FCX10853_RES-SS Equivalent & Substitute Parts

Part Overview

The FCX10853_RES-SS is a lens with holder assembly manufactured by Ledil, designed for single LED applications. This component features a clear polycarbonate construction with a square flat-top lens geometry and adhesive tape mounting. The part operates with a 13°, 14° spot optical pattern and is classified as obsolete product status.

Due to obsolete product status, sourcing equivalent or substitute components is necessary for ongoing production, maintenance, and new design implementations. Substitute parts must maintain compatibility across optical performance, mechanical dimensions, material composition, and mounting methodology.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FCX10853_RES-SS is determined by the following critical parameters:

Mechanical Compatibility:

• Lens size: 21.6mm x 21.6mm (fixed requirement)
• Lens style: Square with flat top (fixed requirement)
• Mounting type: Adhesive tape (fixed requirement)

Optical Compatibility:

• Optical pattern: Spot (fixed requirement)
• Material: Polycarbonate (fixed requirement)
• Color: Clear (fixed requirement)
• Number of LEDs: 1 (fixed requirement)

Regulatory & Environmental:

• RoHS3 compliance (required)
• REACH unaffected status (required)
• MSL rating: 1 or equivalent (required)

Allowable Variation:

• Viewing angle: Substitutes may vary within the spot optical pattern category, provided the angle specification remains within acceptable application parameters

The substitute part F10332_ROSE-B-B-SS meets all mechanical, optical, and regulatory requirements while maintaining the same lens geometry, material, and mounting methodology. The viewing angle differs at 15° compared to the original 13°, 14° specification, representing a minor optical variation within the Rose series spot lens family.

Parameter Comparison

Engineering Selection Recommendations

The F10332_ROSE-B-B-SS is classified as an active product with current manufacturing status, providing supply chain continuity for applications previously utilizing the obsolete FCX10853_RES-SS. Both components maintain identical mechanical dimensions, material composition, and mounting methodology.

Selection of the substitute part is supported by:

• Active product status ensuring ongoing availability and supply reliability
• ROHS3 compliance and REACH unaffected status matching regulatory requirements of the original part
• Identical lens geometry and polycarbonate material specification
• Consistent adhesive tape mounting interface
• Rose series optical design family continuity

The 15° viewing angle of the substitute represents a 1° to 2° increase relative to the original 13°, 14° specification. This optical variation remains within the spot pattern category and reflects standard design progression within the Rose series lens family.

Frequently Asked Questions (FAQ)

Q: Can F10332_ROSE-B-B-SS be used as a direct replacement for FCX10853_RES-SS?

A: F10332_ROSE-B-B-SS maintains mechanical and material compatibility with identical lens size (21.6mm x 21.6mm), square flat-top geometry, polycarbonate material, and adhesive tape mounting. The viewing angle differs at 15° versus 13°, 14°. Compatibility depends on application-specific optical requirements.

Q: What is the difference between "Lens With Holder" and "Lens" type designations?

A: FCX10853_RES-SS is classified as "Lens With Holder," indicating an integrated assembly. F10332_ROSE-B-B-SS is classified as "Lens," indicating the optical element. Both components function within the same mechanical envelope and mounting interface.

Q: Are there regulatory compliance differences between the parts?

A: Both components maintain ROHS3 compliance and REACH unaffected status. No regulatory compliance differences exist between the original and substitute part.

Q: What does the packaging difference (Adhesive Tape vs. Tray) indicate?

A: Packaging format reflects current manufacturing and distribution methodology. The adhesive tape mounting type remains consistent between both parts. Tray packaging for F10332_ROSE-B-B-SS represents standard active product distribution.

Q: How does the 15° viewing angle of the substitute affect optical performance?

A: The 15° viewing angle represents a 1° to 2° increase in beam divergence compared to the original 13°, 14° specification. This variation remains within the spot optical pattern classification and reflects standard design parameters within the Rose series lens family.

Q: Is the substitute part suitable for new design implementations?

A: F10332_ROSE-B-B-SS is classified as active product status, making it suitable for new design implementations. The mechanical and optical specifications align with Rose series design standards.
