OPAA1DF Equivalent & Substitute Parts

Part Overview

The OPAA1DF is a lens sub-assembly manufactured by Dialight, designed as a clear 10° diffuser snap-in lens for LED applications. This component is part of the OPA series and is actively produced. The OPAA1DF serves as a primary optical element for directing and diffusing light output in LED indicator assemblies compatible with Osram LED sources. Substitute parts are identified to provide alternative optical characteristics while maintaining mechanical and electrical compatibility within the same product family.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the OPAA1DF are identified based on strict mechanical and material compatibility criteria. The following parameters must remain constant for substitution eligibility:

• Lens Size: 26mm Dia
• Mounting Type: Snap-In
• Material: Acrylic
• Color: Clear
• Lens Transparency: Diffused
• Series: OPA
• Base Product Number: OPAA1
• For Use With/Related Manufacturer: Osram

The primary variable parameter that distinguishes substitute parts is the Optical Pattern and corresponding Viewing Angle. The OPAA1DF features a diffuser optical pattern with a 10° viewing angle. Substitute parts may employ alternative optical patterns (such as elliptical/oval) with different viewing angle specifications, provided all mechanical and material parameters remain aligned.

Parameter Comparison

Engineering Selection Recommendations

Both OPAA1DF and OPAA1OSL are active products manufactured by Dialight and meet identical regulatory compliance requirements: ROHS3 Compliant, REACH Unaffected, and EAR99 classification. Both components share identical mechanical specifications (26mm diameter, snap-in mounting, acrylic material) and are designed for use with Osram LED sources.

Selection between these parts is determined by optical performance requirements. The OPAA1DF provides a symmetric 10° diffuser pattern suitable for applications requiring uniform light distribution. The OPAA1OSL provides an asymmetric 8° x 54° elliptical/oval pattern for applications requiring directional light control in one axis while maintaining broader distribution in the perpendicular axis.

Frequently Asked Questions (FAQ)

Q: Can OPAA1OSL be used as a direct replacement for OPAA1DF?

A: Both parts share identical mechanical and material specifications and are mechanically interchangeable via snap-in mounting. However, they produce different optical patterns. The OPAA1DF generates a symmetric 10° diffuser pattern, while OPAA1OSL generates an asymmetric 8° x 54° elliptical/oval pattern. Selection depends on the required light distribution characteristics for the specific application.

Q: Are there packaging differences between these parts?

A: Yes. OPAA1DF is supplied in Bag packaging, while OPAA1OSL is supplied in Bulk packaging. This distinction affects handling and inventory management but does not impact functional or mechanical compatibility.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both OPAA1DF and OPAA1OSL are ROHS3 Compliant, REACH Unaffected, and classified as EAR99. Both carry MSL Rating 1 (Unlimited), indicating no moisture sensitivity constraints.

Q: What is the base product relationship between these parts?

A: Both parts share the base product number OPAA1, indicating they are variants within the same optical lens family designed for the OPA series assemblies.
