OPTX1DIF8 Equivalent & Substitute Parts Reference

Part Overview

The OPTX1DIF8 is a clear lens sub-assembly manufactured by Dialight, designed as a 10° spot optical component for LED applications. This part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement.

The OPTX1DIF8 features a 26mm diameter round lens with flat top design and diffused transparency characteristics. Its obsolete status necessitates evaluation of active substitute components that maintain compatibility with existing designs while ensuring continued availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OPTX1DIF8 is determined by alignment of the following critical parameters:

• Lens size: 26mm diameter
• Lens style: Round with flat top configuration
• Color: Clear
• Lens transparency: Diffused
• Viewing angle: 10°
• Number of LEDs: 1
• Moisture sensitivity level: 1 (Unlimited)

The OPAA1DF substitute part maintains these core optical and mechanical specifications, ensuring functional compatibility in applications originally designed for the OPTX1DIF8. The primary distinction lies in mounting methodology and product status classification.

Parameter Comparison

Engineering Selection Recommendations

The OPAA1DF represents the primary active substitute for the obsolete OPTX1DIF8. Both components share identical optical specifications including 26mm diameter, clear diffused lens, 10° viewing angle, and single LED configuration. Both maintain MSL 1 (Unlimited) moisture sensitivity classification and REACH Unaffected regulatory status.

The OPAA1DF is currently in active production status with documented inventory availability, addressing the supply discontinuation of the OPTX1DIF8. The snap-in mounting methodology of the OPAA1DF requires mechanical compatibility verification with existing socket or housing designs originally specified for the OPTX1DIF8.

Compliance certifications (REACH, ECCN EAR99) are equivalent between both components, supporting direct substitution from a regulatory standpoint.

Frequently Asked Questions (FAQ)

Q: What are the critical parameters that determine if OPAA1DF can substitute for OPTX1DIF8?

A: The lens diameter (26mm), lens style (round with flat top), color (clear), transparency (diffused), and viewing angle (10°) must match. Both components meet these criteria. The primary consideration is mounting type compatibility, as OPAA1DF uses snap-in mounting.

Q: Why is the OPTX1DIF8 classified as obsolete?

A: The OPTX1DIF8 has been discontinued by the manufacturer. The OPAA1DF serves as the active replacement component with equivalent optical performance.

Q: Are there regulatory or compliance differences between OPTX1DIF8 and OPAA1DF?

A: No. Both components share identical REACH status (REACH Unaffected) and ECCN classification (EAR99), supporting direct substitution from a compliance perspective.

Q: What is the difference between "Spot" and "Diffuser" optical patterns?

A: This parameter distinction is noted in the data provided. Functional compatibility depends on the specific application requirements and optical performance expectations of the original design.

Q: Does the snap-in mounting of OPAA1DF affect substitution feasibility?

A: Mounting type compatibility must be verified against the original socket or housing design. If the OPTX1DIF8 used a different mounting methodology, mechanical integration of the OPAA1DF requires design review.
