OPIO1DIF13 Equivalent & Substitute Parts

Part Overview

The OPIO1DIF13 is a clear lens sub-assembly manufactured by Dialight, designed for use with Nichia LEDs. This component features a 12° spot optical pattern with a 26mm diameter round flat-top lens geometry. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OPIO1DIF13 is determined by the following critical parameters:

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

The OPAA1DF substitute maintains compatibility across these core parameters. Variations in viewing angle (12° versus 10°) and optical pattern classification (spot versus diffuser) represent acceptable engineering trade-offs within the lens sub-assembly category, provided the mechanical and environmental specifications remain aligned.

Parameter Comparison

Engineering Selection Recommendations

The OPAA1DF is an active production substitute for the obsolete OPIO1DIF13. Both components share identical mechanical dimensions (26mm diameter round flat-top lens), material transparency (diffused clear), and environmental compliance ratings (MSL 1, REACH Unaffected, EAR99 classification).

The OPAA1DF provides the advantage of active product status with current manufacturing support. The snap-in mounting type offers improved assembly integration compared to the unspecified mounting of the original part. Both components maintain equivalent moisture sensitivity and regulatory compliance profiles.

The 2° reduction in viewing angle (10° versus 12°) and the shift from spot to diffuser optical pattern represent optical characteristic differences that must be evaluated against specific application requirements.

Frequently Asked Questions (FAQ)

Q: Can OPAA1DF directly replace OPIO1DIF13 in existing assemblies?

A: Mechanical compatibility is confirmed through matching lens diameter (26mm), lens style (round with flat top), and mounting interface. Optical performance differences (viewing angle and pattern type) require application-specific validation.

Q: What is the significance of the viewing angle difference between these parts?

A: The OPIO1DIF13 provides a 12° viewing angle, while the OPAA1DF provides 10°. This represents a narrower light distribution cone in the substitute part. System optical design must accommodate this specification change.

Q: Does the snap-in mounting type of OPAA1DF affect compatibility?

A: The OPAA1DF specifies snap-in mounting, whereas the OPIO1DIF13 mounting type is not specified in available documentation. Assembly interface compatibility must be confirmed against the host system design.

Q: Are environmental and regulatory compliance ratings equivalent?

A: Yes. Both parts share identical Moisture Sensitivity Level 1 (Unlimited), REACH Unaffected status, and EAR99 ECCN classification, confirming equivalent environmental and export compliance profiles.

Q: Why is OPIO1DIF13 classified as obsolete?

A: Obsolete status indicates the part is no longer in active production. The OPAA1DF represents the active production alternative within the Dialight lens sub-assembly portfolio.
