OPTX1016S Equivalent & Substitute Parts

Part Overview

The OPTX1016S is a clear lens sub-assembly manufactured by Dialight, designed for single LED applications with a 32° wide viewing angle and 26mm diameter round form factor with flat top profile. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

The OPAA1WSL qualifies as a functional substitute based on the following alignment of critical parameters:

• Identical manufacturer (Dialight)
• Matching lens size (26mm diameter)
• Identical lens style (round with flat top)
• Matching color specification (clear)
• Identical single LED configuration
• Equivalent wide optical pattern classification
• Viewing angle within acceptable tolerance (30° versus 32°)
• Identical moisture sensitivity level (MSL 1)
• Matching regulatory compliance (REACH Unaffected, EAR99)

The primary distinction is the mounting type: OPAA1WSL features snap-in mounting versus the standard mounting of OPTX1016S, and includes diffused lens transparency specification.

Parameter Comparison

Engineering Selection Recommendations

OPAA1WSL is the active production equivalent for OPTX1016S. The substitute maintains critical optical and mechanical specifications while offering the advantage of active product status and current manufacturing availability. The 2° reduction in viewing angle (30° versus 32°) represents a minor optical characteristic variance within typical lens design tolerances for wide-angle applications.

Substitution is appropriate for applications where snap-in mounting compatibility exists in the host assembly. The diffused transparency specification of OPAA1WSL may affect light transmission characteristics compared to the unspecified transparency of the original part; this distinction should be evaluated against specific application requirements.

Frequently Asked Questions (FAQ)

Q: Can OPAA1WSL directly replace OPTX1016S in existing assemblies?

A: Mechanical and optical compatibility is established through matching lens diameter, style, and wide-angle optical pattern. Mounting type compatibility must be verified; OPAA1WSL uses snap-in mounting while OPTX1016S uses standard mounting. Confirm the host assembly accommodates snap-in installation before substitution.

Q: What is the significance of the 2° viewing angle difference?

A: Both parts are classified as wide optical pattern lenses. The 2° variance (32° to 30°) falls within normal design tolerances for this lens category and does not alter the functional classification or primary optical behavior.

Q: Does the diffused transparency of OPAA1WSL affect performance?

A: Lens transparency directly influences light transmission and beam characteristics. The diffused specification of OPAA1WSL may produce different light distribution compared to the unspecified transparency of OPTX1016S. Application-specific light output requirements should be evaluated.

Q: Are both parts compliant with current regulations?

A: Both OPTX1016S and OPAA1WSL carry REACH Unaffected status and EAR99 classification, confirming equivalent regulatory compliance for export and environmental standards.

Q: What is the inventory status for each part?

A: OPTX1016S is obsolete with 803 units in stock. OPAA1WSL is active production status with 5467 units available, providing superior long-term procurement reliability.
