Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FCN10783_LE1-M is determined by the following critical parameters:

Primary Compatibility Criteria:

• Lens size: 21.6mm diameter
• Lens style: Round with flat top
• Material: Acrylic
• Mounting type: Adhesive
• Number of LEDs: Single LED application
• Color: Clear
• Optical pattern: Medium

Secondary Compatibility Criteria:

• Viewing angle tolerance
• Product status and availability
• Regulatory compliance (RoHS3, REACH)

The substitute part F10434_LE1-M meets the primary compatibility criteria with a minor deviation in viewing angle specification (25° versus 24°), representing a 1° difference within typical optical design tolerances for this component category.

Parameter Comparison

Engineering Selection Recommendations

The F10434_LE1-M serves as the active substitute for the obsolete FCN10783_LE1-M. Selection of this substitute is based on the following engineering factors:

Product Status: The FCN10783_LE1-M is classified as obsolete, while F10434_LE1-M maintains active product status with confirmed inventory availability (863 pieces in stock).

Regulatory Compliance: Both components maintain ROHS3 compliance and REACH unaffected status, ensuring compatibility with current environmental and safety standards.

Physical and Optical Compatibility: Identical lens diameter (21.6mm), lens style (round with flat top), material composition (acrylic), and mounting methodology (adhesive) ensure mechanical interchangeability in existing designs.

Optical Specification Variance: The 1° viewing angle difference (24° to 25°) represents a minor optical characteristic variation within acceptable tolerances for medium optical pattern applications.

Packaging Consideration: F10434_LE1-M is supplied in tray packaging, differing from the original specification notation.

Frequently Asked Questions (FAQ)

Q: Can F10434_LE1-M directly replace FCN10783_LE1-M in existing assemblies?

A: Yes. Both components share identical mechanical dimensions (21.6mm diameter), lens style (round with flat top), material (acrylic), and adhesive mounting type. The 1° viewing angle difference (24° to 25°) does not prevent mechanical or functional substitution in single LED applications with medium optical patterns.

Q: What is the significance of the viewing angle difference between 24° and 25°?

A: The 1° difference represents a minor variation in light distribution characteristics. Both components are specified for medium optical patterns and maintain the same lens diameter and style, making this variance acceptable for equivalent optical performance in most applications.

Q: Why is FCN10783_LE1-M classified as obsolete?

A: Product obsolescence indicates that the component is no longer in active production. F10434_LE1-M is the active equivalent available for new designs and ongoing procurement.

Q: Are there packaging differences between these parts?

A: FCN10783_LE1-M packaging is not specified in available documentation. F10434_LE1-M is supplied in tray packaging. Confirm packaging requirements with procurement specifications.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both FCN10783_LE1-M and F10434_LE1-M are ROHS3 compliant and REACH unaffected, meeting current environmental and safety standards.

Q: What is the inventory status for substitution?

A: F10434_LE1-M has 863 pieces available in stock as new original inventory, ensuring supply availability for design transitions and production requirements.
