OPK21DIF6 Equivalent & Substitute Parts

Part Overview

The OPK21DIF6 is a clear lens sub-assembly manufactured by Dialight, designed for use with Lumileds LED components. This lens features a 12° spot optical pattern and is classified as an obsolete product. Due to its discontinued status, identifying functionally equivalent substitute parts is essential for system redesign, maintenance, and component sourcing in applications requiring compatible optical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitute part identification for the OPK21DIF6 is based on the following critical parameters:

• Lens Type & Function: Single LED sub-lens assembly
• Color: Clear optical material
• Optical Characteristics: Viewing angle and light distribution pattern
• Compatibility: Related manufacturer and mounting interface
• Regulatory Compliance: REACH and export classification alignment

The identified substitute OPAA1DF shares the core lens sub-assembly function and clear color specification. However, substitution requires evaluation of differences in optical pattern (diffuser vs. spot), viewing angle (10° vs. 12°), and mounting methodology (snap-in vs. standard mounting).

Parameter Comparison

Engineering Selection Recommendations

The OPAA1DF is an active product from Dialight with current inventory availability (1882 pcs), providing supply continuity for the obsolete OPK21DIF6. Both parts maintain identical MSL ratings and regulatory compliance status (REACH Unaffected, ECCN EAR99).

Substitution feasibility depends on application-specific optical requirements. The OPK21DIF6 delivers a 12° spot pattern, while OPAA1DF provides a 10° diffuser pattern. These differences in viewing angle and light distribution characteristics must be evaluated against system performance specifications. The OPAA1DF employs snap-in mounting, which may require mechanical interface verification against the original OPK21DIF6 mounting configuration.

Frequently Asked Questions (FAQ)

Q: Can OPAA1DF directly replace OPK21DIF6 in existing assemblies?

A: Direct mechanical and optical compatibility must be confirmed. While both are single-LED clear lenses from Dialight with matching MSL and regulatory status, the OPAA1DF features a different optical pattern (diffuser vs. spot), viewing angle (10° vs. 12°), and mounting type (snap-in). Physical fit and optical performance must be validated for your specific application.

Q: What are the key differences between these substitute parts?

A: The primary differences are optical pattern (spot vs. diffuser), viewing angle (12° vs. 10°), lens style (unspecified vs. round with flat top), and mounting methodology (unspecified vs. snap-in). Material composition differs (unspecified vs. acrylic). These parameters directly affect light distribution and mechanical integration.

Q: Are both parts compliant with current regulations?

A: Yes. Both OPK21DIF6 and OPAA1DF maintain REACH Unaffected status and EAR99 export classification. Both carry MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling.

Q: What is the availability status of these parts?

A: OPK21DIF6 is obsolete with 1088 pcs in stock. OPAA1DF is an active product with 1882 pcs currently available, providing reliable supply for new designs and replacements.

Q: How should mounting compatibility be verified?

A: The OPAA1DF uses snap-in mounting, while OPK21DIF6 mounting type is not specified in available documentation. Physical interface verification with your PCB or housing assembly is required before implementation.
