Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CP12819_EVA-M are identified based on strict equivalence of the following critical parameters:

• Lens diameter: 37.7mm
• Lens geometry: Round with flat top
• Viewing angle: 26°
• Optical pattern: Medium
• Lens transparency: Diffused
• Material composition: Acrylic
• LED count: Single LED (1)
• Color: Clear
• Manufacturer: Ledil
• Series: EVA
• RoHS compliance: ROHS3 Compliant
• MSL rating: 1 (Unlimited)

The CA12803_EVA-M qualifies as a substitute part because it maintains equivalence across all critical optical, mechanical, and material parameters. The primary distinction between the main part and substitute relates to mounting method configuration and product status.

Parameter Comparison

Engineering Selection Recommendations

The CA12803_EVA-M serves as the active equivalent for the obsolete CP12819_EVA-M. Both components maintain identical optical specifications, mechanical dimensions, and material properties. The substitution is valid from an optical and mechanical compatibility standpoint.

The primary difference between these parts is the mounting adhesive method: CP12819_EVA-M uses standard adhesive, while CA12803_EVA-M uses adhesive tape. This distinction affects assembly procedures but does not alter optical performance or mechanical fit.

The CA12803_EVA-M carries active product status and maintains full ROHS3 compliance and MSL 1 rating, ensuring continued availability and regulatory compliance for new designs and production continuity.

Frequently Asked Questions (FAQ)

Q: Can CA12803_EVA-M directly replace CP12819_EVA-M in existing assemblies?

A: The CA12803_EVA-M is optically and mechanically equivalent to CP12819_EVA-M. The primary consideration is the mounting method difference: adhesive versus adhesive tape. Assembly procedures must account for this distinction.

Q: What is the significance of the mounting type difference?

A: CP12819_EVA-M uses adhesive with screw mounting, while CA12803_EVA-M uses adhesive tape with screw mounting. Both methods provide mechanical retention. The adhesive tape variant may offer different handling characteristics during assembly.

Q: Are the optical characteristics identical between these parts?

A: Yes. Both parts feature 26° viewing angle, medium optical pattern, diffused transparency, and 37.7mm diameter clear acrylic lenses. Optical performance is equivalent.

Q: Why is CP12819_EVA-M listed as obsolete?

A: Product status reflects manufacturer lifecycle decisions. The CA12803_EVA-M remains in active production and provides equivalent functionality.

Q: Do both parts meet the same compliance standards?

A: Yes. Both CP12819_EVA-M and CA12803_EVA-M are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) ratings.

Q: What LED manufacturers are these lenses compatible with?

A: CP12819_EVA-M is specified for Lumileds. CA12803_EVA-M is compatible with both Cree and Lumileds LED sources.
