Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CP12820_EVA-W are identified based on strict alignment of the following critical parameters:

Mechanical Compatibility:

• Identical lens diameter (37.7mm)
• Identical lens style (Round with Flat Top)
• Compatible mounting methods (Adhesive and/or Screw)

Optical Compatibility:

• Matching lens transparency (Diffused)
• Matching optical pattern (Wide)
• Viewing angle within the specified range (45° or compatible angles)

Material & Environmental Compliance:

• Identical material composition (Acrylic)
• Matching RoHS compliance status (ROHS3 Compliant)
• Equivalent MSL rating (1 - Unlimited)

Functional Specifications:

• Single LED application (1 LED)
• Clear color specification
• Ledil manufacturer origin

The CA12804_EVA-W qualifies as a substitute based on full alignment across all mechanical, optical, and compliance parameters, with the addition of extended viewing angle options (45°, 48°).

Mechanical & Optical Equivalence:

• Identical lens geometry, size, and optical characteristics
• Full compatibility with existing mechanical interfaces
• Mounting method compatibility with screw attachment; adhesive mounting transitions from standard adhesive to adhesive tape format

Inventory Availability:

• CA12804_EVA-W: 879 Pcs in stock (Active status)
• CP12820_EVA-W: 727 Pcs in stock (Obsolete status)

For new designs or production continuity, CA12804_EVA-W is the appropriate selection. For existing systems currently using CP12820_EVA-W, CA12804_EVA-W provides direct functional replacement with enhanced supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can CA12804_EVA-W directly replace CP12820_EVA-W in existing assemblies?

A: Yes. Both components share identical lens diameter (37.7mm), lens style (Round with Flat Top), optical pattern (Wide), transparency (Diffused), and material composition (Acrylic). The primary difference is the mounting adhesive format: CP12820_EVA-W uses standard adhesive, while CA12804_EVA-W uses adhesive tape. Both support screw mounting. Mechanical fit and optical performance are equivalent.

Q: What is the difference in viewing angle between these parts?

A: CP12820_EVA-W specifies a 45° viewing angle. CA12804_EVA-W offers dual viewing angle options: 45° and 48°. For applications requiring exactly 45°, CA12804_EVA-W with 45° specification is the appropriate selection. The 48° option provides extended angular coverage for applications requiring broader light distribution.

Q: Why is CP12820_EVA-W classified as obsolete?

A: CP12820_EVA-W is marked as Obsolete, indicating it is no longer in active production. CA12804_EVA-W maintains Active status, ensuring ongoing manufacturing support, supply availability, and compliance updates. For production continuity, CA12804_EVA-W is the recommended selection.

Q: Are there compliance differences between these parts?

A: No. Both CP12820_EVA-W and CA12804_EVA-W are ROHS3 Compliant, REACH Unaffected, and carry identical MSL ratings (1 - Unlimited). Compliance certifications are equivalent.

Q: What is the packaging difference?

A: CP12820_EVA-W packaging is listed as "-" (unspecified). CA12804_EVA-W is packaged in Trays. For procurement and handling, verify tray packaging specifications with your supplier.

Q: Can I use CA12804_EVA-W in applications originally designed for CP12820_EVA-W?

A: Yes, provided the mounting method transition from standard adhesive to adhesive tape is compatible with your assembly process. Optical and mechanical specifications are fully equivalent. Screw mounting remains unchanged.
