimited)
- REACH unaffected status
The substitute part F15282_RONDA-WW shares the same lens diameter, material composition, color, and regulatory compliance profile. However, this substitute differs in mounting type (socket versus twist lock) and optical pattern (wide versus asymmetrical). These differences establish distinct application boundaries and require engineering evaluation based on specific installation requirements.

Engineering Selection Recommendations
For Active Production and New Designs:
The F15282_RONDA-WW is the designated manufacturer-recommended substitute and is currently in active product status with 931 units in stock. This part maintains regulatory compliance through ROHS3 certification and REACH unaffected status, matching the environmental requirements of the obsolete FN15736_RONDA-WW-B.
Critical Compatibility Considerations:
The F15282_RONDA-WW employs a socket mounting interface, whereas the FN15736_RONDA-WW-B uses a twist lock mechanism. This mechanical difference requires verification of the host assembly's mounting provisions. The optical pattern differs (wide versus asymmetrical), which affects light distribution characteristics and must be evaluated against application-specific illumination requirements.
Regulatory Compliance:
Both parts maintain equivalent regulatory standing through ROHS3 compliance and REACH unaffected designation, supporting use in regulated applications without additional compliance burden.
Frequently Asked Questions (FAQ)
Q: Can F15282_RONDA-WW directly replace FN15736_RONDA-WW-B in existing assemblies?
A: Physical replacement depends on the host assembly's mounting interface. The FN15736_RONDA-WW-B uses twist lock mounting, while F15282_RONDA-WW uses socket mounting. The mounting provisions must be compatible with the socket interface. Optical performance will differ due to the change from asymmetrical to wide optical pattern.
Q: What is the difference between asymmetrical and wide optical patterns?
A: Asymmetrical optical patterns direct light distribution in a non-uniform manner, while wide patterns distribute light more uniformly across the viewing angle. The FN15736_RONDA-WW-B provides 60° to 67° asymmetrical distribution, whereas F15282_RONDA-WW provides 60° wide distribution. Application requirements determine which pattern is appropriate.
Q: Are both parts environmentally compliant?
A: Yes. Both FN15736_RONDA-WW-B and F15282_RONDA-WW are ROHS3 compliant and REACH unaffected, meeting current environmental regulations for electronic components.
Q: What is the packaging difference?
A: FN15736_RONDA-WW-B packaging is specified as dash (-), while F15282_RONDA-WW is supplied in tray packaging. Tray packaging is standard for active production components and supports automated assembly processes.
Q: Why is FN15736_RONDA-WW-B classified as obsolete?
A: Obsolete status indicates the part is no longer in active production. F15282_RONDA-WW is the active equivalent maintained by Ledil for ongoing supply and new designs.
Q: Are both parts compatible with the same LED sources?
A: FN15736_RONDA-WW-B is specified for use with Bridgelux, Citizen, Cree, Osram, and Sharp LED sources. F15282_RONDA-WW does not specify related manufacturers in the provided data. LED compatibility should be verified based on the specific LED source and mounting interface type.
