OPAA1DFL Equivalent & Substitute Parts

Part Overview

The OPAA1DFL is a clear lens sub-assembly from Dialight's OPA series, designed as a 12° spot optical pattern component for single LED applications. This part is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and component procurement.

The OPAA1DFL features a round lens with flat top design and diffused transparency characteristics. Due to its obsolete status, equivalent parts must be evaluated based on shared electrical and mechanical parameters to ensure functional compatibility within the original application context.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the OPAA1DFL are identified based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Manufacturer: Dialight (OPA series continuity)
• Type: Lens, Sub Lens (identical component classification)
• Color: Clear (optical transmission characteristics)
• Number of LEDs: 1 (single LED application)
• Lens Style: Round with Flat Top (mechanical form factor)
• Lens Transparency: Diffused (light diffusion properties)
• Moisture Sensitivity Level: 1 (Unlimited) (environmental tolerance)
• REACH Status: REACH Unaffected (regulatory compliance)

Secondary Consideration:

• Viewing Angle: Variations within the OPA series (10° to 12°) represent acceptable optical pattern differences for diffuser-type lenses within the same product family

The OPAA1DF qualifies as a direct substitute based on alignment with all primary criteria. While the viewing angle differs (10° versus 12°), both parts share identical lens transparency (diffused), optical pattern classification (diffuser), and mechanical mounting characteristics (snap-in design).

Parameter Comparison

Engineering Selection Recommendations

The OPAA1DF is the identified substitute for the obsolete OPAA1DFL based on product family continuity within the Dialight OPA series. Both parts maintain identical regulatory compliance (REACH Unaffected, EAR99 classification) and environmental tolerance ratings (MSL 1).

The OPAA1DF carries active product status with confirmed inventory availability (1882 pcs), providing supply chain continuity for applications requiring OPA series lens sub-assemblies. The part is ROHS3 compliant, meeting current environmental standards.

The 2° viewing angle difference (10° versus 12°) between the substitute and original part represents a minor optical characteristic variation. This difference is inherent to the diffuser-type lens design within the OPA series and does not affect mechanical compatibility or core functional parameters.

Frequently Asked Questions (FAQ)

Q: Why is the OPAA1DFL classified as obsolete? A: The OPAA1DFL is listed as obsolete by Dialight. The OPAA1DF represents the active product continuation within the OPA series for clear diffused lens sub-assemblies.

Q: What is the significance of the viewing angle difference between OPAA1DFL (12°) and OPAA1DF (10°)? A: Both parts are classified as diffuser-type lenses within the OPA series. The 2° viewing angle variation reflects design differences between specific lens configurations but does not affect mechanical form factor, mounting compatibility, or material composition. Selection should be based on the optical requirements of the target application.

Q: Are the OPAA1DFL and OPAA1DF mechanically compatible? A: Both parts share identical lens style (round with flat top), color (clear), transparency (diffused), and single LED configuration. The OPAA1DF specifies snap-in mounting and 26mm diameter dimensions. Mechanical compatibility depends on the original application's mounting interface and space constraints.

Q: What are the regulatory compliance differences? A: Both parts maintain identical REACH status (REACH Unaffected) and ECCN classification (EAR99). The OPAA1DF additionally specifies ROHS3 compliance, reflecting current environmental standards for active products.

Q: Is inventory availability a factor in substitution? A: The OPAA1DF has confirmed inventory of 1882 pcs in stock, providing immediate procurement availability. The OPAA1DFL, being obsolete, has limited availability (906 pcs noted as new original stock).

Q: What material is used in the OPAA1DF lens? A: The OPAA1DF is manufactured from acrylic, a standard material for diffused optical lens applications in the OPA series.
